These counterweights move on relatively soft bushings. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. This damage can result in catastrophic engine failure. DeJoris, who deals with propeller strike issues quite frequently says, "We recently had a customer with a prop strike who struck a steel stake that cut 1/4-inch of the tip off one blade of a three bladed prop. Disregard the letter R.. According to DeJoris, "Hartzell requires hub replacement if any blade in the assembly is bent beyond repair limits due to impact damage. Prop strike on Continental. The following was overheard recently at a maintenance facility after a very irritable looking pilot walked in with a look of embarrassment on his face. Another thing to look for in the logs is a prolonged period of inactivity, such as years between annual inspections and oil changes. Everyone was happy and the prices were right. CONTINENTAL TSIO-520-J $18,995 FOR SALE Engine with Accessories TSMO=488.2 No Prop Strike Photos, logs, details per request. They either read full or This article originally appeared in the December 2012 issue of Light Plane Maintenance. Second, any time foreign object damage requires propeller removal for repairs other than the minor dressing of the blades as mentioned above, the incident is considered a propeller strike and must be inspected as outlined in SB 96-11B. (iii) Maintain a record of each core sample obtained with each rotobroach bit used. Moreover, the crank is not the only critical element in a prop-strike incident. Textron Lycoming must take the position that in the case of a sudden engine stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip, the safest procedure is to remove and disassemble the engine and completely inspect the reciprocating and rotating parts including crankshaft gear and dowel parts. This occurred during several discrete periods, i.e. If you can imagine a loose rod banging around inside your engine, you know it's bad. And what's a "solid object?" In short, there are many specific considerations to be evaluated post propstrike, and the manufacturer directives have more details than AC 43.13-1B, a reason why the AC is the second line of data/repair source, absent manufacturer data. SUMMARY: The FAA is adopting a new airworthiness directive (AD) that supersedes an existing AD, for Lycoming Engines (formerly Textron Lycoming), direct-drive After the extent of the inspection has been determined, it is important, as with any major repairs that are accomplished on your aircraft, to find out exactly what is included in the estimate to repair your engine following a prop strike. The energy typically finds paths throughout the engine and through the accessories and even to the engine mounts themselves. My investigation started with my need for another engine for my Cessna 210. A tear down of most direct drive engines isnt a major repair but we recommend using a certified repair station or the factory for that action as well as the level of NDT testing will be significant and required to be done by certified people for such critical NDT inspections. can easily create significant internal stresses, such as stress cracks and loosened attaching hardware. 49 U.S.C. and services, go to These markup elements allow the user to see how the document follows the 533 called "Recommendations Regarding Accidental Engine Stoppage, Propeller/Rotor Strike or Loss of Propeller/Rotor Blade or Tip.". electronic version on GPOs govinfo.gov. Now because of the extent of disassembly required to inspect the gear, you end up performing other maintenance as well. Conditions which surround accidents are many and varied; therefore the circumstances of the accident can not, in our opinion, be used to predict the extent of the damage to the engine or assure its future reliability. This repetition of headings to form internal navigation links A propeller strike can occur at taxi speeds and during touch-and-go operations with propeller tip ground contact. Both major engine manufacturer's have service literature that explains the desired course of action after accidental propeller damage and, in the case of Teledyne Continental, defines what their interpretation of a propeller strike is.". documents in the last year, 1401 (ii) You may use each rotobroach bit to obtain up to six core samples. As for whether the inspection should be done, Anderson said he couldn't answer for anyone but himself; however, he wouldn't hesitate if it were his engine. FIND A DEALER. If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. But let me start this section with a caveat: There is no black and white, and the subject under discussion is the grayest of the gray areas. Sure, some of these arguments are specious, but the point is, there's a lot of gray area, and this can cause many incidents to be ignored. The actions are required to be accomplished in accordance with the service bulletin described previously. Lycoming's Service Bulletin 475B requires that in the event that the engine has experienced a propeller strike, inspection and possible rework of the accessory gear train as well as the rear of the engine's crankshaft is required. Talking about whether to have the engine overhauled or just inspected, Tunnel said it can be penciled out. To be undiplomatic, dialing in a crank after a prop strike or sudden stoppage as has been defined by both the manufacturers and the FAA is essentially a fools errand-at least as possible decision making criteria on the serviceability of the crank. The President of the United States issues other types of documents, including but not limited to; memoranda, notices, determinations, letters, messages, and orders. No more filing blades a bit shorter after a tip strike, or performing a run-up and signing off on an engine after the runway lights have been mowed a bit shorter. Are there any hidden costs? for better understanding how a document is structured but A bit of homework will go a long way towards helping you persuade your customer to do the right thing. If you've attended AirVenture or any of the other major airshows, you've heard it. This feature is not available for this document. The degree of difficulty of this action will bevaried, depending on the installation and location of accessories, turbos, intercoolers, etc. Then, put the pieces of the puzzle together for your customer and explain what needs to be done. This is a minor or major prop repair issue, but not a potential engine tear down issue. Prior to any ground operation of the engine assure that the propeller flange and the crankshaft flange area are free of any crack indications in addition to the engine component inspection. The deffination of a prop strike is different on Lycomings than Continentals, Lycoming says any time a prop strikes any thing that will cause a loss of RPM it is a prop strike. continental prop strike ad continental prop strike ad. #1. I alluded to the potential of buying an airplane that suffered a prop strike without the required inspections being completed. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Any decision to operate an engine which was involved in a sudden stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip without such an inspection must be the responsibility of the agency returning the aircraft to service. All of the fractures have been grouped around certain manufacturing dates between April 1, 1998, and March 31, 2000, inclusive. After finding out the answer to these questions, its time to discuss with your insurance company what it will pay for and what it wont, before its a big surprise after the inspection is done. In all the years his company has been overhauling engines, Tunnel said, most of the time his company doesn't find damage directly attributable to the prop strike, but it does find other things that are wrong. We will not be discussing damage to the prop in this article since there is so much information on prop damage that does not involve engine tear downs. They all agreed that if it were their aircraft, they would think long and hard about doing a teardown and inspection. as a result of sudden stoppage. Lycoming, in their prop-strike Service Bulletin 533A, takes the approach that the safest procedure is to take the engine apart for inspection following any incident involving propeller blade damage. These tools are designed to help you understand the official document documents in the last year, 946 Russell says, it should be noted that to comply with A.D. note 91-14-22, the engine does not need to be completely disassembled and that access to the accessory gear train can be accomplished, in most cases, with the engine still installed in the aircraft. Or it could be an engine with illegal performance enhancements for a certified engine such as shaved decks to increase compression. Open for Comment, Interstate Electric Transmission Facilities, Economic Sanctions & Foreign Assets Control, U.S. the most are "prop strike." Others will pay for all costs for the inspection and for any parts needed due to the incident. How much grass and how deep should the water be, and how sudden is "sudden," and what constitutes an rpm drop? In light of the preceding information, would you be comfortable doing that? However, they have the caveat that the inspecting mechanic may override that position and return the engine to service without disassembly and inspection if he or she feels that it is the prudent and responsible thing to do. On severe prop strikes, the mounts can be easily twisted and loaded in a way that it was not designed to withstand," he says. I've heard that a Continental doesn't require a tear They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage. headings within the legal text of Federal Register documents. K. kevmor99. The oil pump on the Continental IO-360 is driven by a very small shaft, for instance, and can be easily sheared as a result of a strike," says DeJoris. documents in the last year, 90 Document Drafting Handbook It turned out to be a salvage shop and the owner confirmed that the logs for the engine were available, and the crank had been dialed, and found to be OK. Dialing checks the run-out, which is the amount of movement at the flange when the crank is rotated. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. You can bet the fellow who hit the traffic cone never made a logbook entry unless the engine had to be repaired. 2 Blade Continental O-200/Lycoming O-235 Ground Adjustable STOL Propeller $ 74CK $ 76AK-2 $ FIND A DEALER NEAR YOU. We get e-mail from readers who have had what they often prefer to call prop incidents as to possibly avoid the term prop-strike, and its frequent need for a recommended or mandatory engine tear down. Schwaner made the point that more than a few people have been told their engine's crank is bad, but it just so happens that the shop has the one you need in stock. Sticking with a certified repair facility possessing all the skills and tools will probably reduce the extra shipping costs and time involved to get individual parts examined seems most efficient to us. He used a football analogy of a player who can be brutally tackled and get right up, then trip over a bucket and break his leg. Its possible to do major engine/accessory damage without obviously damaging the prop by hitting water or heavy, tall grass that stops or slows the running engine. After defining a prop strike, TCM's SB 96-11A states: "A. For complete information about, and access to, our official publications For those engines that were overhauled in the field with factory new crankshafts, the crankshaft SN should be shown in work orders, log books or other maintenance records. Lycoming has reports of ground strikes, which have resulted in overstressed connecting rod bolts, that failed later. are not part of the published document itself. The OFR/GPO partnership is committed to presenting accurate and reliable The FAA has determined that all of the defects were due to unique material composition characteristics combined with process control variations that occurred during the material melt process. Unfortunately, it may be the next owner who discovers any hidden damage. The general consensus is that at least some degree of tear-down is the only safe option under their definition, and largely follows manufacturer data in the general damage/repair evaluation techniques. And again, Chapter 8 of AC 43.13-1B is a good place to start gathering unbiased information. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. How much more time before overhaul is remaining on the engine? How much liability insurance do you have? Federal Register issue. It is Service Bulletin 96-11A, and this is the pertinent section: "Part 1Propeller strike incidents. A slam stop will detune the weights and damage the bushings so they can no longer do their job of helping to balance the crank while operating. Aircraft Owners & Pilots Association Find it free on the store. [FR Doc. Register (ACFR) issues a regulation granting it official legal status. The prop had a good-size dent in it, prompting the pilot to remove the prop and send it in for repair. The decision was made for me by an advertisement in Trade-A-Plane. Below are three important links from the FAA, Lycoming, and Teledyne Continental regarding the definition of a Prop Strike and sudden stoppage. Sep 28, 2016. 13132, because it would not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved Click here for the Diesel Engines service bulletins.

New Documents The thought of the damage and cost involved makes all of us shudder. And two, "The preceding definitions include situations where an aircraft is stationary and the landing gear collapses causing one or more blades to be substantially bent, or where a hangar door (or other object) strikes the propeller blade. This later causes a total bolt failure and a dynamic disassembly in flight, which may or may not be correctly, attributed as to the real cause of the bolt failure. This damage can result in catastrophic engine failure. Basically anything that moves is subject to visual and other forms of nondestructive testing. 01/17/2023, 284 The defects were not revealed during manufacture because specification material evaluation techniques were inadequate to detect these anomalies. 1 in 2022, Southwest To Build Aircraft Hangar, Create 100 Jobs at Reid Airport, Boeing, United Airlines Finalize 737 MAX and 787 Order, Including Record Purchase for 100 Dreamliners. This amendment supersedes emergency airworthiness directive (AD) 2000-08-51. The pins are more than adequate for running loads, but they are totally inadequate when you subject them to sudden stoppage. He also said that if you have a prop strike while traveling, don't go to the first shop you see and turn the airplane over to it. Now I had to determine the consequences. Its not a smoking gun, but perusing the accident reports makes one wonder about such coincidences. The pressure from an owner to ignore the engine and fix the prop may be great, but it is certainly in the best interest of the mechanic's career to persuade the owner that any amount of damage to the propeller constitutes the need for a thorough inspection. 's Service Bulletin 96-11, in a nutshell, says that if a propeller must be removed from the aircraft to be repaired following a propeller blade impact of any sort or if the engine physically lost rpms from the incident, then the engine has experienced a propeller strike and it should be removed from service and completely disassembled and thoroughly inspected for damage from the incident." We can even see situations where a prop sustains a fairly nasty nick in a gravel strip, but no rpm loss occurs or serious blade damage occurs. For example, how much propeller filing constitutes "minor dressing?" You will note TCM does not get into the concept of sudden stoppages possibly being handled differently as Lycoming does. Some geared alternators shafts use gears that are designed to slip on overloads, but older versions of this alternator gear do not have this design, and the gear shear design is for an alternator failure not a crank stoppage. It is recommended that the technician views and understands Instructional Video for Compliance with Teledyne Continental Motors Mandatory Service Bulletin MSB 00-5C before performing these procedures. Per the Lycoming website it is still an active bulletin, which we quote in part as follows: (It has all the same definitions found in AD 2004-10-14 that we printed in italics but has additional information): FAA Partners With Korea On Advanced Air Mobility, Guest Blog: Why Aircraft Engines Should Be Hard To Start, Southwest: The Ghost Of Jack Welch Part II, And Now, A ChatBot For All Your Aviation Questions, Best Of The Web: How The Rolls-Royce Merlin Became A World, Best Of The Web: Why Wingsuits Are Flight As Pure As, General Aviation Accident Bulletin, January 16, 2023, Top Letters And Comments, January 13, 2023, National Museum Of The U.S. Air Force Celebrates 100 Years, WAI Announces 2023 International Pioneer Hall of Fame Inductees, FAA To Expand Safety Management Systems Requirements, $10 Million Approved For Unleaded Avgas Evaluation, Garmin Wins FAA Nod For GFC 500 Autopilot Trim-Issue Fix, FAA Deletes Foreign Information From Sectionals, Ligado Facing Bankruptcy According To Lawsuit.

We have personally seen an instance where a plane lost the entire prop in flight following a so called minor prior strike of hitting a runway light while taxing, but the crank on the IO-520 was only checked for run-out and prop repaired (and this was a Part 135 operated plane). Well, for one i dont think i want to take out any of the clubs planes ever again. The other thing to consider is all of the accessories on the engine or parts of the engine that are spinning at high speeds that could come If possible, he suggests, mark the flange somehow, or take a photo of the scratches and nicks so you can compare it to the "new" one later. Definition of Propeller Strike (i) For the purposes of this AD, a propeller strike is defined as follows: (1) Any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades. Our designation as a Cessna Service Center and authorization as a parts and engine distributor for both Lycoming and Continental Lycoming's new SB seems to generalize the term propeller strike and sudden stoppage to be quite inclusive. Compliance with the requirements of this AD is required within the next 10 hours time-in-service from the effective date of this AD, unless already done. Continental Properties has earned a spot on the National Multifamily Housing Council's (NMHC) list of the Top 10 developers in the country. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Atlanta Aircraft Certification Office (ACO). These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal.". Panagotacos recently paid $66 for the list of a 1956 Cessna 182, which is in his shop. Forums. As mentioned earlier, Advisory Circular 43.13-1B, Chapter 8 defines a sudden engine stoppage as stopping an operating engine in one revolution or less for any reason, period, and includes prop-strike damage as a subset of the of sudden stoppage definition (at least the way we interpret the way it is written). Pre-Flight. Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. Bending loads alone are not the only destructive element, and nondestructive testing of the entire crank and associated structures is the only reasonable way to check it out. Comments may also be sent via the Internet using the following address: 9-ane-adcomment@faa.gov. Comments sent via the Internet must contain the docket number in the subject line. Refer McCauley Service Bulletin 137W. If you need someone to remove and reinstall the engine, that's another $1,800. On TCM engines with the geared alternators up front, he has seen the mounting flange and the gear drive bolts break during a prop strike. Use the PDF linked in the document sidebar for the official electronic format. But if there's 1,000 hours or more left on the engine, you're probably better off with just an inspection. So, when it comes time for that prop strike/sudden. While every effort has been made to ensure that Register, and does not replace the official print version or the official of the issuing agency. (2) After obtaining the results of the core sample evaluation, disposition the crankshaft as follows: (i) If TCM notifies you that the crankshaft is not serviceable, replace the crankshaft with a serviceable crankshaft of the same part number before further flight. On the record, owners said that if someone came into their shop and said he or she had an aircraft with a prop strike, they would follow the procedures outlined above to the letter.

Dye Penetrant test didn't show any cracks on the flange, runout is .001 which is well within tolerance. There is also a measure of anecdotal evidence in the engine accident/incident statistics that engines that have a prop strike/sudden stoppage and owners who did not follow the manufacturer recommendations such as only checking the crankshaft run-out, have a higher incidence of broken cranks or other engine failures a number of flight hours later. provide legal notice to the public or judicial notice to the courts. Be especially wary if this is some form of private cash sale that has to be done right away, unless you are planning to have it torn down and rebuilt by a shop with the right inspection equipment to inspect for crank and gear damage, and be prepared for costs potentially exceeding a factory reman engine i.e. Re: O-360 propeller indexing (noticeable slight vibration) Lycoming O-360 A-1As (and every other O-360 Ive met) propellers should be indexed such that the propeller stops at the 10 and 4 o'clock position (viewed from the front facing aft) when the engine shuts down. A propeller strike is: (1) any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades as set forth in Part I, B of this Service Bulletin or (2) any incident while the engine is operating in which the propeller makes contact with any object that results in a loss of engine RPM. As he approached the director of maintenance he asks, Pilot: "When does a prop strike require engine tear-down and inspection?
