continental prop strike ad

The argument goes would you rather be paying for an in flight engine failure 100 hours from now. on Aircraft was involved in a prop strike. Since that time, the FAA has obtained information regarding 13 crankshaft failures. the Federal Register. Service Bulletin 533A has the pertinent Lycoming prop-strike definitions for all Lycoming direct drive engines. 533A, which is dated in 1999, five years earlier than AD 2004-10-14, and four years earlier than SB 475C. The alternator is turning 3000 rpm because of gearing. 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. The $8,500 differential is not insignificant. Years ago, everyone would have filed off the other blades and not thought twice about it, but today, this engine disassembly requirement and prop inspection and repair ended up costing the owner around $5,000. 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. the material on FederalRegister.gov is accurately displayed, consistent with If you need someone to remove and reinstall the engine, that's another $1,800. The engine SN can be found in logbooks or other maintenance records. What this all boils down to is that in the case of any accidental damage to a propeller installed on a aircraft operating under Part 91 of the FARs, it is up to the inspecting mechanic to determine if the engine should continue in service without total disassembly and inspection, or only the SB 475C level of inspection if a Lycoming engine falls into that category. On Lycoming engines, which are not nitrided, the flange can be bent. This prototype edition of the A propeller strike, no matter how minor the incident, should not be ignored. Even if theres no visible damage to the propeller, there may be hidden internal damage to the propeller, governor, crankshaft, and other components that can cause engine failure later in the engines life, if not immediately. Then, put the pieces of the puzzle together for your customer and explain what needs to be done. 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. continental prop strike ad. Mahlon Russell, production manager for Mattituck Aviation Corporation, an engine overhauler in Mattituck, NY, says, "The only pertinent FAA definition that I have been able to find for sudden stoppage' is in Advisory Circular 43.13-1A. These tools are designed to help you understand the official document (ii) If TCM notifies you that the crankshaft is serviceable, the propeller assembly may be reinstalled. This is not restricted to propeller strikes againstthe ground. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Putting the puzzle together better and aid in comparing the online edition to the print edition. Unless, of course, you're not concerned about regulations or insurance issues, the general approach to how to handle a prop strike situation for the average maintenance shop has become quite, shall we say, conservative. Lycoming is particularly concerned with this area and outlines specific inspection criteria with the force of AD 2004-10-14 to support their bulletin SB 475C depending on engine model. include documents scheduled for later issues, at the request Replace the rotobroach after the sixth core sample, or before if the rotobroach does not cut with the maximum torque applied. Register, and does not replace the official print version or the official Studies have shown that a 100-amp alternator can impose a. My investigation started with my need for another engine for my Cessna 210. 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. I took the ad to an engine overhaul shop, Corona Cylinder and Engine Overhaul in Corona, California, and had the owner, Joe Anderson, call the person selling the engine. My investigation started with my need for another engine for my Cessna 210. Although not a guarantee of any kind, the lack of movement showed that utter destruction had not occurred. So, in a roundabout way by the last paragraph, Lycoming is saying its the repair facilitys call unless your engine is one found in the later AD 2004-10-14, which applies to a lot of Lycoming engines. The decision was made for me by an advertisement in Trade-A-Plane. Or it could be an engine with illegal performance enhancements for a certified engine such as shaved decks to increase compression. Assistant Manager, Engine and Propeller Directorate, Aircraft Certification Service. The minor propeller repair must be accomplished in accordance with the propeller manufacturers published instructions (if it exists) for the minor damage preferentially over more general AC 43.13-1B with the exceptions we noted earlier). Off the record, most of the shop owners said they find evidence of internal damage in only about 10 to 20 percent of the engines they've torn down. Lycoming makes the point that an overstressed crankshaft gear dowel pin can ultimately shear, causing all power to be lost. In short, all accessories become suspect to damage under either a prop strike or sudden stoppage incident. Most insurance carriers don't want to face the prospect of the engine or propeller leaving the aircraft due to a prop strike!". Just a few short months ago, Textron Lycoming's Service Letter L-163C recommended taking the engine apart for inspection following any incident involving propeller blade damage. It is Service Bulletin 96-11A, and this is the pertinent section: "Part 1Propeller strike incidents. Maybe it is and maybe it isn't." for better understanding how a document is structured but Thread starter kevmor99; Start date Sep 28, 2016; K. kevmor99 the most are "prop strike." Russell explains, "Aircraft operating under Part 135 of the FARs must comply with all manufacturer's service bulletins, and would have to comply with Service Bulletin 96-11 requiring total disassembly and inspection after any incident that required removal of the propeller for repairs or if the engine physically lost rpms during the incident. 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 1, 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. Compliance with this service bulletin is mandatory per AD 91-14-22. Issued in Burlington, Massachusetts, on November 13, 2000. Also, some engines with a gear-driven alternator have a large, relatively thin and very vulnerable gear bolted to the forward end of the crankshaft. 01/17/2023, 249 TCM-powered aircraft operating under Part 135 of the FARs that have to comply with all manufacturers service bulletins would have to comply with Service Bulletin 96-11B, dealing with prop strikes, dated July 2008, requiring total disassembly and inspection after any incident that requires removal of the propeller for repairs or if the engine physically lost any rpms during the incident. You can bet the fellow who hit the traffic cone never made a logbook entry unless the engine had to be repaired. This could indicate a gear-up landing, or other source of damage that took time to fix. Following any propeller strike, complete disassembly and inspection of all rotating engine components is mandatory and must be accomplished prior to further flight. A prop strike-per the manufacturer and FAA definition is not often found to be minor other than the occasional small stone picked up causing minor blade damage but no rpm loss or prop removal is required for the repair, and those are key elements on the need for an engine tear-down-engine rpm loss or sudden stoppage from the strike. Even tip damage is considered cause for teardown The thought of the damage and cost involved makes all of us shudder. 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. 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. At Unlimited Aero Engines we know that things happen, and happen fast. DeJoris explains, "Take for example the prop governor drive the rotating mass in the prop governor, mainly the flyweight assembly can really be problem if suddenly stopped.

The President of the United States communicates information on holidays, commemorations, special observances, trade, and policy through Proclamations. from 54 agencies. The answer is yes, you can ignore the directive to the same degree that any one who operates under Part 91 does with any other service directive without the force of an AD behind it. documents in the last year, 41 '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." Either may require additional inspection but neither may negate the inspections required by the FARs. Forums. 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. This dream price just may be the cast off of a prop-strike incident that has been covered up or minimized in some way-or a prop with blades that are out of spec from metal removed from previous overhauls. I won't list them all here, but some of the more expensive ones are: hydraulic valve lifters, connecting rod bearings, the crankshaft's main and thrust bearings, all needle, ball, and roller bearings, exhaust valves, valve springs, piston pins, pistons, crankcase through bolts, all the hardware, seals, gaskets, O-rings, and lots of other small stuff. continental prop strike ad 21 May. This amendment is prompted by reports of crankshaft failures, and by the addition of additional crankshaft serial numbers (SN) that have been added to the suspect population. More information and documentation can be found in our on documents in the last year, 675 A propeller strike (according to this Lycoming bulletin) is defined as follows:(It has all the same definitions found in AD 2004-10-14 that we printed in italics but has additional information): Circumstances 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. Continental Motors states: 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 K. kevmor99. Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the Atlanta ACO. It defines a sudden engine stoppage as; stopping an engine in one revolution or less for any reason, be it from propeller impact or from an engine failure of some sort. documents in the last year, 28 Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed. This feature is not available for this document. The simple physics of a prop strike, in our opinion, makes a compelling case for an internal engine inspection with visual and thorough NDT techniques. All rights reserved. In the case of any accidental damage to a propeller installed on a aircraft operating under Part 91 of the FARs, it is ultimately up to the inspecting technician to determine if the engine should continue in service without total disassembly and inspection. 01/17/2023, 159 Some reports are quite specific about a recent prop strike in the engines history. John Schwaner, author of the Sky Ranch Engineering Manual, a must have for all those interested in aircraft engines, and owner of Sacramento Sky Ranch, in Sacramento, California, said the quandary is, "How do you know if something is good or not? If you can imagine a loose rod banging around inside your engine, you know it's bad. However the dates that the engines and crankshafts were delivered may not coincide with their dates of manufacture. Still others will only pay for the labor to do the job and will not pay for any parts. Now because of the extent of disassembly required to inspect the gear, you end up performing other maintenance as well.
