TCM is less equivocal. 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. Think of it as the equivalent of a high-speed twist drill, with great resistance to bending-it tends to snap or develop cracks from damage and fails suddenly. publication in the future. 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. Comments may also be sent via the Internet using the following address: [email protected]. Comments sent via the Internet must contain the docket number in the subject line. Although not a guarantee of any kind, the lack of movement showed that utter destruction had not occurred. 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. This airworthiness directive (AD) applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. What other services or inspections are being performed at the same time as the inspection? Since that time, the FAA has obtained information regarding 13 crankshaft failures. Dealing with them on this issue is fodder for another article, however. Compliance with this service bulletin is mandatory per AD 91-14-22. (ii) If TCM notifies you that the crankshaft is serviceable, the propeller assembly may be reinstalled. Lycoming also has a short, two-page separate, specific prop-strike bulletin, SB533A, which is dated in 1999, five years earlier than AD 2004-10-14, and four years earlier than SB 475C. Secure the airplane and figure that it will be out of commission for a few months. For crankshafts identified in paragraph (a) of this AD, TCM has already determined which engines have a new suspect crankshaft installed and have identified those engines by engine SN. 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. AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -. You will note TCM does not get into the concept of sudden stoppages possibly being handled differently as Lycoming does. After defining a prop strike, TCM's SB 96-11A states: "A. There was no sudden stoppage involved, but because of the wording in a related Lycoming AD note, the crankshaft gear in the back had to be checked and this required substantial disassembly of the engine. Accordingly, the FAA has not consulted with state authorities prior to publication of this proposed rule. These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal.". This document has been published in the Federal Register. 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. This article originally appeared in the December 2012 issue of Light Plane Maintenance. 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. Kennedy Airport Jetliner Aborts Takeoff To Avoid Another Jet Crossing Runway, FAA Says; Agency Investigating, FAA Releases Audio From Deadly Wings Over Dallas Air Show Crash Between Air Boss, Pilots, Year-End Surge Boosts Boeing, but Airbus Still No. documents in the last year. I've heard that a Continental doesn't require a tear down and inspection as a Lycoming does, but looking at Continental's Service Bulletin SB96-11B it looks Home. MSB 005C lists additional serial numbers (SN's) of affected engines and suspect crankshafts that were manufactured between April 1, 1998, and March 31, 2000, inclusive. The one that came with the airplane had passed TBO (time between overhauls) but its logbooks didn't go back to when it came from the factory. At Unlimited Aero Engines we know that things happen, and happen fast. "You naturally think of the crankshaft and things that are directly connected to the engine, but you don't think of other accessories. 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. Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the Atlanta ACO. the material on FederalRegister.gov is accurately displayed, consistent with better and aid in comparing the online edition to the print edition. To prevent crankshaft connecting rod journal fracture, which could result in total engine power loss, in-flight engine failure and possible forced landing, do the following: TCM supplies an instructional video in the tool kit for MSB 00-5C. the Federal Register. FAA# JL4R288M | EASA.145.4115 | Toll Free: 800-282-3202 | 954-970-3200 It pretty much echoes the TCM service bulletin but adds two other situations. documents in the last year, 534 Their decision would involve the specific engine involved, the severity of the prop damage, the cost, the time on the engine, whether the prop was stopped or appreciably slowed, who was flying at the time, what else is going on in the shop, and maybe the time of year and their mother's maiden name. On November 24, 1999, the FAA was notified of a crankshaft failure on a TCM engine. Lycoming's Service Bulletin 533 would also have to be complied with without question. Its entirely possible after a sudden engine stoppage for there to be severe internal damage and yet the prop looks perfectly OK even if the prop was either totally stopped or the rpm dropped by the incident. documents in the last year, 12 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. Either may require additional inspection but neither may negate the inspections required by the FARs. At what point after a prop strike do you need an engine teardown and inspection? Ken Tunnel of Lycon Aircraft Engines in Visalia, California, an engine facility used by a number of owners of show airplanes, said, "There's no way you can tell if there's any damage regardless of the circumstances. Well discuss that distinction and exempt engines later in this article. on FederalRegister.gov Highly stressed connecting rod bolts also take a beating from a prop-strike, which can cause a slight stretch. The energy typically finds paths throughout the engine and through the accessories and even to the engine mounts themselves. A Textron Lycoming engine, that is being operated on a Part 91 aircraft, that had a sudden engine stoppage, not a propeller strike, must comply with AD 91-14-22 and Service Bulletin 475B at a minimum. It still could end up at a prop repair station if inspection deems it a prop major repair requirement depending on manufacturer inspection criteria of the prop. So my question was, should I overhaul the present engine or look for one with good logs? He continues, "T.C.M. I wouldn't skimp on safety, but if I could save a few dollars on cosmetics, I sure would. For example, how much propeller filing constitutes "minor dressing?" corresponding official PDF file on govinfo.gov. Crankshafts with this type of subsurface defect will fail. The Lycoming information is more complicated and equivocating than the TCM directives in our opinion, as well explain. Yet, the company recently published a new Service Bulletin, SB No. (j) 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. Over the years, Continental has built a service offering for aircraft operators and owners These services include engine overhauls at the Continental factory service center for Continental, Titan, and LYCOMING engines, factory overhauls for Continental AvGas engines, sudden stoppage/propeller strikes, shock inspections, fleet overhaul programs, Jet-A burning engine documents in the last year, 1487 ", Case in point My investigation started with my need for another engine for my Cessna 210. documents in the last year, 946 Prop strike on Continental. Never allow an insurance adjuster to dictate the inspection requirements after an incident. More than the prop and crankshaft Inspect all engine accessories in accordance with the manufacturer's instructions.". Basically anything that moves is subject to visual and other forms of nondestructive testing. are not part of the published document itself. For complete information about, and access to, our official publications If the engine is being disassembled does the estimate include testing after reassembly? These tools are designed to help you understand the official document Propeller strike inspections. 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. Both Lycoming and Continental express concerns about prop-strikes causing damage to the rear of the crank in the vicinity of the rear radius of the oil slinger, which can be shoved back into the case rear. This site displays a prototype of a Web 2.0 version of the daily 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 Other Lycoming literature mentions the importance to check the accessories as does TCM. 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. 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. It also does not equivocate to any degree on an engine tear down being the mandatory procedure, which is described in the bulletin. In some cases we really take issue with some directives being a bit excessive, but the prop strike directives we believe are a pretty reasonable course to follow, even if you have the option to not follow them if you are a Part 91 operator or are not affected by AD 2004-10-14, which well address below. They all agreed that if it were their aircraft, they would think long and hard about doing a teardown and inspection. Talking about whether to have the engine overhauled or just inspected, Tunnel said it can be penciled out. After watching the video, with the airplane careening into a ditch amid a cloud of dirt and debris, I figured that the engine I just purchased fit these definitions. If you've attended AirVenture or any of the other major airshows, you've heard it. The concern, of course, is the prospect of hidden damage, which can cause, and has caused, subsequent engine failures. Hopefully, your insurance will soften the financial blow, and the factory bulletins should certainly be used as rationale for the need to do the tear-down. The FAA has reviewed and approved the technical contents of TCM Mandatory Service Bulletin (MSB) 005C, dated October 10, 2000. Sensenich Wood Propeller Co. 2008 Wood Court Plant City, FL 33563. How much grass and how deep should the water be, and how sudden is "sudden," and what constitutes an rpm drop? I bought the engine and started my quest to determine what I absolutely had to do to get the airplane airworthy. for better understanding how a document is structured but (f) This amendment becomes effective on December 12, 2000. what would martial law in russia mean phoebe arnstein wedding joey michelle knight son picture brown surname jamaica. The AD specifies the inspection at each engine overhaul, after a propeller strike, sudden stoppage, or whenever gear train repair is required. This year's numbers have placed us in the top 10, highlighting another strong year of property development. 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. documents in the last year, 16 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. The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order No. Thread starter kevmor99; Start date Sep 28, 2016; K. kevmor99 The investigation revealed that the crankshafts failed due to subsurface defects in the number one crankshaft connecting rod journal. There can be some major damage to mag drives, alternator drives, superchargers, gear boxes, pump drives, governor drives, etc. These markup elements allow the user to see how the document follows the That said, you'll understand that this article isn't going to state, or even hint at, what you should do in this situation. 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. Even tip damage is considered cause for teardown Do we think the engine makers are overly eager to have you tear down or dig into your engine? Say the engine is turning only 1000 rpm, barely above an idle. But what is a prop strike and what exactly are the ramifications? 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 The Lycoming information is more complicated and equivocating than the TCM directives in our opinion, as well explain. Also, on prop strikes involving frontal impact, the crank can be pushed back into the engine, cracking the case at the slinger ring, and this may not be visible. This feature is not available for this document. 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. 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. Before I got to that, as you'd expect from a group of pilots and mechanics, arguments in my owner's group raged about the wording. Note 10: 2400 hours TBO may apply. documents in the last year, by the Fish and Wildlife Service You are going to spend a lot of money, so make sure you are dealing with an honest and reputable shop. 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. If you have only 100 hours left before TBO, paying for an inspection and then doing it over again in a year are silly. 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. If it has, and there's no indication in the engine logs about a teardown and inspection, it's time for a long explanation from the seller. Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. The thought of the damage and cost involved makes all of us shudder. documents in the last year, by the Transportation Security Administration Maybe it is and maybe it isn't." Anderson, owner of Corona Cylinder and Engine Overhaul, said the cost of a teardown and inspection, for a small four-cylinder engine like the O-360 or -320, is about $4,000. 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. The $8,500 differential is not insignificant. Register (ACFR) issues a regulation granting it official legal status. by the Federal Energy Regulatory Commission He adds, "This limits their liability exposure. Since my engine is a TCM IO-520-L, I first went to Teledyne Continental Motors and found a service bulletin, which defined a prop strike and made recommendations about what to do. 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. K. kevmor99. AD/PROP/1 Amdt 2 (continued) Page 6 of 9 HOFFMAN (continued) Continental IO-346 engines 1000 All other Fixed Pitch Types 2000 Flottorp storage, overspeed, ground strike or aerobatic requirements refer mt-propeller Service Bulletin 1 Revision X. This Airworthiness Directive (AD) is applicable to Teledyne Continental Motors (TCM) IO-360, TSIO-360, LTSIO-360, O-470, IO-470, TSIO-470, IO-520, TSIO-520, LTSIO-520, IO-550, TSIO-550 and TSIOL-550 series reciprocating engines that were assembled, rebuilt, or overhauled using a crankshaft that was manufactured between April 1, 1998, and March 31, 2000, listed by engine and crankshaft serial number (SN) in TCM Mandatory Service Bulletin (MSB) 00-5C, dated October 10, 2000. Should he also have performed the obligatory engine inspections? What you see in the pictures is what you are getting. Includes: Fuel Injection Spyder Starter Alternator Bendix Magnetos Gamijectors I will be more than happy to ship this engine to you. 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. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. TCM mandatory service bulletin (MSB) 005B, dated May 25, 2000, and MSB 005C, dated October 10, 2000, were issued to include the SN's of those additional suspect crankshafts. 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. Although many in the industry still like to interpret rules to their advantage, the mechanic is being faced with fewer and fewer "outs" Sep 28, 2016. 552(a) and 1 CFR part 51. 2. continental prop strike ad continental prop strike ad. Below are three important links from the FAA, Lycoming, and Teledyne Continental regarding the definition of a Prop Strike and sudden stoppage. There's also the cost of inspection of the accessories, which is extra. 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. Copies may be inspected at the FAA, New England Region, Office of the Regional Counsel, 12 New England Executive Park, Burlington, MA; or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC. Propeller inspections are fairly clear cut damage on the blades is typically quite apparent, and the existence of damage beyond field repair limits dictates that the unit is disassembled and given a searching internal inspection, and in some cases, complete overhaul. They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage. These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal. On Lycoming engines, which are not nitrided, the flange can be bent. (iv) Do not exceed the torque limits specified in TCM MSB 00-5C, dated October 10, 2000, when obtaining the core sample. Moreover, the crank is not the only critical element in a prop-strike incident. This is not restricted to propeller strikes againstthe ground. Factory New & Factory Rebuilt Gasoline Engines +1.251.436.8101 08:00 - 17:00 Gasoline Engine Overhauls & MRO +1.251.990.5080 08:00 - 17:00 Technical Support (AvGas & For Textron Lycoming must take the position that in the case of a sudden 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. 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.
