                This  AD   2017-16-11   requires an inspection of connecting rods and replacement of affected connecting rod small end bushings.  AD was prompted by several reports of connecting rod failures resulting in uncontained engine failure and in-flight shutdowns (IFSDs).   AD applies to:            (1) All Lycoming Engines reciprocating engines listed in Table 1 of Lycoming Engines MSB No. 632B, dated August 4, 2017, and (2) all Lycoming Engines reciprocating engines that were overhauled or repaired using any replacement part listed in Table 2 of Lycoming MSB No. 632B, which was shipped from Lycoming Engines during the dates listed in Table 2 of Lycoming  MSB No. 632B.                Reason of this AD is reports of uncontained engine failures and IFSDs due to failed connecting rods on various models o...

PIPER PA28   LYCOMING  360 FAMILY            22/08/2015                 Engine failure.            At 2 mins and 15 seconds (2nm north of the airfield and at approx. 1,250 ft) a massive bang was heard coming from the engine, instant power loss and Engine T&P’s went into the red and dropped straight down to no reading. Pilot declared a Mayday emergency (Engine Failure) still on Seething radio frequency (122.60), with the intention of returning to the airfield for an attempted force landing. Seething Air ground radio confirmed that runway 24 could be used and the Fire & Rescue team were on standby at the Alpha hold to follow us down the runway.         At around 1nm to the airfield and attempting to keep high and fast rather than low and slow the aircraft was still at around 800ft so continuous slide slipping and position changes were used, flaps wer...

Subject : Specified Fuels for Spark Ignited Gasoline Aircraft Engine  Lycoming engine released SI-1070S dated 24 April 2013, which approved a wide varity of engine for use with ASTM D7547 UL91 unleaded avgas.                          Engine models added through this approval include the large installed base of: O-235-K, L, M, N, P; O-320-B, D; IO-320-B, D; AEIO-320-A, B, C; LIO- 320-B; HO-360-C; HIO-360-B, G; O-540-A, E, F, G, H, J; and IO-540-C, D, N, T, V, W, AB, AF engine models.            European Aviation Safety Administration (EASA) Safety Information Bulletin (SIB) 2011-01 provided aircraft-level approval on the basis of engine approval.

  Service Instruction No. 1553 DATE: March 26, 2013 SUBJECT:                       Additional Cylinder Fin Stabilizer MODELS AFFECTED: IO540 E1B5        TIO540A2B,A2C,J2B,J2BD,F2BD,S1ADL                                          TIO540J2B,J2BD, F2BD                As a precaution to prevent cracks from forming in the intake wall between the cylinder fins No. 1 thru 15  Lycoming Engines recommends that an additional fin stabilizer P/N 75164 be installed on cylinder P/N LW12966 on the affected Lycoming engine models identified in SI.           To install the new stabilizer P/N 75164 on the cylinder fins: 1. If the engine is installed, remove the exhaust system and intercylinder baffles (in accordance with  the applicable inst...

            Along with tightening the filter goes proper safety wiring. Some argue that you shouldn't safety the filter until after doing the run-up and leak check. Others believe that waiting till after the leak check is an open invitation to forget to safety the filter.            Either way, you've got to safety it with safety wire, and personal experience favors doing it before the leak check. Unless you've got the natural gift of being a great safety "wirer," chances are you'll be making some of the most common safety-wiring mistakes. Some you can cover-up quite easily and effectively. Others require starting over.           Just remember that a little practice will prevent problems in the future. For example, on the Champion filters with the safety wire holes at the top, the safety wire has a nasty habit of getting onto the rim of the filter can.             T...

                    Both manufacturers Lycoming and Continental agree that inactivity in excess of 30 days strongly suggests the need for some special preservation methods and chemicals, especially if the aircraft is located near salt water or similar humid environment. Lycoming Service Letter SL180 Engine Preservation for Active and Stored Aircraft Lycoming's procedure is as follows:          Install a preservative by one of the following methods: Drain the lubricating oil from the sump or system and replace with a preservative oil mixture. This preservation mixture consists of one part by volume MIL-C-6529C Type I concentrated preservative compound added to three parts by volume of MIL-L-6082C (SAE J1966), Grade 1100, mineral aircraft engine oil or oil conforming to MIL-C-6529C Type II. Follow carefully the manufacturer's instructions before use.          An alternative...

                        It is important to remember that long-term preservation of engines can result in trapping large amounts of oil in the combustion chambers of one or more cylinders. For this reason, engines should not be rotated until all of the preservative oil is drained away. Failure to do so can result in damage to the piston, connecting rod, and crankshaft of the flooded cylinder.                           To return the aircraft to service, remove seals, tape, and desiccant bags. Use a solvent to remove tape residue. Remove spark plugs or dehydrator plugs.  With the magnetos off, rotate the propeller by hand through sufficient rotations to remove excess preservative oil from the cylinders. Drain the remaining preservative through the sump.                    Most engines are equipped with a qui...

                  Note the factory is quoted verbatim here per Lycoming SL 180B: "Pulling engines through by hand when the aircraft is not run or flown for a week or so is not recommended. Pulling the engine through by hand prior to start or to minimize rust and corrosion does more harm than good. The cylinder walls, piston, rings, cam and cam followers only receive splash and vapor lubrication. When the prop is pulled through by hand, the rings wipe oil from cylinder walls."                   "The cam load created by the valve train wipes oil off the cam and followers. After two or three times of pulling the engine through by hand without engine starts, the cylinders, cam and followers are left without a proper oil film. Starting engines without proper lubrication can cause scuffing and scoring of parts resulting in excessive wear."                ...

      The ECi P/N AEL14995 pushrod shroud spring retainers are a parts manufacturer approval (PMA)  replacement for the Lycoming Engines P/N LW-14995 “Shroud Tube Retaining Springs.” FAA has received reports that several of the ECi pushrod shroud  spring retainers, P/N AEL14995, have failed. The failure of the spring retainer can cause the push rod  tube or shroud to become loose and possibly leak oil. ECi has redesigned the P/N AEL14995 pushrod  shroud spring retainers, and the FAA recommends the earlier design made from heat treated carbon  steel be removed from service. Recommendations by FAA              ECi Service Instruction, SI No.12-1, dated October 29, 2012, shows how to identify the older  designed pushrod shroud spring retainers. If your parallel valve Lycoming Engines 320, 360, or 540  series engine was overhauled using an ECi overhaul gasket set that included the AEL14995 pushrod...
