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 shroud spring retainer, review ECi SI 12-1, “AEL14995 Pushrod Shroud Spring Retainer (Clip).”
Although this airworthiness concern does not warrant mandatory action, if the old design pushrod shroud spring retainers are identified, the FAA recommends replacing the old design pushrod shroud spring retainers with new spring retainers. If the retainer spring is found to be broken or cracked, replace it with an approved part as required by 14 CFR Section 91.405(a).
Pushrod Shroud Spring Retainers, Engine Components Part No. AEL14995, for Lycoming Engines 320, 360, and 540 Series Engines
