AD: Lycoming Engines Reciprocating Engines

AD NUMBER: 2015-02-07

PRODUCT: Certain serial number (S/N) Lycoming Engines reciprocating engines.

ACTION: Final Rule

SUMMARY:  This AD was prompted by propeller governor shaft set screws coming loose due to improper installation.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain S/N Lycoming Engines reciprocating engines. The NPRM published in the Federal Register on September 11, 2014 (79 FR 54218).

The NPRM was prompted by events of propeller governor shaft set screws coming loose due to improper installation. If the set screws come loose, the engine may lose oil resulting in damage to the engine and damage to the airplane. The NPRM proposed to require application of Loctite 290, or equivalent, to the threads of the propeller governor shaft set screw at each installation of the set screw in addition to the peening of crankcase hole threads.

The FAA is issuing this AD to prevent the propeller governor shaft set screw from coming loose, causing damage to the engine and damage to the airplane.

DATES: This AD is effective March 11, 2015.

FMI: AD
