What this AD requires
This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2008-06-51 that was sent previously to all known U.S. owners and operators of Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series reciprocating engines, TCM TSIO-360-RB reciprocating engines, and Superior Air Parts, Inc. IO-360 series reciprocating engines with certain Precision Airmotive LLC RSA-5 and RSA-10 series fuel injection servos. This AD results from eighteen reports of fuel injection servo plugs, part number (P/N) 383493, that had loosened or completely backed out of the threaded plug hole on the regulator cover of the fuel injection servo. These servo plugs were installed with servo plug gasket, P/N 365533, under the plug hex-head. We are issuing this AD to prevent a lean running engine, which could result in a substantial loss of engine power and subsequent loss of control of the airplane.
Which aircraft AD 2008-08-14 applies to
Applies to Lycoming IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series reciprocating engines (any displacement); Teledyne Continental Motors TSIO-360-RB engines; and Superior Air Parts IO-360 series engines - in each case only when fitted with an installed Precision Airmotive LLC RSA-5 or RSA-10 series fuel injection servo having servo plug gasket P/N 365533 under fuel injection servo plug P/N 383493, where the engine or servo was new, rebuilt, overhauled, or repaired since August 22, 2006. Also applies to any other Precision Airmotive fuel injection servo received since that date or that has had the P/N 383493 plug removed during maintenance since that date.
Whether AD 2008-08-14 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
