Airworthiness Directive 2009-02-03
recurringAirworthiness Directives; Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO Series Reciprocating Engines, Teledyne Continental Motors (TCM) LTSIO-360-RB and TSIO-360-RB Reciprocating Engines, and Superior Air Parts, Inc.

What this AD requires
The FAA is superseding an existing airworthiness directive (AD) for 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. That AD currently requires inspecting servo plugs for looseness and damage on fuel injection servos that have a servo plug gasket, part number (P/N) 365533, installed, and if loose, inspecting the servo regulator cover threads for damage, inspecting the gasket for damage, reinstalling acceptable parts, and torquing the servo plug to a new, higher torque to maintain the proper clamp-up force between the plug and cover. This AD requires the same inspections, except if the plug is found loose, servo plug gasket, P/N 365533, must be replaced with a new, improved gasket, P/N 2577258. This AD also requires replacement by December 31, 2009, of servo plug gaskets, P/N 365533, manufactured and made available on or after August 22, 2006, as mandatory terminating action to the repetitive inspections required by this AD. This AD also prohibits the installation of any servo plug gasket, P/N 365533. This AD also clarifies the TCM engine model applicability, and adds Bendix RSA-5 and RSA-10 series fuel injection servos to the applicability. This AD results from Precision Airmotive LLC introducing the installation of a new improved servo plug gasket, P/N 2577258, to the affected Precision Airmotive LLC RSA-5 and RSA-10 series, and Bendix RSA-5 and RSA-10 series, fuel injection servos. 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 2009-02-03 applies to
Applies to Lycoming IO/(L)IO/TIO/(L)TIO/AEIO/AIO/IGO/IVO/HIO series, Teledyne Continental Motors LTSIO-360-RB and TSIO-360-RB, and Superior Air Parts IO-360 series reciprocating engines fitted with a Precision Airmotive LLC or Bendix RSA-5 or RSA-10 series fuel injection servo having servo plug gasket P/N 365533 installed under fuel injection servo plug P/N 383493 on or after August 22, 2006; also applies to any such servo received for installation on or after that date without a P/N 2577258 gasket and without a letter 'G' on the servo plug, or with unknown installation history.
Whether AD 2009-02-03 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.
