Applicability: Textron Lycoming reciprocating opposed piston engines incorporating fuel injection lines as listed in Textron Lycoming Service Bulletin No. (SB) 342A, dated May 29, 1992, except for Model TIO-540-S1AD engines. Affected engine models are installed on but not limited to Piper PA-24 Comanche, PA-30 and PA-39 Twin Comanche, PA-28 Arrow, and PA-23 Aztec; Beech 60 Duke and 23 Musketeer; Mooney M20; and Cessna 177 Cardinal aircraft. NOTE: Engines with an "I" in the prefix of the model designation incorporate fuel injection.
Compliance: Required as indicated, unless accomplished previously.
To prevent failure of the fuel injector fuel lines allowing fuel to spray into the engine compartment, resulting in an engine fire, accomplish the following:
(a) Within 25 hours time in service after the effective date of this AD, inspect the fuel injector fuel lines between the fuel manifold and the fuel injector nozzles in accordance with Textron Lycoming Service Bulletin No. 342A, dated May 26, 1992.
(b) Prior to further flight, replace any fuel injector fuel line that does not meet all the return to service conditions specified in Textron Lycoming SB No. 342A, dated May 26, 1992.
(c) Thereafter, at each annual inspection, at each 100-hour inspection, at each engine overhaul, and after any maintenance has been performed on the engine where the fuel injector fuel lines have been disconnected, moved, or loosened, reinspect the fuel injector fuel lines in accordance with Textron Lycoming SB No. 342A, dated May 26, 1992, and replace as necessary any fuel injector fuel line that does not meet all the return to service conditions specified in that SB.
(d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, New York Aircraft Certification Office. The request should beforwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, New York Aircraft Certification Office. NOTE: Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the New York Aircraft Certification Office.
(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.
(f) The inspection, and replacement, if necessary of the fuel injector fuel lines shall be done in accordance with the following service document:
