PRODUCT: Lycoming Engines model TIO-540-A
series reciprocating engines SUBJECT: Airworthiness Directive 71-13-01R1 ACTION: Final rule; rescission
SUMMARY: The existing AD, AD 71-13-01, was
prompted by a report of a failed fuel injector tube assembly. Since
AD 71-13-01 was issued, the FAA became aware that Lycoming Engines
no longer supports Service Bulletin (SB) No. 335A, which was
incorporated by reference in AD 71-13-01. The intent of the
requirements of that SB is now in Lycoming Engines Mandatory SB No.
342F, which has been incorporated by reference into AD 2008-14-07.
The FAA determined, therefore, that this requirement is duplicated
by another AD.
