Airworthiness Directives; Textron Lycoming Division, AVCO Corporation Fuel Injected Reciprocating Engines.

Résumé

This amendment supersedes two existing airworthiness directives (AD's), that are applicable to certain Textron Lycoming fuel injected reciprocating engines. These AD's currently require inspection, and replacement if necessary, of externally mounted fuel injector fuel lines. These amendments require adding engine series to the applicability that have been identified with the potential for the same problem and necessitate being included in the list of Textron Lycoming fuel injected reciprocating engine series. This amendment is prompted by the need to ensure that the additional Textron Lycoming fuel injected engine series listed in this final rule receive the same inspections as series covered by the current AD's. The actions specified by this AD are intended to prevent failure of the fuel injector fuel lines allowing fuel to spray into the engine compartment, resulting in an engine fire.
