Airworthiness Directive 2008-14-07
recurringAirworthiness Directives; Lycoming Engines, Fuel Injected Reciprocating Engines
What this AD requires
The FAA is superseding an existing airworthiness directive (AD) for certain fuel injected reciprocating engines manufactured by Lycoming Engines. That AD currently requires inspection, and replacement if necessary, of externally mounted fuel injector fuel lines. This AD requires the same actions but adds additional engine models and clarifies certain compliance time wording. This AD also exempts engines that have a Maintenance and Overhaul Manual with an Airworthiness Limitations Section that requires inspection and replacement, if necessary, of externally mounted fuel injector lines. This AD results from Lycoming Engines revising their Mandatory Service Bulletin to add new engine models requiring inspection, and from the need to clarify a repetitive inspection compliance time. We are issuing this AD to prevent failure of the fuel injector fuel lines that would allow fuel to spray into the engine compartment, resulting in an engine fire.
Which aircraft AD 2008-14-07 applies to
Applies to fuel-injected Lycoming reciprocating engines (model designations with an 'I' in the prefix) that have externally mounted fuel injection lines, per Table 1 of the AD covering families AEIO-320, AIO-320, IO-320, LIO-320, AEIO-360, AIO-360, HIO-360, IO-360, IVO-360, LIO-360, TIO-360, IGO-480, AEIO-540, IGO-540, and IO-540. Specific dash-suffix model designations are listed in Table 1, but the retrieved excerpt is truncated (cuts off mid-list within the IO-540 entries), so the full designation list is not reproduced here.
Whether AD 2008-14-07 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.
