Airworthiness Directive 2012-27051

What this AD requires
We are revising an existing airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. Model P-180 airplanes. That AD currently requires replacement of any firewall shutoff or crossfeed valve with a serial number in a certain range even if it has been previously modified. The way the applicability was written includes valves that should not be affected and are not included in the referenced service information. This AD requires the same actions as the current AD, but only affects those firewall shutoff valves referenced in the referenced service information. We are issuing this AD to clarify the affected parts required to correct the unsafe condition on these products.
Which aircraft AD 2012-27051 applies to
Applies to all serial numbers, but only to airplanes equipped with a firewall shutoff or crossfeed valve identified in the Effectivity table of Piaggio Aero Industries SB No. ASB80-0191, dated February 27, 2003. Valves previously modified per AD 2003-17-03 and re-identified with an 'A' suffix, and not listed in that Effectivity table, are not affected.
Whether AD 2012-27051 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.
