Airworthiness Directive 2010-13-07
one-timeAirworthiness Directives; Piper Aircraft, Inc. Models PA-32R-301T and PA-46-350P Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-32R-301T and PA-46-350P airplanes. This AD requires you to replace any spot-welded, V-band exhaust coupling with a riveted, V-band exhaust coupling. This AD results from reports that spot-welded, V-band exhaust couplings are failing. We are issuing this AD to prevent failure of the V-band exhaust coupling, which could cause the exhaust pipe to detach from the turbocharger. This failure could result in release of high-temperature gases inside the engine compartment and possibly cause an in-flight fire. An in-flight fire could lead to loss of control.
Which aircraft AD 2010-13-07 applies to
Serial ranges are model-specific: PA-32R-301T serial numbers 3257001 through 3257311; PA-46-350P serial numbers 4622001 through 4622200 and 4636001 through 4636341.
Whether AD 2010-13-07 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.
