The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to all Piper Aircraft, Inc. Models PA-31, PA-31-325, and PA-31-350 airplanes. Table 1 of paragraph (g) lists the incorrect model/part number for the Model PA-31-350, tail pipe assembly, top. This document corrects that error. In all other respects, the original document remains the same.

A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract

We are superseding an existing airworthiness directive (AD) for all Piper Aircraft, Inc. Models PA-31, PA-31-325, and PA-31-350 airplanes. That AD currently requires a detailed repetitive inspection of the exhaust system downstream of the turbochargers and repair or replacement of parts as necessary. This new AD requires visual repetitive inspections, expanding the inspection scope to include the entirety of each airplane exhaust system. This AD was prompted by reports of exhaust system failures upstream of aircraft turbochargers and between recurring detailed inspections. We are issuing this AD to correct the unsafe condition on these products.
