What this AD requires
This document makes a correction to AD 2010-13-07, which was published in the Federal Register on June 23, 2010 (75 FR 35619), and applies to certain Piper Aircraft, Inc. Models PA-32R-301T and PA-46- 350P airplanes. AD 2010-13-07 requires you to replace V-band exhaust couplings, part number (P/N) Lycoming 40D21162-340M or Eaton/Aeroquip 55677-340M with an improved design Eaton/Aeroquip P/N NH1009399-10 or Lycoming P/N 40D23255-340M. In the Summary and Discussion sections of the published AD, we incorrectly stated that the AD requires replacing any spot-welded, V-band exhaust coupling with a riveted, V-band exhaust coupling instead of stating the specific P/N to be replaced. Also, in the Cost of Compliance section, we incorrectly stated that Model PA- 32R-301T airplanes, instead of Model PA-46-350P airplanes, are equipped with two of the affected V-band clamps. We are issuing this document to help eliminate any confusion that this AD may have created.
Which aircraft AD 2010-18023 applies to
Whether AD 2010-18023 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.
