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.
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 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.
