This action makes a correction to Airworthiness Directive (AD) 96-12-12, which was published in the Federal Register on June 6, 1996 (61 FR 28733), and concerns The New Piper Aircraft, Inc. Models PA31, PA31-300, PA31-325, and PA31-350 airplanes. That publication incorrectly references the date for the instructions to Piper Kit 763- 917 as ``revised June 18, 1980'' instead of ``revised June 18, 1990.'' The AD currently requires repetitively inspecting the upper section of the Fuselage Station (FS) 317.75 bulkhead for cracks, and incorporating one of two reinforcement kits depending on whether cracks are found in the FS 317.75 bulkhead area. This action corrects the AD to reflect the correct date of the instructions to Piper Kit 763-917.
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
This amendment supersedes Airworthiness Directive (AD) 80-22- 04, which currently requires the following on The New Piper Aircraft, Inc. (Piper) Models PA31, PA31-300, PA31-325, and PA31-350 airplanes: repetitively inspecting the upper section of Fuselage Station (FS) 317.75 bulkhead for cracks, and incorporating a certain reinforcement kit if any crack is found. This action requires inspecting (one-time) the upper section of the FS 317.75 bulkhead for cracks, and incorporating one of two reinforcement kits depending on whether cracks are found in the FS 317.75 bulkhead area. Cracks found on airplanes in compliance with the inspection requirements of AD 80-22-04 and the Federal Aviation Administration's policy on aging commuter-class aircraft prompted this action. The actions specified in this AD are intended to prevent structural failure of the vertical fin forward spar caused by cracks in the FS 317.75 bulkhead, which, if not detected and corrected, could result in loss of control of the airplane.
