Summary
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Piper Aircraft, Inc. Model PA-31-350 airplanes. The wing locations of engine TIO-540-J2B and LTIO-540-J2B in table 1 of the Applicability, paragraph (c), section are incorrect. This document corrects that error. In all other respects, the original document remains the same; however we are publishing the entire rule in the Federal Register.
