## Abstract

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Leonardo S.p.A. (Leonardo) Model AB139, AW139, AW169, and AW189 helicopters. As published, one service bulletin reference in the AD is incorrect. This document corrects that error. In all other respects, the original document remains the same.
