## Summary

The FAA is correcting a Notice of Proposed Rulemaking (NPRM) that was published in the Federal Register. That NPRM proposed to issue an airworthiness directive (AD) that would apply to all Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. As published, the references to the incorporated material in paragraphs (h)(1) through (4), and paragraph (i) of the NPRM reference an incorrect mandatory continuing airworthiness information (MCAI) identifier. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is publishing the entire proposed rule in the Federal Register.
