## Abstract

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. The AD applies to all Sikorsky Model S-70, S-70A, and S-70C helicopters, which are restricted category helicopters derived from the military Model UH-60 helicopter. The part number (P/N) for the No. 2 crossfeed breakaway valve listed in the "Required Actions" section is incorrect. This document corrects that error. Also, this document contains a response to a comment received after publication of the Final Rule. In all other respects, the original document remains the same.
