What the agency says
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to all MD Helicopters, LLC Model 369, 369A, 369D, 369E, 369F, 369FF, 369H, 369HE, 369HM, 369HS, 500N, and 600N helicopters. As published, the header of the regulatory text is missing the AD number and the amendment number. This document corrects those errors. In all other respects, the original document remains the same.
