AD 2020-18-19 Retains the Requirements of AD 2014-12-07...

The FAA is superseding Airworthiness Directive (AD) 2014-12-07 for Agusta S.p.A (Agusta) Model AB412 and AB412EP helicopters. AD 2014-12-07 requires inspecting the rotor brake pinion (pinion) for a crack and replacing it if there is a crack.

This AD retains the requirements of AD 2014-12-07 and also requires removing certain serial-numbered pinions from service. This AD was prompted by a report of an additional cracked pinion. The actions of this AD are intended to address an unsafe condition on these products. This AD becomes effective September 21, 2020.

Supplementary Information: This AD is a final rule that involves requirements affecting flight safety, and the FAA did not provide you with notice and an opportunity to provide your comments prior to it becoming effective. However, the FAA invites you to participate in this rulemaking by submitting written comments, data, or views. The most helpful comments reference a specific portion of the AD, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit them only one time. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will file in the docket all comments received, as well as a report summarizing each substantive public contact with FAA personnel concerning this rulemaking during the comment period. The FAA will consider all the comments received and may conduct additional rulemaking based on those comments.
