2012-28427 Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model Helicopters Rule We are adopting a new airworthiness directive (AD) for Sikorsky Model S-70, S-70A, and S-70C helicopters, which are restricted category helicopters derived from the military Model UH-60 helicopter. This AD would require reducing or establishing life limits for certain listed helicopter parts. This AD is prompted by a review of the United States Army's analysis of their Model UH-60 fleet, which determined it necessary to establish or reduce the life limits of certain parts. The actions are intended to prevent fatigue failure of a part and subsequent loss of control of the helicopter. 2012-11-29 2012 11 https://www.federalregister.gov/documents/2012/11/29/2012-28427/airworthiness-directives-sikorsky-aircraft-corporation-sikorsky-model-helicopters https://www.govinfo.gov/content/pkg/FR-2012-11-29/pdf/2012-28427.pdf Transportation Department; Federal Aviation Administration 492,159 We are adopting a new airworthiness directive (AD) for Sikorsky Model S-70, S-70A, and S-70C helicopters, which are restricted category helicopters derived from the military Model UH-60 helicopter.
