| 2017-04634 | Airworthiness Directives; Safran Helicopter Engines, S.A. Turboshaft Engines | Rule | We are adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. Arriel 2B turboshaft engines. This AD requires removing any pre-modification (mod) TU 158 hydro-mechanical metering unit (HMU) and replacing with a part eligible for installation. This AD was prompted by a report of an uncommanded in- flight shutdown (IFSD) on a single-engine helicopter, caused by a low returning spring rate of the needle of the HMU. We are issuing this AD to correct the unsafe condition on these products. | 2017-03-09 | 2017 | 3 | https://www.federalregister.gov/documents/2017/03/09/2017-04634/airworthiness-directives-safran-helicopter-engines-sa-turboshaft-engines | https://www.govinfo.gov/content/pkg/FR-2017-03-09/pdf/2017-04634.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A.
