This proposed 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 hydro-mechanical metering unit (HMU). This proposed AD would require removing any pre-modification (mod) TU 158 HMU and replacing with a part eligible for installation. We are proposing this AD to prevent failure of the HMU, failure of the engine, IFSD, and loss of the helicopter.", "2016-11-04", 2016, 11, "https://www.federalregister.gov/documents/2016/11/04/2016-26335/airworthiness-directives-turbomeca-sa-turboshaft-engines", "https://www.govinfo.gov/content/pkg/FR-2016-11-04/pdf/2016-26335.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A.
