Helicopter Air Ambulance, Commercial Helicopter, and Part 91 Helicopter Operations
Document Number: 2014-03689
Type: Rule
Date: 2014-02-21
Agency: Federal Aviation Administration, Department of Transportation
This final rule addresses helicopter air ambulance, commercial helicopter, and general aviation helicopter operations. To address an increase in fatal helicopter air ambulance accidents, the FAA is implementing new operational procedures and additional equipment requirements for helicopter air ambulance operations. This final rule also increases safety for commercial helicopter operations by revising requirements for equipment, pilot testing, and alternate airports. It increases weather minimums for all general aviation helicopter operations. Many of these requirements address National Transportation Safety Board safety recommendations, and are already found in FAA guidance. Today's changes are intended to provide certificate holders and pilots with additional tools and procedures that will aid in preventing accidents.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
Document Number: 2014-03673
Type: Proposed Rule
Date: 2014-02-21
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede airworthiness directive (AD) 2007-10- 07, which applies to all Turbomeca S.A. Arriel 2B, 2B1, and 2B1A turboshaft engines. AD 2007-10-07 currently requires an inspection of the splines of the coupling assembly and the hydro-mechanical metering unit (HMU) drive gear shaft for wear. This proposed AD would require the same inspection and expand the affected population. This proposed AD would also remove Arriel 2B1A engines from the applicability. We are proposing this AD to prevent failure of the HMU drive gear shaft, which could lead to damage to the engine and damage to the airplane.
