Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
Document Number: 2012-8064
Type: Proposed Rule
Date: 2012-04-04
Agency: Federal Aviation Administration, Department of Transportation
We are proposing a new airworthiness directive (AD) for all Eurocopter Deutschland GmbH (ECD) MBB-BK 117 A-3, MBB-BK 117 A-4, MBB- BK B-1, MBB-BK 117 B-2, and MBB-BK C-1 helicopters equipped with a certain external-hoist system (hoist system) by requiring either deactivating the entire hoist system or deactivating the hoist system cable cutter function on the hoist system operator control handle (operator handle). This AD was prompted by an uncommanded activation of the hoist cable cutter function on an MBB-BK117 C-1 helicopter. This AD is intended to prevent uncommanded cutting of the hoist cable and subsequent injury to persons being lifted by the hoist.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2012-8056
Type: Proposed Rule
Date: 2012-04-04
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Eurocopter France (EC) Model SA-365N, SA-365N1, SA-366G1, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted by the discovery of a cracked main rotor mast nut. This condition, if not corrected, could lead to complete failure of the mast nut, resulting in failure of the rotor mast and loss of control of the helicopter. This proposed AD would require replacing the main rotor mast nut with an airworthy main rotor mast nut. We are proposing this AD to prevent failure of the main rotor mast and subsequent loss of control of the helicopter.
