Airworthiness Directives; Airbus Helicopters Deutschland GmbH
Document Number: 2016-27765
Type: Proposed Rule
Date: 2016-11-21
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) MBB-BK 117 D-2 helicopters. This proposed AD would require repetitively inspecting the bushings of the inner and outer forward trusses of both engines. This proposed AD is prompted by reports of delaminated and worn engine mount bushings. The proposed actions are intended to detect delaminated engine mount bushings, which can lead to excessive vibration, cracking, failure of the engine mount front support pins, and loss of helicopter control.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2016-27309
Type: Proposed Rule
Date: 2016-11-21
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model G-1159B airplanes. This proposed AD was prompted by a review of airplane maintenance records, which revealed that incorrect rudder assemblies were installed on certain airplanes. This proposed AD would require certain inspections, and replacement or modification of the rudder assembly if necessary. We are proposing this AD to address the unsafe condition on these products.
