Federal Aviation Administration February 17, 2017 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Airplanes
Document Number: 2017-03019
Type: Proposed Rule
Date: 2017-02-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require inspecting the forward passenger doors to identify the part number, and for affected doors, inspecting to identify existing repairs and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters
Document Number: 2017-02863
Type: Proposed Rule
Date: 2017-02-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. This proposed AD would require adding an identification number to life- limited rod ends that do not have a serial number (S/N). The proposed actions are intended to address an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
Document Number: 2017-02859
Type: Proposed Rule
Date: 2017-02-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 (including configuration C-2e) and MBB-BK 117 D-2 helicopters. This proposed AD would require replacing the main rotor (M/R) blade vibration absorbers. This proposed AD is prompted by a report of strong M/R blade vibrations on a Model MBB-BK 117 C-2 helicopter. The proposed actions are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Romtex Anjou Aeronautique (Romtex) Torso Restraint Systems
Document Number: 2017-02858
Type: Proposed Rule
Date: 2017-02-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Romtex torso restraint systems (restraint systems) installed on but not limited to Airbus Helicopters Model AS350B2, AS350B3, EC130B4, EC130T2, and AS355NP helicopters. This proposed AD would require replacing certain restraint system buckles. This proposed AD is prompted by a report of several restraint system buckle knobs breaking. The proposed actions are intended to correct an unsafe condition on these products.
Airworthiness Directives; British Aerospace Regional Aircraft Airplanes
Document Number: 2017-02771
Type: Proposed Rule
Date: 2017-02-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model HP 137 Jetstream MK1, Jetstream Series 200, and Jetstream Series 3101 airplanes that would supersede AD 2014-07-07. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the forward main landing gear yoke pintle resulting from corrosion pits leading to stress corrosion cracking. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
