Federal Aviation Administration November 19, 2015 – Federal Register Recent Federal Regulation Documents

Aviation Maintenance Technician Schools
Document Number: 2015-29505
Type: Proposed Rule
Date: 2015-11-19
Agency: Federal Aviation Administration, Department of Transportation
This action extends the comment period for an NPRM published on October 2, 2015. In that document, the FAA proposes to amend the regulations governing the curriculum and operations of FAA-certificated Aviation Maintenance Technician Schools. These amendments would modernize and reorganize the required curriculum subjects in the appendices of the current regulations. They would also remove the course content items currently located in the appendices and require that they be placed in each school's operations specifications so they could more easily be amended when necessary. The amendments are needed because the existing curriculums are outdated, do not meet current industry needs, and can be changed only through notice and comment rulemaking. These amendments would ensure that aviation maintenance technician students receive up-to-date foundational training to meet the demanding and consistently changing needs of the aviation industry. This extension is a result of a joint request from Aviation Technical Education Council (ATEC), Aeronautical Repair Station Association (ARSA), Aircraft Owners and Pilots Association (AOPA), Airlines for America (A4A), Aviation Suppliers Association (ASA), Helicopter Association International (HAI), Modification And Replacement Parts Association (MARPA), National Air Carrier Association (NACA), National Air Transport Association (NATA), Regional Airline Association, STEM Education Coalition (STEM), and University Aviation Association (UAA) (collectively, the ``Petitioners'').
Airworthiness Directives; Airbus Airplanes
Document Number: 2015-29444
Type: Proposed Rule
Date: 2015-11-19
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This proposed AD was prompted by investigations that revealed that the cover seal of the brake dual distribution valve (BDDV) was damaged and did not ensure efficient sealing. This proposed AD would require modifying the BDDV having certain part numbers; modifying the drain hose of the BDDV; checking for the presence of water, ice, and hydraulic fluid; and re-identifying the BDDV; and related investigative and corrective actions if necessary. We are proposing this AD to prevent damage to the BDDV, which could lead to water ingestion in the BDDV and freezing of the BDDV in flight, possibly resulting in loss of braking system function after landing.
Airworthiness Directives; Airbus Airplanes
Document Number: 2015-29443
Type: Proposed Rule
Date: 2015-11-19
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 95-18-08, for all Airbus Model A300-600 series airplanes. AD 95-18-08 currently requires repetitive inspections to detect cracks in the bottom skin of the wing in the area of the cut out for the pylon rear attachment fitting, and repair if necessary. Since we issued AD 95-18-08, we received a report that updated fatigue and damage tolerance analyses and a fleet survey found that certain inspection thresholds and intervals must be reduced to allow more timely findings of cracking. This proposed AD would, for certain airplanes, reduce the compliance times for the inspections. We are proposing this AD to detect and correct such fatigue-related cracking, which could result in reduced structural integrity of the wing.
Airworthiness Directives; Airbus Airplanes

Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2015-03- 06, for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340- 200, A340-300, A340-500, and A340-600 series airplanes. AD 2015-03-06 currently requires repetitive inspections of the left-hand and right- hand wing main landing gear (MLG) rib 6 aft bearing lugs (forward and aft) to detect any cracks on the two lugs, and replacement if necessary. Since we issued AD 2015-03-06, we have received reports of additional cracking of the MLG rib 6 aft bearing lugs. This proposed AD would reduce certain compliance times. We are proposing this AD to detect and correct cracking of the MLG rib 6 aft bearing lugs, which could result in collapse of the MLG upon landing.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-29441
Type: Proposed Rule
Date: 2015-11-19
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by reports of water leakage from the potable water system due to improperly installed waterline couplings, and water leaking into the electronics equipment (EE) bays from above the floor in the main cabin, resulting in water on the equipment in the EE bays. This proposed AD would require replacing the potable waterline couplings above the forward and aft EE bays with new, improved couplings. This proposed AD would also require sealing the main cabin floor areas above the aft EE bay, installing drip shields and foam blocks, and rerouting the wire bundles near the drip shields above the equipment in the aft EE bay. We are proposing this AD to prevent a water leak from an improperly installed potable water system coupling, or main cabin water source, which could cause the equipment in the EE bays to become wet, resulting in an electrical short and potential loss of system functions essential for safe flight.
Airworthiness Directives; Airbus Helicopters (Formerly Eurocopter France) Helicopters
Document Number: 2015-29402
Type: Proposed Rule
Date: 2015-11-19
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model SA341G and SA342J helicopters. This proposed AD would require repetitive inspections of a certain part-numbered main rotor hub torsion bar (torsion bar). This proposed AD is prompted by several cases of corrosion in the metal strands of the torsion bar. The proposed actions are intended to detect corrosion and prevent failure of the torsion bar, loss of a main rotor blade, and subsequent loss of control of the helicopter.
