Airworthiness Directives; ATR-GIE Avions de Transport Régional
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This proposed AD was prompted by reports of fuel quantity indication malfunctions caused by fuel probe failure. This proposed AD would require identifying the part number and serial number of the fuel probes and replacing if necessary. We are proposing this AD to prevent fuel probe failure, which could lead to undetected fuel starvation and consequent dual engine in-flight flame-out.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by a report of loose bolts that are intended to secure the translating door crank assembly to the outside handle shaft. This proposed AD would require a detailed inspection for loose bolts on the aft translating door crank assembly, and removal and reinstallation of the bolts. We are proposing this AD to prevent loose bolts from falling out. If both bolts become loose or fall out after the door is closed and locked, the door cannot be opened from inside or outside, which could impede evacuation in the event of an emergency.
Petition for Exemption; Summary of Petition Received
This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes
We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD requires, for certain airplanes, retorquing and replacing the pylon outboard and inboard lower link fittings. For all airplanes, this AD requires repetitive retorquing of the pylon outboard and inboard lower link fittings. This AD was prompted by a report of a loose lower link assembly on the left and right pylons. We are issuing this AD to prevent loss of a shear pin on the pylon outboard and inboard lower link fittings, which could result in failure of the fitting and consequent separation of the engine from the wing.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Makila 2A and Makila 2A1 turboshaft engines. This AD requires initial and repetitive visual inspections, and replacement of the splines of the high-pressure (HP) fuel pump/metering valve and the module M01 drive gear, if necessary. This AD was prompted by the failure of two HP fuel pumps that resulted in engine in-flight shutdowns. We are issuing this AD to prevent failure of the HP fuel pump, which could lead to an in-flight shutdown, damage to the engine, and forced landing or accident.
Amendment of Air Traffic Service (ATS) Routes in the Vicinity of Nabb, IN
This action modifies four VOR Federal airways (V-44, V-47, V- 49, and V-51) in the vicinity of Nabb, IN. The Nabb, IN (ABB), VHF Omnidirectional Range (VOR)/Tactical Air Navigation (VORTAC) facility that provides navigation guidance for a portion of the airways listed was damaged beyond repair by a tornado in 2012.
Fuel Tank Vent Fire Protection
This action would amend certain airworthiness regulations for transport category airplanes to require fuel tank designs that prevent a fuel tank explosion caused by flame propagation through the fuel tank vents from external fires. This action would add a new requirement for fuel tank vent fire protection and would increase the time available for passenger evacuation and emergency response. This proposed amendment would apply to applications for new type certificates and certain applications for amended or supplemental type certificates. It would also require certain airplanes produced in the future and operated by air carriers to meet the new standards.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2008-14-17 for certain Airbus Model A330-200 and A340-300 series airplanes. AD 2008- 14-17 required a high frequency eddy current (HFEC) inspection, corrective actions if necessary, and modifications. This new AD requires the same actions as those required by AD 2008-14-17, but with a reduced compliance time. This AD was prompted by a determination from a fatigue and damage tolerance evaluation that the compliance time needs to be revised. We are issuing this AD to detect and correct damage of the upper shell structure at the skin and frame interface, which could result in reduced structural integrity of the airframe.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2006-26-06 for certain The Boeing Company Model 777-200 and -300 series airplanes equipped with Rolls-Royce engines. AD 2006-26-06 required repetitive inspections to detect cracks of the outer V-blades of the thrust reverser, and corrective action if necessary. AD 2006-26-06 also provided for an optional terminating action for the repetitive inspections. This new AD adds, for airplanes on which the optional terminating action is done, repetitive inspections for cracking in the outer V-blade fittings of the hinge beam and latch beam ends of each thrust reverser half, and replacement of an affected thrust reverser half if necessary. This new AD also adds airplanes to the applicability. This AD was prompted by reports of cracked outer V- blade fittings at the hinge beam end of Rolls-Royce engine thrust reversers, on airplanes on which the optional terminating action was done. We are issuing this AD to prevent separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, which could result in unexpected thrust asymmetry and a possible runway excursion.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of failure of the high pressure shutoff valves (HPSOVs) causing the timer and monitor unit (TMU) to become inoperative since the HPSOV and the TMU are on the same circuit breaker. This AD requires a wiring modification to segregate the HPSOV power supply from the TMU. We are issuing this AD to prevent an inoperative TMU, which could result in the loss of the automatic de-icing mode, and lead to an increased workload for the flight crew and loss of control of the airplane.
