Airworthiness Directives; The Boeing Company Model 767 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model 767 airplanes. This proposed AD would require repetitive inspections to detect fatigue cracking in the upper wing skin at the fastener holes common to the inboard and outboard front spar pitch load fittings, and corrective actions if necessary. This proposed AD results from reports of cracking in the upper wing skin at the fastener holes common to the inboard and outboard front spar pitch load fittings. We are proposing this AD to detect and correct fatigue cracking in the upper wing skin at the fastener holes common to the inboard and outboard front spar pitch load fittings, which could result in the loss of the strut-to-wing upper link load path and possible separation of a strut and engine from the airplane during flight.
Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes, and A340-200, -300, -500 and -600 Series Airplanes
We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. This 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: Several cases of corrosion and damage on the Down Drive Shafts (DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box (IPGB), on all 10 Flap Tracks (5 per wing), have been reported by AIRBUS Long Range Operators. Investigations have revealed that corrosion and wear due to absence of grease in the spline interfaces could cause [DDS] disconnection which could result in a free movable flap surface, potentially leading to aircraft asymmetry or even flap detachment.
Proposed Amendment of Class E Airspace; Austin, TX
This action proposes to amend Class E airspace in the Austin, TX area. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Austin Executive Airport, Austin, TX. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Removal of Class E Airspace, Brunswick, ME; and Establishment of Class E Airspace, Wiscasset, ME
This action proposes to remove Class E airspace at Brunswick, ME, as the airport has closed and the associated Standard Instrument Approach Procedures (SIAPs) removed, and to establish Class E airspace at Wiscasset, ME, to accommodate the SIAPs developed for the airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at Wiscasset Airport, Wiscasset, ME.
Airworthiness Directives; Various Aircraft Equipped With Honeywell Primus II RNZ-850( )/-851( ) Integrated Navigation Units
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Honeywell Primus II RNZ-850( )/-851( ) integrated navigation units (INUs). As one alternative for compliance, the existing AD provides for a one-time inspection to determine whether a certain modification has been installed on the Honeywell Primus II NV-850 navigation receiver module (NRM), which is part of the INU. In lieu of accomplishing this inspection, and for aircraft found to have an affected NRM, that AD provides for revising the aircraft flight manual to include new limitations for instrument landing system approaches. That AD also requires an inspection to determine whether certain other modifications have been done on the NRM; and doing related investigative, corrective, and other specified actions, as
Airworthiness Directives; Rolls-Royce plc RB211-Trent 500, 700, and 800 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product, and results from the risk of engine fuel-to-oil heat exchanger (FOHE) blockage. The MCAI describes the unsafe condition as:
Airworthiness Directives; The Boeing Company Model 757 Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 757 airplanes. This AD requires inspecting to verify the part number of the low-pressure flex-hoses of the flightcrew and supernumerary oxygen system installed under the oxygen mask stowage box at a flightcrew and supernumerary oxygen mask location, and replacing with a new non-conductive low-pressure flex-hose of the oxygen system if necessary. This AD results from reports of a low-pressure flex-hose of a flightcrew oxygen system that burned through due to inadvertent electrical current from a short circuit in an adjacent audio select panel. We are issuing this AD to prevent inadvertent electrical current, which can cause the low-pressure flex-hose of a flightcrew or supernumerary oxygen system to melt or burn, resulting in oxygen system leakage and smoke or fire.
Airworthiness Directives; The Boeing Company Model 767-200, -300, and -300F Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 767-200, -300, and -300F series airplanes. For certain airplanes, this AD requires installing support hardware and modifying the interfacing wiring of the fuel quantity indicating system (FQIS) densitometer. For certain other airplanes, this AD requires replacing the existing hot short protector (HSP) on the FQIS densitometer with a new HSP. This AD also requires revising the Airworthiness Limitations (AWL) section of the Instructions for Continued Airworthiness to incorporate AWL No. 28-AWL-22. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the center tank fuel densitometer from overheating and becoming a potential ignition source inside the center fuel tank, which, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.
