Airworthiness Directives; Dassault Model Falcon 2000, Falcon 2000EX, Mystere-Falcon 900, Falcon 900EX, Fan Jet Falcon, Mystere-Falcon 50, Mystere-Falcon 20, Mystere-Falcon 200, and Falcon 10 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Dassault Model Falcon 2000, Mystere- Falcon 900, Falcon 900EX, Fan Jet Falcon, Mystere-Falcon 50, Mystere- Falcon 20, Mystere-Falcon 200, and Falcon 10 series airplanes. The existing AD currently requires repetitive tests and inspections to detect discrepancies of the overwing emergency exit, and corrective action if necessary. This proposed AD would expand the applicability of the existing AD and extend the repetitive test and inspection interval for all airplanes. This proposed AD results from reports of incorrect operation of the overwing emergency exit due to interference between the emergency exit and the interior accommodation. We are proposing this AD to prevent failure of the overwing emergency exits to open, and consequent injury to passengers or crew members during an emergency evacuation.
Airworthiness Directives; Fokker Model F28 Mark 0070 and 0100 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 747-200B, 747-200C, 747-200F, 747-300, 747-400, and 747SP series airplanes. The existing AD currently requires doing a detailed inspection of the left and right longeron extension fittings, and corrective action if necessary. This proposed AD would add airplanes to the applicability of the existing AD. This proposed AD results from reports that accidental drilling damage to the longeron extension fittings was found on airplanes not subject to the existing AD. We are proposing this AD to detect and correct accidental drilling damage of the longeron extension fittings, which could lead to cracking of the longeron extension fittings and result in rapid decompression of the airplane.
Airworthiness Directives; Airbus Model A310 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This proposed AD would require revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new and revised structural inspections and inspection intervals. This proposed AD results from issuance of new and revised structural inspections and inspection intervals. We are proposing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Boeing Model 747-200C and -200F Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-200C and -200F series airplanes. This proposed AD would require, among other actions, installing mounting brackets, support angles, and moisture curtains in the main equipment center. This proposed AD results from reports of water contamination in the electrical/electronic units in the main equipment center. We are proposing this AD to prevent water contamination of the electrical/ electronic units, which could cause the electrical/electronic units to malfunction, and as a consequence, could adversely affect the airplane's continued safe flight.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER, -135KE, -135KL, and -135LR Airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Boeing Model 747-400 and -400D Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 and -400D series airplanes. This proposed AD would require installing new relays to allow the flightcrew to turn off electrical power to the in-flight entertainment (IFE) system and other non-essential passenger cabin systems through the left and right utility bus switches, and other specified actions. This proposed AD results from an IFE systems review. We are proposing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE system and other non-essential passenger cabin systems through utility bus switches in the flight compartment, in the event of smoke or fumes. The flightcrew's inability to turn off electrical power to the IFE system and other non-essential passenger cabin systems could result in the inability to control smoke or fumes in the airplane flight deck or passenger cabin during a non-normal or emergency situation.
Airworthiness Directives; Airbus Model A330 and A340 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and Model A340-541 and A340- 642 airplanes. The original NPRM would have superseded an existing AD that currently requires operators to revise the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new information. This information includes, for all affected airplanes, decreased life limit values for certain components; and for Model A330-200 and -300 series airplanes, new inspections, compliance times, and new repetitive intervals to detect fatigue cracking, accidental damage, or corrosion in certain structures. The original NPRM proposed to revise the ALS, for all affected airplanes, by adding new Airworthiness Limitations Items (ALIs) to incorporate service life limits for certain items and inspections to detect fatigue cracking, accidental damage or corrosion in certain structures, in accordance with the revised ALS of the ICA. The original NPRM resulted from the issuance of new and more restrictive service life limits and structural inspections based on fatigue testing and in-service findings. This new action revises the original NPRM by adding airplanes, adding new requirements, and including more restrictive compliance thresholds and intervals. We are proposing this supplemental NPRM to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements, and to prevent failure of certain life-limited parts, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus A330-200 and -300 Series Airplanes and Model A340-200 and -300 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This proposed AD would require, among other actions, modifying the door- mounted escape system of the forward right side door slide compartment. This proposed AD results from reports indicating that the forward right escape slide inflated 90 degrees out of alignment after deployment from the forward right side slide compartment. We are proposing this AD to prevent the escape slide from being unusable during an emergency evacuation and consequent injury to passengers or crewmembers.
Airworthiness Directives; Airbus Model A310 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require repetitive detailed and high-frequency eddy current inspections for cracking around the heads of the fasteners on the forward fastener row of certain areas of the station (STA) 259.5 circumferential butt splice, and repair if necessary. This proposed AD would also require a preventive modification, which would eliminate the need for the repetitive inspections. This proposed AD results from a report that an operator found multiple cracks in the fuselage skin of a Model 737-200 airplane, at the forward fastener row of the STA 259.5 circumferential butt splice between stringers 19 and 24. We are proposing this AD to prevent cracking of the STA 259.5 circumferential butt splice, which could result in loss of structural integrity of the fuselage skin and possible loss of cabin pressure.
Airworthiness Directives; Boeing Model 757-200, -200CB, and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200, -200CB, and -300 series airplanes. This proposed AD would require repetitive inspections for cracks of the intercostal tee clips and attachment fasteners at the number 3 and number 4 doorstops of the passenger door cutouts, or repetitive inspections for cracks of the intercostal tee clips; and related investigative/ corrective actions if necessary. This proposed AD also provides an optional terminating action for the repetitive inspections. This proposed AD results from reports of cracked intercostal tee clips at the number 3 and number 4 doorstops of the passenger door cutouts. We are proposing this AD to detect and correct cracking of the tee clips, which could result in additional stress on the adjacent tee clips, surrounding intercostals, edge frame, door structure and doorstops. This additional stress could cause further cracking or breaking of the tee clips, which could result in failure of the door to seal and consequent rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 747-400, -400D, and -400F Series Airplanes; Boeing Model 757 Airplanes; and Boeing Model 767 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing airplanes listed above. This proposed AD would require an inspection of certain lighted pushbutton switches in the flight compartment for configuration `D' master modules and part numbers and corrective action if necessary. This proposed AD also provides an option to inspect panel assemblies for part numbers. This proposed AD results from a report indicating that the integrated drive generator failed in flight due to a possible switch malfunction. We are proposing this AD to ensure that certain lighted pushbutton switches in the flight compartment do not malfunction and cause the flightcrew to be unable to control critical airplane systems and continue safe airplane operation.
Airworthiness Directives; Airbus Model A300 Series Airplanes and Airbus Model A300-600 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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. The MCAI describes the unsafe condition as:
Airworthiness Directives; Boeing Model 767-300F Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-300F series airplanes. This proposed AD would require replacing the rotomolded duct(s) of the mix manifold system with new duct(s). This proposed AD results from a report of failures of the duct joint seal of the mix manifold system. We are proposing this AD to prevent air conditioning leakage into the mix manifold bay. Such leakage could decrease the air flow to the flight compartment and main cabin or could allow smoke into the flight compartment in the event of a fire in the main cabin or forward cargo compartment.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA is revising an earlier supplemental NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A318, A319, A320, and A321 airplanes. The first supplemental NPRM would have superseded an existing AD that currently requires repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. These actions resulted from reports of wear damage to the inboard flap trunnions after incorporation of the terminating modification, and certain airplanes were inadvertently excluded from the applicability in the original NPRM. This new action revises the first supplemental NPRM by adding airplanes that were recently added to the type certificate data sheet. We are proposing this second supplemental NPRM to detect and correct wear of the inboard flap trunnions, which could lead to loss of flap surface control and consequently result in the flap detaching from the airplane. A detached flap could result in damage to the tail of the airplane.
