2006-03-12: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires an inspection for chafing of certain wire bundles located above the center fuel tank, corrective actions if necessary, and replacement of wire bundle clamps with new clamps. This AD also requires an inspection for damage to the fuel vapor barrier area located below the wire bundles, and corrective action if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent chafed wire bundles near the center fuel tank, which could cause electrical arcing through the tank wall and ignition of fuel vapor in the fuel tank, and result in a fuel tank explosion.

2006-03-16: The FAA is adopting a new airworthiness directive (AD) for all Hamburger Flugzeugbau GmbH Model HFB 320 HANSA airplanes. This AD requires revising the Limitations section of the HFB 320 Hansa Airplane Flight Manual to prohibit operation of the airplane past its designed life limit for the primary structure, which is 15,000 flight hours or 15,000 fight cycles, whichever occurs first; and to require contacting the FAA for approval of analysis that the airplane is safe to continue operation beyond the designed life limit. This AD results from a report that all airplanes in operation might have met or exceeded the designed life limit for the primary structure. We are issuing this AD to prevent continued operation of an airplane beyond its designed life limit for the primary structure, which could result in reduced structural integrity of the airplane.

2006-03-07: The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires modifying the passenger door and installing new placards. This AD results from reports of the airstairs-type passenger door opening during flight. We are issuing this AD to prevent rapid decompression of the airplane, or ejection of a passenger or crew member out the door during flight.

2006-03-02: The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 and Falcon 2000EX airplanes. For all airplanes, this AD requires, among other actions, doing an inspection for damage of the feeder cables, and corrective actions if necessary; and installing a protective plate on the feeder cables. For certain airplanes, this AD also requires re-routing the wiring on the cockpit protector; drilling holes in the cockpit protector; and clamping the feeder cables; as applicable. This AD results from a drawing review and further associated inspections that highlighted a potential chafing risk between the third crew member's oxygen mask box and feeder cables routed in the area. We are issuing this AD to prevent chafing between the subject oxygen mask box and the adjacent feeder cables, which could generate smoke or fire in the cockpit that could be fanned by oxygen leakage from the oxygen mask box.

2006-02-02: The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD requires installing a rivet and washer in the hole of the upper frame of the auxiliary power unit (APU) firewall. This AD results from a report indicating that, during production, a pinhole was left open at the upper frame of the APU firewall. We are issuing this AD to ensure that the APU compartment is isolated from the rest of the airplane in the event of an APU fire.

2006-01-04: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Raytheon airplanes identified above. That AD currently requires a visual inspection to determine whether adequate clearance exists between the fan venturi motor casing and the adjacent equipment, and adjustments, if necessary; and a visual inspection to detect signs of overheating, degradation of insulating materials, and ingestion of debris into the motor, and replacement of discrepant parts with serviceable parts. This new AD instead requires that operators replace the fan venturi with a new or modified part. This AD results from reports that the fan venturi overheated and produced smoke while the airplane was on the ground. We are issuing this AD to prevent heat and fire damage to equipment adjacent to the fan venturi, which could result in smoke in the cabin and/or burning equipment.

2006-01-02: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas transport category airplanes, that requires an inspection of the upper lock link assembly of the nose landing gear (NLG) to determine the manufacturer, repetitive eddy current inspections for cracking, and modification or replacement if necessary. This AD also provides for optional terminating action for the repetitive inspections. The actions specified by this AD are intended to prevent fracture of the upper lock link assembly of the NLG, which could result in failure of the NLG to extend following a gear-down selection, and consequent gear-up landing, structural damage, and possible injury to passengers and crew. This action is intended to address the identified unsafe condition.

2005-26-53: The FAA is adopting a new airworthiness directive (AD) for all Pacific Aerospace Corporation (PAC) Ltd. Model 750XL airplanes. This AD contains the same information as emergency AD 2005-26-53 and publishes the action in the Federal Register. This AD requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are issuing this AD to reduce the maximum takeoff weight that will allow wing ultimate load requirements to be met. If wing ultimate load requirements are not met, wing failure could result and subsequent loss of control of the airplane.

2006-01-01: The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX, and 1125 Westwind Astra airplanes. This AD requires a one-time inspection for discrepancies of the nose wheel steering assembly of the landing gear, installing a warning placard on each nose landing gear door, and corrective action if necessary. This AD results from reports of failure of the steering brackets of the nose wheel steering assembly, and in one incident, loss of steering control. We are issuing this AD to find and fix these discrepancies, which could result in loss of steering control and consequent reduced controllability of the airplane.

2005-25-01: The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD requires modifying electrical harnesses located at the left- and right-hand wing roots; and re-routing and modifying the harness of the right-hand outboard flap actuator. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent chafed electrical harnesses, which could result in a potential source of ignition for fuel vapors near a fuel tank and consequent fire or fuel tank explosion.
