2004-01-13: The FAA supersedes Airworthiness Directive (AD) 97-22-16, which applies to certain Raytheon Model 1900, 1900C, and 1900D airplanes. AD 97-22-16 currently requires you to replace the bearings on the vent blower assemblies with improved design bearings and install a thermal protection device for the vent blowers. That AD resulted from reports of vent blower assembly bearings seizing and locking the blower motor on several of the affected airplanes. This AD retains the actions required in AD 97-22-16 for certain vent blower assemblies and requires you to incorporate further product improvement modifications on all affected vent blower assemblies. This AD is the result of reports that vent blower assemblies modified in accordance with AD 97-22-16 are still malfunctioning. We are issuing this AD to prevent smoke from entering the cockpit and cabin due to the current configuration of vent blower assemblies, which could result in the pilot becoming incapacitated or impairing her/hisjudgment. Such a condition could lead to the pilot not being able to make critical flight safety decisions and result in loss of control of the airplane.
2003-09-09 R1: This amendment revises Airworthiness Directive (AD) 2003-09- 09, which applies to certain Cessna Aircraft Company (Cessna) Models 441 and F406 airplanes. AD 2003-09-09 currently requires repetitively inspecting the fuel boost pump wiring inside and outside the boost pump reservoir and repair or replacement of the wiring as necessary. AD 2003-09-09 also requires eventual installation of an improved design wire harness and fuel boost pump as terminating action for the repetitive inspections. The way the compliance time is currently written puts certain airplane owners/operators in non-compliance with the AD. Also, the terminating action for the repetitive inspections did not provide the option of installing the protective sleeving modification for boost pump lead wires. This document clarifies and corrects the compliance time and provides the option of installing the protective sleeving modification for boost pump lead wires. The actions specified by this AD are intended to detect, correct, and prevent chafing and/or arcing of the fuel boost pump wiring, which could result in arcing within the wing fuel storage system. This condition could lead to ignition of explosive vapor within the fuel storage system.
2021-04-06: The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-7 airplanes.

The MCAI describes the unsafe condition as a missing release bar retaining screw on a Harley-type buckle assembly installed on a harness shoulder strap. This condition, if not corrected, could lead to loss of pilot restraint and consequently loss of airplane control or injuries to the crew. The FAA is issuing this AD to address the unsafe condition on these products.
2010-05-12: We are adopting a new airworthiness directive (AD) for the products listed above. 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: During a puncture voltage test of the aluminum-loaded paint on an in-service DHC-8 aircraft, conducted to validate an SFAR 88 [Special Federal Aviation Regulation No. 88] related task, Bombardier Aerospace (BA) discovered that the top wing fuel tank skin between Yw171.20 and Yw261.00 was painted with a non-aluminized enamel coating * * *. With this type of paint application, it is possible that, in the worst case scenario, a lightning strike could puncture the wing skin and create an ignition source in the fuel tank. Ignition sources inside fuel tanks, in combination with flammable fuel vapors, could result in fuel tank explosions and consequentloss of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
95-08-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Model DC-9-80 series airplanes and Model MD-88 airplanes, that requires an inspection to detect damage, burn marks, or discoloration at certain electrical plugs and receptacles of the sidewall lighting in the passenger cabin, and correction of discrepancies. This amendment would also require modification of the electrical connectors, which, when accomplished, would terminate the inspection requirement. This amendment is prompted by reports of failures of the electrical connectors in the sidewall fluorescent lighting, which resulted in smoke or lighting interruption in the passenger cabin. The actions specified by this AD are intended to prevent failures of the electrical connectors, which could result in poor socket/pin contact, excessive heat, electrical arcing, and subsequently, connector burn through and smoke in the passenger cabin.
2021-03-18: The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes.
