Airworthiness Directive

November 12, 2012 - 1:20pm

The FAA plans to issue Airworthiness Directive FAA-2012-1111 to address wiring issues on the Beechjet 400A. The AD was prompted by a report that the wiring for the five-volt direct-current system is undersized and does not have adequate circuit protection for the smaller-gauge wire. This proposed AD would require installing an in-line fuse in the five-volt DC system for each of the five instrument lighting control power supplies.

The FAA is proposing an Airworthiness Directive for the Eurocopter AS332C, L and L1 to require initial and repetitive inspections of the outer skin, butt strap and fuselage frame for a crack and modification of the helicopter. The proposed AD is prompted by an AD issued by the EASA that states a crack was discovered in a fuselage frame during a daily check.

The FAA is adopting a new Airworthiness Directive–2012-CE-026-AD–for 35 Hawker Beechcraft C90GTi King Air twin turboprops. This AD was prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. This AD requires replacing the incorrect wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking all necessary corrective actions. The new AD becomes effective Nov. 27, 2012.

The FAA is proposing to adopt a new airworthiness directive for all Dassault Falcon 50s. The proposed AD was prompted by a manufacturer revision to the airplane maintenance manual. The maintenance tasks and airworthiness limitations, as specified in the Falcon 50 AMM Chapter 540, have been identified as mandatory actions for continued airworthiness and include a corrosion-prevention and -control program and checking of overpressure tightness on pressurization control regulating valves.

Amac Aerospace has been granted Boeing 747-400 and 747-8 Part 145 approval. It allows the MRO provider to offer base and line maintenance services for the aircraft with no restrictions. The company also recently announced Amac Aerospace Basel has received UAE CAMO approval authorizing it to provide continuous airworthiness management services on UAE-registered aircraft.

The FAA proposes an airworthiness directive for the Cessna 500, 501, 550, 551, S550, 560, 560XL and 650 prompted by multiple reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the air-conditioning (A/C) motor.

The FAA is proposing an Airworthiness Directive for the Eurocopter AS332C, AS332L and AS332L1. It is based on reports of electro-valve power supply disruptions while the helicopter is on the ground. It causes the landing gear to retract and the helicopter nose to drop, resulting in damage to the forward section of the helicopter’s underside. The AD would require modifying the main landing-gear control panel 33G, connector 100G and wiring.

An FAA review has found that some Gulfstream Aerospace G150s might not meet the takeoff requirements contained in the type’s airplane flight manual (AFM) because data for runway slope and anti-ice corrections to V1 and takeoff distances were originally “developed in a non-conservative manner.”

The FAA has issued an airworthiness directive for the Cessna 750’s auxiliary power unit DC generator prompted by overvoltage events. The AD requires replacing the APU generator control unit to prevent DC generator overvoltage events, which could result in smoke in the cockpit and loss of avionics and electrical systems. On June 25 a notice of proposed rulemaking was issued proposing the APU generator control unit be replaced and the public was given the opportunity to comment.

September 12, 2012 - 2:15pm

The FAA has issued an airworthiness directive for all Eurocopter SA365N, SA365N1, SA366G1, AS365N2, AS365N3, EC155B and EC155B1s. The AD was prompted by the discovery of a cracked main rotor mast nut. This condition, if not corrected, could lead to complete failure of the mast nut, resulting in failure of the rotor mast and loss of control of the helicopter.
