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.
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.
The FAA is proposing an airworthiness directive for MD Helicopters 369Ds, 369Es, 369Fs and 369FFs with specific serial-numbered tailboom assemblies. The AD was prompted by the discovery of short-edge margin conditions on two tailboom assemblies.
The FAA has published a notice of proposed rulemaking to adopt a new airworthiness directive for the Bombardier CL-600 series, including the Challenger 601, 601-3A, 601-3R and 604. It is prompted by reports of cracking found on the upper and lower web of the engine support beam.
The FAA plans to adopt a new airworthiness directive for the Hawker Beechcraft King Air C90GTi. The AD is prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. The AD would require replacing incorrect gauge wires in certain electrical power wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking the necessary corrective actions.
The FAA is proposing to rescind an Airworthiness Directive (AD 200-07-11) issued for all Piaggio Avantis to prevent the brake hydraulic fluid from leaking. It was prompted by reports of brake assembly rods contacting the brake valve tubing, which could compromise the airplane’s ability to stop during ground operations. Since then the FAA has determined it is no longer an unsafe condition and that regularly scheduled annual inspections address the subject. The FAA is taking comments until September 4.
The FAA is proposing to adopt a new airworthiness directive for all Eurocopter BK117C2 helicopters with certain generator control units (GCU) installed. The AD is prompted by reports of internal short circuits in certain GCUs.
Software company SkyBooks is now offering its version 4.7 aircraft operations management system in two product lines, for flight operations or maintenance management. Both versions are available as either analyst- or user-managed.
“Segmentation in two functional areas and bundling core offerings is a result of customer requests and new feature enhancements,” said CEO John Willis.
