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.
The FAA proposes an airworthiness directive for the Cessna 750 Citation X prompted by reports of direct current (DC) generator overvoltage events. The generator control unit (GCU) overvoltage protection circuit can become damaged and allow high voltage to pass through to the airplane systems and electrical components, which, if not corrected, could result in smoke in the cockpit and loss of avionics and electrical systems.
The EASA and FAA have issued new emergency Airworthiness Directives (ADs) for the Eurocopter EC135 after detection of cracks on the lower hub-shaft flange of two more of the light twins. The ADs require repetitive preflight inspections.
The FAA is proposing an airworthiness directive for variants of the Bombardier Challenger 600 and 601. There have been several reported incidents of jamming/malfunctioning of the left-hand engine thrust control mechanism on the affected airplanes.
The FAA proposed an Airworthiness Directive for the Eurocopter SA365N, SA365N1, AS365N2, AS365N3, EC155B, EC155B1, SA365C, SA365C1, SA365C2 and SA366G1. It is prompted by reports of corrosion on the main gearbox (MGB) casing lower area between the two servo-control anchor-fitting attachment ribs. The proposed actions are to detect corrosion on the MGB casing, which could lead to a crack, failure of the MGB and subsequent loss of control. The FAA is accepting comments until August 17.
