Airworthiness Directive

March 1, 2013 - 12:10am

Since when is an Emergency AD used to ground an aircraft fleet, as it has been in the case of the Boeing 787 Dreamliner? First off, let me be clear that if anything good can be said of the Boeing Dreamliner nightmare it’s that no one had to die before the FAA would take definitive action to ground the 787 until its battery fire problems could be investigated properly.

The FAA is revising an earlier proposed airworthiness directive for the Eurocopter BO105A/C/LS/LS A-3 and 105S. The earlier AD proposed inspecting for debonding of the erosion protective shell (abrasion strip) on the leading edge of each main rotor blade. This SNPRM proposes to revise those inspection requirements by identifying specific dates of replacement of the applicable parts and identifying a specific inspection method to discover debonding of an abrasion strip.

Gulfstream Aerospace technicians were responsible for uncovering a preflight systems test malfunction that led to last week’s FAA Airworthiness Directive on all 260 G350/450s. The December 12 directive–2012-NM-219-AD–took effect December 17 and addresses the flap/stabilizer electronic control unit cockpit crewmembers normally test before the first flight of the day.

The FAA has issued a supplemental notice of proposed rulemaking revising an earlier proposed airworthiness directive for Cessna 525 Citations equipped with certain part number air conditioning compressor motors. The NPRM proposed to require inspection of the number of hours on the A/C compressor hour meter, inspection of the logbook and replacement of the brushes on specified compressor motors or deactivation of the A/C system until replacement of the brushes.

The FAA on Wednesday issued an airworthiness directive (AD) requiring inspection of Boeing 787-8 engine fuel feed manifold couplings after receiving reports of fuel leaks on two in-service aircraft.

Operations of the latest version of Eurocopter’s ubiquitous light single, the AS350B3e Ecureuil/AStar, have been affected by an emergency service bulletin and accompanying emergency airworthiness directive (AD).

Under the restrictions, the helicopter’s true airspeed is limited to 100 knots to reduce dynamic loads on the tail rotor. In addition, repetitive inspections must be conducted, with maximum intervals of three flight hours, on the laminated half-bearings.

The FAA is adopting a new Airworthiness Directive that supersedes an existing airworthiness directive for the MD Helicopters MD900. It requires a visual inspection and, if necessary, an eddy-current inspection of the main rotor lower hub assembly (lower hub) for a crack. If a crack exists, the AD requires replacing the lower hub with an airworthy lower hub before further flight.

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.

October 31, 2012 - 12:05pm

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.
