2021-18-02: The FAA is adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. This AD was prompted by a report of a crack found on the forward pressure bulkhead web plate, at the edge of a bonded doubler. This AD requires a one-time inspection of the forward bulkhead for cracking, repair if necessary, and a report of inspection results, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

2005-25-12: The FAA is adopting a new airworthiness directive (AD) for Turbomeca Astazou XIV B and XIV H turboshaft engines that have operated with air intake noise suppressors. This AD requires ensuring proper installation of air intake noise suppressors, and ultrasonically inspecting 2nd stage axial compressor wheel blades operated in engines with improperly installed intake noise suppressors. This AD results from several reports of failure of 2nd stage axial compressor wheel blades. We are issuing this AD to prevent failure of 2nd stage axial compressor wheel blades, leading to in-flight engine shutdown and autorotation landing.

2021-16-12: The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by three occurrences of metallic debris in the engine oil lubrication system causing the 12 volts direct current (VDC) reference voltage to be shorted to ground and loss of important flight information to the pilot. This AD requires replacing a certain part- numbered relay panel assembly. The FAA is issuing this AD to address the unsafe condition on these products.

2021-06-01: The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This AD was prompted by a report that electronic circuit breakers (ECBs) were found in a locked state after maintenance, but before flight. This AD requires revising the airplane flight manual (AFM) to incorporate a procedure to check for the ECB status. The FAA is issuing this AD to address the unsafe condition on these products.

2007-06-08: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Some cases of turnbuckle adjusting screws fatigue failure have occurred, due to lateral load component applied by pilot's foot. Such events may lead to rudder and pedals disconnection.
We are issuing this AD to require actions to correct the unsafe condition on these products.

2021-19-04: The FAA is adopting a new airworthiness directive (AD) for Helicopteres Guimbal Model Cabri G2 helicopters with any metal bushing installed on the main rotor (M/R) swashplate guide bellcrank. This AD was prompted by a report of cracks discovered on the M/R scissor link during scheduled maintenance on several helicopters. This AD requires removing all metal bushings from service, visually inspecting the lug bore area and depending on the inspection results, removing certain parts from service and installing certain part- numbered plastic bushings. This AD also prohibits installing any metal bushing on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.

2021-16-11: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by a report of reduced yaw control, during an approach for landing, that resulted from rupture of the tail rotor gearbox (TGB) actuating rod and uncoupling of the steel sleeve from inside the external aluminum tube. This AD requires dye penetrant inspecting certain TGB actuating rods for a crack, and depending on the inspection results, replacing the TGB actuating rod, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

2021-16-07: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Defense and Space S.A. Model C-212-CB, C-212-CC, C-212- CD, C-212-CE, C-212-CF, C-212-DE, and C-212-DF airplanes. This AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) side fuselage skin and on a certain frame underneath the skin, near the leading edge of the wing. This AD requires repetitive inspections of the LH and RH side center wing fairings at a certain frame, around the wing leading edge for discrepancies (cracks), and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

2007-06-07: The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Models 58 and G58 airplanes with optional propeller unfeathering accumulators installed. This AD requires you to inspect the left propeller accumulator oil tube assembly for any chafing; replace the propeller accumulator oil tube assembly if any chafing is found; and reposition and secure with clamps both the left engine manifold pressure hose and its metal identification tags to avoid contact with other tubes, hoses, electrical wires, parts, components, and structure. This AD results from several reports on the affected airplanes of chafing damage on the left propeller accumulator oil tube assembly. We are issuing this AD to detect, correct, and prevent any chafing damage of the left propeller accumulator oil tube assembly, which could result in loss of engine oil. Loss of engine oil may lead to fire or smoke in the engine compartment, inability to unfeather the propeller, engine damage, or loss of engine power.

2021-16-01: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, - 113, -114, -115, -131, -132, -133, -151N, and -153N airplanes; Model A320 series airplanes; and Model A321 series airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
