2022-14-11: The FAA is adopting a new airworthiness directive (AD) for certain Stemme AG (type certificate previously held by Stemme GmbH & Co. KG) Model Stemme S 12 gliders. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as a deviation in the construction of the connection of the inner wing to the outer wing, resulting in a wrong positioning of the glass-fiber reinforced plastic (GFRP) blocks. This AD requires inspecting the left-hand (LH) and right-hand (RH) outer wing spars for correct positioning of the GFRP blocks and, if incorrect positioning is found, repairing of the reinforcement blocks. The FAA is issuing this AD to address the unsafe condition on these products.
2007-17-01: The FAA is superseding an existing airworthiness directive (AD) for General Electric (GE) CF6-80E1 series turbofan engines. That AD currently requires removing electronic control unit (ECU) software version E.1.M. or earlier installed software, and installing improved software for the ECU. This AD requires removing software version E.1.N or earlier from the engine ECU. Engines with the new version software will have increased margin to flameout. This AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Although the root cause investigation is not yet complete, we believe that exposure to ice crystals during flight is associated with these flameout events. We are issuing this AD to minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.
2022-13-12: The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE Passport 20-17BB1A, GE Passport 20- 18BB1A, and GE Passport 20-19BB1A model turbofan engines. This AD was prompted by fuel leakage from the fuel nozzle to fuel manifold coupling nut connections. This AD requires a visual inspection of the core compartment, a re-torque of the core compartment coupling nuts, a ground power assurance check, and a borescope inspection. Depending on the results of the inspections, this AD requires operators to perform applicable maintenance in accordance with their FAA-approved instructions for continued airworthiness. The FAA is issuing this AD to address the unsafe condition on these products.
2007-16-16: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: It has been found the occurrence of smoke on the passenger cabin originated from the valance panel lighting system wiring. We are issuing this AD to require actions to correct the unsafe condition on these products.
2007-16-14: The FAA is adopting a new airworthiness directive (AD) for all Taylorcraft A, B, and F series airplanes. This AD requires you to initially inspect the left and right wing front and aft lift struts for corrosion and cracks, replace any cracked strut or strut with corrosion that exceeds certain limits with either sealed or non-sealed struts, and repetitively inspect any non-sealed struts. This AD results from inspections where several different struts were found with moderate to severe corrosion and required strut replacement. We are issuing this AD to detect and correct corrosion or cracks in the right and left wing front and aft lift struts. This condition, if not corrected, could result in failure of the lift strut and lead to in-flight separation of the wing with consequent loss of control.
2022-12-04: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 series airplanes, Model A330-200 Freighter series airplanes, and Model A330-300 series airplanes. This AD was prompted by a determination that certain service information specified in AD 2018-20-19 contained instructions that could be misleading, resulting in a necessary inspection not being accomplished on certain airplanes. This AD requires a rototest for certain modified airplanes for any crack around the right-side upper and lower bulk door support or door latch fitting holes at certain bulk cargo door frames, or repetitive inspections for any crack at certain fittings, and on- condition actions, 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.
2007-16-19: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, and 747-400 series airplanes. This AD requires doing repetitive detailed inspections for cracking of the aft tension tie channels from body station (BS) 1120 to BS 1220 and from BS 880 to BS 1100, and corrective actions if necessary. This AD results from cracks found in the aft tension tie channels at four station locations, on a Model 747-200B series airplane that had been modified to a special freighter. We are issuing this AD to detect and correct cracking of the aft tension tie channels; failure of more than one tension tie could result in rapid depressurization of the airplane.
2022-11-16: The FAA is adopting a new airworthiness directive (AD) for all British Aerospace (Operations) Limited Model Jetstream Model 3101 airplanes and British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as stress corrosion cracking of the primary flight control cable terminals. This AD requires repetitively inspecting the turnbuckle type control cable terminals in the rudder and elevator primary flight control circuits for corrosion, pitting, and cracking and, depending on the inspection results, replacing an affected cable assembly. The FAA is issuing this AD to address the unsafe condition on these products.
2007-16-13: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 757-200, -200PF, and -200CB series airplanes. The existing AD currently requires repetitive inspections of the shim installation between the vertical flange and bulkhead, and repair if necessary. This new AD adds, for certain airplanes, an inspection for cracking of the four critical fastener holes in the horizontal flange, and repair if necessary. This AD results from reports of cracking in the pylon under bolts that appear to be undamaged during the existing AD inspections. We are issuing this AD to detect and correct cracks, loose and broken bolts, and shim migration in the joint between the aft torque bulkhead and the strut- to-diagonal brace fitting, which could result in damage to the strut and consequent separation of the strut and engine from the airplane.
2022-11-06: The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This AD was prompted by a report of a protective sheath, installed around a fixed flight control rod, which should have been removed during assembly. This AD requires borescope inspecting certain parts, and removing any foreign object if detected, 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.
