76-01-01: 76-01-01 CESSNA and REIMS AVIATION: Amendment 39-2483. Applies to Cessna Models A150K and A150L and Reims Aviation Models FA150K and FA150L airplanes certified in the acrobatic category, which have been modified in accordance with STC SA1809WE, incorporating Flint Aero auxiliary fuel tanks in the outboard wing panels. \n\n\tCompliance is required within ten days after the effective date of this AD, unless already accomplished. \n\n\tTo prevent the possibility of encountering high speed flutter with fuel in these auxiliary fuel tanks, accomplish the following: \n\n\t(a)\tAdjacent to the airspeed indicator and in full view of the pilot, attach a placard which reads: \n\n\t\tAirspeed Limits when auxiliary tanks contain any amount of fuel: \n\n\nVne (never exceed)\n= 162 MPH (141 knots) \nVno (max. structural cruising)\n= 120 MPH (104 knots) \nVa (maneuvering)\n= 109 MPH ( 95 knots) \n\t\n\t(b)\tAny equivalent method of showing compliance with this AD or any demonstration of freedom from flutter of this design must be approved by the Chief, Aircraft Engineering Division, FAA Western Region. \n\n\tThis amendment becomes effective January 9, 1976.
2018-07-21: We are superseding Airworthiness Directive (AD) 2005-12-16, which applied to all Fokker Services B.V. Model F28 Mark 0100 airplanes. AD 2005-12-16 required an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. This new AD requires an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary. This AD also removes airplanes from the applicability. This AD was prompted by reports of smoke in the passenger compartment during ground operations and in-flight, and a determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly. We are issuing this AD to address the unsafe condition on these products.
2014-25-06: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Airbus Model A310 series airplanes. This AD was prompted by a report of early ruptures on the levers of the nose landing gear (NLG) sequence valve. This AD requires a one-time inspection for damage of the landing gear sequence valve levers and pin shearing indicating areas on the NLG and the main landing gears (MLGs); and depending on findings, replacing the sequence valve and lever, or doing a one-time inspection to detect interference between control rods and sequence valves and corrective actions if necessary. We are issuing this AD to detect and correct interference between a landing gear leg and door, which could result in failure of that landing gear to extend and could damage the airplane and injure occupants.
2014-25-07: We are adopting a new airworthiness directive (AD) for certain Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes. This AD was prompted by a report of cracking at the splice plate of the frame (FR) 47 butt joint crossing area found during full-scale fatigue testing. This AD requires repetitive inspections for cracking of both sides of the splice plate of that frame butt joint crossing area, and corrective action if necessary. This AD also provides for an optional modification, which terminates the repetitive inspections. We are issuing this AD to detect and correct fatigue cracking of the splice plate of the FR 47 butt joint crossing area, which could result in reduced structural integrity of the airplane.
70-25-07: 70-25-07 BOEING: Amdt. 39-1125. Applies to Model 707 and 720 Series airplanes listed in Boeing Service Bulletin 2998, dated October 1, 1970, or later FAA approved revisions. \n\n\tTo prevent fluid bypassing within the Rudder Power Control Unit (PCU) accomplish the following: \n\n\tWithin the next 300 hours' time in service after the effective date of this AD, unless previously accomplished, modify the Rudder PCU in accordance with Boeing Service Bulletin 2998, dated October 1, 1970, or later FAA approved revision or an equivalent method approved by the Chief, Aircraft Engineering Division, FAA Western Region. \n\n\tThis amendment becomes effective December 11, 1970.
2025-04-03: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade- out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane damaging the fuselage, which caused loss of pressurization and subsequent emergency descent. The FBO events also resulted in cracks in the primary exhaust nozzle, potentially resulting in the departure of the primary exhaust nozzle and damaging a stabilizer or striking the fuselage and window. This AD requires an inspection or maintenance records check to determine if the primary exhaust nozzle has an affected part number and, for affected primary exhaust nozzles, an installation of bridge brackets onto the primary exhaust nozzle, or as an option, an installation of a serviceable primary exhaust nozzle. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
2014-25-01: We are superseding Airworthiness Directive (AD) 2010-13-04 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2010-13- 04 required modifying the nose landing gear (NLG) trailing arm. This new AD requires installing a new pivot pin retention mechanism. This new AD also adds airplanes to the applicability. This AD was prompted by a report of several missing or damaged pivot pin retention bolts. We are issuing this AD to prevent failure of the pivot pin retention bolt, which could result in a loss of directional control or loss of a NLG tire during take-off or landing.
2008-14-02 R1: We are revising Airworthiness Directive (AD) 2008-14-02 for Agusta Model AB139 and AW139 helicopters. AD 2008-14-02 required inspecting the fuselage frame to detect fatigue cracks which could lead to structural failure and subsequent loss of control of the helicopter. Since we issued AD 2008-14-02, Agusta developed a frame reinforcement modification, which supports extending the interval for inspecting the fuselage frame for a fatigue crack. This new AD requires inspecting the fuselage frame for a crack and reduces the applicability from AD 2008- 14-02 to exclude helicopters with the frame reinforcement modification. The actions of this AD are intended to detect a fatigue crack that could result in failure of the fuselage frame and subsequent loss of control of the helicopter.
2014-25-05: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of corroded, migrated, or broken spring pins of the girt bar floor fitting; in one case the broken pins prevented a door escape slide from deploying during a maintenance test. This AD requires replacing the existing spring pins at each passenger entry door at both girt bar floor fittings with new spring pins. We are issuing this AD to prevent broken or migrated spring pins of the girt bar floor fittings, which could result in improper deployment of the escape slide/raft and consequent delay and injury during evacuation of passengers and crew from the cabin in the event of an emergency.
2025-04-12: The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A, LEAP-1B, and LEAP- 1C engines. This AD was prompted by a manufacturer investigation that revealed a quality escape for low-pressure turbine (LPT) disks made from forgings with nonconforming grain size. This AD requires removal and replacement of the LPT stage 4 and stage 5 disks. The FAA is issuing this AD to address the unsafe condition on these products.
