2014-25-52: We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes and Model A340-200, -300, -500, and -600 series airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires revising the airplane flight manual to advise the flightcrew of emergency procedures for abnormal Alpha Protection (Alpha Prot). This AD was prompted by a report of Angle of Attack (AoA) probes jamming on an in-service Airbus Model A321 airplane. We are issuing this AD to ensure that the flightcrew has procedures to counteract the pitch down order due to abnormal activation of the Alpha Prot. An abnormal Alpha Prot, if not corrected, could result in loss of control of the airplane.
2003-14-05: This amendment adopts a new airworthiness directive (AD) that is applicable to all McDonnell Douglas Model 717 airplanes. This action requires repetitive inspections for cracking of the support fitting assemblies and stop pads of the main spoiler actuators, and follow-on actions. This action is necessary to find and correct cracking of the support fitting assemblies of the main spoiler actuators, which could result in damage of adjacent structure such as the rear spar or upper skin panel, and consequent reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
2025-04-13: The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model PW1519G, PW1521G, PW1521GA, PW1521G- 3, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A engines with a certain high-pressure compressor (HPC) 7th-stage axial rotor installed. This AD was prompted by an analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced an HPC 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an aborted takeoff. This AD requires performing initial and repetitive angled ultrasonic inspections (AUSI) of certain HPC 7th-stage axial rotors for cracks and replacing the HPC 7th-stage axial rotors if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
2014-26-10: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a determination that the maintenance actions for airplane systems susceptible to aging must be mandated. This AD requires revising the maintenance or inspection program to incorporate more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to mitigate the risks associated with aging effects of airplane systems. Such aging effects could change the characteristics leading to an increased potential for failure, which could result in failure of certain life-limited parts, and could reduce the structural integrity or reduce controllability of the airplane.
2014-26-07: We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON and FAN JET FALCON SERIES C, D, E, F, and G airplanes. This AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce changes to the maintenance requirements and airworthiness limitations. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a new airworthiness limitations section. We are issuing this AD to prevent reduced structural integrity of the airplane.
73-06-02: 73-06-02 AERO COMMANDER: Amdt. 39-1606. Applies to all Models 500, 500A, 500B, 500U, 520, 560, 560A, 560E, 560F, 680, 680E, 680F, 680F(P), 680FL, 680FL(P) and 720 series airplanes certificated in all categories. Compliance required within the next 200 hours' time in service after the effective date of this AD, unless already accomplished. To prevent siphoning of fuel from the fuel tanks and thereby contribute to fuel exhaustion with resultant stoppage of both engines, accomplish the following: a. On Models 520 and 560, serial numbers 1 through 230, replace the standard fuel cap assemblies with non-siphoning fuel cap assemblies, Aero Commander Kit No. 87A-1. b. On the following models, replace the standard fuel cap assemblies with non- siphoning fuel cap assemblies, Aero Commander Kit No. 87A-2 (optional fuel caps already installed by use of Aero Commander Kit No. 87 are acceptable): (1) Models 500, 500A, 500B, 500U, 560A, 560E, 560F, 680, 680E, 680F, 680F(P), 680FL(P) and 720, serial numbers 231 through 1854. (2) Model 680FL, serial numbers 1261 through 1738. c. The compliance time for this AD may be adjusted up to a maximum of 50 hours to coincide with the aircraft's annual or 100 hour scheduled inspection. Aero Commander Custom Kit No. 87A contains the hardware and instructions necessary to accomplish this modification. Equivalent replacement parts approved by the Chief, Engineering and Manufacturing Branch, Flight Standards Division, Southwest Region, Federal Aviation Administration, Fort Worth, Texas, may be used. This amendment becomes effective March 19, 1973.
62-26-02: 62-26-02 GRUMMAN: Amdt. 513 Part 507 Federal Register December 6, 1962. Applies to Model G-159 Aircraft Serial Numbers 1 through 93, Except Numbers 75 and 76, and to Aircraft Serial Number 114. Compliance required as indicated. Abnormal fuel system operation has caused structural damage to the wing area of Grumman Model G-159 airplanes. As this condition is likely to exist on other airplanes of the same type design, accomplish the following: (a) Unless already accomplished, the following inspection is required prior to further flight, except that if the airplane is presently located at a base where the equipment and personnel necessary to conduct such an inspection are not available, the airplane may be ferried without passengers to a base where such equipment and personnel are available: (1) Defuel the left and right wing tanks. (2) Remove the inspection covers in the upper surface of the wings between the fuselage and the nacelle and between the nacelle and the fuel filler caps. (3) Inspect for damage to the wing structure in the integral tanks. Pay particular attention to the three top and three bottom rivets in the vertical stiffeners on the ribs. (b) Unless already accomplished, the following repair for damaged aircraft and the following modification for all aircraft are required prior to further flight except that if the damage is confined to the stiffener and rib attachments, the airplane may be operated under a special flight permit (CAR 1.76) to a base where the repair and modification may be made: (1) Repair damage in accordance with Grumman FAA approved instructions or equivalent approved by Chief, Engineering and Manufacturing Branch, FAA Eastern Region, New York International Airport, New York. (2) Modifying by removing the fuel vent flow valve Parker P/N 119-578735 from each tank and drilling a 5/32-inch diameter hole in the valve body in accordance with Grumman Gulfstream Service Change No. 154. After brush-coating the hole with EC-776 or FAA approved equivalent, reinstall the valve. NOTE. - Aircraft Serial Nos. 1, 7, 12, 26 and 91 already incorporate this modification. (Grumman telegram dated November 12, 1962, to all Gulfstream operators and Grumman Service Change No. 154 cover this same subject.) This directive effective upon publication in the Federal Register for all persons except those to whom it was made effective immediately by telegram dated November 15, 1962.
2014-26-09: We are superseding Airworthiness Directive (AD) 2014-03-05, for certain Bombardier, Inc. Model BD-700-1A10 airplanes. AD 2014-03-05 required modification of the air data probes and sensors. This new AD continues to require modification of the air data probes and sensors. This new AD also adds airplanes to the applicability. This AD was prompted by a report that the manufacturer has determined that some completion centers used the heater current/brake temperature monitor unit (HBMU) logic circuit to control the line voltage of the drain mast heaters. We are issuing this AD to detect and correct an unannunciated failure of two pitot static probe heaters, which could affect controllability of the airplane in icing conditions.
2025-04-11: The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by the discovery that a partial loss of thrust after an engine failure during a required navigation performance authorization required (RNP- AR) approach under certain weight, altitude and temperature (WAT) conditions, may lead to a descent below the specified path guidance. This AD requires a revision to the existing airplane flight manual (AFM), to incorporate updated WAT tables for RNP-AR approach operations. The FAA is issuing this AD to address the unsafe condition on these products.
2014-23-01: We are superseding airworthiness directive (AD) 2013-15-09 for all Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engine models with certain second-stage high-pressure turbine (HPT) air seals installed. AD 2013- 15-09 required initial and repetitive inspections for cracks in second- stage HPT air seals. This new AD expands the applicability of AD 2013- 15-09 to include additional part numbers (P/Ns), requires removal of the mating hardware if the second-stage HPT air seal is found with a through-crack, and adds a mandatory terminating action. This AD was prompted by reports of cracking in the original location on two additional P/Ns and reports of through-cracks in a new location in the second-stage HPT air seal. We are issuing this AD to prevent failure of the second-stage HPT air seal, which could lead to uncontained engine failure and damage to the airplane.
