2024-16-12: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-243, -302, -343, and -941 airplanes. This AD was prompted by a determination that a certain aft bulkhead cover panel may have been made with a non-conforming material. This AD requires replacing the aft bulkhead cover panel and prohibits the installation of affected parts, 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.
2016-21-02: We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) [[Page 71592]] Model S-92A helicopters. This AD requires altering the fire bottle inertia switch wiring and performing a cartridge functional test of the fire extinguishing system. This AD was prompted by the inadvertent tripping of inertia-switches that has led to unintentional discharging of the fire bottles, leaving the helicopter's auxiliary power unit and engines without fire protection. The actions are intended to prevent unintentional and undetected fire bottle discharges and subsequent unavailability of fire suppression in case of a fire.
53-03-01: 53-03-01 NAVION: Applies to All Model B Aircraft Equipped With Hartzell HC-12 X20-8C/9333C-0 Propellers. Compliance required not later than March 15, 1953. Vibration tests conducted subsequent to the initial tests of the Hartzell HC-12 X20- 8C/9333C-0 propeller installed on the Lycoming GO-435 engine revealed vibration characteristics of a hazardous nature. Therefore, to prevent possible blade cracks and/or failures, the existing r.p.m. restriction placard should be revised as follows: "Avoid continuous ground operation between 1675 and 2150 engine r.p.m."
2024-19-12: The FAA is adopting a new airworthiness directive (AD) for certain DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-400 gliders and all Model DG-500 Elan Orion, DG-500 Elan Trainer, DG-500/20 Elan, DG-500/22 Elan, DG-500M, DG-500MB, DG-800A, DG-800B, DG-808C, DG-1000M, DG-1000S, and DG-1000T gliders. This AD was prompted by a report of a broken rod end at the upper end of the elevator pushrod in the fin (vertical tail) of a DG Aviation GmbH Model DG-300 glider. Depending on the glider model, this AD requires revising your existing glider maintenance manual to incorporate new procedures for elevator control circuit free play adjustment, performing an operational check of the free play adjustment of the automatic elevator hook-up, accomplishing corrective actions as required, and replacing the elevator pushrod end with a new part. The FAA is issuing this AD to address the unsafe condition on these products.
2016-20-10: We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of fuel leaking through fuel pump electrical connectors and of fuel pump electrical connector damage caused by the build-up of moisture behind the electrical connectors. This AD requires an inspection of the fuel pumps to identify their part numbers and replacement of affected pumps. We are issuing this AD to prevent a potential ignition source and a fuel leak through damaged fuel pump electrical connectors, which creates a flammability risk in an area adjacent to the fuel tank.
2016-20-15: We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B64/P2, -1B67/P2, -1B70/P2, -1B70C/ P2, -1B70/75/P2, and -1B74/75/P2 turbofan engines with engine assembly, part number (P/N) 2447M10G01 or P/N 2447M10G02, installed. This AD was prompted by a report of a significant fan rub event. This AD requires rework of the engine fan stator module assembly. We are issuing this AD to prevent failure of the fan blades and the load reduction device, loss of power to one or more engines, loss of thrust control, and loss of the airplane.
65-17-02: 65-17-02 CURTISS-WRIGHT: Amdt. 39-112 Part 39 Federal Register August 3, 1965. Applies to Model C-46 Series Airplanes. Compliance required within the next 300 hours' time in service after the effective date of this AD unless already accomplished. To prevent further erroneous indication by the landing gear position warning light that the landing gear is down and locked, accomplish the following: Modify the gear position warning light system by providing a separate position indication circuit and separate green light or other equivalent indicator for the "down and locked" position for each of the three landing gears in a manner approved by the Chief, Engineering and Manufacturing Branch, FAA Southern Region. This directive effective September 2, 1965.
2004-05-01 R1: The FAA is revising Airworthiness Directive (AD) 2004-05-01, which applies to certain Bombardier Inc. (formerly deHavilland Inc.) Model Otter DHC-3 airplanes that have turbine engines installed per one of three supplemental type certificates (STC). AD 2004-05-01 currently prohibits you from operating any affected airplane with these engine and propeller configurations unless a new STC for an elevator servo-tab with a redundant control linkage is installed. The FAA has since evaluated concerns, comments, and technical information related to all three STC configurations. Based on that evaluation, we have determined that further evaluation is necessary for the STCs owned by Texas Turbines Conversions, Inc., and Canada Turbine Conversions, Inc. Therefore, we are removing reference to these STCs from the AD, and the AD will only apply to those Bombardier Inc. airplanes that incorporate STC No. SA3777NM (A.M. Luton installation of Pratt and Whitney PT6A-34/ -135 engine). After further evaluation, we may initiate rulemaking action regarding airplanes with the Texas Turbines Conversions, Inc., and Canada Turbine Conversions, Inc., STC configurations. DATES: This AD becomes effective on May 25, 2004. On April 20, 2004 (69 FR 9523, March 1, 2004), the Director of the Federal Register previously approved the incorporation by reference of certain publications listed in the regulation. We must receive any comments on this AD by June 29, 2004.
2009-05-04: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-215-6B11 (CL-215T variant) and CL-215-6B11 (CL-415 variant) airplanes. This AD requires repetitive inspections for contamination of grease, bearing wear checks, grease applications of the rudder lower torque tube upper bearing, and a rudder upper hinge gap check; and related investigative and corrective actions if necessary. This AD results from a report of corrosion on the rudder lower torque tube upper bearing. We are issuing this AD to detect and correct corroded bearings which could lead to hinge deformation, and could result in a rudder jam and consequent reduced controllability of the airplane.
2004-08-14: The FAA adopts a new airworthiness directive (AD) for all Glasflugel Models Mosquito and Club Libelle 205 sailplanes. This AD requires you to replace the rudder actuator arm with an improved design rudder actuator arm. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent the rudder attachment actuator arm from failing due to ground handling damage. This failure could eventually result in reduced or loss of sailplane control.
