2001-09-01: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200 and -300 series airplanes, that requires repetitive clearing of the drain passage at the aft end of the main landing gear (MLG) truck beam to ensure moisture and contaminants within the truck beam can properly drain; and, for certain airplanes, an internal inspection of the truck beam to detect discrepancies, and follow-on actions. This amendment is prompted by reports of fracture of MLG truck beams. The actions specified by this AD are intended to prevent stress corrosion cracking, leading to fracture of a MLG truck beam during ground operations, which could result in either reduced controllability of the airplane or a fire.
2001-09-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 series airplanes, that requires replacement of certain existing bushings of the aft trunnion of the outer cylinder of the main landing gear (MLG) with new bushings, and replacement of grease in an undercut on the aft trunnion, if necessary. The actions specified by this AD are intended to prevent stress corrosion cracking and consequent fracture of the aft trunnion of the outer cylinder of the MLG, which could result in collapse of the MLG. This action is intended to address the identified unsafe condition.
2004-18-03: The FAA is superseding an existing airworthiness directive (AD) for certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701), and CL-600-2D24 (Regional Jet Series 900) series airplanes. That AD currently requires revising the airplane flight manual to advise the flightcrew to monitor the fuel quantity in the center fuel tank throughout the flight. That AD also requires repetitive tests to detect a fuel leak between the wing fuel tanks and the center fuel tank; and further related investigative and corrective actions, if necessary. For certain airplanes, that AD also requires installation of flexible hoses and brackets in the fuel feed system. This AD reduces the compliance times for the repetitive checks, requires replacement of primary fuel feed ejectors with new ejectors, and provides an optional center fuel tank empty procedure. This AD is prompted by reports of cracking in the primary fuel ejector. We are issuing this AD to detect and correct cracking in any primary fuel ejector, which could cause fuel leakage into the center fuel tank, and could result in engine shutdown during flight. DATES: Effective September 17, 2004. The incorporation by reference of certain publications listed in the AD was approved previously by the Director of the Federal Register as of April 15, 2004 (69 FR 16780, March 31, 2004). We must receive any comments on this AD by November 1, 2004.
2001-09-04: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Dornier Model 328-300 series airplanes. This action requires repetitive inspections of motive flow check valves and adjacent parts for fuel leaks, and replacement of the valves, if leaks are detected. This action is necessary to prevent leakage of fuel from the motive flow check valves, which could result in fuel vapors coming into contact with fuel ignition sources. This action is intended to address the identified unsafe condition.
2019-23-09: The FAA is adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (BHTC) Model 427 helicopters. This AD requires inspecting the inboard skin of the vertical fin around the four tailboom attachment points. This AD was prompted by reports of cracked vertical fin skins that resulted from metal fatigue. The actions of this AD are intended to prevent an unsafe condition on these products.
2001-09-06: This amendment adopts a new airworthiness directive (AD) that applies to certain Cessna Aircraft Company (Cessna) Models 206H and T206H airplanes. This AD requires you to visually inspect the horizontal stabilizer attachment reinforcement brackets for the existence of seam welds and replace any reinforcement bracket found without seam welds. This AD is the result of a report that these parts were manufactured without seam welds. The actions specified by this AD are intended to detect and replace structurally deficient horizontal stabilizer attachment brackets. Continued use of such brackets could result in structural failure of the horizontal stabilizer with reduced or loss of control of the airplane.
2007-22-02: This amendment supersedes an existing airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (Bell) Helicopters. That AD currently requires inspecting each affected tail rotor blade (blade) forward tip weight retention block (tip block) and the aft tip closure (tip closure) for adhesive bond voids, and removing any blade with an excessive void from service. That AD also requires modifying certain blades by installing shear pins and tip closure rivets. This amendment contains the same requirements but expands the applicability to include other part and serial-numbered blades. This AD also clarifies the requirement to re-identify the modified blade by adding "FM" after the part number and also requires dynamically balancing the tail rotor. The existing AD was prompted by five occurrences of missing tip blocks or tip closures resulting in minor to substantial damage. This amendment was prompted by the determination that the AD should apply to other affected part and serial-numbered blades. The actions specified by this AD are intended to prevent loss of a tip block or tip closure, loss of a blade and subsequent loss of control of the helicopter.
52-04-03: 52-04-03 MARTIN: Applies to All Models 202 and 202A Aircraft. Compliance required not later than May 1, 1952. Eliminate pressure gage or place in heater fuel control box. (Trans World Airlines Engineering Order No. 5794 covers the elimination of the pressure gage.)
2001-08-25: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A330-301, -321, -322, and -342 series airplanes and certain Airbus Model A340 series airplanes. This action requires reinforcement of the wing structure at the inboard pylon rear pickup area. This action is necessary to prevent fatigue cracking of the bottom skin and reinforcing plate of the wing due to bending, which could lead to reduced structural integrity of the airplane wing. This action is intended to address the identified unsafe condition.
2019-23-01: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; A319-111, -112, -113, -114, - 115, -131, -132, and -133 airplanes; A320-211, -212, -214, -216, -231, -232, -233, -251N, -252N and -271N airplanes; and 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. The FAA is issuing this AD to address the unsafe condition on these products.
