2023-05-10: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD was prompted by a report that an A319 airplane lost the right- hand front windshield in flight. Due to the design similarity, this condition can also exist or develop on Model A330 and A340 airplanes. This AD requires repetitive detailed inspections (DET) and electrical test measurements (ETM) of the affected parts and applicable corrective action, and prohibits the installation of affected parts under certain conditions, 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.

2016-08-18: We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. This AD was prompted by a report of an engine fire caused by a leak in the fuel pump inlet hose. This AD requires inspecting the fuel hose assembly and the turbocharger support assembly for proper clearance between them, inspecting each assembly for any sign of damage, and making any necessary repairs or replacements. We are issuing this AD to correct the unsafe condition on these products.
|
2009-02-02: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from 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 describes the unsafe condition as:
A detailed inspection in a M26 airplane revealed a significant chafing of the aileron control cable against the wing rib in the fuselage-to-wing area of transition and an abnormal wearing of pulleys' gorges as well.
Such damage can only be evidenced on control cables which travel in pulleys either limited in rotation or seized.
If left uncorrected, this condition, which could also occur on the elevator or rudder control system, could lead to loss of one or more primary flight controls and consequent reduced controllability of the airplane.
This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Compliance as indicated required on all airplanes with 30,000 hours or more total time in service unless already accomplished.
To detect cracks in the wing front spar lower caps, accomplish the following:
(1) As soon as practicable, but not to exceed 10 hours' time in service following the effective date of this AD, if the airplane is to be flown, visually inspect, on a daily basis, from the exterior of the wing, both left and right wing front spar lower caps in areas adjacent to each side of main landing gear drag strut attachment fittings for cracks until inspection in (2) below is accomplished.
(2) Within the next 100 hours' time in service after the effective date of this A.D., unless already accomplished within the last 500 hours' time in service, and thereafter at intervals not to exceed 600 hours' time in service from the last inspection, accomplish the following:
(a) Gain access to the wing interior in the area described in (1) above by removal of lower wing skin access cover.
(b) Perform inspection described in (1) above from the interior of the wing.
(3) If cracks are found as the result of the inspections described in (1) or (2) above, repair before further flight in a manner approved by the Chief, Aircraft Engineering Division FAA Western Region.
This amendment becomes effective March 26, 1973.

2016-11-04: We are superseding Airworthiness Directive (AD) 2011-23-05 for all The Boeing Company Model 737-300, -400, and -500 series airplanes. AD 2011-23-05 required repetitive inspections for cracking of the 1.04- inch nominal diameter wire penetration hole, and applicable related investigative and corrective actions. This new AD adds new inspection areas, a modification that terminates certain inspections, post- modification inspections, and repair if necessary. This AD was prompted by an evaluation by the design approval holder (DAH) that indicates the fuselage frames and frame reinforcements are subject to widespread fatigue damage (WFD). We are issuing this AD to detect and correct fatigue cracking of the fuselage frames and frame reinforcements that could \n\n((Page 34872)) \n\nresult in reduced structural integrity of the airplane.
