2007-25-10: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: A rotating rod in the trailing edge flap control linkage broke in flight. Investigations revealed that the rotating rod had been installed in the wrong side during a maintenance operation. This incorrect installation caused a contact between the rotating rod and its retaining bracket leading, after some time in operation, to the rod breakage and flap asymmetry situation. The consequence on the airplane of the flap asymmetry combined with a latent failure of the asymmetry detection system is classified as a catastrophic failure condition. The unsafe condition is failure of the rotating rod in the control linkage of the trailing edge flap and consequent flap asymmetry during the approach to landing, which could result in reduced controllability of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2020-03-12: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by two reports of abnormal operation of the components of the ENG START panel or ECP due to liquid spillage in the system, and the subsequent uncommanded engine inflight shutdown (IFSD) of one engine in each case. This AD requires revising the existing airplane flight manual (AFM) to define a liquid-prohibited zone in the flight deck and provide procedures following liquid spillage on the center pedestal, 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.

If the engine continues to run for the full seven (7) minute period, replace the fuel selector valve with the appropriate serviceable fuel valve and repeat Paragraph I. An equivalent means of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region. Piper Service Bulletin No. 519 also pertains to this same subject. This amendment becomes effective September 10, 1976.
2020-02-15: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a report that easy removal of the portable oxygen bottle from its support bracket may not always be possible on certain installations. This AD requires installation of a modified top bracket and new middle bracket on all affected portable oxygen bottle installations. The FAA is issuing this AD to address the unsafe condition on these products.
86-19-05: 86-19-05 CASA: Amendment 39-5406. Applies to CASA Model C-212 series airplanes as listed in CASA Service Bulletin 212-24-33, Revision 2, dated October 23, 1985, certificated in any category. Compliance is required within 90 days after the effective date of this AD. To preclude the loss of navigation and communications capability due to a single electrical system failure, accomplish the following, unless previously accomplished: A. Modify the electrical system in accordance with CASA Service Bulletin 212-24- 33, Revision 2, dated October 23, 1985. B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. Allpersons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to Construcciones Aeronauticas, S.A., Getafe, Madrid, Spain. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. This amendment becomes effective October 2, 1986.
76-15-07: 76-15-07 PIPER: Amendment 39-2680. Applies to Models PA-31-325, Serial Nos. 31-7400990, 31-7512006 through 31-7512058; PA-31-350, Serial Nos. 31-5001 through 31-7552108 certificated in all categories. To prevent possible hazards in flight associated with loose elevator balance weights, accomplish the following within the next fifty hours in service from the effective date of this AD unless previously accomplished: a. Alter the elevator balance weight attachment in accordance with Piper Elevator Balance Weight Modification Kits No. 761 040 applicable to Model PA-31-325 or No. 761 041 applicable to Model PA-31-350 or approved equivalent alterations. b.

This amendment is effective August 3, 1976.
2007-23-01: The FAA is superseding an existing airworthiness directive (AD), which applies to Goodrich evacuation systems approved under TSO- C69b and installed on certain Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-541 and -642 airplanes. That AD currently requires inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, and corrective action if necessary. For certain airplanes, this new AD requires an additional inspection to determine the part number of the pressure relief valves, and corrective action if necessary. This AD results from a report indicating that, during maintenance testing, the pressure relief valves on the affected Goodrich evacuation systems did not seal when activated, which caused the pressure in the escape slide/raft to drop below the minimum allowable raft mode pressure. We are issuing this AD to prevent loss of pressure in the escape slides/rafts after an emergency evacuation, which could result in inadequate buoyancy to support the raft's passenger capacity during ditching, and increase the chance for injury to raft passengers. DATES: This AD becomes effective December 11, 2007. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 11, 2007. On July 17, 2006 (71 FR 33606, June 12, 2006), the Director of the Federal Register approved the incorporation by reference of Goodrich Service Bulletin 25-355, dated July 25, 2005.
