Airworthiness Directive · Amendment 39-14625 · Airbus Model A300 B4-600R Series Airplanes, A300 C4-605R Variant F Airplanes, A300 F4-600R Series Airplanes; and Model A310-300 Series Airplanes
Airbus Model A300 B4-600R Series Airplanes, A300 C4-605R Variant F Airplanes, A300 F4-600R Series Airplanes; and Model A310-300 Series Airplanes
This AD applies to Airbus Model A300 B4-605R and B4-622R airplanes, A300 C4-605R Variant F airplanes, A300 F4-605R and F4-622R airplanes; and Model A310-304, -322, -324, and -325 airplanes; certificated in any category, except those airplanes on which Airbus Modification 12897 has been accomplished in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus transport category airplanes. This AD requires replacing the existing vent float valve with a new, improved vent float valve. This AD results from reports of failure of the vent float valve in the left-hand outboard section of the trimmable horizontal stabilizer. We are issuing this AD to prevent, in the event of a lightning strike to the horizontal stabilizer, sparking of metal parts and debris from detached and damaged float valves, or a buildup of static electricity, which could result in ignition of fuel vapors and consequent fire or explosion.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 36 months after the effective date of this AD: Replace Intertechnique vent float valve, part number (P/N) L87-13-001, in the trim tank with P/N L87-13-003; in accordance with Airbus Service Bulletin A300-28-6081, Revision 01, dated October 11, 2005 (for Model A300 B4-605R and B4-622R airplanes, A300 C4-605R Variant F airplanes, and A300 F4-605R and F4-622R airplanes); or A310-28-2155, Revision 01, dated October 17, 2005 (for Model A310-304, -322, -324, and -325 airplanes).
Accomplishment of the actions required by paragraph (f) of this AD that are done before the effective date of this AD in accordance with Airbus Service Bulletin A300-28-6081 (for Model A300 B4-605R and B4-622R airplanes, A300 C4-605R Variant F airplanes, and A300 F4-605R and F4-622R airplanes) or A310-28-2155 (for Model A310-304, -322, -324, and -325 airplanes), both dated February 16, 2005, is acceptable for compliance with the requirements of paragraph (f) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
