Airworthiness Directive · Amendment 39-14583 · Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and A310-300 Series Airplanes
Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and A310-300 Series Airplanes
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and A300 C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes on which Airbus Modification 3881 has been done in production or Airbus Service Bulletin A310-21-2012 has been done in service; certificated in any category; excluding airplanes on which Airbus Modification 12921 has been done in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300-600, A310-200, and A310-300 series airplanes. This AD requires modifying the forward outflow valve of the pressure regulation subsystem. This AD results from a report of accidents resulting in injuries occurring on in-service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure, causing the doors to rapidly open. In these accidents, the buildup of residual pressure in the cabin was caused by the blockage of the outflow valve by an insulation blanket. We are issuing this AD to prevent an insulation blanket or other debris from being ingested into and jamming the forward outflow valve of the pressure regulation subsystem, which could lead to the inability to control cabin pressurization and adversely affect continued safe flight of the airplane.
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: Modify the forward outflow valve of the pressure regulation subsystem by doing all the actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6149 (for Model A300-600 series airplanes) or A310-53-2121 (for Model A310-200 and A310-300 series airplanes) both Revision 01 dated September 12, 2005, as applicable. Accomplishing the modification before the effective date of this AD, in accordance with Airbus Service Bulletin A300-53-6149 or A310-53-2121, both dated February 25, 2005, as applicable, is acceptable for compliance with the modification in this paragraph.
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.
