Airbus Model A319, A320, and A321 Series Airplanes
This AD applies to Airbus Model A319, A320, and A321 series airplanes, certificated in any category; as identified in Table 1 of this AD.
| Airbus model | Having the following Airbus modification installed in production— | Or the following Airbus service bulletin incorporated in service— | But not having the following Airbus modification installed in production— |
|---|---|---|---|
| A319 series airplanes | 24486 | A320-21-1140 | 32616 |
| A320 series airplanes | 20084 | A320-21-1048 | 32616 |
| A321 series airplanes | 22596 | (1) | 32616 |
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This AD requires replacing the cargo ventilation extraction duct at frame 65 with a new duct, and relocating the temperature sensor in the aft cargo compartment. This AD is prompted by a report indicating that, during a test of the fire extinguishing system, air leakage around the temperature sensor for the aft cargo compartment reduced the concentration of fire extinguishing agent to below the level required to suppress a fire. We are issuing this AD to prevent air leakage around the temperature sensor for the aft cargo compartment, which, in the event of a fire in the aft cargo compartment, could result in an insufficient concentration of fire extinguishing agent, and consequent inability of the fire extinguishing system to suppress the fire.
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 24 months after the effective date of this AD: Replace the ventilation extraction duct with a new duct and relocate the aft cargo compartment temperature sensor by accomplishing all of the actions specified in the Accomplishment Instructions of Airbus Service Bulletin A320-21-1141, Revision 01, dated December 17, 2004.
Modifications accomplished before the effective date of this AD in accordance with Airbus Service Bulletin A320-21-1141, dated April 7, 2004, are acceptable for compliance with paragraph (f) of this AD.
