| 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— |
|---|---|---|---|
| A318-111 and -112 airplanes | Not applicable | Not applicable | 33232 |
| A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes | 25642 or 26213 | A320-52-1088 | 33232 |
| A320-111 airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes | 26213 or 26603 | A320-52-1088 | 33232 |
| A321-111, -112, and -131 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes | 26213 or 26603 | A320-52-1088 | 33232 |
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100 series airplanes; Model A319-100 series airplanes; Model A320-111 airplanes; Model A320-200 series airplanes; Model A321-100 series airplanes; and Model A321-200 series airplanes. This AD requires replacing the water drain valves in the forward and aft cargo doors with new valves. This AD results from a report indicating that, during a test of the fire extinguishing system, air leakage through the water drain valves in the forward and aft cargo doors 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 through the water drain valves, which, in the event of a fire in the forward or 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 14 months after the effective date of this AD, replace the water drain valves having part number (P/N) ABS0341-2-01 in the forward and aft cargo doors with new valves that close at a lower differential pressure having P/N ABS0341-2-02, by doing all of the applicable actions specified in the Accomplishment Instructions of Airbus Service Bulletin A320-52-1124, Revision 01, dated May 31, 2005.
Actions done before the effective date of this AD in accordance with Airbus Service Bulletin A320-52-1124, May 6, 2004, are 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.
