AD NUMBER: 2005-12-19
MANUFACTURER: Airbus SUBJECT: Airworthiness Directive 2005-12-19 SUMMARY: 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.
