First Technology Fire and Safety Ltd. Toilet Compartment Fire Extinguishers
First Technology Fire and Safety Ltd. toilet compartment fire extinguisher, identified by serial and model number in First Technology Fire and Safety Ltd. Service Bulletin (SB) No. 26-110, Revision 1, dated January 1998. These fire extinguishers are installed on but not limited to Airbus A320, A330, A340; British Aerospace Bae 146, Bombardier CL-600-2B19 (CRJ), Dornier 328 Embraer EMB 145, and all Fokker Series aircraft.
This amendment adopts a new airworthiness directive (AD) that is applicable to First Technology Fire and Safety Ltd. toilet compartment fire extinguishers. This amendment requires inspection of suspect fire extinguishers for leakage, and removal from service and replacement with serviceable parts if the extinguisher is found to be leaking. This amendment is prompted by reports of leakage at the fire extinguisher's eutectic tip. The leakage is the result of a design change. The actions specified by this AD are intended to prevent fire extinguisher failure due to leakage, which in the event of a toilet compartment fire could result in an uncontained fire and damage to the aircraft.
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.
