CAA AIRWORTHINESS DIRECTIVE 007-11-97
APPLICABILITY First Technology Fire and Safety spherical type toilet compartment fire extinguishers Halon 1211 and 1301 between Serial Nos 7967 and 10356 inclusive.
SUBJECT - DESCRIPTION Fire Protection – Toilet compartment fire extinguishers.
COMPLIANCE - REQUIREMENT (SUMMARY) Compliance is required with First Technology Fire and Safety Service Bulletin 26-110 within 3 months from the date of the bulletin which is November 1997. The Service Bulletin requires the checking of the overall weight of the fire extinguisher mentioned on the production label. If the fire extinguisher is outside of the weight on the label it must be replaced with a new unit manufactured outside of the affected Serial No range. This action is required because at Serial No 7967 a manufacturing change was introduced for reasons of productivity improvement. The process change resulted in a leakage problem at the eutectic tip.
