Kidde portable fire extinguishers that have been determined to be faulty must be replaced in some 39,000 aircraft, according to a recent AD. The manufacturer said the units involved “do not represent a safety problem,” even though they do not comply with technical requirements. The affected extinguishers (P/N 898052 with S/Ns from V-432001 to W-389653 and built between 1995 and 2002) exceed the maximum allowable discharge time of 10 seconds.

Halon fire-extinguishing agents have been used for many years to protect valuable electronics, oil and gas production facilities, military systems, aircraft and other critical operations. The Army Corps of Engineers developed Halon (short for halogenated hydrocarbons) in 1948 as a less toxic but highly effective alternative to methyl bromide.
