Boeing has advised all operators of 787s to inspect their airplanes for “improperly configured” engine fire extinguisher bottles following discoveries by Japan’s All Nippon Airways and Japan Airlines of a problem in a total of four Dreamliners.
Kidde Aerospace and Defense, a Hamilton Sundstrand business unit, won a contract from Commercial Aviation Corporation of China (Comac) to provide the fire and overheat protection for the new C919 airliner.
The manufacturer of portable halon fire extinguishers targeted for mandatory replacement said the units involved “do not represent a safety problem,” even though they are not in compliance with technical requirements. In a proposed AD, the FAA is calling for the removal of some 39,000 of the extinguishers due to improper crimping of the units’ siphon tubes.
Nearly 40,000 Kidde Aerospace halon fire extinguishers will have to be removed from service, under a proposed airworthiness directive. The FAA said the discharge time of the handheld units (part number 898052 and serial number of W-389653 or lower in units built between 1995 and 2002) exceeds the maximum allowable discharge time due to an allegedly crimped siphon tube.
Lufthansa has selected Hamilton Sundstrand, a United Technologies company, to supply its APS 3200 auxiliary power unit (APU) for 30 new single-aisle Airbus aircraft. The company has also recently delivered the first production-configuration secondary electric power distribution center (SEPDC) chassis assembly for the Airbus A400M military airlifter.
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.
