We are adopting a new airworthiness directive (AD) for certain Kidde Graviner hand-operated fire extinguishers. This AD was prompted by a report that a fire extinguisher failed to operate when the activation lever was pressed. This AD requires modifying the affected fire extinguishers. We are issuing this AD to prevent fire extinguishers from failing to operate in the event of a fire, which could jeopardize occupants' safety and continuation of safe flight and landing.
Within 6 months after the effective date of this AD, modify all Kidde Graviner hand-operated fire extinguishers having part numbers 56412-001 (34H), 56411-001 (35H), and 56412-002 (38H), in accordance with the Accomplishment Instructions of Kidde Graviner Alert Service Bulletin A26-081, Revision 1, dated January 31, 2012.
