SUPPLEMENTARY INFORMATION:
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued a series of ADs, the most recent being EASA AD 2021
0185R1, dated August 11, 2021 EASA
AD 20210185R1, to correct an unsafe condition for Umlaut Engineering GmbH, formerly P3 Engineering GmbH, fire extinguishers, having part number P/N P3APP003010A, P/N
P3APP003010B, or P/N P3APP003010C.
EASA advises of a safety issue that has been reported on the affected fire extinguishers where certain environmental conditions may prohibit discharge of the fire extinguisher. An investigation has determined that prolonged exposure to high temperature conditions can dislodge the spindle in the fire extinguisher head, subsequently making the fire extinguisher inoperative. This condition, if not addressed, could prevent proper extinguishing of a fire in the cabin or cockpit, possibly resulting in damage to the aircraft and injury to the occupants.
Initially, EASA issued EASA AD
20210185, dated August 5, 2021 EASA
AD 20210185, which required repetitive inspections of each affected
