What to do
Operators of affected Dassault Falcon aircraft must remove and replace any fire extinguisher percussion cartridge exceeding 10 years total life, with a grace period of up to six months for cartridges already beyond 9 years and 6 months as of 1 May 2019. They must also revise their approved Aircraft Maintenance Programme to incorporate the 10-year life limit and follow Dassault AMM tasks for cartridge removal and replacement.
Summary
EASA Airworthiness Directive 2019-0084 is an airworthiness directive addressing the fire extinguisher percussion cartridges installed on Dassault Aviation Mystère-Falcon 50, Mystère-Falcon 900, Falcon 900EX, Falcon 2000, and Falcon 2000EX aeroplanes. It establishes a life limit for these cartridges to ensure continued fire protection effectiveness. The directive applies to cartridges with part numbers 862700-00 and 862710-00.
What changed
This directive introduces a mandatory total life limit of 10 years for the affected fire extinguisher percussion cartridges, correcting a previous incorrect life limit of 12 years stated in the Dassault Maintenance Planning Document. It requires removal and replacement of cartridges exceeding this limit and mandates updates to the approved Aircraft Maintenance Programme to reflect this change.
Why it matters
The directive is critical for aviation professionals because exceeding the correct life limit on fire extinguisher percussion cartridges could compromise fire suppression capability, potentially leading to fire damage and occupant injury. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and regulatory conformity. It also impacts maintenance planning and record-keeping to track cartridge life accurately.
