EASA AD 2026-0158
Fire Protection – Pyrotechnical Cartridge – Inspection
Summary
EASA Airworthiness Directive 2026-0158 is an airworthiness directive addressing fire protection pyrotechnical cartridges installed on Dassault Aviation Mystère-Falcon and Fan Jet Falcon aeroplanes. It mandates repetitive inspections and potential replacement of specific pyrotechnical cartridge parts identified by part and batch numbers to ensure fire extinguishing capability. The directive applies to all serial numbers of Fan Jet Falcon, Mystère-Falcon 20-( )5 series, Mystère-Falcon 200, and 20 GF aeroplanes.
What Changed
EASA Airworthiness Directive 2026-0158 supersedes AD 2025-0245 and expands the scope of affected pyrotechnical cartridges to include additional part numbers (affected parts B) alongside the previously identified affected parts A. It introduces repetitive inspections for all affected parts and updates compliance requirements to address newly reported defective cartridges.
Why It Matters
This directive is critical for aviation professionals because defective pyrotechnical cartridges can compromise the aircraft's fire extinguishing systems, posing safety risks to the aircraft and occupants. Operators and maintenance organizations must ensure compliance to prevent potential fire hazards and maintain airworthiness. The directive also clarifies installation and replacement requirements to maintain continued safety.
What To Do
Operators of affected Dassault Mystère-Falcon and Fan Jet Falcon aeroplanes must perform initial and repetitive inspections of identified pyrotechnical cartridges within specified compliance times, replacing any defective parts before further flight. All affected parts must be replaced with serviceable parts within 36 months of manufacturing or 30 months since first installation. Installation of affected parts is only allowed if they pass inspection prior to flight.
