EASA AD 26-081
Fire Protection – Pyrotechnical Cartridge – Inspection
Summary
EASA Airworthiness Directive PAD No. 26-081 is a proposed directive addressing fire protection inspections for pyrotechnical cartridges installed on Dassault Aviation Mystère-Falcon and Fan Jet Falcon aeroplanes. It applies to all serial numbers of Fan Jet Falcon, Mystère-Falcon 20-( )5 series, Mystère-Falcon 200, and 20 GF models. The directive mandates repetitive inspections and potential replacement of specific pyrotechnical cartridges to ensure fire extinguishing capability.
What Changed
This proposed directive supersedes EASA AD 2025-0245 and expands the scope to include additional affected pyrotechnical cartridge parts (referred to as affected part B) beyond those previously identified (affected part A). It introduces updated inspection requirements and corrective actions based on recent reports of defective cartridges, requiring inspections at specified intervals and replacement deadlines.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety issue that could compromise the fire extinguishing system in engines, Auxiliary Power Units, or rear compartments. Operators and maintenance organizations must ensure compliance to prevent potential damage to aircraft and injury to occupants. It also affects maintenance planning and parts management due to the inspection intervals and replacement timelines.
What To Do
Operators of affected Dassault Mystère-Falcon and Fan Jet Falcon aircraft must perform repetitive inspections of identified pyrotechnical cartridges within specified compliance times, not exceeding six months between inspections. Any discrepancies found require immediate replacement of the affected part with a serviceable one. Additionally, all affected parts must be replaced before 36 months from manufacturing or 30 months since first installation, whichever occurs first.
