What to do
Operators of Falcon 7X aircraft with the affected SAFRAN oxygen mask must amend the applicable Aeroplane Flight Manual before the next flight after 2021-09-13 and inform flight crews accordingly. Installation of affected parts on aircraft without them is allowed only if the flight manual is concurrently updated. Compliance with these requirements is mandatory from the effective date.
Summary
EASA Airworthiness Directive 2021-0202R1 is an amendment addressing safety concerns on Dassault Aviation Falcon 7X aeroplanes related to the SAFRAN crew oxygen mask Part Number MLD40-45-005. It requires updating the Aeroplane Flight Manual to incorporate specific change projects to ensure the oxygen saver function is not activated due to manufacturing defects. This directive applies to all Falcon 7X aircraft, including those modified to Falcon 8X standards.
What changed
This revision corrects the definition of the affected oxygen mask part number initially misstated in the emergency AD 2021-0202-E. It maintains the requirement to amend the flight manual and clarifies compliance methods for aircraft with or without the affected part installed. The directive remains an interim measure pending further action.
Why it matters
This directive is critical for operators and maintenance teams to prevent potential oxygen supply blockage to flight crew during decompression or cockpit smoke/fire emergencies. Ensuring compliance protects crew safety and maintains regulatory airworthiness standards. It also guides proper documentation updates and part installations to avoid unsafe conditions.
