What to do
Operators of Falcon 7X aeroplanes must inspect affected crew oxygen mask stowage boxes within 5 flight cycles from 27 January 2021, following Dassault Service Bulletin 7X-570 instructions. Any discrepancies found must be corrected before the next flight. Additionally, from the effective date, installation of affected parts requires passing an operational test before the next flight.
Summary
EASA Airworthiness Directive 2021-0036-E is an emergency directive addressing the inspection of crew oxygen mask stowage boxes on Dassault Aviation Falcon 7X aeroplanes, including those modified to Falcon 8X standards. It applies to all serial numbers and focuses on parts with Part Number CSD30-005-X-X. The directive mandates inspection and possible corrective actions to ensure the oxygen supply system's integrity.
What changed
This new emergency airworthiness directive introduces a one-time inspection requirement for affected crew oxygen mask stowage boxes due to reported deviations in assembly and overhaul processes. It also establishes conditions for the installation and operational testing of these parts to prevent oxygen flow blockage. No previous directives are superseded by this AD.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk that could lead to oxygen supply blockage to cockpit crew masks, potentially causing hypoxia and loss of consciousness during critical flight conditions. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and crew safety. Failure to comply could result in unsafe flight operations and regulatory non-compliance.
