What to do
Operators of affected Falcon 7X aeroplanes must perform an inspection of the two electrical power feeders within 12 months or 800 flight hours from 11 May 2022, whichever occurs first. If damage or clearance issues are found, corrective repairs and modifications to the forward lavatory bulkhead must be completed before the next flight. Additionally, clearance measurements must be repeated within 96 months or 4,000 flight cycles, with further actions as specified.
Summary
EASA Airworthiness Directive 2022-0073 is an airworthiness directive addressing electrical power load distribution issues on Dassault Aviation Falcon 7X aeroplanes, including those modified to Falcon 8X standard in production. The directive targets the right-hand front Secondary Power Distribution Box feeder to prevent smoke in the cockpit and loss of critical flight displays. It mandates inspection and possible modification of the electrical feeders and forward lavatory bulkhead to ensure safe operation.
What changed
This new airworthiness directive introduces a one-time inspection requirement for the right-hand front Secondary Power Distribution Box feeders on affected Falcon 7X aircraft. Depending on inspection results, corrective actions including repairs and modification of the forward lavatory bulkhead must be performed. It also sets specific measurement and clearance checks with defined corrective measures based on findings.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk involving potential smoke in the cockpit and loss of flight displays, which could significantly increase crew workload and risk occupant injury. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent in-flight system failures. The directive provides clear instructions to detect and mitigate electrical feeder deterioration before it leads to hazardous conditions.
