What to do
Operators of BAe ATP aircraft must complete the overhaul and inspection tasks outlined in SB ATP-35-004 within 12 months from the effective date of 30 June 2022. This includes overhauling the oxygen mask regulator, testing and isolating faults in the harness, mask, microphone assemblies, supply hose, and radio cord assembly, and replacing parts as necessary. Compliance with these actions is mandatory unless previously accomplished.
Summary
The Civil Aviation Authority Airworthiness Directive G-2022-0013 addresses the overhaul requirements for crew oxygen masks on BAe ATP aeroplanes. It specifically targets the MC10 Series Crew Oxygen Mask, mandating inspection and maintenance tasks to ensure continued airworthiness. This directive applies to all manufacturer serial numbers of the BAe ATP aircraft.
What changed
This new Airworthiness Directive introduces a previously missing overhaul task for the MC10 Series Crew Oxygen Mask, including the oxygen mask regulator, pressure reducing valve, and bottle assembly hydrostatic test. It requires operators to perform inspections, fault isolation, and part replacements as detailed in BAE Systems Service Bulletin SB ATP-35-004. The directive fills a gap in the Maintenance Planning Document for the MC10 mask variant.
Why it matters
This directive is critical to prevent potential failure of emergency oxygen equipment, which could jeopardize pilot safety during emergencies. Aviation professionals must ensure compliance to mitigate risks associated with oxygen mask malfunction. Maintenance and compliance teams need to update their procedures to include these overhaul tasks to maintain regulatory conformity and aircraft safety.
