Plain English Summary

3/10 complexity

What it does: Requires operators of Mystère Falcon 50, 900 and 900EX aeroplanes fitted with certain Eros passenger oxygen masks to perform a functional test and verify the mask bag is Scott P/N 289‑601‑235. If the wrong bag or a failure is found, the seat must be placarded as unusable when supplemental oxygen is required and the discrepant mask replaced. This responds to discovered cracked bag–hose joints in systems fitted with Scott P/N 289‑801‑235.
