Plain English Summary

3/10 complexity

This Airworthiness Directive requires operators of Turbomeca Arriel 1 series turboshaft engines to inspect the tee coupling at the start electro valve for looseness and to ensure correct assembly, following Turbomeca Alert Service Bulletin A292 73 0251 (rev 2 or later), within one month of the AD becoming effective. The stated purpose is to address observed fuel leaks that could cause fire, power loss or uncommanded in‑flight shutdown. Compliance costs and actions fall to engine operators; the AD relies on the manufacturer’s ASB for the technical procedure.
