Plain English Summary

1/10 complexity

What this is: A mandatory safety modification (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority for specific Sikorsky S-76 helicopters.

Who it affects: Owners and operators of S-76 helicopters with serial numbers 76005 to 76007, 760001 to 760014, and 760016.

What it requires: You must modify the engine oil filler service door to add a backup method of securing it. This means installing an additional way to keep the door closed beyond the original latch or lock.

When to comply: Within 100 hours of flight time after 30 September 1979, unless you've already done the modification.

Why it matters: The manufacturer (Sikorsky) determined that the original single method of securing the oil filler door wasn't safe enough. If the door opens in flight, it could cause engine damage or failure. This directive ensures a failsafe mechanism exists to prevent that.
