Plain English Summary

2/10 complexity

What this is: A mandatory safety order (called an Airworthiness Directive) for helicopter operators.

Who it affects: Anyone operating Eurocopter BO 105 helicopters that use cargo hooks with these specific part numbers:

S1609-2-105
S1609-2-105A
S1609-2-106
S1609-2-106A

What it requires: Operators must perform specific maintenance actions outlined in MBB Alert Service Bulletin No ASB-BO 105-80-107. This fixes a design flaw that could cause the cargo hook to release loads unexpectedly.

Deadline: The fix had to be completed before using the cargo hook system again, or by 22 February 1989 (whichever came first).

Why it matters: Prevents dangerous situations where underslung cargo (such as construction materials, firefighting buckets, or rescue equipment) could fall from the helicopter without warning, endangering people and property below.
