Plain English Summary

2/10 complexity

This is a safety directive (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority for owners and operators of specific Gulfstream business jets (GII and GIIB models).

What it requires: Operators must perform regular functional checks of the takeoff warning system — the safety equipment that alerts pilots if the aircraft isn't properly configured for takeoff (for example, if flaps aren't set correctly or brakes are still engaged).

Why it matters: If this warning system is broken, pilots might attempt takeoff in an unsafe configuration without realizing it, potentially causing an accident.

What must be done:

Perform an initial functional check within 25 hours of flight time after 17 May 1990
Repeat the check every 150 hours of flight time thereafter
Follow the specific procedures outlined in Gulfstream Aerospace Customer Bulletin No. 388 (or later approved revisions)
