Plain English Summary

1/10 complexity

This is an Airworthiness Directive — a mandatory safety order issued by the Civil Aviation Safety Authority (CASA) for aircraft.

Who it affects: Owners and operators of Gulfstream AA-5 series aeroplanes (also sold as Grumman American or American Aviation AA-5) with serial numbers 0002 through 0045.

What it requires: These aircraft must have their fuel tank vent lines modified according to the technical instructions in American Aviation Service Bulletin No. 128. This modification prevents fuel system problems such as dangerous pressure build-ups or leaks.

When it must be done: Before the aircraft can be issued a Certificate of Airworthiness (the official safety certificate required to fly legally).

Why it matters: Fuel tank vents are essential for safe fuel flow. This directive ensures these specific early-production aircraft meet critical safety standards before returning to or entering service.
