What this safety rule does

This Airworthiness Directive mandates that owners of specific Gulfstream business jets must permanently remove certain aircraft parts from service once they reach predetermined usage limits.

Who it affects

Owners and operators of Gulfstream II, Gulfstream IIB, and Gulfstream IV aircraft

The requirements

Identify "life-limited components" listed in Chapter 5, Section 5-4 of the aircraft's official Maintenance Manual
Retire (permanently remove from use) these parts when they reach their specified limits — typically measured in flight hours, flight cycles, or calendar time
Follow the specific limits set out in the manual applicable to your particular aircraft model

Why it matters This prevents catastrophic mechanical failures by ensuring critical components are replaced before they wear out. This version expands the safety requirement to also cover Gulfstream IV aircraft, which were not included in previous versions of the directive.
