Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2025-15-04, which applies to all Gulfstream Aerospace LP Model G150 airplanes. AD 2025-15-04 requires revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation. Since the FAA issued AD 2025-15-04, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require actions in AD 2025-15-04 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
