## Abstract

The FAA is superseding Airworthiness Directive (AD) 2025-15- 04, which applied to all Gulfstream Aerospace LP Model G150 airplanes. AD 2025-15-04 required 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 AD continues to require actions in AD 2025-15-04 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
