* Structural ATA chapters use FAA K-code change rate. Verb-based propensity is suppressed there because "REPAIRED" in the SDR text usually refers to the airframe being repaired around the part.

Airworthiness Directive activity

FAA / EASA public regulatory data

2airworthiness directives affecting this fleet — recurring compliance demand for the parts and shops that serve it

Most recent

FAA AD 2025-15-04effective Sep 10, 2025Mixed actions
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This AD was prompted by a determination that a new airworthiness limitation is necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation. The FAA is issuing this AD to address the unsafe condition on these products.
FAA AD 2022-21-16effective Dec 21, 2022Mixed actions
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This AD was prompted by reports that wing flap fairing debonding and corrosion were discovered at certain areas of the lower skin on both wings. This AD requires an inspection for corrosion in certain areas of the wing skin fairings, additional inspections if necessary, resealing the fairings with new fillet seal, and applicable corrective actions, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Directives linked to this airframe family in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) across the fleet; inspection directives are not replacement directives, and none of this is a prediction that any part will fail.
