IN EFFECT
14 G450 ADs in effect, newest first
Informational only. These are FAA airworthiness directives whose published applicability names this make and model. Whether an AD applies to a particular aircraft depends on its serial number, installed engines, propellers, parts and modifications, and some ADs listed here will not apply. This list is not the official AD record and not a compliance determination: confirm applicability and compliance against the FAA’s Dynamic Regulatory System and the aircraft’s records with a certificated mechanic or inspector. Covers ADs published in the Federal Register since 1995, through Oct 1, 2026; older ADs, and engine, propeller and appliance ADs that do not name the aircraft, are not included.

QUESTIONS
G450 AD questions
Source: FAA final rules under 14 CFR part 39, from the Federal Register. The FAA’s Dynamic Regulatory System holds the official list.
How many airworthiness directives apply to the G450?
16 FAA ADs published since 1995 name the Gulfstream G450's type certificate model (GIV-X) in their applicability. 14 are still in effect as far as the Federal Register shows; the others were superseded by a later AD or removed. How many apply to one aircraft depends on its serial number, equipment and modifications.
Which G450 ADs are recurring?
3 of the ADs in effect require actions that repeat, such as inspections at set intervals, until a terminating action is done. They are marked Recurring above. One-time ADs are complied with once, but the compliance record stays with the aircraft.
What is the latest G450 airworthiness directive?
AD 2023-08-03, effective Jun 20, 2023: Gulfstream Aerospace Corporation Airplanes. The list is refreshed from the Federal Register every weekday.
How do I know whether an AD applies to my G450?
Read the AD's applicability paragraph, shown with each AD on this page, against the aircraft's serial number and its installed engines, propellers, parts and modifications. A certificated mechanic or inspector makes the determination and records the method of compliance in the maintenance records. The FAA's Dynamic Regulatory System holds the official list of ADs.
Why are engine and propeller ADs missing?
This page lists ADs whose applicability names the Gulfstream G450 airframe, plus appliance ADs that list it among the aircraft they can be installed on. Engine and propeller ADs name the engine or propeller model rather than the aircraft, so check them by the installed engine and propeller models.
Every AD on your G450, tied to the logbook entry that closed it.
Radar reads every logbook page, typed or handwritten, and builds one searchable record per tail: times, inspections, ADs and components, each tied to the page it came from.
