AD compliance status
Gulfstream G650 airworthiness directive status records review
This review confirms that each entry on a Gulfstream G650's AD status list is supported by accomplishment evidence and the correct method of compliance for the tail. It is run for a lessor, operator, or manager assessing, transferring, or continuing to hold the aircraft, typically before a transaction, an owner handover, or a program move. It walks each directive's applicability and compliance position back to the record that closed it, and checks recurring ADs are being tracked. You receive a supported exception list, a source map from each AD to its evidence, and a closure plan for directives whose position is not yet supported.
When this review is needed
- A buyer needs the G650's AD position confirmed against accomplishment evidence before pricing.
- An owner handover is approaching and the incoming manager wants the compliance status verified.
- A recurring AD may not be tracked and no one has confirmed its next-due position.
- The status list was carried over between management arrangements and its basis is unchecked.
The problem
A G650's AD status list reads as a settled ledger, but each line is only as good as the accomplishment record behind it. On a managed business jet that has moved between management arrangements, a directive can be shown as complied while the record proving it sits in a prior manager's files, or a method-of-compliance choice can be asserted without the substantiation that a superseding revision now demands. Recurring directives are the harder case: the list can show the last accomplishment while nothing is actively tracking the next due point.
What gets reviewed
- Applicability of each directive confirmed against this serial number and its configuration
- Accomplishment evidence matched to every AD shown as complied
- Method of compliance recorded and consistent with the current revision of each directive
- Recurring ADs checked for active tracking and their next-due position
- Directives affecting modified or STC configuration reconciled with the modification status
- Superseded directives confirmed closed under the superseding revision, not the original

What gets validated
- Each AD shown as complied has accomplishment evidence that reconciles to the tail
- The recorded method of compliance matches the current revision of the directive
- Recurring ADs have a tracked next-due point, not just a last-accomplished date
- Applicability reflects this serial number and any modifications that change it
- Superseded directives are closed under the superseding revision with supporting evidence
Evidence normally required
- The current AD status list for the airframe, engines, and appliances
- Accomplishment records and work packages supporting complied directives
- Method-of-compliance documentation for each applicable AD
- The modification and STC status affecting AD applicability
- Recurring-AD tracking data and next-due schedules
Common discrepancies
- An AD shown as complied with no accomplishment record to support the position
- A recurring directive tracked by last accomplishment but with no next-due point in the program
- A method of compliance asserted against a revision the directive has since superseded
- An AD whose applicability changed with a modification that the status list never reflected
What is at stake
An AD shown as complied without accomplishment evidence forces the position to be reopened, and at a handover the incoming manager will not take the line on trust. A recurring directive that is not being tracked is a live continued-airworthiness gap that can ground the aircraft when the next due point passes unnoticed, and reconstructing accomplishment evidence after a change of management is far harder than confirming it while the record is still accessible.

How the work runs
Take the status list
Establish the current AD position for the airframe, engines, and appliances.
Match to evidence
Reconcile each complied directive to its accomplishment record and method of compliance.
Track the recurring ADs
Confirm every recurring directive has a tracked next-due point, not just a last date.
Resolve the exceptions
List unsupported and untracked directives with a path to close each.
What the buyer receives
- A supported exception list of directives whose position is not backed by evidence
- A source map linking each AD to its accomplishment and method-of-compliance records
- A closure plan for unsupported directives and recurring ADs that need reinstating in tracking
Who uses the output
- Records teams confirming the AD status list rests on accomplishment evidence
- Asset managers pricing the compliance position the records actually support
- Incoming management teams verifying the AD basis before assuming oversight
How the work fits into the transaction or program
AD status sits on top of the configuration the aircraft carries, because a modification or STC can change which directives apply. Reconciling the AD position after the modification status is settled means each directive's applicability is checked against a configuration already confirmed, and the reconciled AD status then feeds the owner handover and airworthiness-review evidence.
Aircraft-specific considerations
The G650 is a managed business jet that changes management arrangements over its life, and each change is a point where accomplishment evidence can be left behind with the prior manager. Its avionics and cabin configuration attract STCs that shift AD applicability, and owner-handover baselines are the moments when the compliance position is scrutinized most closely, so the review focuses on evidence continuity across management changes rather than a generic type-level check.
Jurisdiction-specific considerations
The FAA issues the ADs for the type, but an EASA operator applies the corresponding EASA directives, and a G650 moving between systems will have its AD position reassessed against the receiving authority's directive set. The review notes where a compliance position built to one authority's ADs has to be mapped onto the other's before a receiving operator relies on it.
Regulatory limits
The review reconciles the AD status against the accomplishment evidence and method of compliance on file. It does not determine compliance on an authority's behalf, accomplish or sign off any directive, or make an airworthiness determination on the aircraft.
What this review does not cover
- Accomplishing or signing off any airworthiness directive
- Determining compliance on a regulatory authority's behalf
- Any airworthiness ruling on the tail based on its AD position
Specific to this review
- Recurring ADs are the recurring failure mode: the list shows the last accomplishment while nothing is tracking the next due point.
- A change of management arrangement is where G650 accomplishment evidence most often separates from the status list it supports.
- An STC on the avionics or cabin can change AD applicability, so the modification status has to be read alongside the AD list, not after it.

Frequently asked questions
Why do recurring ADs get special attention?
A one-time AD is either done or not, but a recurring directive has to be flown continuously against its interval. If tracking dropped the next-due point at a change of management, the list can look complied while an interval quietly passes, which is a live grounding risk rather than a records gap.
