AD/SB Impact Review
Airworthiness Directive and Service Bulletin Impact Review
AD/SB Impact Review helps operators, lessors, MROs, and technical-records teams understand what an Airworthiness Directive or Service Bulletin means for a specific aircraft, component, records package, or transition event. The work starts with applicability, then checks the evidence that supports compliance status and the practical follow-up needed for the maintenance program or transaction.
What this supports
- AD applicability and compliance-status review for a specific aircraft or component
- Service Bulletin effectivity and embodiment evidence review
- Maintenance-program and inspection impact scoping
- Pre-purchase, induction, redelivery, and audit support
- Records package review where AD/SB status is disputed or unclear
The problem
An AD or SB question is rarely answered by the title of the directive or bulletin alone. Applicability can turn on model, serial number, configuration, modification status, part number, prior embodiment, or a maintenance-program revision. Records teams then have to prove what was done, when it was done, which method was used, and whether a recurring action remains open. If that evidence is not reconciled before a transaction, audit, or return, the issue becomes a commercial blocker.
What to send
- Aircraft type, serial number, registry, operator, and deadline
- The AD, SB, service letter, task, or finding being reviewed
- Current AD/SB status report and maintenance-program reference
- Accomplishment records, task cards, release certificates, and modification evidence
- Any redacted data-room sample or discrepancy list already prepared
How the review works
Confirm the applicability question
Define the aircraft, component, configuration, jurisdiction, and event driving the review so the team is not answering a generic AD/SB question.
Trace status to evidence
Compare the status report against source records: accomplishment entries, task cards, modification records, release paperwork, and recurring-action tracking.
Separate records gaps from work gaps
Identify whether the issue is missing evidence, conflicting evidence, uncertain applicability, or work that may still need to be planned.
Map the next step
Produce a finding list and closure path that can support a records team, maintenance planner, engineering reviewer, buyer, lessor, or MRO handover.
Limits
This review organizes the applicability question and the supporting records. It does not issue an airworthiness determination, approve an alternative method of compliance, replace the certificate holder's responsibilities, or guarantee that an authority, buyer, lessor, or receiving operator will accept the package.
Who uses this
The output is used by technical records, maintenance planning, engineering, quality, asset management, buyer representatives, and MRO project teams that need an AD/SB position they can explain with evidence.
Next step
Talk through the scope.
Send the aircraft, deadline, and current obstacle. We will use the first conversation to understand the work, the evidence involved, and the right next step. You can include a redacted sample if helpful.
