After the deal closes
Post-acquisition aircraft records baseline
A post-acquisition baseline turns the records inherited at closing into a verified starting point the new owner can operate and re-trade from. It is run by or for the buyer once title has transferred, before the aircraft enters its new maintenance program. It fixes time and cycle status, AD and SB position, life-limited part standing, and the installed configuration as of the handover date. You receive a dated baseline package, a residual-gap list carried over from diligence, and a reconciled status view the owner can maintain.
When this review is needed
- Title has just transferred and the buyer needs one dated record of what was actually acquired.
- Diligence closed under a deadline and residual gaps were accepted into the deal.
- The aircraft is moving onto a new owner's maintenance program and the entry status must be fixed first.
- The asset will be re-leased or re-sold and the next counterparty will price against this starting point.
The problem
Closing happens against status lists and a redacted data room, not a settled baseline. Once the keys change hands, the buyer owns whatever the records actually say, and the accepted diligence gaps blur into day-one operating status. Without a fixed snapshot, every later question about time, cycles, or configuration reopens the whole transaction.
What gets reviewed
- Total time in service and cycles fixed as of the handover date
- AD compliance position carried forward from the closing data room
- Service Bulletin and modification status with effectivity for this serial number
- Life-limited part standing and remaining life at acquisition
- Installed configuration against the type design and approved modifications
- Residual diligence gaps logged as open items on the new baseline
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- Time and cycle totals at handover agree across logbooks, status lists, and the bill of sale supporting records
- Each AD position carried into the baseline is supported by the accomplishment evidence delivered at closing
- LLP remaining life at acquisition traces to release documents rather than the tracking summary alone
- Installed configuration matches the modification and effectivity records for the serial number
- The residual-gap list reflects every item that diligence flagged and the deal accepted
Evidence normally required
- The closing data room and any agreed records standard from the purchase agreement
- Current AD and SB status reports as delivered at handover
- LLP status list with supporting release certificates
- Airframe, engine, and APU logbooks or their digital equivalents
- The diligence findings list and the schedule of accepted exceptions
Common discrepancies
- Accepted diligence gaps that were never logged as open items after closing
- Time or cycle totals that disagree between the closing pack and the logbooks
- Configuration entries that do not reflect a modification embodied before the sale
- AD positions taken on trust at closing without the underlying accomplishment evidence
What is at stake
An owner operating without a fixed baseline cannot prove what changed on their watch versus what arrived broken. That ambiguity raises the cost of the next transaction and can put accepted diligence gaps back into dispute long after the seller has moved on.
How the work runs
Fix the handover date
Set the baseline date and pull every status figure to that point across logbooks and the closing pack.
Verify status and configuration
Confirm AD, SB, LLP, and configuration status against the source evidence delivered at closing.
Carry forward open items
Log accepted diligence gaps as tracked items so day-one status is honest.
Hand off a maintainable view
Deliver a reconciled baseline the owner's team can keep current.
What the buyer receives
- A dated baseline package fixing status, configuration, and traceability at handover
- A residual-gap list carried forward from diligence with each item's owner
- A reconciled status view the owner's records team can maintain going forward
Who uses the output
- Asset managers who need a fixed account of what the purchase actually delivered
- Records teams setting the entry status for the owner's maintenance program
- Transaction stakeholders who will price the next sale or lease against this snapshot
How the work fits into the transaction or program
The baseline picks up where diligence ends. It converts the closing data room into a dated starting point the owner operates from and the next counterparty can verify, and it feeds the entry status the new maintenance program is built on.
Start with a single asset
Start with a single tail and expand once the workflow is proven.
Aircraft-specific considerations
How much there is to fix at the baseline depends on the asset's age and trading history. A serial number that has passed through several operators carries more configuration drift and more places for status to have detached from source, so the snapshot is scoped to that history rather than a portfolio template.
Regulatory limits
The baseline records what the closing evidence supports as of the handover date. It does not issue an airworthiness determination, transfer or grant any approval, or substitute for the receiving operator's acceptance of the aircraft onto its program.
What this review does not cover
- Physical inspection or survey of the aircraft
- Renegotiation of the purchase agreement or its accepted exceptions
- Entry of the aircraft onto the new maintenance program itself
Specific to this review
- The baseline date is the dividing line for responsibility: it separates inherited gaps from anything the new owner introduces.
- Accepted diligence gaps are easy to lose after closing because attention shifts to operating the asset, so they are logged explicitly on the baseline.
- A fixed baseline lets the next sale or lease price against a known starting point instead of re-litigating the acquisition.

Frequently asked questions
How is this different from the diligence we already did before buying?
Diligence informs the decision to buy and the price. The baseline fixes what you actually own once the deal is closed, including the gaps you accepted, so you have a clean starting point to operate and re-trade from.
