Set an evidence-based first-year cash plan before closing.
Start from reconciled status
Have the technical adviser prepare the relevant calendar and usage-based event picture from the actual records, aircraft configuration and intended annual use. Include unresolved findings, required inspections and confirmed program terms. The FAA's AD guidance makes applicability and compliance timing product-specific. A seller's phrase fresh inspection should not erase other events or replace the reviewed maintenance status.
Distinguish cash spending and reserves
List known work with expected timing and current quotes where available. Show hourly reserves as budgeting allocations, not automatically additional invoices. Determine which events are covered by a verified program and which are excluded. Avoid charging the budget for a program-covered event in full while also treating its program payments as the same cost, unless the actual agreement creates a separate obligation.
Work an illustrative credit example
Suppose a $60,000 seller credit is agreed for buyer-performed work estimated at $80,000. The acquisition model should reflect the credit in price or funds flow and retain the $80,000 expected expense, leaving an illustrative $20,000 economic gap before uncertainty. It should not show an $80,000 completed improvement merely because the credit was negotiated. Actual amounts and responsibilities come from the agreement and provider quote.
Stress-test timing and utilization
Model a near-term event arriving earlier, lower utilization spreading fixed costs across fewer hours and downtime requiring substitute travel. Keep assumptions explicit rather than promise a maintenance-free period. Have the operator and lender understand any accepted deferred work, and retain the final maintenance calendar with the owner handover. Update the plan when findings, use or provider terms change.
Working document to prepare
Build a first-year calendar with each verified event, trigger, estimated date, provider quote, program coverage, reserve treatment, seller credit and downtime assumption. Separate cash payments from transfers into a reserve account. Reconcile the calendar after inspection and technical acceptance. Retain the assumptions used for annual hours and aircraft condition, then update them during ownership so actual costs can be compared with a documented baseline rather than an untraceable hourly average.
Your next-step checklist
- Use actual calendar and usage status.
- Confirm program coverage and exclusions.
- Separate reserves from invoices.
- Reconcile credits without pretending work is complete.
