Every aircraft seller discovers the same thing, always too late: at sale, the aircraft is not worth what it is — it is worth what the records prove it to be.
Two identical aircraft, same hours, same real mechanical condition. One has a complete, continuous, verifiable history; the other has "almost everything, just need to locate a few things." The first sells fast, at the asking price. The second becomes a negotiation — and every paperwork gap is a discount the buyer applies, rightly so: when in doubt, the risk is priced against the seller.
The good news in disguise: preparing for sale is, 90% of the time, the same recordkeeping discipline a well-managed operation should already have. Whoever operates right is preparing the sale every day, at no additional cost.
What the pre-buy will look for
The modern pre-buy inspection is less about opening cowlings and more about opening folders. The buyer's inspector's script:
Logbook continuity. Record gaps are the first alarm — a period with no entries raises the question the seller does not want: what happened here that was not written down? The intact, continuous logbook without erasures is the backbone of the dossier.
The exact state of hours and cycles. Airframe, engines, propellers, life-limited components — with the math closing between logbook, maintenance records and tracking. Divergence between sources is a certain discount: the buyer assumes the worst number.
The airworthiness directives. Not the statement "everything is complied with" — the complete list with method and evidence of compliance, one by one. It is among the most laborious items to rebuild late and the simplest to keep up to date.
Damage and repair history. Damage history hides poorly and is charged dearly: a well-documented repair — with approval, method and release — is a technical fact; a repair discovered by the inspector without documentation is a price chasm. Documented transparency is the only strategy that works.
Parts traceability. Components with certified origin, installed via traceable work orders — the chain that links each relevant part to its certificate and to the intervention that installed it.
The operation's past life. Under which regime it flew, who maintained it, with what regularity — the aircraft that operated under strict control carries this as a value argument.
What drives the price down (beyond the obvious)
- The "I'll locate it": every document promised and not delivered on the spot erodes trust in the entire dossier;
- Dependence on memory: "the mechanic who took care of it knows" is not a record — it is the confession that the record does not exist;
- Divergent parallel controls: the owner's spreadsheet, the hangar notebook and the logbook telling three histories;
- The grounded aircraft: long periods of inactivity cost at resale — the informed buyer knows what inactivity does to an engine and seals, and a history showing regular activity sells better than low hours sitting idle;
- Small open items: the forgotten deferred item, the old discrepancy with no closure — signs of loose management that the inspector extrapolates to everything he cannot see.
The manager's checklist — ideally years ahead
- Close the technical state: exact hours and cycles per component, with the sources matching each other;
- Build the directives dossier: complete list, status, method and evidence for each;
- Consolidate the intervention history: every relevant WO locatable, with release and responsible person;
- Document what is found, before the buyer finds it: the known and documented problem can be negotiated; the one discovered in the pre-buy blows up the negotiation;
- Organize the ownership and compliance paperwork: registration, insurance, clarity about who operated and is answerable;
- Rehearse the pre-buy: ask your team for the buyer exercise — every question without a ready answer is an item on the action plan.
How Alis handles this
The platform's thesis is exactly this article's: the sale dossier should be a byproduct of the operation, not a six-month project.
- The electronic logbook builds continuity with no gaps, with signature and audit trail;
- The CTM keeps the exact state — hours, cycles, expirations, directives with evidence — permanently closed with the logbook, because it is born from it;
- The full history is exportable: when the pre-buy arrives, the answer to the inspector is a package of reports, not a week of hunting for paper.
The well-documented aircraft is worth more, sells faster and negotiates from strength. And the best time to start the dossier was when it arrived — the second best is today.
