Technical scrutiny

External Due Diligence

Independent technical and documentary review of an aircraft before you buy — records, airworthiness status, maintenance, title and traceability — conducted entirely on the buyer's side.

Why it matters

The seller's broker will not tell you what is wrong

By the time an aircraft is on the market, it comes wrapped in a persuasive story. Due diligence is how you test that story against the evidence — before the money moves and before problems become yours. A missing logbook, an open airworthiness directive, an undisclosed repair or a lien can each cost far more than the review that would have found it.

Because we act only for the buyer and never for the seller, our single job is to find what affects value or airworthiness and put it in front of you clearly, in time to act on it.

What we review

The documentary and technical scope

How we work

From scope to a report you can act on

1

Scope

We agree the depth of review against the aircraft, the deal timeline and your risk tolerance, and set what evidence we need from the seller.

2

Documentary review

We examine records, AD/SB status, maintenance and program data, title and traceability, flagging gaps and inconsistencies.

3

Inspection coordination

We frame and interpret the physical pre-purchase inspection, connecting what is found on the aircraft to what the records say.

4

Findings and support

You receive a clear risk report — what matters, what it means for value, and where it should shape price, conditions or walking away.

Independence. We are engaged by the buyer, paid by the buyer and accountable to the buyer. We have no interest in the deal closing — only in you knowing exactly what you are buying.

Common questions

Aircraft due diligence FAQ

What is aircraft due diligence?

It is the independent verification, before purchase, that an aircraft is what the seller says it is: that the records are complete and consistent, the airworthiness directives and service bulletins are addressed, the maintenance status is as claimed, and the title is clean and free of liens. It is the buyer's protection against inheriting hidden problems.

Is due diligence the same as a pre-purchase inspection?

They are complementary. A pre-purchase inspection is the physical examination of the aircraft, usually at a maintenance facility. Due diligence is the documentary and technical review — records, airworthiness, title and traceability — that frames the inspection and interprets what it finds. We work alongside the inspection, on the buyer's side.

Why does it matter who commissions the due diligence?

Because incentives differ. The seller's broker is paid to close the deal. Buyer-side due diligence has one job: to protect the buyer, and to surface anything that affects value or airworthiness before the money moves. We never represent the seller.

What is back-to-birth traceability?

For life-limited parts, it is the unbroken documentary trail proving each part's history and remaining life from manufacture to today. Gaps in that trail can ground a part or force early replacement, which directly affects value. Verifying it is a core part of due diligence.
