PDI Report › Aircraft pre-buy

Aircraft pre-buy inspection, planes and helicopters

Book a licensed aircraft engineer for a pre-buy inspection. Logbooks and ADs, airframe corrosion, engine compression and borescope, rotors, avionics and a test flight.

Book an aircraft check

An aircraft's value lives in its logbooks and its engine. Missing records, open airworthiness directives, corrosion or a tired engine can cost more than the purchase price. A licensed aircraft engineer (AME in India, A&P in the US) reviews the records and inspects the aircraft before you buy.

What can go wrong

How it works

1

Book in two minutes

Tell us what to check, the address and the date. Confirm your email with a 6-digit code.

2

A verified expert visits

A mechanic, engineer, inspector or surveyor near you calls, then checks every item on the list with you.

3

You get the report

A clear verdict, every issue with photos and notes, and what to ask the seller to fix before you sign.

The full checklist: 37 checks

The expert marks each check as OK, Issue or N/A, with notes and photos. Checks marked with a label only apply to that type.

Questions

Who does the inspection?

Only licensed aircraft engineers: AME in India or A&P mechanics in the US. We check every licence before approving the expert.

Do you cover helicopters?

Yes. Helicopters add checks for the main and tail rotors, gearboxes and chip detectors, and vibration.

Is this a replacement for an annual inspection?

No. A pre-buy inspection tells you what you are buying. The aircraft still needs its regular inspections to stay airworthy.

Check it before you sign for it

Available in India and the USA. We confirm the fee with you before the visit.
