Southern California Aircraft Appraisals | OakTree

Completing an appraisal report typically depends on the complexity of the report, the type of subject aircraft, the total time on the airframe, and other potential items that may require more time to research. Typically, between 1-2 work days for certified appraisals, and 2-3 work days for USPAP-compliant appraisals

The answer is yes. The Professional Aircraft Appraisers Organization dictates that all aircraft appraisals must be accompanied by an on-site inspection. This is a good thing because it adds credibility and professionalism to our reports. 

1. Please make available all airframe logbooks since the aircraft first went into

service in its factory-new state. Please advise ASAP if all logbooks are or will

not be available for inspection, or ifShop logbooks are kept at a different location.

2. Engine logbooks: If the engine/s are a product of a field or an Engine Shop

overhaul, we will need to have all engine logbooks since the engine/s were factory

new or remanufactured. If the engine/s are factory new or factory reman’d we will

only require the current logbook/s since the engine was purchased either new or

Factory Reman’d.

3. All FAA Form-337 forms reflecting STC installations, major repairs, avionics

installations, or airframe/engine/s modifications, etc..

4. Documentation reflecting the last aircraft exterior paint jobs, and aircraft interior

work completed. Note: Most of the time these two items will be reflected in the

airframe logbooks but not necessary.

5. Access to Aircraft’s FAA Airworthiness and Registration Certificates

6. If the airframe and/or engine/s are heavily modified we will need to know the

original costs of all modifications including installation for each item, since this info

directly effects the current value of the aircraft and/or engine values.

7. If your aircraft and/or engine/s/APU/s are on a progressive maintenance program, please make available, a current maintenance status report from your

maintenance provider, of which shows the last accomplished and forthcoming

inspection events for the airframe, engines and accessories, and any time/life limited items or parts.

8. If your aircraft is currently on any type of OEM maintenance service by the hour

(SBH) program for the airframe, components, parts, avionics and engines, we will require a copy of your service contract and OEM contact info to verify the plan/s are current and up-to-date, for valuation purposes.

“Certified” refers to the appraiser’s credentials. USPAP refers to the appraisal standard used to develop and report the value. A USPAP appraisal is designed to be defensible and audit-ready for high-reliance uses like lending, legal matters, and estates.
