EAA Amateur-Built Aircraft Certification Inspection Guide

The information below is summarized from the EAA Amateur-Built Aircraft Certification Inspection Guide. Many of the links open the FAA Document Information page or the referenced Form.

This document has been developed for use by FAA Aviation Safety Inspectors (ASIs) and Designated Airworthiness Representatives (DARs) as a basic inspection guideline for certification of amateur-built aircraft. It is general enough to show the certification inspection is not to be a detailed Annual / 100 hour type inspection since the builder / applicant has already declared that the aircraft is “airworthy” by signing the application for the airworthiness certificate. The ASI / DAR issues the special airworthiness certificate for operating the amateur-built aircraft. The ASI / DAR, by use of the following guide, should be able to perform what amounts to an in-depth pre-flight that should reasonably assure that the aircraft will operate as intended.

Please visit the EAA Amateur-Built Aircraft Certification Inspection Guide for complete details.

Prior to the Aircraft Inspection

The aircraft must be registered before an airworthiness certificate can be issued. Verify the correct registration numbers are permanently marked in accordance with 14 CFR part 45, subpart C.

Confirm all paperwork is complete, and a Builder’s Log or similar type record of construction is available for review.

    • Registration: FAA Form AC 8050-1 must be in possession of the applicant.
    • Application for Airworthiness Certificate, FAA Form 8130-6 completed and signed.
    • Eligibility Statement Amateur-Built Aircraft, FAA Form 8130-12 (Notarized)
    • Aircraft Weight & Balance, to include most forward and most aft extreme loading calculated in accordance with FAA standards, as well as a first-flight calculation.
    • Log books for the airframe, the engine, and the propeller. A permanent record is needed for the airframe in order to have a place to record the issuance of the airworthiness certificate by the ASI or DAR. It is also recommended that separate records be provided for the engine and the propeller.
    • The aircraft must be 100% complete.
    • The engine should have been run for at least 1 hour. The run should have included operating in a nose high above stall attitude to ensure full fuel flow, and a full power run to verify and ensure maximum designed RPM is attained.
    • Verify that the Weight and Balance has been computed as outlined above. These calculations should be reviewed for accuracy by the inspector.

Aircraft Inspection

Definition: For the purpose of this inspection guide, “visually accessible” means that a section, area, part, system, etc., of the aircraft, can be viewed by the opening of a hatch/door or the removal of an inspection plate. It does not mean the removal of equipment, components, or the disassembly of any part of the aircraft that can not be performed by simple means.
