Inspection Check List for Amateur Built Aircraft

The following checklist was generated by M. K. Blalock, (D.A.R.) for use during my
inspection of Amateur Built aircraft. Feel free to print it out and share it with your friends. This is NOT an official source of information. Always contact your local FAA office for official information.

  This document has been developed by Kenny Blalock as a Designated
  Airworthiness Representatives (DARs) as a basic inspection guideline for certification of
  amateur-built aircraft. It is not intended to be all-inclusive for every variation of experimental
  amateur-built aircraft. But, it is general enough in scope to show that 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 and making
  a signed log book statement. The DAR issues the special airworthiness certificate for operating the amateur-built
  aircraft. The use of the following guide, you should be able to perform what amounts to an in-depth
  pre-flight that should reasonably assure that the aircraft will operate as intended.
