What are FAA Form 337s and 8130s and why do I need them?
While we are not in the business of providing management or maintenance advice, we get this question often and wanted to provide a description of these forms. Please use this for informative purposes only. Do not rely on this information to be up to date or accurate.
In this option for our ScanScription customers (standard for Premium ScanScription customers) we order the FAA Form 337s from the FAA and put them in a separate tab in your binder. We also pull all the 8130s in your logbooks and place them in a separate tab in your binder. These sections are bookmarked in the PDF version of the binder as well.
FAA Form 337 is "MAJOR REPAIR & ALTERATION (Airframe, Powerplant, Propeller, or Appliance)" and provides aircraft owners and operators with a record of major repairs or alterations indicating details and approval. The FAA defines a "major alteration" as "an alteration not listed in the aircraft, aircraft engine, or propeller specifications that might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or that is not done according to accepted practices or cannot be done by elementary operations." The owner needs to record any major alterations on FAA Form 337 and forward a copy of the appropriately filled in form to his or her local FSDO within 48 hours after the approval for return to service.

FAA Form 8130 has three sub parts, 8130-3, 8130-6, and 8130-9. Form 8130-3 is the "Authroized Release Certificate, Airworthiness Approval Tag" and the FAA states
that the form "identifies a part or group of parts for export approval and conformity determination from production approval holders. It also serves as approval for return to service after maintenance or alteration by an authorized part 145 repair station, or a U.S. air carrier having an approved CAMP under parts 121 and 135." Therefore, owners operating under Part 135 will need to pay close attention to this form. Our service will provide you with backups and copies of your FAA Form 8130s that are available to us which is particularly useful because if lost, the FAA has this to say:
"If a copy of an FAA Form 8130-3 is requested, a file copy of the original form may be provided by an authorized person, if available." Note the last two key words: "if available."
Form 8130-6 is the "Application for U.S. Airworthiness Certificate" and, according to the FAA
, the 8130-6 "is solicited under the authority of 49 U.S.C. 44103 as implemented by 14 CFR Part 21. The purpose of this information is to evaluate an applicant’s application for a U.S. Airworthiness Certificate."
Form 8130-9 is the "Statement of Conformity" and is to be submitted to the FAA under the following circumstances
- "By the applicant for a type certificate or a supplemental type certificate at the time he presents an aircraft or parts thereof to the FAA for tests."
- "By the applicant for a type certificate or a supplemental type certificate for each engine or propeller submitted for type certification."
- "By the type certificate holder or licensee manufacturing products under a type certificate only, upon the initial transfer by him of the ownership of each product or upon application for the original issue of an aircraft airworthiness certificate, or an Airworthiness Approval Tag (FAA Form 8130-3)"
