IADA Broker Practice Exam

FAA Form 337 is used to document major repairs or alterations and must be approved by the FAA before those changes are added to the aircraft’s records. The submission goes to the local FAA office that has jurisdiction over the aircraft’s home base or where the work is performed—the Flight Standard District Office. This office is responsible for airworthiness and maintenance oversight, so it reviews the proposed modification, ensures it meets applicable regulations, and records the approval in the aircraft’s maintenance history. The other agencies listed don’t handle this kind of maintenance documentation: the NTSB conducts accident investigations, the Department of Transportation is the broader parent agency, and the FCC handles communications equipment, not airframe modifications.
