Aviation Hangar Fire Safety Inspection Checklist [FREE PDF]

Aviation hangar fire safety is governed by NFPA 409 (Standard on Aircraft Hangars), FAA 14 CFR Part 139, and OSHA 29 CFR 1910.157, which collectively establish requirements for suppression systems, fuel handling, egress, and hot work controls. Non-compliance can result in certificate suspension, civil penalties, and catastrophic loss of aircraft and personnel. Regular structured inspections are essential to maintaining airworthiness facility standards and protecting both assets and lives.
