US-FAA14 CFR 91.108

Use of supplemental restraint systems

Read the official rule

This regulation governs the use of supplemental restraint systems (like safety harnesses) in aircraft, primarily for operations with doors open or removed—such as aerial photography, skydiving, or sightseeing flights.

Key requirements:

  • Normally, supplemental restraint systems cannot be used unless operating with doors open/removed
  • During taxi, takeoff, and landing, everyone must use standard seatbelts and shoulder harnesses
  • Once airborne, individuals may transition to supplemental restraint systems only with the pilot's authorization
  • The harness must secure around the torso, connect to FAA-approved airframe attachment points (not flightdeck locations), keep the person inside the aircraft, and have an easily accessible quick-release mechanism
  • Systems can be provided by the operator or individual user, but must fit properly based on sizing criteria
  • The pilot in command has final authority over system use and must ensure passengers are briefed on proper use and emergency procedures
  • A qualified person must properly connect the system to appropriately rated attachment points
