INERTIA REEL (P/N d73766) - Serviceable

The d73766 is an inertia reel assembly for aircraft shoulder-harness restraint systems. This component automatically retracts webbing during normal flight operations while locking instantly under rapid deceleration or impact conditions. Mounted within seat restraint assemblies, the reel allows pilot and passenger movement during cruise but engages the locking mechanism during emergency deceleration events.

The d73766-002 variant provides the reel mechanism less straps, designed for integration into FAA TSO-C114 and TSO-C22g certified restraint systems. Installation and functional testing must follow the applicable aircraft maintenance manual or supplemental type certificate (STC) instructions for proper operation and airworthiness compliance.
