Alpha Aviation’s 3-point Diagonal Shoulder Harness STC kit for Cessna 150s and 152s has been approved by the FAA.
The STC, which uses OEM quality AmSafe restraint assemblies meeting TSO-C114, includes belt assemblies and hardware for the installation of 3-point diagonal shoulder harness restraints in the pilot and co-pilot positions, according to company officials.
Cessna 150, 150A, B, C, D and E aircraft will require this STC for the installation of nut plates to accommodate the addition of 3-point diagonal restraints, company officials note.
Cessna 150F, G, H, J and K have existing factory installed nutplates. The upgrade to 3-point diagonal Fixed Strap restraints does not require an STC as it is accomplished by minor change. The upgrade to 3-point diagonal inertial reel restraints will require this STC to accommodate the positioning of the inertial reels, officials explain.
