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.
Cessna 150L, M and 152 aircraft have existing factory installed nutplates. The replacement of the 3-point diagonal Fixed Strap diagonal restraints does not require an STC and can be accomplished by minor change. The upgrade to 3-point diagonal Inertial Reel equipped restraints will require this STC to accommodate the positioning of the reels.
The STC includes:
- Two shoulder harnesses;
- Fixed strap or inertial reel equipped;
- Two new lap belts with buckles and end fittings;
- All Required Hardware;
- 8130-3 Airworthiness Certificate and Certificate of Conformance;
- Detailed Installation Manual with Drawings; and
- Supplemental Type Certificate and STC Authorization.
The Fixed Strap STC Kit is $949 for two seats. The Inertial Reel Equipped STC Kit, which is expected to ship in mid-October, is $1,169 for two seats.
A Fixed Strap Replacement Shoulder and Lap Belt is $409 for one seat.
Stock colors are Black, Cruiser Grey and Fawn (Tan). Other colors are available at no additional cost.
I hope these are not the ‘one-shoulder’ diagonal belts that have torn up so many car & truck driver’s vertebae over the last few decades with full government approval. God save aviation from the FAA!
The proper term for the part in the seat belt assembly is “inertia reel” not inertial reel (no L).
Not to mention this: “New should harness STC” Should? In the title? Does no one proofread?
