D. Safety Belts
Figure 3 shows the safety belt installation. Each seat has a fixed lap belt and an inertia sensitive shoulder strap. The lap belt has 2 straps. The outboard strap has an adjuster to tighten the belt in use. It also has a tongue to engage the buckle on the inboard belt. The inboard strap has a fixed length. The buckle has a red button at the outboard end to release the tongue of the outboard lap strap. Push the tongue into the end of the buckle to lock them together.
Bolts with washer plates and self-locking nuts attach each lap strap to the seat pan. You must remove the seat to remove the lap belt.
The shoulder strap attaches to an inertia reel. The inertia reel has a latch which senses acceleration. With the airplane flying straight and level, the inertia reel lets the shoulder strap pull out against a light spring. If the airplane is accelerated (for example in turbulence), the latch stops the shoulder strap from pulling out.
The inertia reel for the pilot’s safety belt is located on the fuselage wall behind the pilot’s seat. The strap passes up through a guide attached to the roll-bar just above the pilot’s shoulder and down to the tongue on the outboard lap strap. The end fitting on the shoulder strap hooks onto a stud on the tongue.
The inertia reel for the rear passenger's safety belt is located above and to the rear of the passengers. It is on the fuselage top-inner surface.
E. Fabric Wall Panels
Fabric wall panels bond to the inside of the fuselage shell. Each front panel has a map pocket.
F. Instrument Panel Cover
A GFRP cover goes over the instrument panel. Screws attach the cover to the instrument panel. The instrument panel cover has a defrost manifold. Two hoses connect the defrost manifold to the cabin heating system. The manifold supplies warm air to the front of the canopy to prevent misting.
G. Center Console Panel
A GFRP panel goes between the rear wall of the floor panel and the front face of the front main bulkhead. The center console panel covers the trim mechanism. It also seals the gap between the pilots' seats.
