Airframes Unlimited SS-2 Trainer

The Airframes Unlimited SS-2 Trainer is an American powered parachute that was designed and produced by Airframes Unlimited of Athens, Texas for the training role. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction.

The SS-2 Trainer was introduced in 2003 and production had ended by the time the company went out of business in 2014.

Design and development
The SS-2 Trainer was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a parachute-style wing, two-seats-in-side-by-side configuration, tricycle landing gear and a single 64 hp Rotax 582 engine in pusher configuration. The 50 hp Rotax 503 engine was optional, as was a single seat configuration.

The aircraft carriage is built from welded 4130 steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates spring rod suspension.

The aircraft has an empty weight of 375 lb and a gross weight of 827 lb, giving a useful load of 452 lb. With full fuel of 10 u.s.gal the payload for crew and baggage is 392 lb.
