 This resulted in its being seriously underpowered; the 112 prototype was powered by a 180 hp (134 kW) Lycoming O-360 engine, this was replaced by a 200 hp (149 kW) IO-360 engine in production aircraft.Even with this engine there is widespread agreement that the aircraft was underpowered.Another annoyance was that the fibreglass composite doors did not fit well and tended to leak.
