The helicopter was lost as reported but the landing gear configuration was Skids at the time of the accident. Sun used the Wheeled Landing Gear for a few months on a trial basis. Normal operation only. The gear performed very well. As a side note, after the gear was returned to Bell it was discovered that the Aft Crosstube was installed backwards by the manurfactor. This may have affected performance for a high speed run-on landing Sun Co. Inc. only performed Normal Operations, No Experimental Operations.
