Analysis
Acquaintances of the plt rprtd he had performed maintenance to repair an inoperative airspeed indicator. He then took off on a test flt. A witness, who was a plt, rprtd the eng started to 'cut out' at about 200 to 300 ft AGL, the tail 'waggled a couple of times' & then the acft entered a spin & crashed in a nose down attitude. Two other witnesses rprtd there was an interruption of power before the acft crashed. However, the eng & forward part of the fuselage were badly damaged & no reason was found for a power loss. An exam of the airspeed indicator revealed it had ruptured & had been epoxied, but the rupture continued beyond the epoxy. The plt had a student certificate. He had 332 hrs of flt time in ultralights, but had logged only 3 hrs of dual flt time in powered acft & had only 2.3 hrs in this make & model.
