Analysis

The home built acft was manufactured in 1975 & was built in Canada from the 1930 pietenpol aircamper design. The plt had flown the canadian registered acft to an antique fly-in. Traffic at the arpt required that only rwy 35 could be used. The plt waited from 1400 to 1700 PDT, for the wind to decrease, before taking off. Reportedly, he followed the posted left hand traffic pattern which took him over hills where he encountered turbulence & a down draft. Subsequently, the acft stalled & crashed in a steep descent. An examination of the engine revealed the spark plugs were carbon fouled with black, sooty deposits.
