Analysis

The plt related that the acft was not performing well from the initial takeoff roll. Since he had only previously flown the acft in winter months & the temp was quite warm, he thought the lack of performance was due to the temp. He stayed in the traffic pattern & made a touch-&-go landing. He did not use the carb heat since he thought the air was not conducive to carb ice. After the touch-&-go, the eng was even more sluggish. On downwind, he noticed an indication of zero oil pressure & elected to turn directly to the rwy for an immediate landing. He decided not to extend the gear so as to extend his glide & minimize damage. Subsequently, he contacted the ground, left wing 1st, while trying to align the acft with the rwy. An exam of the eng revealed no indication of internal failure. Aprx 2 qts of oil were found in the eng & an undetermined amount had drained out at the crash site. The temp & dew point were 80 & 50 deg. According to icing probability charts carb icing was possible at or below rated power. Automotive fuel was used.
