Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The plt reported a normal takeoff was made with 1300 RPM. At liftoff a small amount of black smoke emitted from both exhaust stacks and the RPM dropped to 1250. After clearing the rwy, more black smoke emitted and the RPM dropped to 1200. The plt cleared two 40 foot tall trees at the end of the rwy and made a hard landing in a field beyond the trees. Investigation disclosed the float from the zenith carburetor had 17 veritcal lines on the outside diameter and cracks. The float was fuel saturated.
