The NTSB's narrative final · quoted from the NTSB record

The pilot said that during initial climb the engine lost power, and they crashed into trees. Examination of the airplane did not disclose any evidence of mechanical malfunction with the engine or the airplane. The three passengers said they did not see the pilot complete a weight and balance, neither did he ask them what their weights were, nor did he weigh their baggage. When their actual weights and baggage were computed, the airplane was 233 pounds over its maximum takeoff gross weight 2,500 pounds. One of the occupants said that he heard the stall warning horn just before the airplane struck the trees.
