Analysis

The pilot said that shortly after takeoff for an aerial application operation, the acft shuddered and settled back to the ground. After attaining about 10 or 15 feet of altitude; the acft bounced off a farm field and careened into some trees causing substantial damage. The surface temperature was 100 degrees f. and the wind was calm. The plt said he thought the weather conditons contributed to the accident.
