| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that during climbout for an agricultural flight, about 75 feet above the runway, he heard a loud "pop," and the engine started to lose power. He dumped the 250 gallons of chemical that weighed about 2,000 pounds. The airplane continued to lose altitude, and the pilot executed a forced landing to a cotton field. A postimpact engine fire ensued, consuming the airplane. An examination of the engine revealed that the No. 2 cylinder exhaust rocker boss was cracked, which likely allowed oil to escape, which led to the loss of engine power and the subsequent fire.
Probable Cause: The loss of power due to the failure of the No. 2 exhaust valve and rocker boss during takeoff.
