Probable cause

The total loss of engine power due to the failure of the number 5 and 6 connecting rods. A factor was the lack of suitable terrain for the forced landing.

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 pilot reported that he made one pass over the field he intended to spray. When he lined up to make the second pass, the 'engine shook fiercely and locked down.' A forced landing was performed to the field. During the landing roll, the airplane impacted a terrace and became airborne. The airplane landed again a 'short distance away and came to a stop.' During the impact with the terrace, the landing gear separated from the aircraft and the fuselage sustained structural damage. Postcrash examination of the engine by the operator revealed that the loss of engine power was attributed to the failure of the number 5 and 6 connecting rods which had penetrated the engine case.
