Category:Accident
Location:Nr. El Centro, CA -   United States of America
Phase: Initial climb
Nature:Private
Departure airport:Calexico, CA (CXL)
Destination airport:Whiteman Airpor, CA (WHP)
Investigating agency: NTSB
Narrative:
During the initial climb through 5,500 feet, the engine had a total loss of power. The pilot subsequently landed in an alfalfa field, during which the nose gear collapsed, and both wings sustained substantial damage. A postaccident examination of the engine revealed that the #2 through bolts and deck studs were loose, allowing the #2 bearing half to shift and cover the oil transfer tubes on the bearing support. This sequence resulted in the #2 main bearing failure due to oil starvation, and subsequent separation of the #2 connecting rod, which resulted in the loss of engine power. The airplane's #2 cylinder had been replaced 24 hours prior to the loss of engine power.





Probable Cause: The failure of maintenance personnel to properly secure the #2 cylinder through bolts. A contributing factor was the lack of suitable terrain for landing.
