Aircraft Accident/Incident Report

New Iberia, Louisiana 70560
Friday, November 20, 1998 8:30 CST

NTSB Narrative Summary Released at Completion of Accident

The airplane's engine experienced a catastrophic failure during cruise climb. The airplane impacted a tree and fence during the forced landing near a residential area. The airplane's maintenance records revealed that the engine had been overhauled on August 20, 1991, and had accumulated 1,423.49 hours since then. Examination of the engine revealed that the number 6 connecting rod had failed in 'overload' and was a 'secondary failure.' One of the connecting rod's bolt and nut assemblies was then examined. The nut was cut and split in the threaded area. The first two threads of the nut, adjacent to the contact surface, were found 'stripped.' Additionally, 'no scuff marks were observed' on the copper plating in the undamaged portion of the nut contact surface. It was determined that the two stripped threads were the result of the nut backing off during operation, and the lack of a scuff mark on the nut's contact surface was the result of it being improperly torqued during installation.

NTSB Probable Cause Narrative

The mechanic's failure to properly torque the connecting rod's bolt and nut during engine overhaul. A factor was the lack of suitable terrain for the forced landing.
