Amateur-built JA 30 Superstol N146BB accident near Clover, South Carolina

Probable cause

The separation of a spark plug lead, resulting in a partial loss of engine power and collision with trees.

NTSB analysis

The pilot reported that, during the initial takeoff, the airplane was not developing adequate lift and was not climbing as expected. He maneuvered to avoid trees at the end of the runway; however, the airplane collided with the trees and the pilot lost airplane control. The airplane came to rest in a wooded area and sustained substantial damage. Examination of the engine revealed adequate fuel for the flight. Further examination of the engine revealed that one of the spark plug leads became disconnected and there was no postaccident impact damage in this area. The separated spark plug lead most likely resulted in a partial loss of engine power during takeoff.
