Summary

On July 11, 2007, a Johnson F11C-2PJ (N442PJ) was involved in an accident near Deming, NM. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: Total failure of the top engine mount bolts and subsequent engine separation from the airframe.

The pilot said he had made a conventional 3-point landing. The airplane had rolled about 75 to 100 feet when the "engine sagged from the right front and rolled underneath [the airplane]." The pilot thought he had run over something on the runway, but he had actually "bounced over the engine." The airplane nosed over and slid to a stop. The pilot said the two top bolts and welds on the homemade engine mount had broken and the engine separated from the airframe because it had not been "adjusted for the weight of the Jacobs engine." The airplane had accumulated 16 hours of a 40-hour test phase.

This accident is documented in NTSB report DEN07CA118. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N442PJ.
