Rockwell International 112A N1401J accident near Clearwater, Florida

Probable cause

A total loss of engine power for reasons that could not be determined based on the available information.

NTSB analysis

According to the pilot, before departing on the personal flight, he added about 30 gallons of fuel to the airplane, which filled the left fuel tank completely and the right tank to about 7/8 full. He flew for about 20 minutes with the fuel selector on the left tank position. While preparing for landing, the pilot accomplished the before landing checklist, which included increasing the mixture to full rich, turning on the auxiliary fuel pump, and switching the fuel selector from the left tank position to the both position. He then reduced the throttle to slow the airplane and felt "slight resistance" on the throttle lever. About 10 seconds after switching the fuel selector, the airplane began to lose airspeed faster than anticipated. When he looked at the fuel flow indicator, the pilot saw it slowly transition from 8 gallons per hour to zero, and the engine subsequently lost all power. He moved the fuel selector back to the left fuel tank position, but the engine would not restart. During the forced landing, the airplane impacted a tree in the median of a 4-lane street before impacting and coming to rest in a stand of trees adjacent to the roadway.

Postaccident testing of the engine and fuel injection servo revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation. Although some debris was noted during the examination of the fuel injection servo, it was likely not enough to cause the engine to lose total power. Thus, the reason for the total loss of engine power could not be determined.
