Cessna 210B N9578X accident near Bullhead City, Arizona

Probable cause

The failure of the landing gear actuator housing during landing for reasons that could not be determined based on the available evidence.

NTSB analysis

The pilot stated that, after takeoff, he heard a loud bang after he moved the landing gear handle to the "up" position. The landing gear indication lights did not illuminate. He cycled the landing gear handle, which had no effect. In addition, the flaps would not operate. During a low pass, the tower controller informed the pilot that the landing gear were in a transit position (not retracted, not locked down). The pilot attempted to execute the emergency gear extension procedure; however, the gear would not extend. During the landing, the gear completely collapsed, and the airplane slid to a stop on its belly and then tipped on its left side, which resulted in damage to the left horizontal stabilizer. The pilot reported that an airframe and powerplant mechanic visually examined the landing gear actuator and stated that the actuator housing had split, which resulted in the loss of hydraulic system pressure. However, no further examinations were conducted, and the reason for the housing failure could not be determined.
