Incident Overview
Following takeoff, the pilot heard a loud bang from the aircraft. Shortly thereafter, an unsafe landing gear indication appeared, and the pilot was unable to extend the right main landing gear. The pilot then initiated an emergency landing.
Emergency Landing and Aftermath
The airplane touched down on the runway with the right main landing gear only partially extended. During the landing roll, the aircraft veered to the right before coming to rest on the runway.
Post-Incident Examination
An examination of the landing gear extension system revealed that the actuator body was cracked and separated at the forward bolt hole. This separation prevented the main landing gear actuator piston from properly meshing with the sector gear, which precluded the landing gear from extending.
Fracture Analysis
Analysis of the fracture surface indicated that the failure was consistent with overload.
