What happened
During the preflight inspection and following takeoff, the landing gear indications for the aircraft remained normal. However, upon arrival at the destination airport, the right main landing gear indication failed to illuminate when the pilot attempted to lower the gear.
The pilot contacted the control tower for assistance and was advised that the gear appeared to be in the down position. After switching indicator bulbs, the pilot determined that a faulty bulb was not the cause of the indication failure. Due to the amount of fuel remaining on board, the pilot made the decision to feather and shut down both engines during the final approach.
Following the engine shutdown, the aircraft struck a berm located short of the runway. The impact resulted in damage to the airplane.
The investigation
A Federal Aviation Administration inspector examined the wreckage and reported that the extent of the damage to the aircraft precluded further investigation into the landing gear system.
