Incident Overview
A pilot executed a go-around during the landing phase after experiencing a severe vibration on short final. The decision to abort the landing was made as the airplane approached the runway. Following the go-around, the vibration persisted, prompting the pilot to conduct a precautionary landing with the landing gear retracted on runway 26.
Sequence of Events
The airplane touched down without landing gear, slid along the runway surface, departed the runway, and subsequently impacted terrain. The event resulted in substantial structural damage to the aircraft.
Damage Assessment
An inspector examined the aircraft and noted substantial damage to the external longerons on the lower fuselage and engine mounts. These components were significantly affected by the gear-up landing and subsequent slide.
Mechanical Inspection
Following a thorough examination, the inspector determined that there were no mechanical malfunctions or failures of either the airframe or the engine that would have precluded normal operation. The aircraft's systems were found to be functional prior to the incident.
Conclusion
The pilot's actions during the go-around and the subsequent precautionary landing were documented. The source does not provide any further details regarding the cause of the vibration or other contributing factors.
