What happened
During an approach to the airfield, the pilot encountered heavy haze that significantly limited visibility. Due to the aircraft being at an excessive altitude and speed on the final approach, the decision was made to perform a go-around.
During the subsequent second approach, the landing gear was not deployed. The pilot later indicated that he believed the gear had already been extended prior to the second attempt. As a result, the aircraft type (unspecified) impacted the runway with the landing gear in the retracted position.
Upon touchdown, the aircraft slid for roughly 3,000 feet along the runway surface. Following this excursion, a fire ignited near the root of the right wing. Efforts to suppress the flames using portable fire extinguishers were unsuccessful. Despite the intensity of the fire, zero fatalities were reported as both the pilot and the copilot successfully evacuated the wreckage.
Findings
Investigations into the incident highlighted that the crew did not remember the process of retracting the gear during the initial approach. The primary factor contributing to the accident was the pilot's failure to verify the gear position during the second approach, driven by the mistaken belief that the gear was already down.
