BEECHCRAFT TC-12B

Full Narrative

On May 20, 2024, about 1008 eastern daylight time, a Beechcraft TC-12B airplane, N762MC, was substantially damaged when it was involved in an accident near Lehigh Acres, Florida. The pilot and the copilot were not injured. The airplane was operated as a public aircraft.
The purpose of the flight was to train a new copilot in the right cockpit seat for the Lee County, Florida Mosquito Control District (LCMCD). The flight instructor was in the left cockpit seat.
The LCMCD chief pilot reported the following. After an uneventful training mission, the copilot landed the airplane on runway 32 on or very near the centerline. He reduced power to idle, then lifted the throttles to move them over the gate into beta and reverse. At this point, the airplane quickly veered to the left. The flight instructor intervened and both pilots attempted to turn the airplane to the right and slow it down. Both pilots reported that the airplane seemed to be accelerating as it departed the left side of the runway. The flight instructor attempted to move the condition levers to cutoff; however, the airplane continued into a dry fish pond that was about 5 ft deep. The left main and nose gear collapsed and the airplane came to a stop.

An inspector with the Federal Aviation Administration responded to the accident site and examined the wreckage. There was substantial damage to the left wing, the aft fuselage, and the areas around the nose and left main landing gear. Both propellers were damaged from ground contact.

The wreckage was retained for further examination.
