Flight Conducted Under: Part 135: Air taxi & commuter - Non-scheduled

On April 30, 2022, about 1000 central daylight time, a Beech B-99 airplane, N699CZ, was substantially damaged when it was involved in an accident at the General Mitchell International Airport (MKE), Milwaukee, Wisconsin. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 135 on-demand air-cargo flight.

The flight originated from the Baraboo/Wisconsin Dells Regional Airport (DLL), Baraboo, Wisconsin, with MKE as the intended destination. As the airplane approached MKE the pilot was cleared by air traffic control (ATC) for the visual approach for runway 19R at MKE. He noted that the landing was “smooth given the weather conditions”, and he used normal braking to exit the runway. Upon entering the ramp area, the right landing gear “Green” light extinguished, and the “Red” gear handle light illuminated. The pilot glanced over by to the circuit breaker panel and the “Landing Gear Control” circuit breaker had tripped. After parking the airplane for refueling he notified his company maintenance control group about the issue and was advised to not reposition the airplane after refueling. The pilot waited about 20 minutes for weather to clear before exiting the airplane. As he was exiting the airplane, the right main landing gear collapsed and the airplane’s right wing struck the ground, resulting in substantial damage to the right wing.

Subsequent to the accident it was discovered that the drag leg support for the right landing gear had broken. Further examination by the operator determined that the same part on the left landing gear was fractured. The fractures in the left landing gear part were not detected visually or using dye penetrant inspection but were detected using an eddy current inspection.

The parts from both landing gear were retained for further examination.
