Narrative:
A Beechcraft 400 Beechjet corporate jet sustained substantial damage in a runway excursion accident at Macon Downtown Airport, GA (MAC).
Three people on board sustained minor injuries.
The plane left Charleston International Airport, SC about 09:20 on a flight to Macon, GA. The airplane landed at Macon on runway 28 within the first 1,000 feet and there was water visible on the runway. Maximum reverse thrust, braking, and ground spoilers were deployed; however, both pilots reported a "pulsation" in the brake system. The airplane departed the end of the runway, traveled into the grass, went down an embankment, across Ocmulgee East Blvd, and into the trees.

Runway 28 is a 4696 ft (1431 m) asphalt runway.

PROBABLE CAUSE: "The pilot's failure to maintain proper airspeed, which resulted in the airplane touching down too fast on the wet runway with inadequate runway remaining to stop and a subsequent runway overrun. Contributing to the landing overrun were the flight crewmembers' failure to correctly use the appropriate performance chart to calculate the runway required to stop on a contaminated runway and their general lack of proper crew resource management.
