Probable cause
The facility's designation of the taxiway for use by maintenance personnel to conduct high thrust tests without appropriate safeguards in place, which led to maintenance personnel conducting high-power, run-up thrust procedures across the active taxiway and resulted in the loss of directional control of a light, single-engine airplane on the taxiway when it encountered a sudden, unexpected blast of engine thrust.
