Just because you are a "Test Pilot" doesn't mean that having a grand total of 30 minutes on type makes it wise to attempt to expand the crosswind envelope to 36 knots.
"D-CTRJ touched down in a strong crosswind. The pilot applied full left rudder but the aircraft yawed right. During the rollout, power was increased momentarily and aileron deflection was reversed from a ‘roll right’ to a ‘roll left’ sense. The aircraft rolled left, the right main landing gear lifted off the runway and the aircraft yawed into wind. The pilots could not regain control before the aircraft left the right side of the runway and ran onto the grass."
