Narrative:
While on a proficiency check flight both pilots attempted to perform a barrel roll (a prohibited aerobatics manoeuvre). The Beech struck the ground shortly before completion of the roll.

PROBABLE CAUSE: "The deliberate disregard for Federal Aviation Regulations, GP Express procedures, and prudent concern for safety by the two pilots in their decision to execute an aerobatic manoeuvre during a scheduled check ride flight, and the failure of GP Express management to establish and maintain a commitment to instill professionalism in their pilots consistent with the highest levels of safety necessary for an airline operating scheduled passenger service."
