The aircraft crashed short of runway 33 after hitting an ILS tower.
PROBABLE CAUSE: "A premature descent below a safe approach slope followed by a stall and loss of aircraft control. The reason for the premature descent could not be determined, but it was probably the result of: (1) A deliberate descent below the published minimum descent altitude to establish reference with the approach lights and make the landing, (2) a visual impairment or optical illusion created by the runway/approach lighting systems, and (3) downdrafts near the approach end of the runway."
