## Discrepancy

(CAN) HORIZONTAL STAB SPAR FOUND CRACKED FROM CENTRE RELIEF HOLE (LIGHTNING HOLE) OUTWARD APPROXIMATELY 1/2 INCH. PART REPLACED WITH NEW UNIT. THIS PROBLEM IS PROBABLY DUE TO INAPPROPRIATE GROUND LANDING OF THE AIRCRAFT, I.E. USING STAB AS SURFACE TO PUSH ON TO MANOEUVRE AIRCRAFT NOSE.
