## Discrepancy

AIRCRAFT CAME IN FOR AN ANNUAL INSPECTION, DAMAGE TO THE FLAPS WERE FOUND DURING ROUTINE INSPECTION PROCESS.  RT FLAP HAD CRACKS RADIATING OUT FROM RIVETS ON LOWER T/E SKIN, PLUS CRACKS RADIATING OUT FROM L/E SKIN, ON BOTTOM OF FLAP, IB OF MOUNTING BRACKET.  DAMAGE DESCRIBED WAS ON RT FLAP.  LT FLAP HAD SAME DAMAGE, ONLY LESS SEVERE.  THE PROBABLE CAUSE WAS SUSPECTED TO BE CAUSED FROM LOWERING THE FLAPS AT TOO HIGH AN AIRSPEED.  FLIGHT DEPARTMENT CHAIRMAN AGREED TO DISCUSS THIS POSSIBLE PROBLEM WITH THE OTHER FLIGHT INSTRUCTORS, SO THEYY CAN DISCUSS THE PROBLEM WITH THEIR STUDENTS.  (K)
