## Discrepancy

(CAN) IT WAS FOUND THAT THE SHEET METAL SCREWS HOLDING THE TIP ON THE WING HAD ALL COME LOOSE. THE WING TIP THEN VIBRATED FOR A PERIOD OF TIME ,ELONGATING THE SCREW HOLES IN THE WING UNTIL ALL OF THE SCREWS FELL OUT AND THE WING TIP DEPARTED THE WING IN FLIGHT. THE PILOT DID NOT NOTICE ANYTHING ABNORMAL AND ONLY NOTICED IT WAS MISSING ON WALK AROUND. (TC NR 20070517007)
