## Discrepancy

THE RT FLAP FLEX DRIVE HOUSING FAILED AT THE SWAGED END OF THE HOUSING AT THE IB END.  ON SEPTEMBER 11, 2007 THIS AIRCRAFT HAD A SIMILAR EVENT WITH THE LT OB FLAP DRIVE WHICH ALLOWED THE FLEX DRIVE TO DISENGAGE FROM THE OB FLAP DRIVE CAUSING THE FLAPS TOP REMAIN AT 3 DEGREES POSITION AND PREVENTING FURTHER EXTENSION OR RETRACTION. WE OPERATE 2  AIRCRAFT AND THIS IS THE 4TH FAILURE OF THE FLEX DRIVE BETWEEN THE 2 AIRCRAFT.
