## Analysis

AT THE CONCLUSION OF A CROSS COUNTRY BUSINESS FLT, PLT INITIATED A STRAIGHT IN APPROACH AFTER MONITORING THE WIND CONDITIONS BY OBSERVING A FLAG, WHICH HE REPORTED AS 'LIMP.' PLT REPORTED THAT TOUCHDOWN OCCURRED AT '50 KNOTS' FOLLOWING A FULL FLAP APPROACH AT :'60 KNOTS.' AFTER A SHORT GROUND ROLL, PLT SAID THE ACFT 'FLOATED OFF THE RUNWAY' AND HE ADDED A SMALL AMOUNT OF PWR TO CUSHION THE NEXT TOUCHDOWN. PLT STATED THAT THE ACFT THEN DRIFTED OFF THE LEFT SIDE OF THE RUNWAY IN A WINGS LEVEL ATTITUDE AND HE INITIATED A GO-AROUND WITH THE ADDITION OF FULL POWER. PLT SAID HE BEGAN A SHALLOW RIGHT TURN TO MOVE BACK OVER THE RUNWAY AND THE ACFT CONTINUED TO BANK TO THE RIGHT UNTIL IMPACT WITH THE GROUND DESPITE FULL CONTROL APPLICATION IN THE APPOSITE DIRECTION. EXAMINATION OF THE WRECKAGE FAILED TO REVEAL ANY PROBLEM WITH THE CONTROL SYSTEM.
