What was found
I DEPARTED RW 14 AT APPROXIMATELY 8 AM LOCAL TIME @ KDTS. IN THE CLIMB, I ATTEMPTED TO RETRACT THE LANDING GEAR WITH NO SUCCESS (3 GREENS REMAINED LIT). I NOTIFIED EGLIN DEPARTURE OF THE DIFFICULTY AND REQUESTED SOME TIME TO RESOLVE THE ISSUE. I RESET BOTH THE MOTOR AND CONTROLLER CIRCUIT BREAKERS WITH NO SUCCESS. I REQUEST A CHANGE OF DESTINATION FROM KCNI TO KTLH. I THEN FLEW THE PLANE TO KTLH AND LANDED WITH NOT DIFFICULTIES. FLIGHTLINE GROUP MADE AN ADJUSTMENT TO THE LANDING GEAR (LH MLH) SAFETY SWITCH AND TEST FLEW THE PLANE.
