## Discrepancy

NOSE LANDING GEAR DOORS PARTIALLY OPEN DURING FLIGHT WITH GEAR RETRACTED. TEXTRON AVIATION INC. B300 EQUIPPED WITH TEXTRON AVIATION INC. EXTENDED NOSE (KIT 130-4050) AND EXTENDED NOSE EO/IR LIFT (KIT 130-4051). NOSE LANDING GEAR DOORS PARTIALLY OPEN DURING FLIGHT WITH THE EO/IR TURRET IN THE EXTENDED POSITION. THE DOORS REMAIN OPEN 1/2-1 INCHES WITH SLIGHT VIBRATION DUE TO AIRFLOW AROUND THE TURRET OF THE EXTENDED NOSE LIFT ASSEMBLY UNTIL THE TURRET IS RETRACTED. THIS WAS VERIFIED BY VIDEO RECORDING MADE BY AN EXTERNALLY MOUNTED CAMERA AFT OF THE GEAR DOORS. IN RESPONSE, THE NOSE GEAR DOOR RIGGING WAS CHECKED BY TEXTRON AVIATION INC. AND FOUND TO BE IN ACCORDANCE WITH TEXTRON AVIATION INC.  ICA P/N 130-590031-0658, CHAPTER 32-20-05 AND KIT 130-4050-0009/-0027 INSTALLATION INSTRUCTION ITEM 22. SUBSEQUENT FLIGHTS AFTER RIGGING CHECKS PRODUCE THE SAME RESULTS OF NOSE GEAR DOOR OPENING.
