## Discrepancy

DURING CLIMB FOR A ROUTINE FLIGHT FROM KGVL TO MYAM, THE CREW REPORTED A "CNTL" CAS MESSAGE AFTER SELECTING LANDING GEAR TO THE UP POSITION.  THE CREW PERFORMED THE QRH PROCEDURE AND RECEIVED 3 GREEN DOWN-AND-LOCKED INDICATIONS AND MADE A DIVERSION TO KPDK WITH NO FURTHER INCIDENTS.  TECHNICIANS FOUND THE NOSE LANDING GEAR STRUT FAILED TO EXTEND FULLY AFTER TAKE-OFF, CAUSING THE NOSE GEAR NOT TO RETRACT INTO THE BAY FULLY.  THE TECHNICIANS REPLACED THE BARREL NUT, SCRAPER RING, AND ASSOCIATED SEALS IAW THE CMM 32-20-05.  FUNCTIONAL AND OPERATIONAL CHECKS WERE SATISFACTORY.
