Narrative:
After takeoff, during gear retraction, it was evident that the nose gear remained down and locked. The decision was made to return to the departure airport for repairs. This necessitated dumping fuel. We were vectored to an unpopulated area dumped and at 10000 ft MSL, to our maximum gross landing weight. We returned to the field with the emergency equipment standing by, a normal landing was made. After inspection and securing the nose gear by my company's maintenance personnel, we taxied to the gate. After shut down we noticed the fuel panel was retarded to normal burn confign, causing a fuel imbalance that was barely within our operating manual's limitations. My flight engineer was a very experienced aviator, however, new to the company and airline flying. In the future, I will monitor all parts of all unusual procedures from beginning to end, as the last step is certainly as important as the first.

Title: RETURN LAND SITUATION SET UP AFTER ACR LGT UNABLE TO GET IT'S NOSE GEAR UNLOCKED AND INTO THE RETRACT POS.
Narrative: AFTER TKOF, DURING GEAR RETRACTION, IT WAS EVIDENT THAT THE NOSE GEAR REMAINED DOWN AND LOCKED. THE DECISION WAS MADE TO RETURN TO THE DEP ARPT FOR REPAIRS. THIS NECESSITATED DUMPING FUEL. WE WERE VECTORED TO AN UNPOPULATED AREA DUMPED AND AT 10000 FT MSL, TO OUR MAX GROSS LNDG WT. WE RETURNED TO THE FIELD WITH THE EMER EQUIP STANDING BY, A NORMAL LNDG WAS MADE. AFTER INSPECTION AND SECURING THE NOSE GEAR BY MY COMPANY'S MAINT PERSONNEL, WE TAXIED TO THE GATE. AFTER SHUT DOWN WE NOTICED THE FUEL PANEL WAS RETARDED TO NORMAL BURN CONFIGN, CAUSING A FUEL IMBALANCE THAT WAS BARELY WITHIN OUR OPERATING MANUAL'S LIMITATIONS. MY FLT ENGINEER WAS A VERY EXPERIENCED AVIATOR, HOWEVER, NEW TO THE COMPANY AND AIRLINE FLYING. IN THE FUTURE, I WILL MONITOR ALL PARTS OF ALL UNUSUAL PROCS FROM BEGINNING TO END, AS THE LAST STEP IS CERTAINLY AS IMPORTANT AS THE FIRST.
