Narrative

ON APCH TO HECTOR INTL ARPT WE ATTEMPTED TO LOWER THE LNDG GEAR. THE GEAR LIGHT INDICATOR DID NOT LIGHT TO SHOW A DOWN GEAR. WE TRIED TO CYCLE THE GEAR; THE GEAR-UP LIGHT INDICATOR WOULD NOT SHOW AN UP-GEAR. WE TRIED TO CYCLE THE GEAR MANUALLY AND PUMP IT DOWN; WE HAD NO SUCCESS. WITH FURTHER CONTACT WITH THE TWR; THEY SUGGESTED MAKING A LOW APCH ON RWY 13; TO FLY BY THE TWR SO THEY COULD OBSERVE THE GEAR IN A DOWN POS. THEY OBSERVED THAT WE HAD A MAIN GEAR IN A DOWN POS; BUT NO NOSE GEAR. THEY HAD US FLY IN A HOLDING PATTERN AND TRY DIFFERENT CYCLING. THEY CONTACTED MECH FROM FBO MAINT TO COME OUT AND SIT AT AN INTXN. WE DID SEVERAL FLY-BYS AND A LOW APCH SO HE COULD OBSERVE THE DOWN GEAR POS. BY CYCLING THE GEAR DOWN WITH THE PUMP; HE INDICATED WE HAD THE MAIN GEAR DOWN AND THE NOSE GEAR DOWN; BUT IT DID NOT APPEAR THAT THE NOSE GEAR WAS FAR ENOUGH FORWARD IN LOCKING POS. WE FLEW E OF FARGO IN A HOLDING PATTERN; TRYING DIFFERENT SUGGESTIONS FROM THE TWR; BUT TO NO AVAIL. WE FLEW FOR SEVERAL HRS; TRYING TO DECIDE WHAT TO DO AFTER OUR UNSUCCESSFUL ATTEMPTS TO LOWER THE GEAR. A FINAL DECISION WAS MADE TO LAND IN A GEAR-UP LNDG; RATHER THAN CHANCE HAVING THE GEAR STUCK IN A DOWN POS. WE DECIDED TO LAND ON THE TURF BTWN THE MAIN RWY AND THE TAXIWAY; AFTER THE GND CREW CHKED THE CONDITION OF THE 4000 FT STRETCH OF TURF.
