Narrative:

A go around was conducted due to nose landing gear disagreement warning. I then called flaps 8 degrees; gear up; without thinking about looking at the QRH first. The message went away quickly and we got vectored around for another approach really quick. The WX was scattered to broken just above and it was very rough; perhaps light turbulence. Since the message went away; I was more concerned with getting set up for another approach and landing. Next time I will ask for delay vectors to slow things down. Callback conversation with reporter revealed the following information: reporter stated that the airport is located in a valley and on the approach it was bumpy with light turbulence and believed the shaking around caused the nose gear warning. After they climbed out; the light and message extinguished and all indications were normal. In talking with maintenance; this type of incident is not at all uncommon in bumpy and turbulent WX.

Title: A CRJ200 ON APCH AT 3000 FT MADE A GAR DUE TO NOSE GEAR UNSAFE WARNING. DURING CLBOUT; WARNING WENT AWAY.

Narrative: A GAR WAS CONDUCTED DUE TO NOSE LNDG GEAR DISAGREEMENT WARNING. I THEN CALLED FLAPS 8 DEGS; GEAR UP; WITHOUT THINKING ABOUT LOOKING AT THE QRH FIRST. THE MESSAGE WENT AWAY QUICKLY AND WE GOT VECTORED AROUND FOR ANOTHER APCH REALLY QUICK. THE WX WAS SCATTERED TO BROKEN JUST ABOVE AND IT WAS VERY ROUGH; PERHAPS LIGHT TURB. SINCE THE MESSAGE WENT AWAY; I WAS MORE CONCERNED WITH GETTING SET UP FOR ANOTHER APCH AND LNDG. NEXT TIME I WILL ASK FOR DELAY VECTORS TO SLOW THINGS DOWN. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE ARPT IS LOCATED IN A VALLEY AND ON THE APCH IT WAS BUMPY WITH LIGHT TURB AND BELIEVED THE SHAKING AROUND CAUSED THE NOSE GEAR WARNING. AFTER THEY CLBED OUT; THE LIGHT AND MESSAGE EXTINGUISHED AND ALL INDICATIONS WERE NORMAL. IN TALKING WITH MAINT; THIS TYPE OF INCIDENT IS NOT AT ALL UNCOMMON IN BUMPY AND TURBULENT WX.
