Narrative:
En route from bed to bdl, we picked up a vibration at higher speeds, which we did not think was a part of the normal vibration of the aircraft. Slowed from 290 KTS to 250 KTS and vibration disappeared. Since this was a repos flight without passenger and we had lots of time, we decided to land and look the aircraft over, thinking that we may have a dropping landing light or gear door not fully flush with the fuselage. Landed uneventfully and walked around aircraft. Could find nothing out of order. Called maintenance and decided to repos from bdl to swf where there was a citation service center just 60 mi west. Picked up no vibration from bdl to swf and left aircraft at the service center where they found a loose gear door fitting.
