Synopsis
CE550B flight crew reported the Captain's windshield fractured inflight and the flight crew requested priority handling and diverted.
Narrative
During the climb to cruise altitude FL410; between FL343 and 350 we heard a noise; like a cracking glass. Then; I saw the windshield on the Captain's side; cracking from the bottom to the top. Immediately; we stopped the climb and I asked the First Officer to request an emergency descent and to [request priority handling] due to the windshield damage; this in order to prevent a cabin decompression. At that time; we proceeded to wear our oxygen masks and monitor the cabin pressurization system; which was working fine at all times; we never lost cabin pressure. We requested vectors while both preparing the passengers and the aircraft for our diversion to the nearest and suitable airport; ZZZ1. Reaching a safe altitude; we told ATC and explained the situation with more details. Then; we proceeded to land.There were no injuries involved; the only aircraft damage was the windshield; which I think it could [have] happened due to temperature; pressure; or material fatigue. We had notified the company; in accordance with our flight operational procedures; complying with FAA regulations and operation specifications.
Second reporter narrative
Flight from ZZZ2 to ZZZ3. During climb to FL410; at FL343; crew heard glass cracking and immediately recognized a continuous cracking of the aircraft's windshield from bottom to top on the Captain's side. Proper action was taken; crew worked with ATC; initiated an emergency descent; diverted to nearest airport; [and] approached and landed safely into ZZZ1. Nobody was injured; all departments involved were notified; and all federal regulations were complied with.
