Narrative:

The nose gear would not extend. The nose doors opened; but the wheel was still retracted. We followed all applicable emergency extension procedures to no avail. Crash equipment was requested and available. The aircraft slid on the nose gear doors to a stop on runway 22 with no further problems. We then lifted the nose and opened the hydraulic pressure dump valve and the nose gear came down and locked. The aircraft was then taxied to the hangar. Upon inspection it appeared the nose gear fork assembly had caught on the oil cooler as the clearance was not great enough. There was minor damage to the nose doors and fuselage near the door cutout. There were no injuries.
