N332BA

Circumstances
		On a cargo flight from Rifle to Grand Junction, Colorado, the pilot completed the approach checklis. After deploying undercarriage, three green lights appeared on the panel and the pilot completed his landing. The aircraft landed on its main landing gear and the nose drop past level and struck the runway surface. The aircraft skidded for approximately 3,000 feet before stopping on the main runway. The investigations will try to understand why the nose gear did not extend despite the fact that three green lights were on.
