On February 4, 2009, about 0852 Pacific standard time, a Douglas DC-3/65AR, N834TP, collided with terrain during takeoff at Mojave, California. The National Test Pilot School was operating the airplane under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The certified flight instructor (CFI) and the student pilot were not injured; the airplane sustained substantial damage to the fuselage and wings from impact forces. The local instructional flight was departing. Visual meteorological conditions prevailed, and no flight plan had been filed.
The YC-14 was Boeing's entrant into the USAF's Advanced Medium STOL Transport (AMST) competition, which aimed to replace the C-130 Hercules as the USAF's standard STOL tactical transport. Although both the YC-14 and the competing McDonnell Douglas YC-15 were successful, neither aircraft entered production, and the AMST project was eventually shut down in 1979.
