This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

On October 13, 2016, about 1645 Mountain daylight time, a Short Bros SD3-60 Sherpa, N148Z, sustained minor damage following a nose gear collapse during landing, at the Missoula International Airport (MSO) Missoula, Montana. Two Airline Transport Pilots, the only occupants of the airplane, were not injured. The airplane was registered to and operated by United States Department of Agriculture (USDA), as a public use aircraft in support of the Forest Service. Visual meteorological conditions prevailed and a visual flight rules (VFR) flight plan was filed for the ferry flight which originated from Kingman Airport, Kingman, Arizona, about 1253 Mountain standard time.

The pilots reported that prior to landing, they had an unsafe nose gear indication. After multiple unsuccessful attempts to get the nose gear to extend and indicate that it was down and locked, they came in for a landing. During the landing roll, as the airplane's nose was lowered, the nose gear collapsed, and the forward section of the bottom of the fuselage, made contact with the runway surface. Once the airplane came to a stop, the flight crew egressed.

Examination of the airplane by the operator revealed that the underside of the fuselage, near the nose wheel, sustained minor damage.
