On January 7, 2017, at 1506 eastern standard time, a Mitsubishi MU-2 airplane, N48NP, departed the left side of the snow covered runway after landing at Jerry Tyler Memorial Airport (3TR), Niles, Michigan. The private rated pilot was not injured and the airplane sustained substantial damage. The airplane was registered to and operated by a private individual under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed at the time of the accident and the flight was operated on an instrument flight rules (IFR) flight plan. The flight departed Smyrna Airport (MQY), Smyrna, Tennessee, and 3TR was the intended destination.
The pilot stated that he did not find any Notice to Airmen (NOTAMs) concerning the runway not being plowed. The pilot was cleared for the RNAV 33 approach to 3TR. When the airport was in sight, the pilot circled over the runway and activated airport lights in order to clearly identify the runway. The landing was uneventful until the pilot retarded the power levers into beta range and the airplane made an unexpected left turn then exited the runway. The airplane spun and came to rest in the snow covered field on the left side of the runway.
The airport snow plow operator stated that he checked the runway conditions on the morning of the accident and noted a light dusting to ½ inch of snow in some areas, but the pavement was still visible. He left town and returned about 1530 at which time he heard about the accident and observed two or more inches of snow on the runway.
At 1454, the automated weather observation station at South Bend International Airport (SBN), South Bend, Indiana, located about 9 miles south of the accident site, recorded: wind from 250 degrees at 14 knots, 6 statute miles visibility, haze, clouds overcast at 3,700 ft, temperature 12°F, dew point 5°F, and a barometric pressure of 30.47 inches of mercury. Remarks: unknown precipitation began at 1428 and ended at 1438; snow ended at 1428.
The airplane was retained for further examination.
