What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: N321GL executed an instrument approach to rw 19 at Portland, TN, (1M5) and completed a low approach to evaluate the runway conditions prior to landing. There was no one at the airport to issue a field conditions report on UNICOM. The visual evaluation indicated that the approach end of the runway was clear, as was a patch 1/2 down the 5000 foot runway on the west side. When N321GL landed, what appeared to be a light dusting of snow was discovered to be 3 inches to 4 inches of slushy snow. As speed decreased the aircraft hydroplaned and weatherveined leaving the right side of RW19 at the 3000 foot point, and came to rest 90 degrees to the right of the runway heading, 50 feet to the right of the runway surface, and straddling a snow filled ditch. The nose gear collapsed, and the left main gear fairing was damaged. Mud was splattered over the left wing and on the left engine cowl and intake area. There did not appear to be any other significant damage to structures or skin.
