Nobody was injured.

The pilot’s improper decision to land the airplane on a wet runway, in heavy rain, with tires worn beyond safe limits, which resulted in a hydroplaning condition and subsequent loss of directional control.

Read the full NTSB narrative

The airline transport pilot reported that rain was intensifying as the airplane approached the runway and that the runway appeared to be wet. After landing smoothly and while decelerating through 80-90 knots, the airplane hydroplaned and departed the left side of the runway. An 8-knot crosswind from the left prevailed. The left main landing gear collapsed, and the airplane came to rest in the grass about 180° from the runway heading, which resulted in structural damage to the left main gear well. Postaccident examination of the main landing gear tires revealed that three tires had no measurable tread, and the fourth tire had only 1.17 mm of tread. The tire manufacturer stated that tires should be removed if tread wear reached the base of any groove. White skid marks were found on the runway, indicative of a hydroplaning condition. Witnesses reported heavy rain and standing water on the runway at the time of the accident.
