NTSB Factual Report

On July 13, 2017, about 1245 Pacific daylight time, a Cirrus Design Corp SR22T, N821SG, sustained substantial damage when it impacted terrain about 1/2 mile west of the Sonoma Skypark Airport (0Q9) Sonoma, California. The private pilot was fatally injured, two passengers were seriously injured, and one passenger sustained minor injuries. The airplane was registered to DDLV LLC, and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan had been filed. The personal flight departed from Sonoma Skypark about 1244 with a planned destination of Reid-Hillview Airport of Santa Clara County, San Jose, California.

Several witnesses located near 0Q9 reported that they heard the engine "sputter" a few times as it passed their position. Subsequently, they heard a louder sound and shortly afterwards observed the airplane's parachute system deploying at a low altitude. Most of the witnesses saw the airplane descend just prior to losing sight of it at the tree tops, and shortly before it impacted the ground.

Examination of the accident site by the National Transportation Safety Board (NTSB), investigator-in-charge (IIC), revealed that all major structural components and primary flight controls of the airplane, were located at the accident site.

The airplane was recovered to a secure facility for further examination.
