NTSB summary

HISTORY OF FLIGHT On March 11, 2004, at 2035 Pacific standard time, a Mitsubishi MU-2B-40, N966MA, crashed into the Napa River under unknown circumstances, while on approach to the Napa County Airport (APC), Napa, California. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The airplane was destroyed. The private pilot and one passenger were fatally injured. Visual meteorological conditions prevailed for the cross-country flight that departed the Imperial County Airport (IPL), Imperial, California, at an undetermined time.

Local officials and the Civil Air Patrol initiated a search on March 16, 2004, in the Napa River area. They located the airplane on March 18, 2004, in the Napa River, 3 miles south of APC.

At 2030, he reported leaving 6,000 feet; he also stated that he had the information for Napa Airport, and had it in sight. The controller cleared him for the approach.

A Safety Board specialist plotted recorded radar d

Probable cause
