Overview

• The Cessna Citation S550 flew more than a mile below its prescribed descent path, clipping power transmission lines approximately 90 to 95 feet above ground about 1.8 nautical miles from the Montgomery-Gibbs runway.
• Runway alignment indicator lights at Montgomery-Gibbs Executive Airport had been out of service since March 2022 due to environmental review delays, and the automated weather reporting system was also offline at the time.
• Audio recordings indicate the pilot, identified as Dave Shapiro, debated diverting to another airport and made seven key clicks in an attempt to activate pilot-controlled runway lights before impact.
• The crash on May 22 killed all six aboard, including Shapiro and drummer Daniel Williams, and left eight people on the ground with minor injuries as debris damaged a home and about 20 vehicles.
• Investigators have not yet assigned a probable cause and are analyzing cockpit voice and flight data recorders with a final report expected within two years of the accident.
