In a preliminary report on the July 10 crash of a Cessna 310R in Sanford, Fla., the NTSB said it could find “no obvious pre-impact mechanical malfunctions” in either of the airplane’s engines. As they reached 6,000 feet, one of the pilots told ATC, “Zero One November, declaring an emergency, we need, smoke in the cockpit, we need to land at Sanford.” A witness later reported seeing smoke coming from the left side of the airplane as the pilots maneuvered to land at Sanford, before it crashed into houses. The 1977 310R was flown by commercial pilot Bruce Kennedy and ATP Michael Klemm, senior captain for Nascar Aviation. Both pilots and three people on the ground were killed.
