TUPELO, Miss. (WTVA) - An investigation reports a deadly plane crash in Tupelo appears to be connected to the exhaust system.
The National Transportation Safety Board says a piece of the exhaust fell off the engine on takeoff and landed on the runway just before the May 2016 crash.
Henry Jackson, 75, was pilotiing the aircraft and attempted to return to the airport after reporting smoke in the cockpit.
The plane crashed just north of the runway killing Jackson, his wife Gwynn Groggel, 70; Dr. Charles Torti, 69, and Carrie Torti, 59, all of Kerrville, Texas.
The NTSB report says a v-clamp and exhaust pipe were found on the runway and an inspection showed the parts were missing from the turbocharger on the plane's engine.
The report says similar issues have been responsible for fires on airplanes in other crashes.
