Investigators are trying to determine how two small airplanes were damaged at McClellan-Palomar Airport in Carlsbad on Monday afternoon when a larger business jet began taxiing for takeoff, according to the Federal Aviation Administration.
The twin-engine Gulfstream 550 business jet blew over the two single-engine Cessna 152s as it began its departure about 2:45 p.m., said Ian Gregor, a spokesman for the FAA.
"At this point, we're only investigating to see how this incident occurred and why the exhaust from a large business jet blew over the two smaller planes," Gregor said.
The Cessnas were parked and unoccupied on the western flight ramp area northeast of the air traffic control tower when the incident occurred, according to the FAA. Both Cessnas were significantly damaged, Gregor said.
The Gulfstream is registered to APC Aviation out of Houston, Texas. The two Cessnas are registered to Pinnacle Aviation Services, a flight school that operates out of the airport.
The FAA and the National Transportation Safety Board are investigating the incident.
