While taxiing for takeoff, a Boeing 727's jet exhaust lifted the wing of a following Cessna 206, causing the Cessna's right wing to strike the ground and sustain minor damage.

Incident Overview

A pilot of a Boeing 727 reported that after engine start, air traffic control directed the aircraft to taxi for takeoff. The marshaller signaled the pilot to move forward. The pilot advanced the throttle to 65% power to break away from the parking position, then reduced it to idle. At no time was the pilot advised that another aircraft was behind the Boeing 727.

Damage to the Cessna 206

The exhaust from the jet engine of the Boeing 727 lifted the wing of a Cessna 206 that was taxiing behind the larger aircraft. The right wing of the Cessna struck the ground, sustaining minor damage. The crew of the Boeing 727 was unaware of the event.

Contributing Factors

The source does not provide analysis or causal factors beyond the sequence of events. The pilot of the Boeing 727 was not informed of the trailing Cessna 206, and the exhaust from the jet engine caused the wing of the smaller aircraft to lift.
