The pilot of a light single-engine airplane reported that while on a taxiway under air traffic control (ATC) instruction the airplane encountered jet blast, originating from a larger turbine-powered airplane being marshaled by ground personnel. Subsequently, the airplane's empennage lifted and the propeller and left wing struck the ground, which resulted in substantial damage to the firewall.
The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
The Federal Aviation Administration Aeronautical Information Manual in part states: "During ground operations and during takeoff, jet engine blast (thrust stream turbulence) can cause damage and upsets if encountered at close range. Exhaust velocity versus distance studies at various thrust levels have shown a need for light aircraft to maintain an adequate separation behind large turbojet aircraft. Pilots of larger aircraft should be particularly careful to consider the effects of their "jet blast" on other aircraft, vehicles, and maintenance equipment during ground operations."
Probable Cause: The pilot's failure to maintain a safe taxi distance from a large turbine-powered airplane, resulting in an encounter of the turbine-powered airplane's jet blast while taxiing.
