Incident Overview
A pilot of a single-engine airplane reported that after landing, while taxiing to his hangar, a regional jet was stopped on the active taxiway, blocking his intended path. The pilot of the airplane radioed over the common traffic advisory frequency and asked the regional jet to "move up so he could taxi behind" in order to proceed to his hangar. The jet captain responded with "Standby" and then rolled forward and stopped. The pilot of the airplane continued his taxi, but as the airplane approached the rear of the jet, the jet blast blew the airplane off the taxiway and flipped the airplane upside down.
Damage and Mechanical Status
The airplane sustained substantial damage to both wings and the firewall. The pilot reported that there were no mechanical malfunctions or failures with the airplane prior to or during flight that would have precluded normal operation.
FAA Guidance on Jet Blast
According to the Federal Aviation Administration Aeronautical Information Manual, section 7-3-1(b) 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."
