NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.
Following an uneventful landing, the student pilot and flight instructor were cleared to taxi the Cessna 172H to the ramp. While taxiing on a taxiway, parallel to an active runway, the flight instructor and student pilot observed a McDonnell Douglas MD-80 transport category airplane holding short of the runway. As the Cessna 172H neared the MD-80's position, the student pilot applied aileron control inputs for possible jet blast and deviated away from the MD-80, towards the inner ramp area. The flight instructor advised the student pilot to stop the airplane due to the MD-80 being positioned "farther back from the hold short line of 11L than initially thought and the presence of a Boeing 757 parked in the inner ramp area." As the Cessna 172H slowed to a stop, the MD-80 "increased engine thrust" to taxi onto the runway. Subsequently, the MD-80’s jet blast tipped the Cessna 172H over onto its right wing, which resulted in minor damage to the outboard wingtip. The tower controller reported that he began to clear the MD-80 for takeoff as he scanned the active runway to ensure all crossing aircraft were clear. The controller then "looked back” and saw the Cessna 172H taxiing behind the MD-80. The controller stated that he stopped issuing the takeoff clearance, however the MD-80 had already powered up.
The National Transportation Safety Board determines the probable cause(s) of this incident to be: The flight instructor’s inadequate situational awareness while taxiing that led to an encounter with jet blast. Full narrative available
