On February 28, 1984, a Cessna 172A (registration N7168T) was involved in an aviation accident near San Jose, CA. Investigators recorded the probable cause as: The pilot's failure to maintain adequate separation from the DC-9 during taxi operations, which resulted in the Cessna encountering jet blast and nosing over. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A Cessna 172 pilot was cautioned about turbulence behind a departing DC-9 but proceeded to taxi across the runway, resulting in the aircraft nosing over due to jet blast.
What happened
The pilot of a Cessna 172 requested clearance to taxi to Runway 30R and received approval for that route. While moving along the taxiway, he was advised by air traffic control regarding turbulence generated behind a DC-9 aircraft. That DC-9 was positioned on the adjacent Runway 30L, waiting for its own takeoff clearance.
The Cessna pilot attempted to pass the DC-9 just as the larger jet received clearance to enter Runway 30L and hold short of the active runway environment. As the two aircraft were in close proximity, the Cessna encountered significant jet blast from the DC-9's engines. The force of the airflow caused the light aircraft to lose directional control and nose over.
The investigation
Examination of the Cessna 172 confirmed substantial damage to the forward fuselage and landing gear assembly consistent with a nose-over impact. No mechanical failures were identified that would have contributed to the loss of control prior to the encounter with the jet blast.
Probable cause
The pilot's failure to maintain adequate separation from the DC-9 during taxi operations, which resulted in the Cessna encountering jet blast and nosing over.
