The NTSB's narrative for the Cessna T210N final · quoted from the NTSB record
The pilot of the Cessna T210N said that he had landed on runway 25R and exited the runway on taxiway E. He said he contacted ground control and requested to taxi to the southeast T-hangars (requiring him to cross the active runway 25R). He said that ground control cleared him to taxi on taxiway A, to taxiway C, and hold short of runway 25R. The pilot said that upon reaching the intersection of taxiways A and C, he held on taxiway A (facing east) to permit any landing aircraft to exit the active runway at taxiway C. The pilot of a Sukhoi SU-29 (a tail wheel aircraft) said that he also landed on runway 25R and exited the runway on taxiway E. He changed his radio frequency to ground control and requested to taxi to the northeast T-hangars. Ground control cleared him to taxi on taxiway A to the T-hangars. The pilot said that he commenced to taxi. He said he saw the Cessna "at the last minute", and reduced his power and braked his aircraft. He said his propeller damaged the left elevator and left stabilizer of the Cessna.
