Oshkosh Whitman Regional Airport
Aircraft Accident/Incident Report

Oshkosh, Wisconsin 54901
Saturday, August 1, 1998 18:40 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was taxiing for departure on a north-south taxiway for a departure from runway 18R. He reported that the ATIS advised all traffic to watch the flagmen for ATC instructions. The pilot reported that he was watching the flagman as instructed. The pilot reported, 'The flagman gave me a signal to stop as I approached the intersection, and then changed to the right turn signal. I started my right turn. The flagman gave me no indication that there was an aircraft in my path, or that I should do anything other than complete the turn.' He reported that he was about halfway through the turn when his propeller struck the right wingtip of the RV-6. He reported, 'I was confident that this area was clear because the flagman, with a clear view, directed me to make the turn.'

NTSB Probable Cause Narrative

The pilot failed to maintain clearance from the other airplane while taxiing.
