Narrative:

After pleasure flight, refueled at self service fuel pump. The 2 other pilots walked to the office. I got in, started engine, released hand brake and began taxiing to the tie-downs. When I started a left turn onto our ramp lane, I found that my foot pressure on the left toe brake pedal was not having the desired or expected effect and the aircraft proceeded to turn on a wider radius and the right wingtip struck the propeller of a piper PA28-160 which was parked there. I was unable to stop in time to avoid the collision. In later reconstructing of the event, I found that if my feet were placed high enough on the rudder pedals, my toes would press against a horizontal structural bar above and behind the toe brake pedals and would not actuate the brakes when pressure was applied.

Narrative: AFTER PLEASURE FLT, REFUELED AT SELF SVC FUEL PUMP. THE 2 OTHER PLTS WALKED TO THE OFFICE. I GOT IN, STARTED ENG, RELEASED HAND BRAKE AND BEGAN TAXIING TO THE TIE-DOWNS. WHEN I STARTED A L TURN ONTO OUR RAMP LANE, I FOUND THAT MY FOOT PRESSURE ON THE L TOE BRAKE PEDAL WAS NOT HAVING THE DESIRED OR EXPECTED EFFECT AND THE ACFT PROCEEDED TO TURN ON A WIDER RADIUS AND THE R WINGTIP STRUCK THE PROP OF A PIPER PA28-160 WHICH WAS PARKED THERE. I WAS UNABLE TO STOP IN TIME TO AVOID THE COLLISION. IN LATER RECONSTRUCTING OF THE EVENT, I FOUND THAT IF MY FEET WERE PLACED HIGH ENOUGH ON THE RUDDER PEDALS, MY TOES WOULD PRESS AGAINST A HORIZ STRUCTURAL BAR ABOVE AND BEHIND THE TOE BRAKE PEDALS AND WOULD NOT ACTUATE THE BRAKES WHEN PRESSURE WAS APPLIED.
