Narrative:

While taxiing an aircraft around a right curving taxiway, I noticed that aircraft with full right steering was not negotiating the turn sharply enough. Right brake was applied to aid in turning action and felt a spongy response to it. At this time it was noticed that an idling aircraft was parked at the intersection of my taxiway and the one he was on. My next action to prevent colliding with him was to apply full brakes in an effort to stop. In response the left brake grabbed harder and tended to point the aircraft on a collision course toward the other. At the time, only full right steering and brake was applied in an effort to miss the other aircraft as much as possible. My left wing tip struck the idling aircraft's propeller spinner shortly thereafter. Next I prevented my plane from departing the taxiway surface and gingerly taxied the plane to a stop off the taxiway by making 2 left turns using the left brake to stop in the airport ramp area. No personal injuries were sustained in either aircraft.

Title: TAXIING SMA COLLIDES WITH ANOTHER SMA. REPORTER BLAMES BRAKE PROBLEMS.

Narrative: WHILE TAXIING AN ACFT AROUND A RIGHT CURVING TXWY, I NOTICED THAT ACFT WITH FULL RIGHT STEERING WAS NOT NEGOTIATING THE TURN SHARPLY ENOUGH. RIGHT BRAKE WAS APPLIED TO AID IN TURNING ACTION AND FELT A SPONGY RESPONSE TO IT. AT THIS TIME IT WAS NOTICED THAT AN IDLING ACFT WAS PARKED AT THE INTXN OF MY TXWY AND THE ONE HE WAS ON. MY NEXT ACTION TO PREVENT COLLIDING WITH HIM WAS TO APPLY FULL BRAKES IN AN EFFORT TO STOP. IN RESPONSE THE LEFT BRAKE GRABBED HARDER AND TENDED TO POINT THE ACFT ON A COLLISION COURSE TOWARD THE OTHER. AT THE TIME, ONLY FULL RIGHT STEERING AND BRAKE WAS APPLIED IN AN EFFORT TO MISS THE OTHER ACFT AS MUCH AS POSSIBLE. MY LEFT WING TIP STRUCK THE IDLING ACFT'S PROP SPINNER SHORTLY THEREAFTER. NEXT I PREVENTED MY PLANE FROM DEPARTING THE TXWY SURFACE AND GINGERLY TAXIED THE PLANE TO A STOP OFF THE TXWY BY MAKING 2 LEFT TURNS USING THE LEFT BRAKE TO STOP IN THE ARPT RAMP AREA. NO PERSONAL INJURIES WERE SUSTAINED IN EITHER ACFT.
