Narrative:
Aircraft nosed over on landing; causing propeller; nose cone; and lower cowling to come in contact with the runway. WX VMC; wind calm. Parking brake appeared to be engaged on landing; causing the event. Aircraft has; in previous events that caused no damage; appeared to have 1 brake set during flight; causing a turn toward the side of the runway upon landing. I have always been able to disengage the brake prior to departing the runway. I have incorporated into my pre-landing checks to pump the brakes (to disengage the parking brake; if it has been engaged in flight). Callback conversation with reporter revealed the following information: reporter owns the aircraft and stated that it had exhibited uneven braking in the past. Brakes would both react equally after moderate brake application; so the problem was ignored. In this instance; however; the aircraft immediately veered off the runway. Reporter believes that a tab; which locks rod into position to set parking brake; may have been dragging. This could cause the brake to be partially set. Reporter has since deactivated parking brake.
Original NASA ASRS Text
Title: M-7 LANDED WITH PARKING BRAKE SET; AND ACFT NOSED OVER AFTER TOUCHDOWN. PROP MADE CONTACT WITH RUNWAY.
Narrative: ACFT NOSED OVER ON LNDG; CAUSING PROP; NOSE CONE; AND LOWER COWLING TO COME IN CONTACT WITH THE RWY. WX VMC; WIND CALM. PARKING BRAKE APPEARED TO BE ENGAGED ON LNDG; CAUSING THE EVENT. ACFT HAS; IN PREVIOUS EVENTS THAT CAUSED NO DAMAGE; APPEARED TO HAVE 1 BRAKE SET DURING FLT; CAUSING A TURN TOWARD THE SIDE OF THE RWY UPON LNDG. I HAVE ALWAYS BEEN ABLE TO DISENGAGE THE BRAKE PRIOR TO DEPARTING THE RWY. I HAVE INCORPORATED INTO MY PRE-LNDG CHKS TO PUMP THE BRAKES (TO DISENGAGE THE PARKING BRAKE; IF IT HAS BEEN ENGAGED IN FLT). CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: REPORTER OWNS THE ACFT AND STATED THAT IT HAD EXHIBITED UNEVEN BRAKING IN THE PAST. BRAKES WOULD BOTH REACT EQUALLY AFTER MODERATE BRAKE APPLICATION; SO THE PROBLEM WAS IGNORED. IN THIS INSTANCE; HOWEVER; THE ACFT IMMEDIATELY VEERED OFF THE RWY. REPORTER BELIEVES THAT A TAB; WHICH LOCKS ROD INTO POSITION TO SET PARKING BRAKE; MAY HAVE BEEN DRAGGING. THIS COULD CAUSE THE BRAKE TO BE PARTIALLY SET. REPORTER HAS SINCE DEACTIVATED PARKING BRAKE.
