Narrative:

While in the landing pattern a light single aircraft ahead of me landed and apparently flipped to an inverted position. I could see an airplane in an unusual position from the air but at first did not realize that he had had an accident. I did a low approach/go around and saw that the airplane was upside down but saw no occupants emerging and no activity on the ground indicating a response from the airport. I advised unicom and considered that I might be the person soonest able to render aid, if needed. The aircraft showed no sign of being a hazard from my vantage point but was a few ft on the pavement, a few ft off, approximately 2000 ft from the threshold. I determined that I could land to a full stop well before reaching that point and did so. I taxied close enough to see that the occupants had alighted, saw fuel leaking, and taxied well clear. This action may violate the FARS regarding use of runways occupied, but I felt it to be a legitimate exercise of emergency authority granted to a PIC to deviate from the FARS to the extent required to meet an emergency.

Title: SMA LANDS ON FIRST HALF OF RWY WITH DISABLED ACFT ON RWY.

Narrative: WHILE IN THE LNDG PATTERN A LIGHT SINGLE ACFT AHEAD OF ME LANDED AND APPARENTLY FLIPPED TO AN INVERTED POS. I COULD SEE AN AIRPLANE IN AN UNUSUAL POS FROM THE AIR BUT AT FIRST DID NOT REALIZE THAT HE HAD HAD AN ACCIDENT. I DID A LOW APCH/GAR AND SAW THAT THE AIRPLANE WAS UPSIDE DOWN BUT SAW NO OCCUPANTS EMERGING AND NO ACTIVITY ON THE GND INDICATING A RESPONSE FROM THE ARPT. I ADVISED UNICOM AND CONSIDERED THAT I MIGHT BE THE PERSON SOONEST ABLE TO RENDER AID, IF NEEDED. THE ACFT SHOWED NO SIGN OF BEING A HAZARD FROM MY VANTAGE POINT BUT WAS A FEW FT ON THE PAVEMENT, A FEW FT OFF, APPROX 2000 FT FROM THE THRESHOLD. I DETERMINED THAT I COULD LAND TO A FULL STOP WELL BEFORE REACHING THAT POINT AND DID SO. I TAXIED CLOSE ENOUGH TO SEE THAT THE OCCUPANTS HAD ALIGHTED, SAW FUEL LEAKING, AND TAXIED WELL CLR. THIS ACTION MAY VIOLATE THE FARS REGARDING USE OF RWYS OCCUPIED, BUT I FELT IT TO BE A LEGITIMATE EXERCISE OF EMER AUTHORITY GRANTED TO A PIC TO DEVIATE FROM THE FARS TO THE EXTENT REQUIRED TO MEET AN EMER.
