Narrative:

At departure, I requested a high speed low pass as I have done many times in the past. On downwind, tower cleared me for a low approach behind a twin that was landing. Controller specifically requested I do the low approach over the runway. As I was on the low approach, at about 160 mph and about 100 ft AGL, I saw I was coming closer than I had expected to the twin that was still on the runway starting to turn off. Controller said 'turn right.' I turned right immediately, 45 degrees, and started to climb and departed the pattern as previously cleared. I have contingencies in my mind when I do low approachs: I have the momentum to pull up and depart or even land on the remaining runway, also I can turn to one side or another and also throttle back. Later I realized that, although I felt safe in this low approach and had thought through my contingencies, I perhaps came closer to the aircraft on the runway than was prudent. I had gained too rapidly on the landing twin. I'm not sure of my altitude, as I was looking outside. I was on the right side of the runway and the twin on the left side (runway is 150 ft wide). In the future, when I'm cleared for a low approach, I will plan my pattern better, especially if I'm following another aircraft, I will hold my altitude higher, if someone is still on the runway I will pull up sooner and keep a wide clearance.

Title: AN SMA HAD TO ABORT ITS 'LOW PASS' DUE TO AN ACFT ON THE RWY.

Narrative: AT DEP, I REQUESTED A HIGH SPD LOW PASS AS I HAVE DONE MANY TIMES IN THE PAST. ON DOWNWIND, TWR CLRED ME FOR A LOW APCH BEHIND A TWIN THAT WAS LNDG. CTLR SPECIFICALLY REQUESTED I DO THE LOW APCH OVER THE RWY. AS I WAS ON THE LOW APCH, AT ABOUT 160 MPH AND ABOUT 100 FT AGL, I SAW I WAS COMING CLOSER THAN I HAD EXPECTED TO THE TWIN THAT WAS STILL ON THE RWY STARTING TO TURN OFF. CTLR SAID 'TURN R.' I TURNED R IMMEDIATELY, 45 DEGS, AND STARTED TO CLB AND DEPARTED THE PATTERN AS PREVIOUSLY CLRED. I HAVE CONTINGENCIES IN MY MIND WHEN I DO LOW APCHS: I HAVE THE MOMENTUM TO PULL UP AND DEPART OR EVEN LAND ON THE REMAINING RWY, ALSO I CAN TURN TO ONE SIDE OR ANOTHER AND ALSO THROTTLE BACK. LATER I REALIZED THAT, ALTHOUGH I FELT SAFE IN THIS LOW APCH AND HAD THOUGHT THROUGH MY CONTINGENCIES, I PERHAPS CAME CLOSER TO THE ACFT ON THE RWY THAN WAS PRUDENT. I HAD GAINED TOO RAPIDLY ON THE LNDG TWIN. I'M NOT SURE OF MY ALT, AS I WAS LOOKING OUTSIDE. I WAS ON THE R SIDE OF THE RWY AND THE TWIN ON THE L SIDE (RWY IS 150 FT WIDE). IN THE FUTURE, WHEN I'M CLRED FOR A LOW APCH, I WILL PLAN MY PATTERN BETTER, ESPECIALLY IF I'M FOLLOWING ANOTHER ACFT, I WILL HOLD MY ALT HIGHER, IF SOMEONE IS STILL ON THE RWY I WILL PULL UP SOONER AND KEEP A WIDE CLRNC.
