Narrative:

I announced turning base to final for runway 10 for touch-and-go, followed by a sbound departure. Hearing no traffic on or about to turn final, I continued my approach at the aircraft's recommended speed of 63 KIAS. With full flaps and almost idle power, I heard a loud 'bang, bang' and immediately began descending. I pushed the throttle to full and attempted to climb or at least hold altitude, with no success. To avoid a stall, I kept the throttle in full and nosed to a slightly nose-low attitude and headed for the airport (trying to avoid the trees before the boundary). Being pulled to the left, I knew I couldn't make the runway but there was grass to the left of it. Keeping the throttle in all the way to the ground (until flare), I landed on the grass safely. At that point, I shut down the engine, electrical system off, magnetos off/keys out, and I, knowing then that I had collided with another plane (and continued down, eventually landing on it) jumped out and checked for the cessna's passenger safety. No one was hurt and we were all amazed at the sight. I had not heard the cessna call final or the approach, nor did I hear the call anywhere else (like downwind, base, etc). When I announced final, there was no transmission of conflict by the other pilot(south). Next time I will definitely announce short final and rechk my approach corridor at that time.

Title: ACTUAL MIDAIR COLLISION BTWN A PIPER PA28-161 AND A C152 ON FINAL APCH TO AN UNCTLED ARPT. THE PIPER COLLIDED ON TOP OF THE CESSNA WITHOUT KNOWING WHAT HAPPENED, BUT HEARD A LOUD BANG. THE RPTR IN THE PIPER THEN ADDED FULL PWR IN AN ATTEMPT TO MAKE THE RWY. HE LANDED OFF TO THE SIDE OF THE RWY IN A GRASSY AREA. THERE WERE NO INJURIES AND BOTH ACFT SUSTAINED ONLY MINOR DAMAGE.

Narrative: I ANNOUNCED TURNING BASE TO FINAL FOR RWY 10 FOR TOUCH-AND-GO, FOLLOWED BY A SBOUND DEP. HEARING NO TFC ON OR ABOUT TO TURN FINAL, I CONTINUED MY APCH AT THE ACFT'S RECOMMENDED SPD OF 63 KIAS. WITH FULL FLAPS AND ALMOST IDLE PWR, I HEARD A LOUD 'BANG, BANG' AND IMMEDIATELY BEGAN DSNDING. I PUSHED THE THROTTLE TO FULL AND ATTEMPTED TO CLB OR AT LEAST HOLD ALT, WITH NO SUCCESS. TO AVOID A STALL, I KEPT THE THROTTLE IN FULL AND NOSED TO A SLIGHTLY NOSE-LOW ATTITUDE AND HEADED FOR THE ARPT (TRYING TO AVOID THE TREES BEFORE THE BOUNDARY). BEING PULLED TO THE L, I KNEW I COULDN'T MAKE THE RWY BUT THERE WAS GRASS TO THE L OF IT. KEEPING THE THROTTLE IN ALL THE WAY TO THE GND (UNTIL FLARE), I LANDED ON THE GRASS SAFELY. AT THAT POINT, I SHUT DOWN THE ENG, ELECTRICAL SYS OFF, MAGNETOS OFF/KEYS OUT, AND I, KNOWING THEN THAT I HAD COLLIDED WITH ANOTHER PLANE (AND CONTINUED DOWN, EVENTUALLY LNDG ON IT) JUMPED OUT AND CHKED FOR THE CESSNA'S PAX SAFETY. NO ONE WAS HURT AND WE WERE ALL AMAZED AT THE SIGHT. I HAD NOT HEARD THE CESSNA CALL FINAL OR THE APCH, NOR DID I HEAR THE CALL ANYWHERE ELSE (LIKE DOWNWIND, BASE, ETC). WHEN I ANNOUNCED FINAL, THERE WAS NO XMISSION OF CONFLICT BY THE OTHER PLT(S). NEXT TIME I WILL DEFINITELY ANNOUNCE SHORT FINAL AND RECHK MY APCH CORRIDOR AT THAT TIME.
