Narrative:

Upon terminating radar advisories with otis AFB on 118.2, I called hyannis tower notifying them I was 5 mi northwest with current information and intent to land. I was then given the choice of entering left or right downwind for runway 33. I responded by notifying the tower I was entering left downwind for runway 33. While on the downwind leg prior to turning base, another aircraft called the tower requesting a touch and go on runway 33. The tower informed the other pilot they were #2 after the small aircraft now on downwind and this transmission was acknowledged as being understood. After turning base for runway 33 the tower again told me cleared to land and again advised the other pilot he was #2 to land. At this time the other pilot responded by acknowledging visual contact with my aircraft and he was clear to perform a touch and go on runway 33. While on final approach the second aircraft lost visual contact with my aircraft and assumed I had landed and was clear of the runway. Without the tower or the other pilot realizing aircraft was directly under my wing. Due to my low wing and the other craft being a high wing confign, neither pilot was able to observe the other. On short final (1/8-1/4 mi) the second pilot called the tower asking if I was clear the runway. At this time the tower responded 'my god, he's right above you, turn left and climb now. I was also preparing to execute a go around, but was told clear to land. My altitude at this time was about 300' MSL, when I observed the other craft turn, I would estimate his altitude to be less than 100' below me. After taxiing to the parking area I noticed the other aircraft again execute a touch and go on runway 33M, then leave pattern. I feel that had the other pilot not called the tower, we would have collided on the runway in approximately 20-30 seconds.

Title: ACFT #1 CLEARED TO LAND, ACFT #2 TOLD HE WAS #2 FOR LNDG. HAD #1 IN SIGHT. ACFT 2 LOST SIGHT OF 1 ON FINAL, THOUGHT HE HAD LANDED. ASKED TWR IF CLEAR OF RWY. TWR REALIZED ACFT WERE BOTH ON FINAL, ONE ABOVE THE OTHER. TOLD 2 TO TURN.

Narrative: UPON TERMINATING RADAR ADVISORIES WITH OTIS AFB ON 118.2, I CALLED HYANNIS TWR NOTIFYING THEM I WAS 5 MI NW WITH CURRENT INFO AND INTENT TO LAND. I WAS THEN GIVEN THE CHOICE OF ENTERING LEFT OR RIGHT DOWNWIND FOR RWY 33. I RESPONDED BY NOTIFYING THE TWR I WAS ENTERING LEFT DOWNWIND FOR RWY 33. WHILE ON THE DOWNWIND LEG PRIOR TO TURNING BASE, ANOTHER ACFT CALLED THE TWR REQUESTING A TOUCH AND GO ON RWY 33. THE TWR INFORMED THE OTHER PLT THEY WERE #2 AFTER THE SMA NOW ON DOWNWIND AND THIS XMISSION WAS ACKNOWLEDGED AS BEING UNDERSTOOD. AFTER TURNING BASE FOR RWY 33 THE TWR AGAIN TOLD ME CLRED TO LAND AND AGAIN ADVISED THE OTHER PLT HE WAS #2 TO LAND. AT THIS TIME THE OTHER PLT RESPONDED BY ACKNOWLEDGING VISUAL CONTACT WITH MY ACFT AND HE WAS CLEAR TO PERFORM A TOUCH AND GO ON RWY 33. WHILE ON FINAL APCH THE SECOND ACFT LOST VISUAL CONTACT WITH MY ACFT AND ASSUMED I HAD LANDED AND WAS CLEAR OF THE RWY. WITHOUT THE TWR OR THE OTHER PLT REALIZING ACFT WAS DIRECTLY UNDER MY WING. DUE TO MY LOW WING AND THE OTHER CRAFT BEING A HIGH WING CONFIGN, NEITHER PLT WAS ABLE TO OBSERVE THE OTHER. ON SHORT FINAL (1/8-1/4 MI) THE SECOND PLT CALLED THE TWR ASKING IF I WAS CLEAR THE RWY.

AFTER TAXIING TO THE PARKING AREA I NOTICED THE OTHER ACFT AGAIN EXECUTE A TOUCH AND GO ON RWY 33M, THEN LEAVE PATTERN. I FEEL THAT HAD THE OTHER PLT NOT CALLED THE TWR, WE WOULD HAVE COLLIDED ON THE RWY IN APPROX 20-30 SECONDS.
