Narrative:

At approximately ZB00 I was approaching hio for landing. I had been in radar contact with portland approach, on VFR flight following on a VFR flight from the dalles to hillsboro. Upon entering the hillsboro air traffic area, I had been visually idented and advised of a cessna on right downwind to runway 30. I was instructed to enter a right base leg for runway 30 and cleared to land, #3, behind the cessna on downwind. I reported visual contact with the cessna. When the cessna turned final for runway 30, I entered a right base leg for that runway and so reported to ATC. ATC thanked me for the report and noted that I was #2 to land, behind the cessna. When I was initiating my turn to final at about 800 ft AGL and 2 1/2 mi from the threshold of runway 30, a bonanza (apparently on the runway 30 centerline, in cruise confign) came within about 100 ft of me, right ahead of and slightly to my left. At that same time there was a transmission from the tower instructing the bonanza to do something. I do not recall what the instruction was, and an acknowledgement from the bonanza, as the bonanza was making a climbing left turn. Upon landing, I asked the local controller to speak to the watch supervisor concerning the near miss. The local controller directed me to the ground controller. She advised that the watch supervisor was not there. I asked for a phone number for the tower. I called the tower and spoke to controller X who said she was the ground controller. She advised that the watch supervisor had left for the day. She also advised that controller Y was the local controller at the time of the near miss. She proposed to take no action concerning the near miss, but that if I wished to report the matter, I should do so with the FSDO. I asked the controller to please make a note of the event and my contact in the tower log and bring the matter to the attention of the supervisor and chief. Controller X gave me the names of the supervisor and the tower chief and invited me to call them on monday.

Title: AN NMAC BTWN A TIGER AA5 AND A BONANZA ON A SHORT FINAL SE OF HIO, OR.

Narrative: AT APPROX ZB00 I WAS APCHING HIO FOR LNDG. I HAD BEEN IN RADAR CONTACT WITH PORTLAND APCH, ON VFR FLT FOLLOWING ON A VFR FLT FROM THE DALLES TO HILLSBORO. UPON ENTERING THE HILLSBORO ATA, I HAD BEEN VISUALLY IDENTED AND ADVISED OF A CESSNA ON R DOWNWIND TO RWY 30. I WAS INSTRUCTED TO ENTER A R BASE LEG FOR RWY 30 AND CLRED TO LAND, #3, BEHIND THE CESSNA ON DOWNWIND. I RPTED VISUAL CONTACT WITH THE CESSNA. WHEN THE CESSNA TURNED FINAL FOR RWY 30, I ENTERED A R BASE LEG FOR THAT RWY AND SO RPTED TO ATC. ATC THANKED ME FOR THE RPT AND NOTED THAT I WAS #2 TO LAND, BEHIND THE CESSNA. WHEN I WAS INITIATING MY TURN TO FINAL AT ABOUT 800 FT AGL AND 2 1/2 MI FROM THE THRESHOLD OF RWY 30, A BONANZA (APPARENTLY ON THE RWY 30 CTRLINE, IN CRUISE CONFIGN) CAME WITHIN ABOUT 100 FT OF ME, RIGHT AHEAD OF AND SLIGHTLY TO MY L. AT THAT SAME TIME THERE WAS A XMISSION FROM THE TWR INSTRUCTING THE BONANZA TO DO SOMETHING. I DO NOT RECALL WHAT THE INSTRUCTION WAS, AND AN ACKNOWLEDGEMENT FROM THE BONANZA, AS THE BONANZA WAS MAKING A CLBING L TURN. UPON LNDG, I ASKED THE LCL CTLR TO SPEAK TO THE WATCH SUPVR CONCERNING THE NEAR MISS. THE LCL CTLR DIRECTED ME TO THE GND CTLR. SHE ADVISED THAT THE WATCH SUPVR WAS NOT THERE. I ASKED FOR A PHONE NUMBER FOR THE TWR. I CALLED THE TWR AND SPOKE TO CTLR X WHO SAID SHE WAS THE GND CTLR. SHE ADVISED THAT THE WATCH SUPVR HAD LEFT FOR THE DAY. SHE ALSO ADVISED THAT CTLR Y WAS THE LCL CTLR AT THE TIME OF THE NEAR MISS. SHE PROPOSED TO TAKE NO ACTION CONCERNING THE NEAR MISS, BUT THAT IF I WISHED TO RPT THE MATTER, I SHOULD DO SO WITH THE FSDO. I ASKED THE CTLR TO PLEASE MAKE A NOTE OF THE EVENT AND MY CONTACT IN THE TWR LOG AND BRING THE MATTER TO THE ATTN OF THE SUPVR AND CHIEF. CTLR X GAVE ME THE NAMES OF THE SUPVR AND THE TWR CHIEF AND INVITED ME TO CALL THEM ON MONDAY.
