Narrative

I WAS FLYING MY PITTS FROM BJC; JEFFCO ARPT; TO GXY; WELD COUNTY ARPT AT 7500 FT; HDG NE. THERE ARE BLIND SPOTS IN THE PITTS AT THE 10 AND 2 O'CLOCK POS WHERE THE INTERPLANE STRUTS ATTACH TO THE TOP WING. BECAUSE OF THIS LIMITATION I NORMALLY ROCK THE WINGS TO VISUALLY CLR THE AREA. I RAISED THE L WING AND SAW A COMMERCIAL BEECH 1900 800 FT AWAY; LEVEL; AT MY ALT; ON A DEAD COLLISION COURSE HDG SE. I IMMEDIATELY PUSHED DOWN (ABOUT MINUS 2 G'S) LOOKED UP AND SAW THE BEECH PASS OVER ME AT ABOUT 150 FT. THERE WAS NO INDICATION THAT ANYONE ON THE BEECH SAW ME SINCE THE AIRPLANE KEPT RIGHT ON FLYING LEVEL. THERE IS NO DOUBT IN MY MIND THAT IF I HAD NOT TAKEN EVASIVE ACTION THAT WE WOULD HAVE HIT. FROM THE TIME I SAW THE BEECH AND STARTED TO PUSH OVER WAS NO MORE THAN 2.5 SECONDS. I PUSHED DOWN BECAUSE I WANTED TO BE ABLE TO SEE THE OTHER ACFT AS LONG AS I COULD. I AM A FIRM BELIEVER IN THE SEE AND BE SEEN CONCEPT AND IT WORKS AS LONG AS ONE LOOKS. I ALSO BELIEVE THAT PLT REACTION TIMES ARE FASTER THAN WE ARE GENERALLY GIVEN CREDIT FOR. GRANTED THE PITTS IS A VERY RESPONSIVE AIRPLANE; MY REACTION TIME WOULD BE THE SAME NO MATTER WHAT ACFT I WAS FLYING. I BELIEVE THAT THE BEECH WAS FLYING FROM FNL; FORT COLLINS/LOVELAND TO DEN. I AM SUBMITTING THIS RPT AT THIS TIME BECAUSE YESTERDAY I READ ANOTHER ARTICLE ON THE LIMITATIONS OF THE SEE AND BE SEEN CONCEPT AND PLT REACTION TIMES IN NEAR MISS/MIDAIR EVENTS. I WOULD HOPE THIS INCIDENT GETS INTO YOUR DATA BANK AS A POSITIVE FOR SEE AND BE SEEN.
