Narrative:

Flying bi-plane in shallow left turn and had just crossed interstate highway at almost 90 degree. Other aircraft, blue/white cessna - (probably 172), which was most likely a traffic spotting flight, made a left descending turn to avoid our aircraft. This occurred just outside (1.5 mn) class 'D' airspace. Was not able to see other aircraft because engine cowl on bi- plane makes it difficult to see straight ahead at the same altitude or lower.

Original NASA ASRS Text

Title: NMAC BTWN A BI-PLANE AND A SMA SEL JUST OUTSIDE OF CLASS D AIRSPACE.

Narrative: FLYING BI-PLANE IN SHALLOW L TURN AND HAD JUST CROSSED INTERSTATE HWY AT ALMOST 90 DEG. OTHER ACFT, BLUE/WHITE CESSNA - (PROBABLY 172), WHICH WAS MOST LIKELY A TFC SPOTTING FLT, MADE A L DSNDING TURN TO AVOID OUR ACFT. THIS OCCURRED JUST OUTSIDE (1.5 MN) CLASS 'D' AIRSPACE. WAS NOT ABLE TO SEE OTHER ACFT BECAUSE ENG COWL ON BI- PLANE MAKES IT DIFFICULT TO SEE STRAIGHT AHEAD AT THE SAME ALT OR LOWER.
