<< >> NASA ASRS Report 417885, October 1998

Near midair collision. Pilot of a mooney M20E (MO21) during cruise flight in class C airspace made a right turn to avoid unknown traffic 300 ft to his left. Departure controller made TA after its passing and informed the pilot that he should not deviate from assigned heading when operating in class C airspace.

Narrative:

We were flying VFR from ric, 1300 ft on heading 090 degrees, en route to W96. Ric did not notify us of approaching traffic. Traffic was spotted approximately 300 ft away on our left. Our course was deviated by approximately 10-15 degrees to the right for collision avoidance purposes. After the aircraft was no longer a factor, ric departure notified us of the other aircraft. Shortly thereafter, ric proceeded to rudely explain that when flying in class C airspace, no deviation from the heading is allowed. I acted under part 91.123.

Original NASA ASRS Text

Title: NMAC. PLT OF A MOONEY M20E (MO21) DURING CRUISE FLT IN CLASS C AIRSPACE MADE A R TURN TO AVOID UNKNOWN TFC 300 FT TO HIS L. DEP CTLR MADE TA AFTER ITS PASSING AND INFORMED THE PLT THAT HE SHOULD NOT DEVIATE FROM ASSIGNED HDG WHEN OPERATING IN CLASS C AIRSPACE.

Narrative: WE WERE FLYING VFR FROM RIC, 1300 FT ON HDG 090 DEGS, ENRTE TO W96. RIC DID NOT NOTIFY US OF APCHING TFC. TFC WAS SPOTTED APPROX 300 FT AWAY ON OUR L. OUR COURSE WAS DEVIATED BY APPROX 10-15 DEGS TO THE R FOR COLLISION AVOIDANCE PURPOSES. AFTER THE ACFT WAS NO LONGER A FACTOR, RIC DEP NOTIFIED US OF THE OTHER ACFT. SHORTLY THEREAFTER, RIC PROCEEDED TO RUDELY EXPLAIN THAT WHEN FLYING IN CLASS C AIRSPACE, NO DEV FROM THE HDG IS ALLOWED. I ACTED UNDER PART 91.123.
