Narrative:

Starting approach to mcc airport, runway 34. We were arriving from the west and entering on a wide left base about three plus mi from the airport and at about 1800 ft MSL. I was concentrating on the runway and asked for 'flaps 15 degrees.' the captain lowered the flaps. At that time, we both looked up and saw a piper seneca from right to left fly across the nose at about 100-150 ft ahead and about 20 ft high. Evasive maneuver at that point would have been useless. We continued to a normal approach and landing. In the future, I will wait to cancel my IFR until closer to the airport or after landing.

Original NASA ASRS Text

Title: C560 ON L BASE VISUAL APCH TO RWY 34 MCC HAS AN NMAC WITH ANOTHER CLASS G PA34.

Narrative: STARTING APCH TO MCC ARPT, RWY 34. WE WERE ARRIVING FROM THE W AND ENTERING ON A WIDE L BASE ABOUT THREE PLUS MI FROM THE ARPT AND AT ABOUT 1800 FT MSL. I WAS CONCENTRATING ON THE RWY AND ASKED FOR 'FLAPS 15 DEGS.' THE CAPT LOWERED THE FLAPS. AT THAT TIME, WE BOTH LOOKED UP AND SAW A PIPER SENECA FROM R TO L FLY ACROSS THE NOSE AT ABOUT 100-150 FT AHEAD AND ABOUT 20 FT HIGH. EVASIVE MANEUVER AT THAT POINT WOULD HAVE BEEN USELESS. WE CONTINUED TO A NORMAL APCH AND LNDG. IN THE FUTURE, I WILL WAIT TO CANCEL MY IFR UNTIL CLOSER TO THE ARPT OR AFTER LNDG.
