Narrative:

While holding in position for takeoff on runway 5R at willow run, the tower was working a cessna 152 or 172 in closed pattern on runway 27R. As the cessna turned downwind, tower made repeated attempts to call. Other aircraft answered and there was confusion. The cessna finally responded after he passed beyond runway 5R. He was instructed to fly eastbound and we were cleared for takeoff. I instructed the crew and 1 jumpseat rider to pay close attention as there was a lot of traffic. After takeoff, the copilot and jumpseat rider alerted me to traffic 12 O'clock, 1/4 mi, 300 ft above us. I pushed over at approximately 500 ft AGL and started a left turn to avoid traffic, the cessna that was on downwind was in a right turn on an approximately heading of 050 degrees. The cessna had apparently made a right 360 and crossed directly in front of our departure path. Had we not maneuvered out of his way, I feel we would have collided.

Title: NMAC IN THE TFC PATTERN. SMA LGT MIX.

Narrative: WHILE HOLDING IN POS FOR TKOF ON RWY 5R AT WILLOW RUN, THE TWR WAS WORKING A CESSNA 152 OR 172 IN CLOSED PATTERN ON RWY 27R. AS THE CESSNA TURNED DOWNWIND, TWR MADE REPEATED ATTEMPTS TO CALL. OTHER ACFT ANSWERED AND THERE WAS CONFUSION. THE CESSNA FINALLY RESPONDED AFTER HE PASSED BEYOND RWY 5R. HE WAS INSTRUCTED TO FLY EBOUND AND WE WERE CLRED FOR TKOF. I INSTRUCTED THE CREW AND 1 JUMPSEAT RIDER TO PAY CLOSE ATTN AS THERE WAS A LOT OF TFC. AFTER TKOF, THE COPLT AND JUMPSEAT RIDER ALERTED ME TO TFC 12 O'CLOCK, 1/4 MI, 300 FT ABOVE US. I PUSHED OVER AT APPROX 500 FT AGL AND STARTED A L TURN TO AVOID TFC, THE CESSNA THAT WAS ON DOWNWIND WAS IN A R TURN ON AN APPROX HDG OF 050 DEGS. THE CESSNA HAD APPARENTLY MADE A R 360 AND CROSSED DIRECTLY IN FRONT OF OUR DEP PATH. HAD WE NOT MANEUVERED OUT OF HIS WAY, I FEEL WE WOULD HAVE COLLIDED.
