Narrative:

During descent from dropping skydivers at 11000 ft MSL over the 3TE airport (tecumseh, mi), I was heading east and was advised of air carrier Y DC9 2-3 mi at my 4 O'clock position, also descending from 11000 ft. As that position was hidden by my wing, I began a turn to south, as the controller indicated that the DC9 would pass well in front of me on that heading. The DC9 was on a different approach frequency. After turning I was advised of the DC9 at 1 mi ahead and 500 ft below me, but in fact, I visually acquired it straight ahead and at my altitude. The DC9 was heading east and in a right bank, turning away from me. I immediately began a steep left turn away to the north, and advised approach that I had the traffic in sight. We separated and the traffic was no longer a factor. As I observed the DC9 in a climbing right turn, I assume that he may have had a TCASII RA, but as I did not hear any conversation between the DC9 and his controller, I am not sure. Contributing factors: references: L23 en route chart, panel C ec-1 approach charts. Cruxx 4 and mizar 2 stars. Yip traffic on cruxx 4 arrival and dtw traffic on mizar 2 arrival are routinely routed near or through the established drop zone at 3TE airport. While yip traffic is on our dtw frequency (118.95) dtw arrs are on a different frequency and may not be aware of our skydiving activities. Our skydiving aircraft (3 C182's) are routinely climbing and descending within 5 mi of 3TE airport, while yip arrs are routed directly through our climb and descent areas.

Title: A SKYDIVER C182 HAS A NEAR MISS WITH A DC9 MAKING A STAR ARR TO DTW, MI.

Narrative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
