Narrative:

I was flying as the glider tow pilot for the day at this uncontrolled airport. Because of airport regulations, the glider operations use runway 21/03 exclusively, although runways 31/13 are the generally preferred runways, with runway 31 being active on saturday. The glider operations were from runway 21. I had completed a tow and entered a left downwind for runway 21. There was a C152 making touch-and-goes on runway 31. As I reported downwind runway 21, he reported downwind for runway 31. We try to be good neighbors, so I let him know that I was going to extend my downwind, so he could do a touch and go before me. I extended, and after he reported base, I turned and reported base. He reported final, and I turned final. In retrospect, I should have realized that as a student, he was making excessively wide patterns. At any rate, as I approached, I realized that he was going to land about the same time I was. I considered going around, but as I was dragging the towline, I felt that there was a risk of interfering with him on his takeoff. Accordingly, I chose to land on runway 21. The geometry of the airport is that runway 31/13 intersects with runway 21 at about the last 1/4 of runway 21, and there was plenty of room for me to stop well short of runway 31. I suspect he never knew that a situation existed. However, if I had a brake failure, or any one of several other possible mechanical problems, there could have been a conflict. I will, in future events, go ahead and do a 360 degrees if there is any question of a conflict with traffic on runway 31. We usually coexist with ease and zero conflicts, but I cut this one too close. It is likely that I am the only person who noticed this near conflict, but I did notice it. I have also discussed this with other glider tow pilots.

Title: A C175 GLIDER TOW PLT LANDS WITH ANOTHER ACFT ON AN INTERSECTING RWY.

Narrative: I WAS FLYING AS THE GLIDER TOW PLT FOR THE DAY AT THIS UNCTLED ARPT. BECAUSE OF ARPT REGS, THE GLIDER OPS USE RWY 21/03 EXCLUSIVELY, ALTHOUGH RWYS 31/13 ARE THE GENERALLY PREFERRED RWYS, WITH RWY 31 BEING ACTIVE ON SATURDAY. THE GLIDER OPS WERE FROM RWY 21. I HAD COMPLETED A TOW AND ENTERED A L DOWNWIND FOR RWY 21. THERE WAS A C152 MAKING TOUCH-AND-GOES ON RWY 31. AS I RPTED DOWNWIND RWY 21, HE RPTED DOWNWIND FOR RWY 31. WE TRY TO BE GOOD NEIGHBORS, SO I LET HIM KNOW THAT I WAS GOING TO EXTEND MY DOWNWIND, SO HE COULD DO A TOUCH AND GO BEFORE ME. I EXTENDED, AND AFTER HE RPTED BASE, I TURNED AND RPTED BASE. HE RPTED FINAL, AND I TURNED FINAL. IN RETROSPECT, I SHOULD HAVE REALIZED THAT AS A STUDENT, HE WAS MAKING EXCESSIVELY WIDE PATTERNS. AT ANY RATE, AS I APCHED, I REALIZED THAT HE WAS GOING TO LAND ABOUT THE SAME TIME I WAS. I CONSIDERED GOING AROUND, BUT AS I WAS DRAGGING THE TOWLINE, I FELT THAT THERE WAS A RISK OF INTERFERING WITH HIM ON HIS TKOF. ACCORDINGLY, I CHOSE TO LAND ON RWY 21. THE GEOMETRY OF THE ARPT IS THAT RWY 31/13 INTERSECTS WITH RWY 21 AT ABOUT THE LAST 1/4 OF RWY 21, AND THERE WAS PLENTY OF ROOM FOR ME TO STOP WELL SHORT OF RWY 31. I SUSPECT HE NEVER KNEW THAT A SIT EXISTED. HOWEVER, IF I HAD A BRAKE FAILURE, OR ANY ONE OF SEVERAL OTHER POSSIBLE MECHANICAL PROBS, THERE COULD HAVE BEEN A CONFLICT. I WILL, IN FUTURE EVENTS, GO AHEAD AND DO A 360 DEGS IF THERE IS ANY QUESTION OF A CONFLICT WITH TFC ON RWY 31. WE USUALLY COEXIST WITH EASE AND ZERO CONFLICTS, BUT I CUT THIS ONE TOO CLOSE. IT IS LIKELY THAT I AM THE ONLY PERSON WHO NOTICED THIS NEAR CONFLICT, BUT I DID NOTICE IT. I HAVE ALSO DISCUSSED THIS WITH OTHER GLIDER TOW PLTS.
