Narrative:

While teaching unusual attitude recoveries to a student pilot, engine began running rough. I started to climb, turn towards airport and perform emergency checklist. Power dropped to 2100 RPM, and we overflew pxe airport at 6000 ft MSL. Crossed to the east, and began a descent into the 45 degree entry for runway 18. While announcing intentions, another aircraft reported a 3-4 mi final for runway 36. I told him we would be making a full stop on runway 18 due to a magneto failure. He went around and started left traffic for runway 18. On rollout, we heard another aircraft entering downwind for runway 36. To correct the situation, the non pilot unicom could have been more proactive in announcing active runway, and all pilots involved could have decided on runway 18 due to our problem with the aircraft.

Title: A LOW TIME CFI EXPERIENCED ENG TROUBLE WHILE TEACHING UNUSUAL ATTITUDE RECOVERY IN A 73AC. HE LANDED AT PXE ON RWY 18 AND WAS MAD THAT OTHER PEOPLE DIDN'T KNOW HE HAD A PROB.

Narrative: WHILE TEACHING UNUSUAL ATTITUDE RECOVERIES TO A STUDENT PLT, ENG BEGAN RUNNING ROUGH. I STARTED TO CLB, TURN TOWARDS ARPT AND PERFORM EMER CHKLIST. PWR DROPPED TO 2100 RPM, AND WE OVERFLEW PXE ARPT AT 6000 FT MSL. CROSSED TO THE E, AND BEGAN A DSCNT INTO THE 45 DEG ENTRY FOR RWY 18. WHILE ANNOUNCING INTENTIONS, ANOTHER ACFT RPTED A 3-4 MI FINAL FOR RWY 36. I TOLD HIM WE WOULD BE MAKING A FULL STOP ON RWY 18 DUE TO A MAGNETO FAILURE. HE WENT AROUND AND STARTED L TFC FOR RWY 18. ON ROLLOUT, WE HEARD ANOTHER ACFT ENTERING DOWNWIND FOR RWY 36. TO CORRECT THE SIT, THE NON PLT UNICOM COULD HAVE BEEN MORE PROACTIVE IN ANNOUNCING ACTIVE RWY, AND ALL PLTS INVOLVED COULD HAVE DECIDED ON RWY 18 DUE TO OUR PROB WITH THE ACFT.
