Narrative:

Early flight to practice short and soft field operations. My student and I were 1 hour into the flight when there were several arrs on the localizer runway 17 approach which resulted in some departure delays for aircraft waiting on the straight-in traffic. One citation jet reported a 6 mi final and my student and I successfully executed a soft-field takeoff and were off the runway and clear causing no problem to the arriving citation. 2 lndgs later, we were faced with another citation who reported a 4 mi final. I instructed my student to expedite his departure and perform yet another soft-field takeoff. There was some delay on my student's part, and we lost valuable seconds. We rolled onto the centerline and began the takeoff, but the citation had to execute a go around. The close call was completely my fault. I made a poor judgement call and endangered both crews and aircraft. The crews were french canadian and I felt that perhaps their unfamiliarity with the approach caused them to underestimate their distance out. It was I who underestimated the speed of the citation and made one of the poorest decisions in my flying career. If it were not for the skill of the crew, I feel there would have been a different outcome and far more to come of it than this report.

Title: AN INSTRUCTOR AND HIS STUDENT IN A PA28-161 AT LEESBURG, VA, RPT A CONFLICT WITH ANOTHER ACFT APCHING TO LAND ON THE OPPOSING END OF THE RWY THEY WERE PRACTICING LNDGS.

Narrative: EARLY FLT TO PRACTICE SHORT AND SOFT FIELD OPS. MY STUDENT AND I WERE 1 HR INTO THE FLT WHEN THERE WERE SEVERAL ARRS ON THE LOC RWY 17 APCH WHICH RESULTED IN SOME DEP DELAYS FOR ACFT WAITING ON THE STRAIGHT-IN TFC. ONE CITATION JET RPTED A 6 MI FINAL AND MY STUDENT AND I SUCCESSFULLY EXECUTED A SOFT-FIELD TKOF AND WERE OFF THE RWY AND CLR CAUSING NO PROB TO THE ARRIVING CITATION. 2 LNDGS LATER, WE WERE FACED WITH ANOTHER CITATION WHO RPTED A 4 MI FINAL. I INSTRUCTED MY STUDENT TO EXPEDITE HIS DEP AND PERFORM YET ANOTHER SOFT-FIELD TKOF. THERE WAS SOME DELAY ON MY STUDENT'S PART, AND WE LOST VALUABLE SECONDS. WE ROLLED ONTO THE CTRLINE AND BEGAN THE TKOF, BUT THE CITATION HAD TO EXECUTE A GAR. THE CLOSE CALL WAS COMPLETELY MY FAULT. I MADE A POOR JUDGEMENT CALL AND ENDANGERED BOTH CREWS AND ACFT. THE CREWS WERE FRENCH CANADIAN AND I FELT THAT PERHAPS THEIR UNFAMILIARITY WITH THE APCH CAUSED THEM TO UNDERESTIMATE THEIR DISTANCE OUT. IT WAS I WHO UNDERESTIMATED THE SPD OF THE CITATION AND MADE ONE OF THE POOREST DECISIONS IN MY FLYING CAREER. IF IT WERE NOT FOR THE SKILL OF THE CREW, I FEEL THERE WOULD HAVE BEEN A DIFFERENT OUTCOME AND FAR MORE TO COME OF IT THAN THIS RPT.
