Narrative:

My student and I departed the ash airport in a G109B motorglider. We proceeded swbound and were climbing out of 1500 ft when we saw an experimental skybolt, aerobatic biplane a few mi ahead of us. I asked the student to turn wbound and travel away from the biplane. After proceeding wbound and climbing through 2500 ft, I saw the biplane 1/4 mi off of our left wing. I took the plane and turned steeply to a northwest heading, turning us away from the biplane. I then saw the biplane behind us 300 ft away. I turned briskly to the left and so did the biplane. I entered a steep descent and a left turn to avoid the biplane, who was still 300 ft off of our tail. The aircraft followed. Finally, I made 1 more turn and descended again and the biplane broke off the pursuit. However, this final maneuver put me on the edge, partially in the ash class D airspace without 2-WAY radio communication being established. Pilots should not operate as careless and reckless as this pilot did. Aircraft are not toys and collision avoidance must be taken seriously!

Original NASA ASRS Text

Title: AN INSTRUCTOR AND STUDENT GLIDER PLT ENTERED ASH CLASS D AIRSPACE WITHOUT A CLRNC.

Narrative: MY STUDENT AND I DEPARTED THE ASH ARPT IN A G109B MOTORGLIDER. WE PROCEEDED SWBOUND AND WERE CLBING OUT OF 1500 FT WHEN WE SAW AN EXPERIMENTAL SKYBOLT, AEROBATIC BIPLANE A FEW MI AHEAD OF US. I ASKED THE STUDENT TO TURN WBOUND AND TRAVEL AWAY FROM THE BIPLANE. AFTER PROCEEDING WBOUND AND CLBING THROUGH 2500 FT, I SAW THE BIPLANE 1/4 MI OFF OF OUR L WING. I TOOK THE PLANE AND TURNED STEEPLY TO A NW HDG, TURNING US AWAY FROM THE BIPLANE. I THEN SAW THE BIPLANE BEHIND US 300 FT AWAY. I TURNED BRISKLY TO THE L AND SO DID THE BIPLANE. I ENTERED A STEEP DSCNT AND A L TURN TO AVOID THE BIPLANE, WHO WAS STILL 300 FT OFF OF OUR TAIL. THE ACFT FOLLOWED. FINALLY, I MADE 1 MORE TURN AND DSNDED AGAIN AND THE BIPLANE BROKE OFF THE PURSUIT. HOWEVER, THIS FINAL MANEUVER PUT ME ON THE EDGE, PARTIALLY IN THE ASH CLASS D AIRSPACE WITHOUT 2-WAY RADIO COM BEING ESTABLISHED. PLTS SHOULD NOT OPERATE AS CARELESS AND RECKLESS AS THIS PLT DID. ACFT ARE NOT TOYS AND COLLISION AVOIDANCE MUST BE TAKEN SERIOUSLY!
