Narrative:
This day around XA30, my student and I are taking off from ads on a beechcraft BE19 sport 180 for hqz. I decided then to let him go for his second supervised solo which consists of 3 takeoffs and lndgs to a full stop. After all the lndgs we practiced together (64), and also the first supervised solo flight he did the day before, I'm feeling really confident to let him go solo for a second time. So I put an endorsement in his logbook and get off the airplane in hqz. The airplane starts taxiing to the runway 35, gets into position, starts the takeoff and gets airborne. The first traffic pattern seems quite nice, until he gets to final. On final the airplane is too high. Pitching down to get down to the runway, the airspeed is increasing which makes the flare more difficult. The airplane touches down and bounces 2 times. My student decides then to go around and the airplane takes off once again for another turn. The 2ND traffic pattern is good until, once again, the plane gets on final. On final, the airplane is still too high so the same problem happens again: too much airspeed on the flare. But this time, my student flares pretty well, letting the airspeed decrease. The airplane bounces once again, but just a little. The student then adds just enough power to get the plane to a better position. The engine shut down, the propeller is intact. Just the left main gear is cracked, but it didn't collapse. I think that after the touchdown, my student didn't keep enough back pressure on the yoke, letting the airplane wheelbarrow. To try to correct the situation, the student has, then, used the brakes. But with more weight on the right main gear and less on the left, the use of the brakes has resulted in creating a differential braking action, making the airplane abruptly go to the right. While seeing the airplane going toward the grass, the student then pulled the mixture to idle cut off and stopped the engine. That action actually saved the airplane and its pilot. When looking backward to this incident, which could have been worse, I can tell that there was here at least 3 important mistakes at the origin of the incident: I, as the flight instructor supervising the solo and obviously responsible for it, shouldn't let the student go solo after just one landing. Even if the student has demonstrated really good performances on lndgs, I shouldn't have been so confident and done at least a couple of lndgs more with him that day. The student released the back pressure on the yoke while the rollout wasn't finished. A landing is not finished until the airplane has stopped or gets airborne. The student has applied the brakes while wheelbarrowing, instead of, for instance, having put the flaps in the up position and reapplied the back pressure on the yoke. During the landing, the pilot should avoid putting his feet on the brakes: the heels should stay on the floor. Supplemental information from acn 393006: the airplane bounced once so I set a little power to align it again, then took off power and touched down the runway with the main landing gear and started settle down on the 3 wheels. Because I was too fast I tried to slow the airplane by putting brake pressure and it skidded to the right in an angle of about 80 degrees. When I got into the grass on the side, I cut the mixture and shut down the engine, and stop the plane by brakes. Once it stopped I shut down all electrical system and got off the plane.

Title: AN INSTRUCTOR AND STUDENT PLT RPT THE STUDENT'S MISADVENTURE WITH A BE19 THAT DEPARTS THE RWY DURING THE LNDG ROLLOUT. THE STUDENT WAS ON A SUPERVISED SOLO FLT.
Narrative: THIS DAY AROUND XA30, MY STUDENT AND I ARE TAKING OFF FROM ADS ON A BEECHCRAFT BE19 SPORT 180 FOR HQZ. I DECIDED THEN TO LET HIM GO FOR HIS SECOND SUPERVISED SOLO WHICH CONSISTS OF 3 TKOFS AND LNDGS TO A FULL STOP. AFTER ALL THE LNDGS WE PRACTICED TOGETHER (64), AND ALSO THE FIRST SUPERVISED SOLO FLT HE DID THE DAY BEFORE, I'M FEELING REALLY CONFIDENT TO LET HIM GO SOLO FOR A SECOND TIME. SO I PUT AN ENDORSEMENT IN HIS LOGBOOK AND GET OFF THE AIRPLANE IN HQZ. THE AIRPLANE STARTS TAXIING TO THE RWY 35, GETS INTO POS, STARTS THE TKOF AND GETS AIRBORNE. THE FIRST TFC PATTERN SEEMS QUITE NICE, UNTIL HE GETS TO FINAL. ON FINAL THE AIRPLANE IS TOO HIGH. PITCHING DOWN TO GET DOWN TO THE RWY, THE AIRSPD IS INCREASING WHICH MAKES THE FLARE MORE DIFFICULT. THE AIRPLANE TOUCHES DOWN AND BOUNCES 2 TIMES. MY STUDENT DECIDES THEN TO GAR AND THE AIRPLANE TAKES OFF ONCE AGAIN FOR ANOTHER TURN. THE 2ND TFC PATTERN IS GOOD UNTIL, ONCE AGAIN, THE PLANE GETS ON FINAL. ON FINAL, THE AIRPLANE IS STILL TOO HIGH SO THE SAME PROB HAPPENS AGAIN: TOO MUCH AIRSPD ON THE FLARE. BUT THIS TIME, MY STUDENT FLARES PRETTY WELL, LETTING THE AIRSPD DECREASE. THE AIRPLANE BOUNCES ONCE AGAIN, BUT JUST A LITTLE. THE STUDENT THEN ADDS JUST ENOUGH PWR TO GET THE PLANE TO A BETTER POS. THE ENG SHUT DOWN, THE PROP IS INTACT. JUST THE L MAIN GEAR IS CRACKED, BUT IT DIDN'T COLLAPSE. I THINK THAT AFTER THE TOUCHDOWN, MY STUDENT DIDN'T KEEP ENOUGH BACK PRESSURE ON THE YOKE, LETTING THE AIRPLANE WHEELBARROW. TO TRY TO CORRECT THE SIT, THE STUDENT HAS, THEN, USED THE BRAKES. BUT WITH MORE WT ON THE R MAIN GEAR AND LESS ON THE L, THE USE OF THE BRAKES HAS RESULTED IN CREATING A DIFFERENTIAL BRAKING ACTION, MAKING THE AIRPLANE ABRUPTLY GO TO THE R. WHILE SEEING THE AIRPLANE GOING TOWARD THE GRASS, THE STUDENT THEN PULLED THE MIXTURE TO IDLE CUT OFF AND STOPPED THE ENG. THAT ACTION ACTUALLY SAVED THE AIRPLANE AND ITS PLT. WHEN LOOKING BACKWARD TO THIS INCIDENT, WHICH COULD HAVE BEEN WORSE, I CAN TELL THAT THERE WAS HERE AT LEAST 3 IMPORTANT MISTAKES AT THE ORIGIN OF THE INCIDENT: I, AS THE FLT INSTRUCTOR SUPERVISING THE SOLO AND OBVIOUSLY RESPONSIBLE FOR IT, SHOULDN'T LET THE STUDENT GO SOLO AFTER JUST ONE LNDG. EVEN IF THE STUDENT HAS DEMONSTRATED REALLY GOOD PERFORMANCES ON LNDGS, I SHOULDN'T HAVE BEEN SO CONFIDENT AND DONE AT LEAST A COUPLE OF LNDGS MORE WITH HIM THAT DAY. THE STUDENT RELEASED THE BACK PRESSURE ON THE YOKE WHILE THE ROLLOUT WASN'T FINISHED. A LNDG IS NOT FINISHED UNTIL THE AIRPLANE HAS STOPPED OR GETS AIRBORNE. THE STUDENT HAS APPLIED THE BRAKES WHILE WHEELBARROWING, INSTEAD OF, FOR INSTANCE, HAVING PUT THE FLAPS IN THE UP POS AND REAPPLIED THE BACK PRESSURE ON THE YOKE. DURING THE LNDG, THE PLT SHOULD AVOID PUTTING HIS FEET ON THE BRAKES: THE HEELS SHOULD STAY ON THE FLOOR. SUPPLEMENTAL INFO FROM ACN 393006: THE AIRPLANE BOUNCED ONCE SO I SET A LITTLE PWR TO ALIGN IT AGAIN, THEN TOOK OFF PWR AND TOUCHED DOWN THE RWY WITH THE MAIN LNDG GEAR AND STARTED SETTLE DOWN ON THE 3 WHEELS. BECAUSE I WAS TOO FAST I TRIED TO SLOW THE AIRPLANE BY PUTTING BRAKE PRESSURE AND IT SKIDDED TO THE R IN AN ANGLE OF ABOUT 80 DEGS. WHEN I GOT INTO THE GRASS ON THE SIDE, I CUT THE MIXTURE AND SHUT DOWN THE ENG, AND STOP THE PLANE BY BRAKES. ONCE IT STOPPED I SHUT DOWN ALL ELECTRICAL SYS AND GOT OFF THE PLANE.
