Narrative:

Training lesson in C-152. The plan was to learn to track the VOR to ela, then do lndgs to a full stop so the student got some traffic pattern practice, taxi practice, and takeoff practice. After tracking to the VOR at ela from 5ta4, we turned left on an upwind, for runway 17 at ela, crossed the runway to look at the windsock, then entered left downwind at 45 degrees for runway 17, then started landing sequence, base and final, putting in full flaps on final. The windsock was limp. The understanding was that the student was to 'feel' the controls but let me do the landing. The landing was smooth, slightly left of center. Rollout started out normal, then, after a short distance, the plane veered to the left, ran off the runway. I immediately put in right rudder, eventually to the floor, but the plane continued across the grassy area. The nosewheel went into a muddy ditch, the tail came up, hesitated at the top for a moment, and fell on its back. The time was very short from touchdown to the ditch. I could not determine why the plane would not respond to the rudder and did everything I could to keep the plane from veering off the runway into the ditch. Luckily, the student only had minor injuries and I had none.

Title: RWY EXCURSION AFTER LOSS OF ACFT CTL. ACFT DAMAGED.

Narrative: TRAINING LESSON IN C-152. THE PLAN WAS TO LEARN TO TRACK THE VOR TO ELA, THEN DO LNDGS TO A FULL STOP SO THE STUDENT GOT SOME TFC PATTERN PRACTICE, TAXI PRACTICE, AND TKOF PRACTICE. AFTER TRACKING TO THE VOR AT ELA FROM 5TA4, WE TURNED L ON AN UPWIND, FOR RWY 17 AT ELA, CROSSED THE RWY TO LOOK AT THE WINDSOCK, THEN ENTERED L DOWNWIND AT 45 DEGS FOR RWY 17, THEN STARTED LNDG SEQUENCE, BASE AND FINAL, PUTTING IN FULL FLAPS ON FINAL. THE WINDSOCK WAS LIMP. THE UNDERSTANDING WAS THAT THE STUDENT WAS TO 'FEEL' THE CTLS BUT LET ME DO THE LNDG. THE LNDG WAS SMOOTH, SLIGHTLY L OF CTR. ROLLOUT STARTED OUT NORMAL, THEN, AFTER A SHORT DISTANCE, THE PLANE VEERED TO THE L, RAN OFF THE RWY. I IMMEDIATELY PUT IN R RUDDER, EVENTUALLY TO THE FLOOR, BUT THE PLANE CONTINUED ACROSS THE GRASSY AREA. THE NOSEWHEEL WENT INTO A MUDDY DITCH, THE TAIL CAME UP, HESITATED AT THE TOP FOR A MOMENT, AND FELL ON ITS BACK. THE TIME WAS VERY SHORT FROM TOUCHDOWN TO THE DITCH. I COULD NOT DETERMINE WHY THE PLANE WOULD NOT RESPOND TO THE RUDDER AND DID EVERYTHING I COULD TO KEEP THE PLANE FROM VEERING OFF THE RWY INTO THE DITCH. LUCKILY, THE STUDENT ONLY HAD MINOR INJURIES AND I HAD NONE.
