Narrative:

On rollout from a 3 point landing and about 10-15 mph the aircraft started to make an arc to the right. As I depressed the left rudder/brake the arc tightened to the right. To avoid hitting the culvert wall head on and possibly tipping over into the drainage ditch, I stepped very hard on the right brake to ground loop and stop. All went well until the left wing struck the culvert wall after about a 190 degree turn. Callback conversation with reporter revealed the following information: reporter states he does believe the culvert and also a ditch at the approach end of runway 20 are too close to the runway and could easily be moved further away to avoid problems if a landing goes bad. But the bottom line is that his aircraft was probably the problem. He believes that the left wheel is toed in just a bit. He discussed this with members of the ryan group he belongs to and no one really seemed to think it a problem. 2 other persons who flew his aircraft mentioned a pull on landing. Reporter has previously used a ground loop to solve a landing problem and feels it is usually a good procedure, but this time the culvert was in the way and it did not work out so well. In talking to the airport personnel he has learned that 7 aircraft have gone into the culvert over many yrs' time. The aircraft is currently being torn down and rebuilt.

Original NASA ASRS Text

Title: PLT FLYING A RYAN ST3KR HAS A LOSS OF CTL ON LNDG ROLL AND HEADS TOWARD CULVERT. TO AVOID HITTING THE CULVERT HEAD ON HE INTENTIONALLY GND LOOPS THE ACFT. L WING HITS CULVERT.

Narrative: ON ROLLOUT FROM A 3 POINT LNDG AND ABOUT 10-15 MPH THE ACFT STARTED TO MAKE AN ARC TO THE R. AS I DEPRESSED THE L RUDDER/BRAKE THE ARC TIGHTENED TO THE R. TO AVOID HITTING THE CULVERT WALL HEAD ON AND POSSIBLY TIPPING OVER INTO THE DRAINAGE DITCH, I STEPPED VERY HARD ON THE R BRAKE TO GND LOOP AND STOP. ALL WENT WELL UNTIL THE L WING STRUCK THE CULVERT WALL AFTER ABOUT A 190 DEG TURN. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE DOES BELIEVE THE CULVERT AND ALSO A DITCH AT THE APCH END OF RWY 20 ARE TOO CLOSE TO THE RWY AND COULD EASILY BE MOVED FURTHER AWAY TO AVOID PROBS IF A LNDG GOES BAD. BUT THE BOTTOM LINE IS THAT HIS ACFT WAS PROBABLY THE PROB. HE BELIEVES THAT THE L WHEEL IS TOED IN JUST A BIT. HE DISCUSSED THIS WITH MEMBERS OF THE RYAN GROUP HE BELONGS TO AND NO ONE REALLY SEEMED TO THINK IT A PROB. 2 OTHER PERSONS WHO FLEW HIS ACFT MENTIONED A PULL ON LNDG. RPTR HAS PREVIOUSLY USED A GND LOOP TO SOLVE A LNDG PROB AND FEELS IT IS USUALLY A GOOD PROC, BUT THIS TIME THE CULVERT WAS IN THE WAY AND IT DID NOT WORK OUT SO WELL. IN TALKING TO THE ARPT PERSONNEL HE HAS LEARNED THAT 7 ACFT HAVE GONE INTO THE CULVERT OVER MANY YRS' TIME. THE ACFT IS CURRENTLY BEING TORN DOWN AND REBUILT.
