THE LEFT WING WAS SUBSTANTIALLY DAMAGED. (.4) THE PILOT STATED THAT HE WAS GOING TO PERFORM TOUCH-AND-GO LANDINGS FOLLOWING REPLACEMENT OF THE NOSE LANDING GEAR MICRO SWITCH 2 DAYS EARLIER. RUNWAY 14 WAS THE RUNWAY IN USE DUE TO A DISABLED AIRPLANE ON RUNWAY 23. AFT ER TAKEOFF THE FLIGHT REMAINED IN THE TRAFFIC PATTERN; THE WIND WAS FROM 230 DEGREES AT 7 KNOTS. THE LANDING GEAR WAS EXTENDED ON THE DOWNWIND LEG; ALL GEARS WERE CONFIRMED DOWN BY GEAR INDICATOR LIGHTS. THE FLIGHT TURNED BASE THEN FINAL AND LANDED WITH FULL FLAPS FIRST ON THE RIGHT MAIN LANDING GEAR FOLLOWED BY THE LEFT MAIN THEN NOSE LANDING GEAR. DURING THE LANDING ROLL WITH FULL RIGHT AILERON INPUT AND SLIGHT LEFT RUDDER INPUT, THE RIGHT WING RAISED AND THE AIRPLANE VEERED TO THE LEFT. THE PILOT ADDED FULL POWER AND RIGHT RUDDER INPUT BUT COULDN'T RECALL IF HE ADDED FULL RIGHT RUDDER. THE AIRPLANE "STARTED TO SLEW HARDER TO THE LEFT", AND HE THEN REDUCED POWER, AND APPLIED THE BRAKES "AND THE FLIGHT CONTROLS" WITH NO EFFECT. THE AIRPLANE DEPARTED THE LEFT SIDE OF THE RUNWAY, IMPACTED ON THE UPSLOPE OF A DRAINAGE DITCH, AND CAME TO REST PAST A DRAINAGE DITCH WITH THE NOSE LANDING GEAR SHEARED AND THE LEFT MAIN LANDING GEAR COLLAPSED; THE RIGHT MAIN LANDING GEAR REMAINED EXTENDED. A CFI IN THE AIRPLANE CONFIRMED THAT ALL GEARS WERE DOWN AND LOCKED ON FINAL APPROACH AS INDICATED BY 3 GREEN LIGHTS AND THE PILOT LANDED FIRST ON THE RIGHT MAIN LANDING GEAR WHICH FELT SOLID.

THERE WAS NO EVIDENCE OF PROPELLER CONTACT ON THE RUNWAY; PROPELLER CONTACT WAS NOTED IN THE SOFT GROUND OF THE RAVINE AREA. ADDITIONALLY, MARKS IN THE GRASS WERE NOTED FROM ONE OF THE MAIN LANDING GEARS AND THE NOSE LANDING GEAR. POST ACCIDENT TESTING OF THE LEFT AND RIGHT MAIN LANDING GEARS BY AN FAA AIRWORTHINESS INSPECTOR REVEALED NO EVIDENCE OF FAILURE OR MALFUNCTION. THE DOWNLOCK RIGGING WAS CORRECT, BOTH DOWNLOCKS PERFORMED AS REQUIRED, AND THE SQUAT SWITCHES WERE RIGGED CORRECTLY AND FUNCTIONAL.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB MIA01LA174](https://openairdocs.org/ntsb/MIA01LA174), Jun 23, 2001: Socata TB-20 (N1887S), Naples, FL, substantial damage.
