What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 08/17/2011, NTSB investigator privacy data omitted was contacted by the owner of aircraft N284E, from (H49), Sackman Field in Columbia, IL. He was informed that at approximately 1745 local time, the aircraft experienced a loss of control on the roll out after the third landing of the day. The aircraft came to rest in a cornfield adjacent to the grass runway 03/21, landing 21. No injuries were reported to the two crewmembers. Pilot in command: privacy data omittedCFI privacy data omittedthe aircraft is a homebuilt experimental jabiru SP170. Registration number N284E.the aircraft is based at Columbia, Illinois airport H49 in hangar 21. The aircraft is registered as an "experimental" aircraft and is made of all composite material except for the main landing gear strut and the wing struts. Those items are made of aluminum and alloy. This event is categorized as an accident due to: the left wing struck the ground and acted in a manner as to support the entire weight of the aircraft, occupants and gravitational forces. The total forces exerted on the left wing possibly caused metal fatigue/stretching/cracking of the main spar and wing attachment points. The left wing displacement caused the composite skin to delaminate near the fuselage from 10 inches behind the leading edge, extending aft to the trailing edge. This delamination was very noticeable during the examination of the aircraft. First noticed, was that the right main landing gear wheel was off of the aircraft. The wheel was lost from the aircraft on landing roll out. After the aircraft wheel departed the airframe, the wheel strut and spindle began dragging the ground, creating an unrecoverable right arcing turn towards the west, off the runway and into an adjacent cornfield. The aircraft exited the runway to the right after landing approximately 1,330 feet down the runway from the arrival end of runway 21. The aircraft touched down at 530 feet from the runway end of runway 21. The aircraft lost the right main landing gear wheel at approximately 600 feet after touchdown. The aircraft then made a right sweeping turn, uncontrolled, off the right side of the runway, through a small shallow ditch, and came to rest approximately 12 feet into the adjacent cornfield. Substantial damage to the landing gear was noted, due to the impact with the small shallow ditch. The nose gear separated from the airframe. The engine propeller contacted the ditch. The engine encountered a sudden stoppage and major damage to the propeller was done. The propeller was damaged up to 10 inches from the blade tip on both blades. The left main landing gear was broken from the support structure, but still attached to the aircraft. The right main landing gear was intact, but loose in its near correct position. The wheel/tire assembly and the brake assembly were both severely damaged as the wheel came off the airframe and the brake assembly was ripped from the main landing gear strut. The right wing had no visible damage. The left wing sustained visible damage to the wing attachment point near the fuselage. The left wing had delaminated on the trailing edge near the fuselage.
As the FAA filed it
ON 08/17/2011, NTSB INVESTIGATOR ^PRIVACY DATA OMITTED^ WAS CONTACTED BY THE OWNER OF AIRCRAFT N284E, FROM (H49), SACKMAN FIELD IN COLUMBIA, IL. HE WAS INFORMED THAT AT APPROXIMATELY 1745 LOCAL TIME, THE AIRCRAFT EXPERIENCED A LOSS OF CONTROL ON THE ROLL OUT AFTER THE THIRD LANDING OF THE DAY. THE AIRCRAFT CAME TO REST IN A CORNFIELD ADJACENT TO THE GRASS RUNWAY 03/21, LANDING 21. NO INJURIES WERE REPORTED TO THE TWO CREWMEMBERS.PILOT IN COMMAND: ^PRIVACY DATA OMITTED^CFI ^PRIVACY DATA OMITTED^THE AIRCRAFT IS A HOMEBUILT EXPERIMENTAL JABIRU SP170. REGISTRATION NUMBER N284E.THE AIRCRAFT IS BASED AT COLUMBIA, ILLINOIS AIRPORT H49 IN HANGAR 21. THE AIRCRAFT IS REGISTERED AS AN "EXPERIMENTAL" AIRCRAFT AND IS MADE OF ALL COMPOSITE MATERIAL EXCEPT FOR THE MAIN LANDING GEAR STRUT AND THE WING STRUTS. THOSE ITEMS ARE MADE OF ALUMINUM AND ALLOY.THIS EVENT IS CATEGORIZED AS AN ACCIDENT DUE TO: THE LEFT WING STRUCK THE GROUND AND ACTED IN A MANNER AS TO SUPPORT THE ENTIRE WEIGHT OF THE AIRCRAFT, OCCUPANTS AND GRAVITATIONAL FORCES. THE TOTAL FORCES EXERTED ON THE LEFT WING POSSIBLY CAUSED METAL FATIGUE/STRETCHING/CRACKING OF THE MAIN SPAR AND WING ATTACHMENT POINTS. THE LEFT WING DISPLACEMENT CAUSED THE COMPOSITE SKIN TO DELAMINATE NEAR THE FUSELAGE FROM 10 INCHES BEHIND THE LEADING EDGE, EXTENDING AFT TO THE TRAILING EDGE. THIS DELAMINATION WAS VERY NOTICEABLE DURING THE EXAMINATION OF THE AIRCRAFT.FIRST NOTICED, WAS THAT THE RIGHT MAIN LANDING GEAR WHEEL WAS OFF OF THE AIRCRAFT. THE WHEEL WAS LOST FROM THE AIRCRAFT ON LANDING ROLL OUT. AFTER THE AIRCRAFT WHEEL DEPARTED THE AIRFRAME, THE WHEEL STRUT AND SPINDLE BEGAN DRAGGING THE GROUND, CREATING AN UNRECOVERABLE RIGHT ARCING TURN TOWARDS THE WEST, OFF THE RUNWAY AND INTO AN ADJACENT CORNFIELD. THE AIRCRAFT EXITED THE RUNWAY TO THE RIGHT AFTER LANDING APPROXIMATELY 1,330 FEET DOWN THE RUNWAY FROM THE ARRIVAL END OF RUNWAY 21. THE AIRCRAFT TOUCHED DOWN AT 530 FEET FROM THE RUNWAY END OF RUNWAY 21. THE AIRCRAFT LOST THE RIGHT MAIN LANDING GEAR WHEEL AT APPROXIMATELY 600 FEET AFTER TOUCHDOWN. THE AIRCRAFT THEN MADE A RIGHT SWEEPING TURN, UNCONTROLLED, OFF THE RIGHT SIDE OF THE RUNWAY, THROUGH A SMALL SHALLOW DITCH, AND CAME TO REST APPROXIMATELY 12 FEET INTO THE ADJACENT CORNFIELD. SUBSTANTIAL DAMAGE TO THE LANDING GEAR WAS NOTED, DUE TO THE IMPACT WITH THE SMALL SHALLOW DITCH. THE NOSE GEAR SEPARATED FROM THE AIRFRAME. THE ENGINE PROPELLER CONTACTED THE DITCH. THE ENGINE ENCOUNTERED A SUDDEN STOPPAGE AND MAJOR DAMAGE TO THE PROPELLER WAS DONE. THE PROPELLER WAS DAMAGED UP TO 10 INCHES FROM THE BLADE TIP ON BOTH BLADES. THE LEFT MAIN LANDING GEAR WAS BROKEN FROM THE SUPPORT STRUCTURE, BUT STILL ATTACHED TO THE AIRCRAFT. THE RIGHT MAIN LANDING GEAR WAS INTACT, BUT LOOSE IN ITS NEAR CORRECT POSITION. THE WHEEL/TIRE ASSEMBLY AND THE BRAKE ASSEMBLY WERE BOTH SEVERELY DAMAGED AS THE WHEEL CAME OFF THE AIRFRAME AND THE BRAKE ASSEMBLY WAS RIPPED FROM THE MAIN LANDING GEAR STRUT. THE RIGHT WING HAD NO VISIBLE DAMAGE. THE LEFT WING SUSTAINED VISIBLE DAMAGE TO THE WING ATTACHMENT POINT NEAR THE FUSELAGE. THE LEFT WING HAD DELAMINATED ON THE TRAILING EDGE NEAR THE FUSELAGE.
