From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) As the a/c slowly started to accelerate it veered to the right until both wheel exited the runway surface. The airline straightened out and taxied down a small ravine to the right of the runway. After a few seconds, the pilot chopped the throttle just as the a/c hit an elevator taxiway that lies perpendicular to the runway. The airplane bounced from the right to the left side of the runway, srriking the propeller on the FAR side of a canal. The a/c spun 180 degrees and came to rest. (.4) on February 27, 2001, at 1450 hours pacific standard time, an experimental ascher yak 11, N18AW, was substantially damaged when the aircraft veered off the runway and impacted a berm during takeoff at eagle's nest Private Airport, Ione, California. The airline transport certificated pilot, the sole occupant, received minor injuries. The personal flight was operated by the pilot/owner under 14 CFR part 91, and was destined for santa rosa, California. Visual meteorological conditions prevailed and no flight plan was filed. According to a federal aviation administration inspector, witnesses reported that, during takeoff on runway 1 (paved, 4,000 feet long x 100 fee t wide), the aircraft drifted to the right-hand edge of the runway and then continued off the runway until it struck a berm at the midfield taxiway. Impact with the berm damaged the landing gear and deflected the aircraft to the left and into the air where it traveled back across the runway (airborne). The airplane came to rest in the dirt on the left side of the runway about 3,000 feet from the start of the takeoff roll. The single-seat aircraft, modified for air racing, was assembled from U.S. And russian aircraft components. The airframe was a russian-built yakolev yak 11, and the engine a U.S.-built pratt & whitney R-1830. The pilot acquired the aircraft about 1 month before the accident and this was his first takeoff in it. The surface wind at mather field, 16 miles northwest of the accident site, was reported from 320 degrees at 16 knots with gusts to 22 knots.

As the FAA filed it

(-23) AS THE A/C SLOWLY STARTED TO ACCELERATE IT VEERED TO THE RIGHT UNTIL BOTH WHEEL EXITED THE RUNWAY SURFACE. THE AIRLINE STRAIGHTENED OUT AND TAXIED DOWN A SMALL RAVINE TO THE RIGHT OF THE RUNWAY. AFTER A FEW SECONDS, THE PILOT CHOPPED THE THROTTLE JUST AS THE A/C HIT AN ELEVATOR TAXIWAY THAT LIES PERPENDICULAR TO THE RUNWAY. THE AIRPLANE BOUNCED FROM THE RIGHT TO THE LEFT SIDE OF THE RUNWAY, SRRIKING THE PROPELLER ON THE FAR SIDE OF A CANAL. THE A/C SPUN 180 DEGREES AND CAME TO REST. (.4) ON FEBRUARY 27, 2001, AT 1450 HOURS PACIFIC STANDARD TIME, AN EXPERIMENTAL ASCHER YAK 11, N18AW, WAS SUBSTANTIALLY DAMAGED WHEN THE AIRCRAFT VEERED OFF THE RUNWAY AND IMPACTED A BERM DURING TAKEOFF AT EAGLE'S NEST PRIVATE AIRPORT, IONE, CALIFORNIA. THE AIRLINE TRANSPORT CERTIFICATED PILOT, THE SOLE OCCUPANT, RECEIVED MINOR INJURIES. THE PERSONAL FLIGHT WAS OPERATED BY THE PILOT/OWNER UNDER 14 CFR PART 91, AND WAS DESTINED FOR SANTA ROSA, CALIFORNIA. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AND NO FLIGHT PLAN WAS FILED. ACCORDING TO A FEDERAL AVIATION ADMINISTRATION INSPECTOR, WITNESSES REPORTED THAT, DURING TAKEOFF ON RUNWAY 1 (PAVED, 4,000 FEET LONG X 100 FEE T WIDE), THE AIRCRAFT DRIFTED TO THE RIGHT-HAND EDGE OF THE RUNWAY AND THEN CONTINUED OFF THE RUNWAY UNTIL IT STRUCK A BERM AT THE MIDFIELD TAXIWAY. IMPACT WITH THE BERM DAMAGED THE LANDING GEAR AND DEFLECTED THE AIRCRAFT TO THE LEFT AND INTO THE AIR WHERE IT TRAVELED BACK ACROSS THE RUNWAY (AIRBORNE). THE AIRPLANE CAME TO REST IN THE DIRT ON THE LEFT SIDE OF THE RUNWAY ABOUT 3,000 FEET FROM THE START OF THE TAKEOFF ROLL. THE SINGLE-SEAT AIRCRAFT, MODIFIED FOR AIR RACING, WAS ASSEMBLED FROM U.S. AND RUSSIAN AIRCRAFT COMPONENTS. THE AIRFRAME WAS A RUSSIAN-BUILT YAKOLEV YAK 11, AND THE ENGINE A U.S.-BUILT PRATT & WHITNEY R-1830.
