# NTSB LAX01LA106: Ascher Yakolev YAK 11, N18AW, Ione, CA, February 27, 2001 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: February 27, 2001, 14:50 local (22:50 UTC) - Place: Ione, CA - Coordinates: 38.330898, -120.88076 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=38.3309&lon=-120.8808&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report November 6, 2001 - Report: Approved by Office Director - Parties: FAA Flt Stnds Dist Office - NTSB case key (mKey): 51829 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX01LA106 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/51829/pdf - Page: https://openairdocs.org/ntsb/LAX01LA106 ## Probable cause The failure of the pilot to maintain directional control during the takeoff run. A factor in the accident was the pilot's lack of total experience in the type aircraft. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - weather condition - crosswind - lack of total experience in type of aircraft, pilot in command (contributing factor) - directional control - not maintained, pilot in command (cause) ## Analysis During takeoff on the 100-foot-wide runway, the experimental racing airplane 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 pilot acquired the aircraft about 1 month before the accident and this was his first takeoff in it. There was a left, quartering crosswind at 16 knots with gusts to 22 knots. ## Factual narrative 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 feet 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. ## Aircraft - Registration: [N18AW](https://openairdocs.org/aircraft/N18AW), registered now, S/N 25-III-20, built 1954 (OpenAirDocs) - Reported make and model: Ascher Yakolev YAK 11 - Registry model: [Ward Ascher YAKOLEV YAK 11](https://openairdocs.org/model/ward-ascher-yakolev-yak-11) (registry code 05612KL) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-1830-94M2](https://openairdocs.org/engine/pratt-whitney-r-1830-94m2) (registry code 51636, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 25-111-20 - Airframe hours: 223 - Engines: P&W R-1830 1350 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: James A.

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.
