# NTSB LAX00LA252: Cessna 152, N6439M, Oakland, CA, July 6, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 6, 2000, 11:30 local (18:30 UTC) - Place: Oakland, CA - Location: 37.7213° N, 122.2212° W: Placed by OpenAirDocs at OAKLAND SAN FRANCISCO BAY (OAK), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=37.7213&lon=-122.2212&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 17, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49626 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX00LA252 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49626/pdf - Page: https://openairdocs.org/ntsb/LAX00LA252 ## Probable cause failure of the instructor to adequately supervise the student, resulting in a loss of directional control. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - weather condition - crosswind (contributing factor) - touch-and-go - initiated, dual student - compensation for wind conditions - inadequate, dual student (cause) - instructions,written/verbal - not complied with, dual student (cause) - directional control - not maintained, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) - On ground/water collision with object, takeoff - object - runway light ## Analysis Touch-and-go landings were being practiced, and the winds were variable. After power was added and the airplane was accelerating, the instructor noticed the student was not compensating for torque or crosswind. The instructor prompted the student to add right rudder, but the student reacted quickly with left rudder and brake. The instructor pulled power but did not want to make aggressive control inputs due to the airplane's speed. The airplane veered left, departed the runway, hit a runway light, and the nose gear collapsed. ## Factual narrative On July 6, 2000, about 1130 hours Pacific daylight time, a Cessna 152, N6439M, sustained substantial damage when it veered off the runway and collided with a runway light during a touch-and-go on runway 27L at the Metropolitan Oakland International Airport, Oakland, California. Sierra Academy of Aeronautics Technical Institute was operating the airplane under the provisions of 14 CFR Part 91. The certified flight instructor pilot and one student were not injured. The local instructional flight departed Oakland about 1030. Visual meteorological conditions prevailed and no flight plan was filed. The operator reported touch-and-go landings were practiced for approximately 1 hour, and the winds were variable. After power was added and the airplane was accelerating, the instructor noticed the student was not compensating for torque or crosswind. The instructor prompted the student to add right rudder, but the student reacted quickly with left rudder and brake. The instructor, who assumed control, pulled power but did not want to make aggressive control inputs due to the airplane's speed. The airplane veered left, departed the runway, and hit a runway light. The nose gear collapsed and the firewall buckled. ## Aircraft - Registration: [N6439M](https://openairdocs.org/deregistered/N6439M-2013-08-05), registration cancelled 2013-08-05, S/N 15284727, built 1980 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 15284727 - Airframe hours: 15157 - Engines: Lycoming O-235-L2C 110 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Sierra Academy Of Aeronautics - Registered owner: Christensen Aviation, Inc. - Airworthiness certificate: Standard, Utility - Last inspection: AAIP, July 1, 2000, 5 hours before - Departed: OAK - Airport: OAK, Oakland International, runway 27L, 6,212 × 150 ft, asphalt ## Flight crew As NTSB recorded them.

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.
