# NTSB LAX93LA293: Aviat A-1, N9614L, Selma, CA, July 20, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 20, 1993, 14:50 local (21:50 UTC) - Place: Selma, CA - Coordinates: 36.52972, -119.640861 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.5297&lon=-119.6409&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report August 1, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 28430 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX93LA293 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/28430/pdf - Page: https://openairdocs.org/ntsb/LAX93LA293 ## Probable cause the pilot-in-command's failure to maintain direction control, inadequate compensation for the existing wind conditions, and improper use of the rudder. The pilot's lack of total experience in the accident airplane make and model is a factor in this accident. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command (cause) - compensation for wind conditions - inadequate, pilot in command (cause) - Loss of control - on ground/water, landing - aborted - rudder - improper use of, pilot in command (cause) - lack of total experience in type of aircraft, pilot in command (contributing factor) - Main gear collapsed, landing - aborted - landing gear - overload ## Analysis THE COMMERCIAL PILOT HAD RECEIVED 4.6 HOURS OF DUAL INSTRUCTION IN THE CONVENTIONAL GEAR AIRPLANE. ON THE FIRST SOLO FLIGHT, THE PILOT EXECUTED TWO LANDINGS WITHOUT INCIDENT. ON THE THIRD LANDING THE PILOT LOST CONTROL OF THE AIRPLANE AND ADDED FULL POWER, BUT THE AIRPLANE EXITED THE LEFT SIDE OF THE RUNWAY AND DAMAGED THE RIGHT MAIN LANDING GEAR. THERE WAS LESS THAN 2-KNOTS EFFECTIVE CROSSWIND COMPONENT EXISTING AT THE TIME. ## Factual narrative On July 20, 1993, at 1450 hours Pacific daylight time, an Aviat A-1, N9614L, exited the left side of runway 28 at Selma Airport, Selma, California, and collapsed the right main landing gear. The pilot was conducting a local visual flight rules personal flight and was practicing touch and go takeoffs and landings. The airplane, registered to and operated by the pilot, sustained substantial damage. The certificated private pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight departed Selma Airport at 1445 hours. A Federal Aviation Administration (FAA) airworthiness inspector reported that on the third touch and go landing the airplane began to veer to the left. The pilot added full power and began to takeoff, but the airplane continued to veer to the left and exited the runway. The right main landing gear collapsed when the airplane entered the rough terrain. The pilot reported in the Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1/2, that he had received four and a half (4 1/2) hours of dual instruction before beginning the accident flight. He completed two (2) full-stop landings without incident; on the third landing he stated, ". . . I reacted incorrectly to the wind and the aircraft left the runway and ran into a dirt bank at approximately 15 - 20 mph (miles per hour)." ## Aircraft - Registration: [N9614L](https://openairdocs.org/deregistered/N9614L-2022-01-08), registration cancelled 2022-01-08, S/N 1180, built 1991 (OpenAirDocs) - Reported make and model: AVIAT A-1 - Registry model: [Aviat A-1](https://openairdocs.org/model/aviat-a-1) (registry code 2210302) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1180 - Airframe hours: 52 - Engines: LYCOMING O-360-C1G 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Mills, Richard C. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 20, 1993, 3 hours before - Airport: 0Q4, Selma, runway 28, 2,490 × 50 ft, asphalt ## Flight crew As NTSB recorded them. NTSB leaves out names. - Pilot; age 53; commercial; airplane ratings: single-engine land; instrument ratings: airplane; medical: class 3, valid medical--w/ waivers/lim; seat: left; flight hours: 459 total, 6 in this make and model, 307 as pilot in command, 5 in the last 90 days, 5 in the last 30 days, 5 in the last 24 hours ## Weather - Conditions: Visual (VMC), Day - Wind: 260° at 8 knots - Visibility: 12 statute miles - Lowest ceiling: none - Temperature: 93 °F - Altimeter: 30.00 inHg ## FAA reports on this event (1) The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs). - [Accident 19930720024799A](https://openairdocs.org/incident/19930720024799A), Jul 20, 1993: Chris A1, Carson City, NV, Substantial damage. Veered to left on landing roll. Began go around. Exited runway into rough ground. Pilot reportes reacted incorrectly From the NTSB's public API. 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. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
