# NTSB FTW94LA006: Cessna 310I, N8090M, Southlake, TX, October 6, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 5, 1993, 21:30 local (Oct 6, 1993, 02:30 UTC) - Place: Southlake, TX - Coordinates: 32.949665, -97.139831 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.9497&lon=-97.1398&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report August 1, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 18949 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW94LA006 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/18949/pdf - Page: https://openairdocs.org/ntsb/FTW94LA006 ## Probable cause AIRCRAFT CONTROL NOT MAINTAINED BY THE PRIVATE PILOT RECEIVING INSTRUCTION. FACTORS WERE ROUGH RUNWAY, RUNWAY EDGE LIGHTS INOPERATIVE, DARK NIGHT CONDITIONS, BRAKES RESTRICTED DUE TO AN OUT OF RIG RUDDER SYSTEM, AND INADEQUATE CFI SUPERVISION. ## 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 - aircraft control - not maintained, dual student (cause) - supervision - inadequate, pilot in command(cfi) (contributing factor) - airport facilities,runway/landing area condition - rough/uneven (contributing factor) - airport facilities,runway edge lights - inoperative (contributing factor) - light condition - dark night (contributing factor) - flight control,rudder - movement restricted (contributing factor) - On ground/water collision with object, landing - roll - object - airport facility ## Analysis THE PRIVATE PILOT FLYING THE AIRPLANE FROM THE LEFT SEAT WAS RECEIVING DUAL INSTRUCTION FROM A CFI IN THE RIGHT SEAT. TWELVE OUT OF 33 RUNWAY EDGE LIGHTS WERE INOPERATIVE AND IT WAS A DARK NIGHT. AS THE AIRPLANE HIT A BUMP ON THE RUNWAY, IT VEERED TO THE LEFT STRIKING A RUNWAY LIGHT, A POLE, AND A HANGAR. BOTH PILOTS REPORTED APPLYING RIGHT RUDDER AND BRAKES. A MECHANIC'S EXAMINATION OF THE RUDDER AND BRAKES REVEALED THAT WHEN FULL RIGHT RUDDER WAS APPLIED BY THE RIGHT SEAT PILOT, THE RIGHT BRAKE PEDAL CONTACTED THE FIREWALL. THIS PREVENTED FULL RIGHT BRAKE APPLICATION BY EITHER PILOT. ## Factual narrative On October 5, 1993, approximately 2130 central daylight time, a Cessna 310I, N8090M, sustained substantial damage near Southlake, Texas, following a loss of control during the landing roll. The flight instructor, the private pilot receiving instruction, and the passenger were not injured. Visual meteorological conditions prevailed for the local instructional flight. During interviews, conducted by Federal Aviation Administration inspectors, with the private pilot, who was receiving multiengine instruction, and the passenger, the following information was revealed. The airplane hit a bump in the runway and veered to the left side of the runway. The airplane hit a runway landing light and the left wing struck the hangar. The private pilot further stated that both pilots were applying right rudder and right brakes. In the enclosed Pilot/Operator report the flight instructor reported that "it appeared the brakes were not working properly." The private pilot reported, during a personal interview conducted by the investigator-in-charge and on the enclosed Pilot/Operator report, that the airplane landed to the left of the center line of runway 17. He further reported that the airplane "hit a bump on the runway and veered to the left of the runway" and into the grass. As the airplane continued the ground roll, both pilots applied full right rudder and brakes. He stated that "it felt as if the aircraft was skidding and with the full right rudder pedal and left braking, the aircraft kept rolling." He further said that he and the flight instructor did not have right braking with full right rudder. The student said that several runway lights were not working. During several telephone interviews, conducted by the investigator-in-charge, and on the enclosed passenger statement, the passenger/mechanic revealed that the left main wheel struck the runway light, the airplane went completely off the runway and onto the grass which was wet with "heavy dew." The aircraft slid until it hit a pole, subsequently impacted a hangar, and groundlooped as it came to rest. The left wing tip, fuel tank, wing spar, aileron, and right main gear were damaged. Upon examining the braking system, the mechanic stated "when I applied full right rudder and attempted to apply right brakes" the "right brake pedal contacts with the firewall preventing either pilot from braking on the right." A Federal Aviation Administration inspector examination revealed that 12 of 33 runway edge lights were inoperative. The airplane was released to the owner following the investigation. ## Aircraft - Registration: [N8090M](https://openairdocs.org/deregistered/N8090M-2020-08-02), registration cancelled 2020-08-02, S/N 310I0090, built 1964 (OpenAirDocs) - Reported make and model: CESSNA 310I - Registry model: [Cessna 310I](https://openairdocs.org/model/cessna-310i) (registry code 2074224) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310I0090 - Airframe hours: 3614 - Engines: CONTINENTAL IO-470-U 260 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Alam.
