# NTSB LAX89LA177: Cessna 310C, N1798H, Jackson, CA, May 3, 1989 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 3, 1989, 11:00 local (18:00 UTC) - Place: Jackson, CA - Coordinates: 38.349849, -120.769569 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=38.3498&lon=-120.7696&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 24, 1990 - Report: Approved by Office Director - NTSB case key (mKey): 26396 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX89LA177 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/26396/pdf - Page: https://openairdocs.org/ntsb/LAX89LA177 ## Probable cause THE FAILURE OF THE INSTRUCTOR PILOT (PILOT IN COMMAND) TO REJECT THE TAKEOFF AFTER THE LOSS OF POWER ON ONE ENGINE WHEN SUFFICIENT RUNWAY REMAINED TO STOP THE AIRCRAFT. CONTRIBUTING TO THE ACCIDENT WAS THE DISREGARD OF THE AIRCRAFT MANUAL, FAILURE TO USE THE FUEL BOOST PUMP AND EXCEEDING THE AIRCRAFT SINGLE ENGINE PERFORMANCE CAPABILITY. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, takeoff - roll/run - 1 engine - failure,total - fuel boost pump selector position - not selected, pilot in command(cfi) (contributing factor) - flight manuals - disregarded, pilot in command(cfi) (contributing factor) - aborted takeoff - not performed, pilot in command(cfi) (cause) - Loss of control - in flight, takeoff - initial climb - aircraft performance,engine out capability - exceeded (contributing factor) - Forced landing, descent - emergency - terrain condition - none suitable - On ground/water collision with object, landing - roll - object - pole ## Analysis THE ACFT OWNER WAS TAKING MEL TRAINING FOR A CLASS RATING. HE STATED THAT THE CFI TOLD HIM TO NOT USE THE AUX ELECTRIC FUEL PUMPS DURING TAKEOFF, A PROCEDURE IN CONTRADICTION TO THE FLIGHT MANUAL. DURING THE TAKEOFF GROUND ROLL, THE STUDENT SAID THE RIGHT ENGINE QUIT AT A SPEED JUST BELOW ROTATION. THE CFI ASSUMED CONTROL OF THE ACFT AND CONTINUED THE TAKEOFF, LOST CONTROL OF THE ACFT AND LANDED IN A FIELD OFF THE DEPARTURE END OF THE RUNWAY. THE STUDENT SAID THE ACFT WAS HALFWAY DOWN THE 3,400 FT RUNWAY WHEN THE ENGINE QUIT. THE FLIGHT MANUAL LISTS VMC AS 82 MPH, AND, VYSE AS 109 MPH. THE TAKEOFF AND LANDING GROUND ROLL DISTANCE CHARTS IN THE FLIGHT MANUAL STATE THAT 960 FEET IS REQUIRED TO ACCELERATE TO 86 MPH, AND 650 FT IS REQUIRED TO DECELERATE FROM THAT SPEED. EXAM OF THE ACFT REVEALED THAT THE RIGHT PROPELLER WAS NOT FEATHERED, AND NO REASON WAS FOUND FOR THE RIGHT ENGINE POWER LOSS. ## Aircraft - Registration: [N1798H](https://openairdocs.org/deregistered/N1798H-2012-08-13), registration cancelled 2012-08-13, S/N 35898, built 1959 (OpenAirDocs) - Reported make and model: CESSNA 310C - Registry model: [Cessna 310C](https://openairdocs.org/model/cessna-310c) (registry code 2074210) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 35898 - Airframe hours: 3381 - Engines: CONTINENTAL IO-470-D 260 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Mason, Richard I. - Registered owner: Richard I Mason - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 1, 1989, 12 hours before - Departed: O70, JACKSON, CA - Destination: O70 - Airport: 070, Westover, runway 10, 3,400 × 60 ft, asphalt ## Flight crew As NTSB recorded them.
