# NTSB CEN23LA080: Beech G33, N9283Q, Bolingbrook, IL, January 10, 2023 - Type: NTSB accident investigation - Classification: Accident · No injuries · Class 4 · Limited · Final report - Date: January 10, 2023, 13:58, time zone not recorded - Place: Bolingbrook, IL - Coordinates: 41.728044, -88.034925 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=41.7280&lon=-88.0349&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Defining event: [Approach: Fuel starvation](https://openairdocs.org/ntsb-events/191) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed - Report: Approved by Office Director - Investigation class: Class 4 - Basic report with no Prelim publish - NTSB office: Central Region - Parties: FAA FSDO - NTSB case key (mKey): 106582 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CEN23LA080 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/106582/pdf - NTSB docket: https://data.ntsb.gov/Docket?ProjectID=106582 - Page: https://openairdocs.org/ntsb/CEN23LA080 ## Probable cause The pilot's inadequate fuel management, which resulted in a total loss of engine power due to fuel starvation. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Use of equip/info: use of equip/system](https://openairdocs.org/ntsb-findings/02063015): Personnel issues › Task performance · Pilot (probable cause) - [Fluids: fuel](https://openairdocs.org/ntsb-findings/01071010): Aircraft › Fluids/misc hardware · Fluid management (probable cause) ## Analysis The pilot reported the engine lost total power while he was on approach to his destination airport. According to the pilot, he attempted to restart the engine by switching fuel tanks, but he may have forgotten to engage the boost pump, and the restart was unsuccessful. The pilot then conducted a forced landing on a freeway, during which the right and left wings sustained substantial damage. Postaccident examination of the airplane revealed that the left fuel tank contained no usable fuel, the right fuel tank had visible but unknown quantity of fuel. After the airplane was recovered from the freeway, a functional engine test run, with the right fuel tank selected, was completed with no anomalies noted. After the accident, the pilot stated that he should have incorporated better fuel management techniques. The loss of engine power was attributed to fuel starvation. ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Approach: Fuel starvation](https://openairdocs.org/ntsb-events/191) (defining event) - [Approach: Loss of engine power (total)](https://openairdocs.org/ntsb-events/341) - [Landing-flare/touchdown: Off-field or emergency landing](https://openairdocs.org/ntsb-events/440) ## Aircraft - Registration: [N9283Q](https://openairdocs.org/aircraft/N9283Q), registered now, S/N CD-1259, built 1971 (OpenAirDocs) - Reported make and model: BEECH G33 - Registry model: [Beech G33](https://openairdocs.org/model/beech-g33) (registry code 1151435) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CD-1259 - Year built: 1971 - Airframe hours: 3500 - Engines: Continental IO-470-N 260 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Utility - Last inspection: Annual, September 1, 2022 - Departed: C29, Middleton, WI - Destination: LL22, Downers Grove, IL - Flight plan: IFR - Equipment: Auto-pilot, ADS-B ## Flight crew As NTSB recorded them.
