# NTSB CHI93LA379: Cessna 150M, N704ZF, Burlington, WI, September 26, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 26, 1993, 13:30 local (18:30 UTC) - Place: Burlington, WI - Coordinates: 42.669429, -88.270362 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.6694&lon=-88.2704&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report July 25, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 9329 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI93LA379 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9329/pdf - Page: https://openairdocs.org/ntsb/CHI93LA379 ## Probable cause the improper fuel calculations by the pilot-in-command. Factors were the pilot-in-command's not refueling and uphill terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, cruise - fluid,fuel - exhaustion - fuel consumption calculations - improper, pilot in command (cause) - refueling - not performed, pilot in command (contributing factor) - Forced landing, descent - emergency - emergency procedure - performed, pilot in command - On ground/water encounter with terrain/water, landing - flare/touchdown - terrain condition - uphill (contributing factor) ## Analysis THE PILOT CALCULATED WHAT HE THOUGHT WOULD BE ADEQUATE FUEL FOR THE PROPOSED FLIGHT. HE DID NOT FUEL THE AIRPLANE PRIOR TO DEPARTURE. AFTER APPROXIMATELY TWO HOURS OF FLIGHT THE AIRPLANE SUSTAINED A TOTAL LOSS OF ENGINE POWER. THE NOSE GEAR IMPACTED UPHILL TERRAIN DURING THE OFF-AIRPORT FORCED LANDING. POST ACCIDENT EXAMINATION OF THE AIRPLANE REVEALED ONLY UNUSABLE FUEL IN TANKS. ## Factual narrative On September 26, 1993, at 1330 central daylight time, a Cessna 150M, N704ZF, registered to Weis Scott of Burlington, Wisconsin, and operated by a private rated pilot, experienced a loss of engine power and a forced landing was conducted into a farm field three miles west of the Burlington, Wisconsin airport. During the forced landing the nose landing gear impacted uphill terrain and the airplane sustained substantial damage. The pilot reported no injuries. The personal 14 CFR Part 91 flight was being conducted in visual meteorological conditions. No flight plan was on file. The local flight departed Burlington, Wisconsin, at approximately 1115. The pilot stated that he departed on the flight from Burlington with what he believed to be 12 gallons of fuel. He indicated that he landed at Kenosha at 1245, taxied back and departed for Burlington where he arrived at 1315. He stated that he then taxied back and decided to make one more take off and landing at Burlington. It was during this last flight that the engine power was lost. In his written statement the pilot stated that he, "Did not have sufficient fuel." Post accident examination of the airplane revealed only unusable fuel on the airplane. A Cessna 150 Owner's Manual excerpt is included as an addendum to this report. It shows "Cruise Performance" with lean mixture fuel consumption rates at 2,500 feet, from a low of 3.2 to a high of 7.0 gallons per hour. ## Aircraft - Registration: [N704ZF](https://openairdocs.org/deregistered/N704ZF-2014-12-15), registration cancelled 2014-12-15, S/N 15078997, built 1976 (OpenAirDocs) - Reported make and model: CESSNA 150M - Registry model: [Cessna 150M](https://openairdocs.org/model/cessna-150m) (registry code 2071830) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15078997 - Engines: CONTINENTAL O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Scott, Weis - Airworthiness certificate: Standard, Normal ## 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. Compare the reported make and model. - [NTSB ATL01LA024](https://openairdocs.org/ntsb/ATL01LA024), Jan 18, 2001: Cessna 152 (N704ZF), St. Augustine, FL, substantial damage. Probable cause: The pilots failure to maintain directional control during the landing roll, which resulted in the collision with the airport sign. 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.
