# NTSB CHI94LA326: Cessna 172, N7384G, Brookfield, WI, September 8, 1994 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: September 8, 1994, 08:45 local (13:45 UTC) - Place: Brookfield, WI - Coordinates: 43.07994, -88.249725 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.0799&lon=-88.2497&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 2 uninjured - Status: Completed, report January 12, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9681 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI94LA326 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9681/pdf - Page: https://openairdocs.org/ntsb/CHI94LA326 ## Probable cause the commercial pilot's poor planning/decision making. A related factor is the wet, grass runway selected for landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - terrain condition - grass (contributing factor) - terrain condition - wet (contributing factor) - planning/decision - poor, pilot in command (cause) - Nose gear collapsed, landing - landing gear,nose gear - overload ## Analysis THE PILOT STATED THE AIRPLANE TOUCHED DOWN APPROXIMATELY 1/4 TO 1/3 DOWN A 1,250 FOOT LONG GRASS STRIP. HE APPLIED BRAKES, BUT THE AIRPLANE CONTINUED OFF THE DEPARTURE END OF THE RUNWAY. THE PILOT REPORTED THE WINDS WERE CALM AND THERE WAS DEW ON THE GRASS. HE STATED THERE WAS NO MECHANICAL MALFUNCTION. THERE WERE TWO OTHER RUNWAYS AVAILABLE AT THE AIRPORT, RWY 03/21 (3,500' X 40', ASPHALT) AND RWY 09/27 (3,250' X 100', TURF). ## Factual narrative On September 8, 1994, at 0845 central daylight time, a Cessna 172, N7384G, operated for the purpose of aerial traffic observation, sustained substantial damage when it ran off the departure end of Runway 36 at Capitol Airport in Brookfield, Wisconsin. The commercial pilot and one of the two passengers on board the airplane reported no injuries. The other passenger reported minor injuries. Visual meteorological conditions prevailed for the local flight, no flight plan was filed. The flight operated under 14 CFR Part 91, and originated from Brookfield, Wisconsin approximately 0545. The pilot stated the airplane touched down "...approximately 1/4 to 1/3 down the runway. The amount of runway left was still adequate to safely stop. I began to apply the brakes, but they did not perform effectively enough to stop safely." The pilot stated he considered aborting the landing, but he believed the airplane would not clear the trees located at the end of the runway. He reported he kept the airplane on the ground to minimize damage and injuries, and slowed the airplane as much as possible. The airplane continued off the departure end of the runway and came to rest in a swampy area. The pilot stated winds were calm and there was dew on the 1,250' grass runway. Two other runways were available at the Capitol Airport: Runway 09/27 (3,270' X 100', turf) and Runway 03/21 (3,500' X 40', asphalt). The pilot's recommendation as to how the accident could have been prevented was: "Reduce power earlier, flare a little bit sooner and less flaps." He stated there was no mechanical malfunction/failure. ## Aircraft - Registration: [N7384G](https://openairdocs.org/deregistered/N7384G-2017-07-12), registration cancelled 2017-07-12, S/N 17259084, built 1970 (OpenAirDocs) - Reported make and model: CESSNA 172 - Registry model: [Cessna 172K](https://openairdocs.org/model/cessna-172k) (registry code 2072430) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17270337 - Engines: LYCOMING O-320-H2AD 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Eagle Aviation, Inc. - Registered owner: Eagle Aviation, Inc. - Airworthiness certificate: Standard, Normal - Departed: 02C - Destination: 02C - Airport: 02C, Capitol, runway 36, 1,250 × 90 ft, grass/turf ## 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.
