# NTSB CHI98LA261: Cessna 182A, N2139G, Springbrook, WI, July 17, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 17, 1998, 12:45 local (17:45 UTC) - Place: Springbrook, WI - Coordinates: 45.939746, -91.680862 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.9397&lon=-91.6809&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report May 19, 1999 - Report: Approved by Office Director - NTSB case key (mKey): 43091 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI98LA261 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43091/pdf - Page: https://openairdocs.org/ntsb/CHI98LA261 ## Probable cause The pilot's improper attitude and excessive sink rate during landing. The terrain condition was a contributing factor in the accident. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - proper descent rate - excessive, pilot in command (cause) - flare - inadequate, pilot in command (cause) - terrain condition - high vegetation (contributing factor) - Nose gear collapsed, landing - flare/touchdown - flare - inadequate, pilot in command (cause) - landing gear,nose gear - overload (cause) - Nose over, landing - roll - landing gear,nose gear - missing (cause) ## Analysis The pilot stated that he had flown a normal short field pattern with a final approach configuration at 300' agl of 40 degrees of flap and an airspeed of 60 KIAS. The aircraft touched down firmly in a three point attitude and bounced. Upon the second touch down, the aircraft rolled for approximately 200' - 400' at which point the nose came down without the nose wheel. The nose wheel strut dug into the ground and the aircraft nosed over. Examination of the airstrip by a Federal Aviation Inspector revealed the field conditions to be dry and the height of vegetation to be approximately 2' - 3'. The ground scar from the nose wheel was observed to be more pronounced than that produced by the main wheels. The nose wheel was located 156' left of the initial touchdown point at a relative bearing of 035 degrees. The fractured nose wheel U-bracket exhibited no evidence of fatigue or preexisting crack. ## Factual narrative On July 17, 1998, at 1245 central daylight time, a Cessna 182A, N2139G, operated by a commercial pilot, received substantial damage during landing at a private airstrip (2400' x 300', grass) near Springbrook, Wisconsin. The pilot was attempting a short field landing when the aircraft bounced and subsequently nosed over. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 personal flight was not operating on a flight plan. The pilot and passenger received no injuries. The local flight departed from Hayward, Wisconsin at 1145 In a written statement, the pilot stated that he had flown a normal short field pattern with a final approach configuration at 300' agl of 40 degrees of flaps and an airspeed of 60 KIAS. The aircraft touched down firmly in a three point attitude and bounced. The pilot touched down a second time with a full aft application of the control yoke. The aircraft rolled for approximately 200' - 400' at which point the nose came down without the nose wheel. The nose wheel strut dug into the ground and the aircraft nosed over. The pilot stated that the nose wheel yoke failed on landing due to possible metal fatigue. Examination of the airstrip by a Federal Aviation Inspector revealed the field conditions to be dry and the height of vegetation to be approximately 2' - 3'. The ground scar from the nose wheel was observed to be more pronounced than that produced by the main landing gear wheels. The nose wheel was located 156' left of the initial touchdown point at a relative bearing of 035 degrees. The fractured nose wheel U-bracket exhibited no evidence of fatigue or preexisting crack. ## Aircraft - Registration: [N2139G](https://openairdocs.org/aircraft/N2139G), registered now, S/N 51439, built 1958 (OpenAirDocs) - Reported make and model: Cessna 182A - Registry model: [Cessna 182A](https://openairdocs.org/model/cessna-182a) (registry code 2072704) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 51439 - Airframe hours: 3708 - Engines: Continental 0470 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Donald Pfister - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 19, 1998, 51 hours before - Departed: HYR, HAYWARD, WI - Airport: Springbrook, runway 27, 2,400 × 300 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.
