# NTSB CHI00LA136: Beech A23-19, N5665S, Holmen, WI, May 14, 2000 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: May 14, 2000, 12:00 local (17:00 UTC) - Place: Holmen, WI - Coordinates: 43.950263, -91.250785 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.9503&lon=-91.2508&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious, 1 uninjured - Status: Completed, report May 22, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49180 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI00LA136 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49180/pdf - Page: https://openairdocs.org/ntsb/CHI00LA136 ## Probable cause the pilot's failure to maintain directional control of the airplane during the landing. Factors associated with the accident were the crosswind, along with the runway light, windsock, garden, and swimming pool that the airplane contacted. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - weather condition - crosswind (contributing factor) - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, landing - object - runway light (contributing factor) - object - pole (contributing factor) - terrain condition - high vegetation (contributing factor) - object - other (contributing factor) ## Analysis The pilot performed a go-around due to the crosswind condition during his first landing. He reported a gust of wind lifted the airplane during the second landing which resulted in the airplane traveling off the right side of the runway. The airplane contacted a runway light, a wind sock, a garden, and shrubs. The right wing then contacted a maple tree which yawed the airplane to the right and it came to rest in a swimming pool. The inspector reported the residence where the swimming pool was located was approximately 150 to 200 feet from the runway. Wind reported at LaCrosse, Wisconsin, 11 miles south of the accident site, at 1150 cdt, were from 300 degrees at 15 knots. ## Factual narrative On May 14, 2000, at 1200 central daylight time (cdt), a Beech A23-19, N5665S, collided with the terrain and a swimming pool, following a loss of directional control while landing on runway 36 (3,200' x 60', asphalt) at the Holland Airpark, Holmen, Wisconsin. The private pilot was not injured and the passenger suffered serious injuries. The 14 CFR Part 91 flight was operating in visual meteorological conditions without a flight plan. The flight originated from Reedsburg, Wisconsin, at 1100 cdt. The pilot reported he made a landing attempt with a crosswind from the west-northwest. He reported he "Didn't like [the] attempt" and he elected to perform a go-around. The pilot reported that a gust of wind from the west-northwest was encountered after touching down on the second landing. He reported he was approximately half way down the runway when this occurred. The pilot reported the gust lifted the airplane and moved it to the right of the runway. He reported he "Could not get plane back to runway and ended up in an above ground swimming pool." The accident site was examined by an inspector from the Federal Aviation Administration Milwaukee Flight Standards District Office. The inspector reported the airplane traveled off the right side of the runway where it contacted a runway light, a wind sock, a garden, and shrubs. The right wing of the airplane then contacted a maple tree which yawed the airplane to the right prior to it coming to rest in the swimming pool. The inspector reported the residence where the swimming pool was located was approximately 150 to 200 feet from the runway. Wind reported at LaCrosse, Wisconsin, 11 miles south of the accident site, at 1150 cdt, were from 300 degrees at 15 knots. ## Aircraft - Registration: [N5665S](https://openairdocs.org/deregistered/N5665S-2000-10-20), registration cancelled 2000-10-20, S/N MB-102 (OpenAirDocs) - Reported make and model: Beech A23-19 - Registry model: [Beech A23-19](https://openairdocs.org/model/beech-a23-19) (registry code 1151212) (OpenAirDocs) - Category: Airplane - Serial number: MB-102 - Airframe hours: 4956 - Engines: Lycoming O-320-E2C 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Everett M.

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.
