# NTSB CHI94LA281: Beech B-35, N5095C, Boyceville, WI, August 14, 1994 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 14, 1994, 11:10 local (16:10 UTC) - Place: Boyceville, WI - Coordinates: 45.03989, -92.030906 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.0399&lon=-92.0309&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report January 25, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9640 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI94LA281 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9640/pdf - Page: https://openairdocs.org/ntsb/CHI94LA281 ## Probable cause The pilot-in-command's inadequate compensation for the existing wind conditions during the landing flare/touchdown. A factor was the gusty wind conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, landing - flare/touchdown - compensation for wind conditions - inadequate, pilot in command (cause) - weather condition - gusts (contributing factor) - Loss of control - on ground/water, landing - roll - Nose gear collapsed, landing - roll - landing gear,nose gear - overload ## Analysis THE PILOT REPORTED THAT WHILE ON FINAL APPROACH, AT APPROXIMATELY 15 TO 20 FEET ABOVE THE RUNWAY SURFACE, THE AIRPLANE EXPERIENCED AN EXTREME DOWNDRAFT. HE STATED HE FLARED THE AIRPLANE, BUT WAS UNABLE TO KEEP THE AIRPLANE FROM BEING SLAMMED ONTO THE RUNWAY. AFTER THE INITIAL IMPACT, THE AIRPLANE BOUNCED INTO THE AIR IN A NOSE HIGH ATTIUTDE. THE PILOT IMMEDIATELY PUSHED THE NOSE DOWN AND APPLIED ENGINE POWER. THE AIRPLANE IMPACTED THE GRASS ADJACENT TO THE RUNWAY, THE NOSE WHEEL COLLAPSED, AND THE RIGHT WING STRUCK THE GROUND BEFORE THE AIRPLANE CAME TO REST. NO PREIMPACT MECHANICAL ANOMALIES WERE REPORTED BY THE PILOT. THE PILOT REPORTED THE WINDS TO BE FROM 270 DEGREES AT 14 KNOTS, GUSTING TO 20 KNOTS. ## Factual narrative On August 14, 1994, at 1110 central daylight time, a Beech B-35 Bonanza, N5095C, was substantially damaged when it landed hard and skidded off Runway 22 at Boyceville Municipal Airport, Boyceville, Wisconsin. Neither the pilot or the sole passenger aboard were injured. The personal 14 CFR Part 91 flight originated in Strum, Wisconsin, at 1035. The flight operated in visual meteorological conditions without flight plan. In a written statement, the pilot reported everything was normal on final approach to land until approximately 15 to 20 feet above the runway surface. The pilot stated, "...we hit an extreme downdraft. I flared the plane to correct but was unable to stop the plane from being slammed into the runway on its main gear." The pilot stated, after the initial impact the airplane bounced back into the air in an extreme nose high attitude. He immediately pushed the airplane's nose down and increased the engine power. The pilot stated the airplane then impacted the grass adjacent to the runway. The nose wheel collapsed and the right wing struck the ground before the airplane came to rest. No preimpact mechanical anomalies were reported by the pilot. ## Aircraft - Registration: [N5095C](https://openairdocs.org/deregistered/N5095C-2018-02-14), registration cancelled 2018-02-14, S/N D-2357, built 1950 (OpenAirDocs) - Reported make and model: BEECH B-35 - Registry model: [Beech B35](https://openairdocs.org/model/beech-b35) (registry code 1151506) (OpenAirDocs) - Registry engine: [Continental E185 series](https://openairdocs.org/engine/continental-e185-series) (registry code 17014, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: D-2357 - Airframe hours: 8050 - Engines: CONTINENTAL E-185-8 196 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Joel D.

Lost control landing in gusty wind. Wing struck runway. Slid off runway. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
