# NTSB CHI05CA131: Cessna TU206G, N95AK, West Bloomfield, MI, May 30, 2005 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Data collection · Final report - Date: May 30, 2005, 13:05 local (17:05 UTC) - Place: West Bloomfield, MI - Coordinates: 42.599998, -83.449996 - Nearby events: https://openairdocs.org/map.md?lat=42.6000&lon=-83.4500&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report September 13, 2005 - Report: Approved by Office Director - Parties: FAA-Detroit FSDO - NTSB case key (mKey): 61646 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI05CA131 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/61646/pdf - Page: https://openairdocs.org/ntsb/CHI05CA131 ## Probable cause The pilot's inadvertent water landing with the amphibious-float wheels extended causing the airplane to nose over. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - wheels down landing in water - inadvertent, pilot in command (cause) - terrain condition - water - Nose over, landing ## Analysis The amphibious-float equipped airplane was substantially damaged when the pilot attempted to land on a lake with the wheels extended. The airplane subsequently nosed over. The pilot reported that he departed a land-based airport and flew in the local area for approximately 30 minutes. He recalled raising the wheels after takeoff. The pilot stated that prior to returning to the departure airport for landing he decided to make a "quick splash [and] dash" at a lake. The pilot reported that he set-up for a touch and go landing on the water. He recalled the landing gear control lever and the gear position indictor lights were proper for a wheels-up (water) landing. He reportedly touched down at 40 miles-per-hour (mph) and the airplane "started to dig into the waves." Approximately 30 mph the airplane nosed over into the water. The pilot recalled seeing the wheels in the extended position and hearing the hydraulic motor running as he exited the aircraft after the accident. The landing gear and instrument indicator lights operated normally during a post-accident inspection. ## Factual narrative On May 30, 2005, at 1305 eastern daylight time, a Cessna TU206G airplane on amphibious floats, N95AK, piloted by a private pilot, was substantially damaged when it nose over during landing on Union Lake near West Bloomfield, Michigan. The personal flight was being conducted under 14 CFR Part 91 without a flight plan. Visual meteorological conditions prevailed. The pilot sustained minor injuries. In his written statement, the pilot reported that he departed Oakland County International Airport (PTK), Pontiac, Michigan, and flew in the local area for approximately 30 minutes. He recalled raising the wheels after takeoff. The pilot stated that prior to returning to PTK for landing he decided to make a "quick splash [and] dash" at Union Lake. The pilot reported that he set-up for a touch and go landing on the water. He recalled the landing gear control lever and the gear position indictor lights were proper for a wheels-up (water) landing. He reportedly touched down at 40 miles-per-hour (mph) and the airplane "started to dig into the waves." Approximately 30 mph the airplane nosed over into the water. The pilot recalled seeing the wheels in the extended position and hearing the hydraulic motor running as he exited the aircraft after the accident. A post-accident inspection was conducted. The airplane was supported on jacks and the landing gear was operated via the selector handle in the cockpit. The landing gear retracted and extended normally during that time. In addition, the indicator lights on the instrument panel functioned properly. ## Aircraft - Registration: N95AK (not matched to a registry record) - Reported make and model: Cessna TU206G - Category: Airplane - Serial number: U20606539 - Airframe hours: 2000 - Engines: Continental TSIO-520 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Komer Lake Air Development LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 1, 2005, 20 hours before - Departed: PTK, Pontiac, MI - Airport: PTK, Oakland-Pontiac ## 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.
