# NTSB SEA04CA164: Cessna U206G, N9752Z, Rose Lake, ID, August 13, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: August 13, 2004, 13:20 local (20:20 UTC) - Place: Rose Lake, ID - Coordinates: 47.530277, -116.565277 - Nearby events: https://openairdocs.org/map.md?lat=47.5303&lon=-116.5653&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report October 28, 2004 - Report: Approved by Office Director - NTSB case key (mKey): 59929 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA04CA164 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/59929/pdf - Page: https://openairdocs.org/ntsb/SEA04CA164 ## Probable cause The pilot's failure to maintain clearance with the powerlines on final approach which resulted in a hard landing. A factor contributing the to accident were the powerlines. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, approach - vfr pattern - final approach - clearance - not maintained, pilot in command (cause) - object - wire,transmission (contributing factor) - Hard landing, descent ## Analysis The pilot was approximately 50 feet above the water approaching the lake preparing to land when he saw the wires. In an effort to clear the wires, the pilot immediately added full power and back pressure on the yoke. The wires subsequently went over the top of the floats and caught onto both float struts, eventually breaking free from the right side but remaining entangled on the left float strut and pulling the airplane down. The pilot then pulled the nose up just prior to impacting the water, resulting in substantial damage to the airplane. ## Factual narrative On August 13, 2004, about 1320 Pacific daylight time, a Cessna U206G, N9752Z, sustained substantial damage after striking powerlines while on final approach to Killkarney Lake, located approximately 5 nautical miles southwest of Rose Lake, Idaho. The airplane was registered to and operated by Brooks Seaplane Services, Inc., of Coeur d'Alene, Idaho. The commercial pilot and his two passengers were not injured. Visual meteorological conditions prevailed for the on-demand charter flight, which was operated under the provisions of Title 14, CFR Part 135, when the accident occurred, and a flight plan was not filed. The flight originated from Coeur d'Alene, Idaho, approximately 20 minutes prior to the accident. In a written statement, the pilot reported that prior to the approach and landing he flew over the area at approximately 500 feet above ground level (AGL) to determine the direction of the wind and to look for logs and debris in the lake. The pilot stated that he was approaching the north end of the lake on a southerly heading and near the lake's edge at approximately 50 feet AGL when he saw the wires. The pilot reported that he immediately added full power to raise the nose when the top wire went over the top of the floats, catching the float struts. The pilot stated that the wire broke off the right side but was still entangled on the left side, pulling the airplane down. The pilot reported that he then pulled the nose up before impacting the water. Damage to the aircraft included the left hand front door frame post being cracked, the upper top cabin skin wrinkled, and the left hand cabin bulkhead bent. ## Aircraft - Registration: [N9752Z](https://openairdocs.org/aircraft/N9752Z), registered now, S/N U20606644, built 1982 (OpenAirDocs) - Reported make and model: Cessna U206G - Registry model: [Cessna U206G](https://openairdocs.org/model/cessna-u206g) (registry code 2073356) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20606644 - Engines: Continental IO-550 reciprocating - Damage: Substantial damage - Flight: Part 135 - Operator: Brooks Seaplane Service Inc. - Registered owner: Brooks Seaplane Service Inc. - Airworthiness certificate: Standard, Normal - Departed: S76, Coeur d'Lane, ID - Destination: Rose Lake, ID ## 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.
