# NTSB SEA07TA214: Bell 214ST, N724HT, McCall, ID, July 26, 2007 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Final report - Date: July 25, 2007, 19:47 local (Jul 26, 2007, 01:47 UTC) - Place: McCall, ID - Coordinates: 45.174999, -115.721107 - Nearby events: https://openairdocs.org/map.md?lat=45.1750&lon=-115.7211&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious, 1 minor - Status: Completed, report March 31, 2008 - Report: Approved by Office Director - Parties: United Stated Department of Agriculture, Federal Aviation Administration - NTSB case key (mKey): 66303 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA07TA214 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66303/pdf - Page: https://openairdocs.org/ntsb/SEA07TA214 ## Probable cause The pilot's inadequate planned approach that led to settling with power. Contributing to the accident was the external load becoming snagged in the water, and the high density altitude. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, maneuvering - planned approach - inadequate, pilot in command (cause) - weather condition - high density altitude (contributing factor) - settling with power - encountered, pilot in command (cause) - towing/advertising/external load equipment - snagged (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - muddy ## Analysis The pilot reported that he encountered the onset of settling with power while approaching a lake to fill an external bucket attached to a 150-foot long-line. He lowered the collective, and initiated a 180-degree turn. During the turn, the bucket entered the water, and the long-line pulled the helicopter from the right side while the pilot was maneuvering. Subsequently, the helicopter collided with terrain adjacent to the shoreline of the lake resulting in substantial damage. The operator reported the estimated density altitude at the time of the accident was 10,221 feet, and the winds were light and variable. Examination of the helicopter revealed no mechanical anomalies with the engine or airframe. ## Factual narrative On July 25, 2007, at 1947 mountain daylight time, a Bell 214ST helicopter, N724HT, sustained substantial damage when it impacted terrain following a loss of control while conducting long-line operations in a remote area 22 miles northeast of McCall, Idaho. The airline transport pilot (ATP) sustained serious injuries and the passenger/crew chief, sustained minor injuries. The helicopter was registered to US Leaseco, Inc of Baltimore, Maryland, and under the operational control of the United States Forest Service (USFS). Visual meteorological conditions prevailed and a flight plan was filed for the local public use flight. The purpose of the flight was to conduct external load operations in support of the Loon fire. In a written statement provided by USFS personnel, the pilot was making an approach to a lake in order to fill a 900-gallon Bambi bucket attached to a 150-foot long-line. As the approach continued, and just prior to the bucket entering the water, the pilot reported that "he was encountering the onset of settling with power." The pilot lowered the collective and initiated a 180-degree turn. During the turn, the bucket entered the water and the 150-foot long-line "pulled the helicopter" on "the right side of the aircraft" while the pilot was maneuvering about 20-40 feet above the water. Subsequently, the helicopter collided with terrain in a marshy area adjacent to the shoreline resulting in substantial damage. The operator reported the estimated density altitude at the time of the accident was 10,221 feet. Examination of the helicopter revealed no mechanical anomalies with the engine or airframe. ## Aircraft - Registration: [N724HT](https://openairdocs.org/deregistered/N724HT-2018-04-18), registration cancelled 2018-04-18, S/N 28123, built 1983 (OpenAirDocs) - Reported make and model: Bell 214ST - Registry model: [Bell 214ST](https://openairdocs.org/model/bell-214st) (registry code 1182106) (OpenAirDocs) - Registry engine: [GE CT7 series](https://openairdocs.org/engine/ge-ct7-series) (registry code 30030, turbo-shaft) (OpenAirDocs) - Category: Helicopter - Serial number: 21823 - Airframe hours: 2518 - Engines: General Electric CT7-2A 1625 horsepower turbo shaft - Damage: Substantial damage - Flight: Public aircraft, Public use - Operator: US Forest Service - Registered owner: US LEASECO Inc. - Airworthiness certificate: Standard, Transport - Last inspection: Continuous airworthiness, July 1, 2007, 45 hours before - Departed: McCall, ID - Destination: McCall, ID - Flight plan: Company VFR ## 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.
