# NTSB DEN03LA097: Bell 206B III, N382SP, Broomfield, CO, May 31, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 31, 2003, 14:30 local (20:30 UTC) - Place: Broomfield, CO - Coordinates: 39.94049, -105.060798 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.9405&lon=-105.0608&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 25, 2003 - Report: Approved by Office Director - Parties: FAA FSDO - NTSB case key (mKey): 57140 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN03LA097 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/57140/pdf - Page: https://openairdocs.org/ntsb/DEN03LA097 ## Probable cause the student pilot's failure to maintain aircraft control and the instructor's inadequate supervision. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Dragged wing,rotor,pod,float or tail/skid, landing - flare/touchdown - loss of tail rotor effectiveness - simulated, pilot in command - aircraft control - not maintained, pilot in command (cause) - supervision - inadequate, pilot in command(cfi) (contributing factor) - Hard landing, landing - flare/touchdown - terrain condition - runway ## Analysis According to the instructor, he demonstrated six (three left and three right), stuck pedal approaches [simulated loss of tail rotor effectiveness]. The student took the controls and set up for a simulated stuck right pedal approach. As the student added collective lever control at the end of the approach, the nose of the helicopter yawed to the right. Approximately 2 feet above the taxiway, the student rolled off the power to control the right yaw. The helicopter settled down in a tail low attitude, the rear of both landing skids struck the taxiway, and the helicopter rocked forward. When the instructor took the controls to stabilize the landing, the helicopter became airborne and the right skid tube struck the taxiway a second time. He rolled the helicopter forward, landed on both skid tubes, and slid the helicopter to a stop. The helicopter received substantial damage to both aft cross-tube saddle mounts. ## Factual narrative On May 31, 2003 at 1430 mountain daylight time, a Bell 206B III helicopter, N382SP, was substantially damaged during a hard landing at Jeffco Airport (BJC), Broomfield, Colorado. The commercial certificated flight instructor and the private pilot receiving instruction were not injured. Visual meteorological conditions prevailed. No flight plan had been filed for this local instructional flight being conducted under Title 14 CFR Part 91. The flight originated at approximately 1345. According to the instructor, he demonstrated six (three left and three right), stuck pedal approaches [simulated loss of tail rotor effectiveness]. The student took the controls and set up for a simulated stuck right pedal approach to taxiway Delta. As the student added collective lever control at the end of the approach, the nose of the helicopter yawed to the right. Approximately 2 feet above the taxiway, the student rolled off the power to control the right yaw. The helicopter settled down in a tail low attitude, the rear of both landing skids struck the taxiway, and the helicopter rocked forward. When the instructor took the controls to stabilize the landing, the helicopter became airborne and the right skid tube struck the taxiway a second time. He rolled the helicopter forward, landed on both skid tubes, and slid the helicopter to a stop. The helicopter received substantial damage to both aft cross-tube saddle mounts. ## Aircraft - Registration: [N382SP](https://openairdocs.org/aircraft/N382SP), registered now, S/N 2271, built 1977 (OpenAirDocs) - Reported make and model: Bell 206B III - Registry model: [Bell 206B](https://openairdocs.org/model/bell-206b) (registry code 1181511) (OpenAirDocs) - Registry engine: [Rolls-Royce 250-C20B](https://openairdocs.org/engine/rolls-royce-250-c20b) (registry code 54385, turbo-shaft) (OpenAirDocs) - Category: Helicopter - Serial number: 2271 - Airframe hours: 8021.3 - Engines: Allison 250 C20S 420 horsepower turbo shaft - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Bill Murphy & Tim Kosmerl - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 1, 2003, 58.9 hours before - Departed: BJC - Destination: BJC, CO - Airport: BJC, Jeffco ## Flight crew As NTSB recorded them.
