# NTSB LAX03LA019: Bell 47G-2, N2616B, Pollock Pines, CA, November 2, 2002 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: November 2, 2002, 09:10 local (17:10 UTC) - Place: Pollock Pines, CA - Coordinates: 38.722778, -120.601669 - Nearby events: https://openairdocs.org/map.md?lat=38.7228&lon=-120.6017&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 2 uninjured - Status: Completed, report October 28, 2004 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 56014 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX03LA019 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/56014/pdf - Page: https://openairdocs.org/ntsb/LAX03LA019 ## Probable cause The pilot's failure to maintain adequate obstruction clearance during initial climb, which resulted in a collision with vegetation. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, takeoff - terrain condition - high vegetation - altitude/clearance - inadequate, pilot in command (cause) - Roll over, takeoff ## Analysis During initial climb from a 3,500-foot mean sea level plateau, the helicopter's skid collided with a 3-foot-high bush. The helicopter yawed and impacted the ground. The pilot reported that the collision occurred after he had increased the helicopter's collective pitch and accelerated to about 20 knots, thereby starting to acquire effective translational lift. ## Factual narrative On November 2, 2002, about 0910 Pacific standard time, a Bell 47G-2, N2616B, collided with a bush and terrain during an attempted takeoff from a plateau near Pollock Pines, California. The helicopter was substantially damaged. The commercial pilot and one passenger were not injured. The second passenger received a minor injury. Visual meteorological conditions prevailed, and no flight plan was filed. The helicopter was operated for hire on a photography flight under the provisions of 14 CFR Part 91, by D. C. Rotor & Wing, Rancho Murieta, California. The flight originated from Rancho Murieta about 0810. The pilot reported to the National Transportation Safety Board investigator that he flew to the plateau and landed. The two passengers exited the helicopter to take pictures. The helicopter's engine was kept running. Thereafter, the passengers reboarded the helicopter to continue their flight. The pilot stated that because of the ambient conditions, including the 3,500-foot mean sea level elevation and estimated 40-degree Fahrenheit temperature, the helicopter did not have adequate power to make a normal departure from a hover. However, the pilot indicated that he believed there was sufficient clear area over the rocky terrain to perform a running takeoff. According to the pilot, during the accident sequence he increased the helicopter's collective pitch and accelerated to about 20 knots thereby starting to acquire effective translational lift. During this initial climb a skid collided with a 3-foot-tall bush. The helicopter suddenly yawed and impacted the ground. In the pilot's completed "Aircraft Accident Report" he stated that "...the purpose of the flight was to encourage [one of the passengers] to resume her flight training with D.C. Rotor." ## Aircraft - Registration: [N2616B](https://openairdocs.org/deregistered/N2616B-2013-08-21), registration cancelled 2013-08-21, S/N 2475 (OpenAirDocs) - Reported make and model: Bell 47G-2 - Registry model: [Bell-Yehnert 47G-2](https://openairdocs.org/model/bell-yehnert-47g-2) (registry code 1181310) (OpenAirDocs) - Category: Helicopter - Serial number: 2475 - Airframe hours: 7232 - Engines: Lycoming VO-435-A1F 260 horsepower reciprocating - Damage: Substantial damage - Flight: Other work use, Part 91 - Operator: D.

(-23) During take off helicopter struck bush and crashed. 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.
