# NTSB NYC95LA101: Bell 206B, N219CT, Hamilton, MA, May 4, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 3, 1995, 21:30 local (May 4, 1995, 01:30 UTC) - Place: Hamilton, MA - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 8, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 38955 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC95LA101 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38955/pdf - Page: https://openairdocs.org/ntsb/NYC95LA101 ## Probable cause the pilot's improper decision to fly at night with a night vision deficiency, and his failure to maintain clearance with trees during takeoff, which resulted in an in-flight collision with the trees and the subsequent hard landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, takeoff - initial climb - light condition - dark night - object - tree(s) - altitude/clearance - not maintained, pilot in command (cause) - judgment - improper, pilot in command (cause) - physical impairment(visual deficiency), pilot in command - Forced landing, descent - emergency - Hard landing, descent - emergency ## Analysis THE PILOT ATTEMPTED A TAKEOFF FROM A TREE SURROUNDED FIELD AT NIGHT, IN HIS PERSONALLY OWNED HELICOPTER. DURING INITIAL CLIMB, THE MAIN ROTOR BLADES STRUCK TREES AND THE PILOT INITIATED A FORCED LANDING. THE HELICOPTER LANDED HARD AND ROLLED OVER ON ITS SIDE. THE PRIVATE PILOT HAD ACCUMULATED ABOUT 60 HOURS IN THIS MAKE AND MODEL, WITH 40 HOURS AS PILOT-IN-COMMAND. THE PILOT'S LAST THIRD CLASS MEDICAL WAS ISSUED 3 YEARS PRIOR TO THE ACCIDENT WITH THE RESTRICTIONS, 'NOT VALID FOR NIGHT FLYING OR BY COLOR SIGNAL CONTROL.' ## Factual narrative On May 3, 1995, at 2130 eastern daylight time, a Bell 206B, N219CT, was substantially damaged when it struck trees and impacted the ground during a night takeoff near Hamilton, Massachusetts. The private pilot was not injured. Visual meteorological conditions prevailed for the personal flight. No flight plan had been filed for the flight conducted under 14 CFR Part 91. In the NTSB Form 6120.1/2, the pilot stated that at 2130, after engine start and run-up, he brought his personally owned helicopter to hover. He further stated: ...I checked controllability, C.G., and began a max- performance takeoff; at approximately 30 feet AGL the main rotor made contact with a large branch from an adjacent oak tree. I lowered the collective immediately and applied right pedal (autorotation), and attempted to make a running landing in an open grassy area. At approximately 8 feet I flared, bringing the speed back to 5 to 8 knots; the helicopter made contact with the ground in a slight right yaw. The helicopter slowly tilted right and entered dynamic rollover. The main rotors made contact with the ground and threw the aircraft onto it's left side. According to a Federal Aviation Administration (FAA) Inspector, the helicopter had been parked in a field about 200 feet long and 150 feet wide, surrounded by trees 75 feet high. The pilot had accumulated about 60 hours in this make and model helicopter, with 40 hours as a pilot-in-command. The pilot's last third class medical was issued May 9, 1992, with the restriction, "not valid for night flying or by color signal control." ## Aircraft - Registration: N219CT (not matched to a registry record) - Reported make and model: BELL 206B - Category: Helicopter - Serial number: 2298 - Airframe hours: 6900 - Engines: ALLISON 250-C20 B/J 420 horsepower turbo shaft - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: John J.

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.
