# NTSB NYC98LA139: Ross RV6A, N67KH, Hunter, NY, July 6, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 6, 1998, 13:00 local (17:00 UTC) - Place: Hunter, NY - Coordinates: 42.210239, -74.209197 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.2102&lon=-74.2092&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report December 31, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 39581 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC98LA139 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/39581/pdf - Page: https://openairdocs.org/ntsb/NYC98LA139 ## Probable cause the pilot's inadequate compensation for wind conditions, and failure to maintain directional control of the airplane. The gusty/variable wind condition was a related factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - weather condition - variable wind (contributing factor) - weather condition - gusts (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - In flight collision with object, landing - object - tree(s) ## Analysis The pilot was landing uphill on a gravel runway with variable/gusty winds. He reported the airplane encountered a gust of wind after touchdown, which raised the left wing. The pilot was unable to regain directional control before the airplane departed the runway. The terrain on the right side of the runway dropped below the level of the runway, and the airplane became momentarily airborne as it headed toward trees at runway height. Subsequently, it collided with the trees and was damaged. ## Factual narrative On July 6, 1998, about 1300 eastern daylight time, a homebuilt RV6A, N67KH, was substantially damaged while landing at the Hunter Mountain Airport, Hunter, New York. The certificated private pilot was not injured. Visual meteorological conditions prevailed for the local flight. No flight plan had been filed for the flight that was conducted under 14 CFR Part 91. In an interview, the pilot reported he was conducting practice short field landings to the runway, landing to the north. He had departed about 1250, and conducted one touch and go. The second approach was planned as a full stop landing. In the NTSB Aircraft Accident Report, the pilot stated: "...The left wing was picked up by a strong gust of wind from the S.W. [Southwest], which banked the plane right toward the tree line - close to runway. Tried left rudder and aileron control with full power, but did not have enough speed to keep the plane from trees on right. I cut ignition and master switch on contact.... During the interview, the pilot reported that due to the close proximity of the trees to the side of the runway, he had insufficient time to point the airplane down the runway prior to making contact with the trees. He added that as the airplane departed the runway to the right, the terrain dropped down. The airplane remained at runway height as it struck the trees. The pilot reported the winds had been variable at about 5 knots with gusts to 10 knots. The pilot reported that he had operated in and out of the airport for 8 years without a problem. The airport runway was a one-way runway, with landing uphill, and takeoffs downhill, unless there were strong winds from the south. ## Aircraft - Registration: [N67KH](https://openairdocs.org/deregistered/N67KH-2018-01-23), registration cancelled 2018-01-23, S/N 21441, built 1993 (OpenAirDocs) - Reported make and model: ROSS RV6A - Registry model: [Ross Herbert W VANS RV-6A](https://openairdocs.org/model/ross-herbert-w-vans-rv-6a) (registry code 056222T) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 21441 - Airframe hours: 350 - Engines: Lycoming O-360-A1A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Robert A.

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.
