# NTSB NYC00LA026: Bailey Exec 162F, N14JJ, Pottstown, PA, November 6, 1999 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: November 6, 1999, 11:40 local (16:40 UTC) - Place: Pottstown, PA - Coordinates: 40.250205, -75.640838 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.2502&lon=-75.6408&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report March 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 47794 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC00LA026 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/47794/pdf - Page: https://openairdocs.org/ntsb/NYC00LA026 ## Probable cause The student pilot's loss of control of the helicopter, his lack of recent experience, his lack of total experience, and his overconfidence in his personal ability. A factor in the accident was the student pilot's disregard of regulations. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, hover - in ground effect - weather condition - unfavorable wind (contributing factor) - aircraft control - not maintained, pilot in command (cause) - lack of total experience, pilot in command (contributing factor) - In flight collision with terrain/water, hover - in ground effect ## Analysis The student pilot was conducting an air taxi in his homebuilt helicopter, with his son onboard. He taxied about 1/4 mile, then turned the helicopter around to return to the point of departure. The helicopter hovered briefly in position, then 'oscillated,' and one of the rotor blades struck the ground. The helicopter did not have an airworthiness certificate, and the student pilot had not obtained operating limitations for it. At the time of the accident, the student pilot had about 11 hours of total flight time. The student pilot's last known flight had been over 8 months before the accident, and upon its completion, he received an instructor's endorsement to solo, valid for 90 days. The endorsement stated, in part, that the student pilot was competent for solo hover in winds no greater than 5 mph. Weather, recorded at the accident site 14 minutes after the accident, included winds at 12, gusting to 17 knots. According to 14 CFR Part 61, paragraph 61.89(a): 'A student pilot may not act as pilot in command of an aircraft...that is carrying a passenger.' ## Factual narrative On November 6, 1999, at 1140 Eastern Standard Time, a homebuilt Exec 162F, N14JJ, was substantially damaged while attempting to hover at Pottstown Limerick Airport (PTW), Pottstown, Pennsylvania. The student pilot and his passenger received minor injuries. Visual meteorological conditions prevailed at the time of the accident. No flight plan was filed for the personal flight, which was conducted under 14 CFR Part 91. According to a Federal Aviation Administration (FAA) Inspector, the student pilot stated that he was conducting an air taxi, with his son onboard. He taxied about 1/4 mile, then turned the helicopter around to return to the point of departure. The helicopter hovered briefly in position, then was hit with a gust of wind. The helicopter "oscillated," and one of the rotor blades struck the ground. A witness stated that he saw the helicopter as it began rocking, "like a boat in rough water." Then, it "suddenly crashed, throwing debris into the air." The helicopter did not have an airworthiness certificate, and the student pilot had not obtained operating limitations for it. The student pilot did not respond to requests for information, as required to be provided to the Safety Board by 49 CFR Part 830. At the time of the accident, it was estimated that the student pilot had about 11 hours of total flight time. The student pilot's last known flight was on February 19, 1999. On that date, he received an instructor's endorsement for solo flight, which was valid for 90 days. The endorsement stated, in part, that the student pilot was competent for solo hover in winds not greater than 5 mph. Weather, recorded at the airport 14 minutes after the accident, included winds from 270 degrees true, at 12, gusting to 17 knots. According to 14 CFR Part 61, paragraph 61.89(a): "A student pilot may not act as pilot in command of an aircraft...that is carrying a passenger." ## Aircraft - Registration: [N14JJ](https://openairdocs.org/deregistered/N14JJ-2018-01-02), registration cancelled 2018-01-02, S/N 3727 (OpenAirDocs) - Reported make and model: Bailey EXEC 162F - Registry model: [Bailey Donald J II ROTORWAY EXEC](https://openairdocs.org/model/bailey-donald-j-ii-rotorway-exec) (registry code 05607TX) (OpenAirDocs) - Category: Helicopter, amateur-built - Serial number: 001 - Engines: Rotorway RI 162F 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Donald 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.
