# NTSB NYC01LA087: Robinson R-22, N9077F, Islip, NY, March 10, 2001 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: March 10, 2001, 17:00 local (22:00 UTC) - Place: Islip, NY - Coordinates: 40.794998, -74.099998 - Nearby events: https://openairdocs.org/map.md?lat=40.7950&lon=-74.1000&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 1 uninjured - Status: Completed, report July 30, 2001 - Report: Approved by Office Director - Parties: FAA/FSDO-11 - NTSB case key (mKey): 51919 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC01LA087 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/51919/pdf - Page: https://openairdocs.org/ntsb/NYC01LA087 ## Probable cause The certified flight instructor’s inadequate supervision and delayed remedial action, which resulted in a roll-over. Factors in this accident were the crosswind condition and soft landing area. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Roll over, landing - weather condition - crosswind (contributing factor) - supervision - inadequate, pilot in command(cfi) (cause) - recovery from bounced landing - delayed, pilot in command(cfi) (cause) - terrain condition - soft (contributing factor) ## Analysis The certified flight instructor (CFI) and student pilot were practicing auto-rotations from a hover. According to the CFI, after the student pilot rolled off the throttle, he immediately raised the collective, instead of letting the helicopter settle. The helicopter also began to yaw to the left and the wind was 17 to 21 knots, blowing from right to left. The student pilot then made an abrupt input to the cyclic control and the left skid contacted the ground. He also applied "full up collective a little too early." The CFI said that the helicopter's left skid dug into the soft ground, and it began to roll over. He further stated, "When I realized the helicopter was about to pivot over, it was already too late...." The helicopter rolled onto it's left side, and the main and tail rotor blades contacted the ground. The CFI reported he had accumulated approximately 900 flight hours in helicopters, of which, about 800 hours were in the R-22. Winds reported at the airport, about the time of the accident, were from 290 degrees at 11 knots, with 19 knot gusts. ## Factual narrative On March 10, 2001, about 1700 Eastern Standard Time, a Robinson R-22, N9077F, was substantially damaged while landing at the Long Island Mac Arthur Airport (ISP), Islip, New York. The certificated flight instructor (CFI) sustained minor injuries, and a student pilot was not injured. Visual meteorological conditions prevailed and no flight plan had been filed for the instructional flight conducted under 14 CFR part 91.

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.
