From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

(.4)the pilot stated that he held his flare too long during a practice autorotation and allowed the tail to contact the ground. (-23)ANC98LA037 (.19) on April 12, 1998, at 1430 Alaska daylight time, an Enstrom F-28F helicopter, N199LB, sustained substantial damage during a hard landing at the Haines Airport, Haines, Alaska. The commercial certificated helicopter pilot sustained minor injuries. The flight was conducted under 14 CFR part 91, and departed Haines at 1425 as a local training flight. Visual meteorological conditions prevailed at the time of the accident, and a flight plan was filed with the pilot's company. During an interview with the nbsb investigator on April 13, 1998, the pilot stated he was practicing autorotations in preparation for an upcoming flight instructor flight test. He indicated the 15 to 20 knot winds were aligned with the runway. During the autorotative flare, the helicopter tail skid contacted the runway, and the helicopter la nded hard. The tail rotor gear box subsequently separated, and two main rotor blades contacted the tail boom.
