NTSB summary

HISTORY OF FLIGHTOn July 11, 2024, about 1305 Hawaii standard time, a Robinson R44 helicopter, N144KW, sustained substantial damage when it was involved in an accident near Kekaha, Hawaii. The pilot and two passengers were fatally injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 91 air tour flight. The helicopter was owned by Aloha Helicopter Tours LLC and being operated by Ali’I Air Tours for air tours on the island of Kauai. The helicopter departed from the Lihue Airport (LIH) at about 1231 for a 1-hour tour of the island of Kauai. According to archived ADS-B data, after the helicopter departed from LIH, it initially proceeded west-southwest before turning to a northerly heading. As the helicopter neared the northern shoreline of the island of Kauai, archived ADS-B data ended. ADS-B coverage along the northern coast of Kauai is limited due to mountainous terrain. Witnesses hiking on the Kalalua trail, along the Na Pali coast on the northern shore of Kauai, reported that during a brief rest stop overlooking the coast, strong gusting wind prevailed. They reported that, as they rested, a “huge” and sudden gust of wind blew over them, followed by a very loud “bang” noise. As their attention was drawn to the source of the loud noise, they saw the helicopter wreckage freefalling into the ocean in two sections: a main fuselage section and the tail boom section. The witnesses said that the helicopter wreckage sank moments after striking the water about one quarter of a mile offshore. The U.S. Coast Guard located the wreckage in about 77 ft of wa

Probable cause

An encounter with turbulence due to downdraft winds that resulted in mast bumping and an in-flight breakup.

    Phase and cause come from the NTSB’s own coding of each accident, which only exists from 2008 on, so these two filters leave out 1982–2007. Cause categories are only recorded for some accidents, and early findings can change.
