NTSB: Huge Gust of Wind Before Deadly Helicopter Crash on Kauai

Deadly Kauai Helicopter Crash

A “huge” and sudden gust of wind was reported just prior to a deadly helicopter crash on Kauai on July 11th, 2024, according to a preliminary report by the National Transportation Safety Board (NTSB). The crash off the island’s Na Pali Coast claimed the lives of the pilot and two passengers on a sightseeing tour of the island. The accident involved a Robinson R44 helicopter operated by Ali’I Air Tours.

According to the report, witnesses hiking along the Kalalua Trail on the Na Pali Coast reported strong, gusty wind conditions at the time of the accident. They described a sudden, powerful gust followed by a loud bang. The witnesses then saw the helicopter break apart mid-air, with the main fuselage and the tail boom section plummeting into the ocean about a quarter mile offshore. The wreckage sank quickly upon impact with the water.

The U.S. Coast Guard conducted an extensive underwater search using side-scan sonar technology, leading to the discovery of the severed tail boom in approximately 77 feet of water. However, the main fuselage has yet to be located.

An initial analysis by an NTSB senior meteorologist indicated that a strong pressure gradient along Kauai’s north shore contributed to strong, gusting easterly winds. A comprehensive weather study is pending to provide further insights into the conditions that led to the accident.

A follow-up underwater search and recovery operation is being planned. Once the wreckage is retrieved, the NTSB will conduct a thorough examination with the help of a helicopter aerospace engineer and other relevant parties.
