# Sifnos helicopter crash investigation > Live situation record from CLSTR: https://clstr.news/situations/sifnos-helicopter-crash-investigation > Updated: 2026-08-21T18:12:43.000Z. Sources: 195. Developments: 4. A private Bell 206 helicopter, operated by Bellavia Aviation Services, crashed on the Greek island of Sifnos on August 17, 2026, killing all three occupants: British newlyweds Alexander Cromie (31) and Marie Ebert (30), and pilot Giorgos Raikos (53). The accident occurred during the couple’s honeymoon while the aircraft was traveling from near Athens to Sifnos. Witnesses reported hearing a “strange sound” and observing unusual rotor behavior before the helicopter lost control and burst into flames near the village of Exambela. Preliminary findings from the National Organisation for the Investigation of Air and Railway Accidents and Transport Safety point toward a mechanical failure, specifically a loss of thrust in the tail rotor. Investigators are focusing on a June 1st incident in Paros involving the same aircraft. During that event, the helicopter's main rotor had been secured with straps to protect it from wind; however, when the pilot restarted the aircraft, the straps were reportedly not fully removed, causing them to strike the rear of the helicopter. While the aircraft received a certificate of airworthiness on July 2nd following maintenance, authorities are investigating whether the June incident caused undetected strain or damage to the tail rotor components. A police-appointed committee is scheduled to conduct an inspection on Sifnos, after which the wreckage will be recovered and transported to Athens for a detailed technical examination. ## Claims - The crash occurred in the Tholos area of Sifnos near a helipad.
