The 2009 Medair TC-HEK helicopter crash occurred on March 25, 2009 at around 16:00 EET (14:00 UTC) when a Bell 206L-4 LongRanger, tail number TC-HEK, operated by Medair while on a charter flight en route from Çaglayancerit in Kahramanmaras Province to Yerköy in Yozgat Province struck Mount Kes in central Turkey. The pilot and four passengers, including the leader of the Great Union Party (BBP) Muhsin Yazicioglu, were killed in the accident. Only one passenger survived the crash with injuries and made an emergency call. Due to harsh weather conditions at the crash site, the victims and the wreckage could be recovered only after two days, and the injured passenger was found dead five days later under snow.
