Built in 1979 for the Soviet AF, this AN-26 was sold to Trast Aero in 2009, initally becoming ER-AUR but soon afterwards 4L-UCK. In 2010, the indonesian national logistics agency BULOG (for Badan Urusan LOGistics, responsible to secure food distribution during crisis) leased this airframe to run food from Sentani to the Baliem Valley. Trast Aero was founded in 2004 and was active till 2010, when its assets were taken over by Aquiline International based in Sharja (UAE). In 2014, 4L-UCK was converted to AN-26B and registered as EY-325. It was observed falling apart at Sentani airport in 2022.
