An Airbus A320-232 operated by THY Turkish Airlines sustained substantial damage in a landing accident at Istanbul-Atatrk International Airport (IST), Turkey. The aircraft operated flight TK1878 from Milano-Malpensa Airport (MXP), Italy, where it departed at 07:00 hours local time (05:00 UTC). At 10:23 hours local time (07:23 UTC) the aircraft carried out an approach to runway 05 at Atatrk Airport. The landing was discontinued and the airplane briefly climbed to 3800 feet. Flames were observed coming from (near) the no. 2 engine as the aircraft climbed away after the aborted landing. The airplane descended to 1100-1250 feet as it circled over sea in preparation for an approach to runway 35L. The A320 touched down on runway 35L at 10:41 hours local time. During this landing the right hand main gear collapsed, causing the no. 2 engine to drag along the runway. It swung to the right almost 180 degrees before coming to rest off the side of the runway.
