Biman flight 048 departed Dubai for a regular flight to Chittagong and Dhaka, Bangladesh. Weather at Chittagong was poor. When the DC-10 approached the airport (08:50 local, 02:50 UTC), the METAR read: VGEG 010250Z 18006KT 1800 RAIN BKN007 SCT013 FEW026CB OVC080 26/25 Q100 3 TEMPO S/VIS 2KM OR LESS= (wind 180 degrees at 6 kts, visibility 1800 m, rain, 5-7 oktas cloud at 700ft, 3-4 oktas cloud at 1300ft, 0-2 oktas cloud at 2600ft with thunder clouds 8 oktas overcast cloud at 8000ft, temperature 26C dewpoint 25C temporarily visibility 2 km). The aircraft touched down on runway 23 but ran off the right side of the runway, into the grass. The right hand undercarriage collapsed and the plane sank a meter-deep into the mud, causing the severe damage to the right hand wing and the separation of the no. 3 engine. The airplane came to rest 7300 ft from the runway 23 threshold. Chittagong has a single runway (05/23) which measures 9646 x 150 feet.
