On 26 September 2018, US-Bangla Airlines flight UBG-141, a B737-800 (S2-AJA), experienced nose landing gear extension failure on approach to Cox's Bazar. After diversion to Chattogram and a landing with nose gear up, all occupants were evacuated without serious injuries.

Summary of Events

On 26 September 2018, a Boeing 737-800 aircraft, registration S2-AJA, operated by US-Bangla Airlines Ltd. as flight UBG-141 (Bangla Star-147), was conducting a scheduled domestic passenger flight from Hazrat Shah Jalal International Airport (VGHS), Dhaka, to Cox's Bazar Airport (VGCB). The flight was uneventful until the approach to Cox's Bazar.

History of Flight

While on a straight-in final approach to runway 35 at Cox's Bazar, the flight crew lowered the landing gear lever but the nose landing gear did not extend, as indicated by the nose gear position indicator on the dashboard and overhead panel. The crew executed a go-around, recycled the landing gear, and performed the emergency checklist per the Quick Reference Handbook (QRH), but the nose gear remained up. A low pass was made to allow the tower to visually confirm that the nose gear was not down. Manual extension procedures as per the QRH also failed.

Consequently, the aircraft diverted to Shah Amanat International Airport (VGEG), Chattogram, anticipating better handling and medical facilities. The primary diversion airfield per the flight plan was VGEG, and remaining fuel was about 2.6 tons. En route, the crew again attempted manual extension but without success.

Emergency Response and Landing

The flight crew informed Air Traffic Control (ATC) at VGEG of the emergency and the possibility of a nose-gear-up landing. A low pass at VGEG confirmed the nose gear was not down. The captain briefed the cabin crew, and preparations were made. Fuel was reduced to as low as possible per the QRH. The landing was executed with flaps 40 degrees, touching down at the threshold of runway 23. The aircraft came to a stop about 300 feet short of the threshold of runway 06.

Evacuation

After stopping, an emergency evacuation was carried out per the QRH. All passengers and crew evacuated safely without any serious injuries, using emergency exits and main doors with escape slides deployed as applicable.
