Biman Bangladesh Airlines has filed a case against nine of its engineers, including chief engineer Debesh Chowdhury, over a technical glitch that forced a plane carrying Prime Minister Sheikh Hasina to make an emergency landing last month.
Biman suspended the staff based on reports submitted by three investigation teams.
On November 23, a VVIP flight carrying Prime Minister Sheikh Hasina was forced to make an emergency landing at Ashgabat International Airport in the capital of Turkmenistan en route to a UN water summit in Budapest, Hungary.
The plane was carrying 99 passengers including the premier, four cockpit crew, 20 cabin crew and four aircraft engineers.
The fuel pressure of the aircraft carrying the PM was abnormally falling due to a technical glitch, according to a Biman official.
Sources said there were some technical problems when the aircraft was flying over the Turkmenistan-Afghanistan border. After noticing the rapid decline in fuel pressure, the captain of the aircraft decided to make an emergency landing at the nearest airport, which was Ashgabat International Airport of Turkmenistan.
The aircraft safely landed for inspection and repairs. Four onboard flight engineers examined the engine and discovered a loose nut in the lubricant oil system. The engineers tightened the nut and replaced the lubricant oil.
After completing the repairs, the captain operated a test flight for a final check-up. The entire procedure took a little over four hours.
