Boeing 757 ‘9N-ACB’ has been grounded at Nepal Airlines Corporation (NAC) hangar for more than 10 days following a technical glitch in the engine. As per the official from NAC’s engineering department, the Boeing aircraft received crack in its engine mount and is under full inspection.
The spokesperson for NAC Rabindra Shrestha said, “Engineering team from Singapore Technology (ST) Aerospace and Nepal Airlines is jointly working to repair the faulty aircraft. Engineers are trying their best to complete the maintenance work as soon as possible.” The Boeing 757 ‘9N-ACB’ will depart to Singapore by this month for C-Check, he added.
C-Check is the advanced maintenance check requiring a majority of the aircraft’s components to be inspected. It is performed approximately every 20-24 months or a specific amount of actual flight hours or as per the requirement details from the manufacturer. Due to the complexity of C-check, it is carried out in a hangar at a maintenance base having huge space.
Due to the occasional grounding of Boeing 757, NAC’s international flight is being disturbed and the pressure is building upon its two Airbus A320s. Moreover, the C-Check of Boeing 757 requires a minimum of 2 weeks for the completion so, the corporation is trying to wet lease one A319/A320/A321 aircraft for a maximum of 60 days to enhance its international flight and release pressure on its two Airbus A320s.
