According to the official from NAC’s engineering department, the Boeing aircraft which has been departed to Singapore for C-Check is expected to accomplished within a week.
The ‘9N-ACB’ is expected to arrive Nepal from Singapore on 3rd of September, 2017. 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.
With only the two Airbus under operation, NAC has pressure to manage its flight as two Boeing 757-2F8 are out of the flight operation.
In addition, another vintage Boeing 757 ‘9N-ACA’ is under the process of being auctioned. To handle this situation, NAC applied for the wet lease one A319/A320/A321 aircraft to enhance its international flight and release pressure on its two Airbus A320s. However, there were no any suitable negotiation between NAC and other Airlines for wet lease of one A319 aircraft which compelled NAC to cancel most of the flight operation on various international sectors.
Similarly, NAC has received seven bids for selling its old Boeing 757 ‘9N-ACA’ but the decision has not yet been made. Soon, the corporation would uplift all the necessary formal procedures of selling the aircraft to governmental level. As the Boeing 757 ‘9N-ACA’ has only some hours on its engine capacity and after that both the engine must be changed. NAC Boeing 757 series aircraft burns 4 tones fuel each hour which are only 2.5 tones burned by a new aircraft. NAC has also decided to conclude its second Boeing 757 operation by 2019.
Following the decision of the sale of 9N-ACA, the corporation is all set to purchase two wide body aircraft A330-200 and two narrow body aircraft A320-233.
