Nepal Airlines Corporation (NAC) has stopped flying on domestic routes after its only operational Twin Otter aircraft was grounded on October 13.
The national flag carrier grounded its 40-year old Twin Otter aircraft, with call sign 9N-ABB, after life of its right engine expired. NAC was flying the aircraft on more than two dozen domestic routes.
According to existing rules, NAC must overhaul its engines after 4,000 flying hours.
The aircraft had to be grounded as the NAC management failed to procure engines for the aircraft and two other grounded Twin Otter’s in time, according to a source at NAC.
Meanwhile, NAC has already signed agreement to procure six Twin Otter engines. As a per the agreement, South West Air Motive of the US will supply two engines while Burman Aviation of India will provide NAC four Twin Otter engines. NAC sources say the engines will arrive in Nepal within a week.
As per the agreement, both the suppliers had to supply the engines to NAC about a month ago.
