The Aircraft Museum, the second of its kind in Nepal, is in Sinamangal and is a unique museum for aviation enthusiasts. The museum is situated inside the Airbus A330-300 of Turkish Airlines that flew for about eight months before experiencing a crash landing at the Thribhuwan International Airport in the year 2015. After dismantling and renovating the model Civil Aviation Authority Nepal along with Bed Upreti Trust re assembled the aircraft to put together the museum.

The museum's one-of-a-kind structure provides visitors with an experience unlike any other. Through a series of photographs, the museum hopes to provide visitors with information and knowledge about the aviation industry and aircrafts. About 350 miniature models of aircrafts can also be seen inside the museum.

Aside from that, its goal is to encourage Nepal's younger generation to participate in and be interested in aviation and its practices. The museum chronicles the history of Nepali aviation and other interesting things related to the topic making it a wonderful escape for curious minds. All proceeds from the museum goes towards assisting cancer patients.
