One way of doing it

Nepal Airlines had a spot of bother with one of its Boeing 757s, so they tried to fix it by sacrificing two goats to the Hindu sky god Akash Bhairab.

I've done a few contracts for the Boeing Company and I have it on good authority that animal sacrifices are not encouraged as an air maintenance protocol.  Indeed, the only time I've seen it practiced in the West is aboard US Navy Nimitz class aircraft carriers at about 2 AM when the crew gets a bit desperate about getting the fighter plane engine to start.
