From reading this thread I get the impression that:
1: there are a lot of tail rotor gear box failures because everyone seems to think that if the chip light comes on the damn thing is about to explode.
2: Everybody is flying in the circuit or at most a 20 miinute drive from the hangar.
So anyhoo it is 1 1/2 hours to sunset - you are 1 hour from home or anyplace else for that matter- it is -35C with a 30 knot wind. The tr chip light comes on.
What are you going to do?
