Anyone remember the name of that movie about the dodgy South American operator?
Zulu Whiskey Foxtrot?
Aside:
The problem;
"If you don't want to do it I'll find someone who will"
The priciple;
People are paying money to get to their destination in one piece.
This means they, often unknowingly, are relying on the experience and judgement of the pilot to keep them from harm, be it by for example knowing the limitations if weather is an issue or, as this thread is leading, the aircraft is unserviceable.
The short term result;
When something goes south, the employer WILL NOT stand up and say, "I made the pilot fly."
You WILL be blamed as PIC.
The long term result;
It's a small industry. If you choose to operate outside the rules long term with this operator, don't think people don't know. The operator's reputation tends to follow the pilot, good AND bad.
