opening in the market for someone there!
that is hardly going to happen in the world of helicopters.
the cost of liability insurance would be prohibative.
Also, Frank is able to control the market somewhat, by prohibiting the fitting of "unauthorized" parts to his helicopters.
Doing so would void any insurance you may have, and upset the authorities somewhat.
It would only take one prang atributed to the failure of one of the after market part, and that would be the end of that particular supplier.
