The FAA is revising Advisory Circular AC 91-37A according to an article I read recently. The article stated that the FAA has not enforced its regs on this subject as strongly as it could have.
The article also stated, "The FAA has struggled for decades to explain why illegal charter is unsafe and illegal. And the irony about the revised AC is that the agency is still pulling its punches. To that point: “You may forego the protection of certain safety standards . . .” Why does the FAA hold back? Perhaps because the accident statistics persist in making Part 91 operations in turbine aircraft look safer than the charter alternatives. This is a sensitive subject within the FAA and the industry. So perhaps the agency can be forgiven for watering down that safety warning."
I guess I am just posting this to see if anyone with more info has an opinion on this statement.
