This poses almost as many questions as it answers.
A careful reading of the AC repeatedly references “Private Pilots”–but does ALSO references “exercising Private Pilot privileges.” Does the fact that I have an ATP, but also fly personally for fun, affect my ability to share expenses with passengers?
“Common purpose with passengers who are part of their family or social circle”. I fly a King Air as a corporate pilot. For 30+ years, my employers and I have had an arrangement–I can fly the airplane for my own use for simply the direct operating cost–fuel, navigation, landing and customs fees, hangar, etc.–but nothing for the aircraft. In addition to my own domestic trips, (about a dozen a year), I go to Canada a lot–hunting and fishing. I live in a SMALL CITY, and take friends with me–we all split the expenses. Over the years, some have dropped out–moved–or died. We–as a group–have found people known to members of the original group to replace them. Since I do not have an " ongoing, pre-existing relationship (e.g., family friends or close acquaintances)” with the “New Guy” on the fishing trip (but the rest of the group does), can we bring him along? Or do I need to make sure I “interact” with him for an unspecified period of time before the trip?
Both Canadian and U.S. Customs routinely ask “how do you all know each other?” It has never been a problem for Customs. (but then, Customs is NOT the FAA–they hardly acknowledge each other.)
The group (including me) shares the cost of the hunting or fishing trip–the food, lodge, boats, guide. Is this sufficient “common purpose?”
Reverting to my corporate pilot role–the owner of the King Air is very generous in the use of the airplane–he lets almost any charitable organization use it–sometimes for free–sometimes for the cost of the fuel (and no charge for me). I have no idea what the relationship of each passenger is to the company–only the charitable organization. I don’t even see the internal accounting. Do I have to have a company employee along to insure that it is “common purpose”–and that the others are either going for free or sharing direct operating costs?
Oddly enough, it would be easier for all of us to rent the local Baron for the trip and have me fly that instead–we can then qualify the entire cost through the rental rate on the aircraft–as opposed to Direct Operating Costs Only for the King Air. That may make it legal, but is it as safe?
“There aren’t enough words in the English Language to cover every scenario”–but that doesn’t keep the FAA from trying.
