I'm also in the group that doesn't think too highly of dealers using new units for parts. But, nothing you can do about it because that unit belongs to the dealer and they can do anything they please. However, if the unit is "floor planned" I guess it's possible that the bank holding the paper would really frown upon this practice.
There were some mentions of parts being taken off airplanes to use on another airframe. That's pretty common in the airline industry (and probably the military) and there are pretty strict regulations pertaining to record keeping, etc. The airline owns or has total control of the airframes and they can do whatever they want provided it's done per the appropriate regulation.
No so in the business jet side of the industry. There is no such thing as a airplane "sales lot" because most biz jets, probably all, are sold before they ever come off the assembly line. Once the owner takes delivery then the manufacturer or service center has no control over that airframe. So, parts swapping is an absolute no-no. I don't thing Mr. Big is going to allow a facility to borrow parts from his 50 million dollar plane. It's happened in the past and the outcome for the facility "borrowing" the parts was not good...and very, very expensive for them.
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
