The cost model of a commercial operation is far different than GA private ownership: Internal maintenance or transient maintenance, bulk hangars or parking on ramp, 100 hrs, flying 50-150 hours/month, 18-22 year olds fresh out of school beating them up, etc. That’s not the question of this thread, hence why I “brushed it off.” I’m used for assessing safety and community culture. The community tends to respond to my presence differently than when feds come around. The culture of airports varies so much; people seem to self-segregate in the community that they fit or develop with the community. It’s quite interesting that each airport is different. I’d love to get some work in Alaska and see how that is! I’ve been used as expert witness in court and consulting for FSDO/NTSB investigations more times than I can count. Never has anyone asked me about cost/hour. The questions is: 1) any GA small piston owners that have thoroughly tracked costs per hour? For some reason people came out like a brick wall once I persisted with the question as if I’m raining on their parade. I’ve been clear GA ownership is worth it for pride of ownership and convenience. However, many people do enter ownership from a financial reasoning whether to avoid rental costs or a parent buying a plane for a kid to do a commercial in. Never have I met someone who ended up happy who bought a plane to save money. I was hoping to have some real world data to share with people. But there seems to be a community consensus that this question is off topic. I brought up regulatory non-compliance because in my experience most, if not all, *intentional* non-compliance comes from avoiding costs. Overall, most non-compliance stems from ignorance. Hence why we’ve switched from violations to education. Thank you for helping make Ferrari ownership affordable! FChat community is great.
