I am passionate about making aircraft ownership affordable to nearly anyone who dreams about flying his or her own airplane. I released “The Educated Owner” video series nearly 20 years ago and, although I no longer recognize the youthful host in those videos, they remain a popular item on ApproachAviation.com because the lessons haven’t changed. The bottom line is that an educated and involved aircraft owner will likely fly a safer aircraft, and do so for less money. You can be frugal and safe at the same time, but it takes education and attention to detail. There are no shortcuts.
