We also found the company was cited nearly five years ago by the Federal Aviation Administration.
TransPac Aviation Academy was certified in 2007.
Since then, the FAA has recorded 20 accidents and incidents at TransPac and even issued an enforcement action against the company in 2009.
The FAA said Transpac violated three regulations. One focused on quality of training for the school's approved training course. Another involved instructor responsibilities, like making sure each student conducted tests at the end of training.
The last one involved maintaining school standards.
James Timm with the Arizona Pilots Association says it's important to keep in mind that the school deals with a huge volume of flights every day and hundreds of student pilots.
"You have to really put that into perspective by the number of students that they have that are going through there, over that length of time. And goodness, you put it in perspective and I don't think it's a horrendous number," Timm said.
The FAA tells us it does periodic inspections of flight schools that are certified.
TransPac officials say "the safety and security of its instructors and students" are a priority.
