S'cuse me guys.
RJPilot, that link led to the NTSB's main page. I did a search on Sunbird. The oldest accident I found was in 2001. They were the usual assortment of student pilots and other pilots not knowing how to land an airplane properly in gusty winds. That school wasn't the only one where instructors didn't know how to teach landings. Is there a particular NTSB Identification Number that you could post?
Same types of problems another flight school in North Las Vegas had until they pushed yet another 100% turnover in their flight instructors. That same flight school didn't make the NTSB records when a student pilot ran out of gas and did a landing on highway 95. There's only a slight mention of an on-airport landing from an engine failure after the plane's engine quit AGAIN a few weeks later and caused substantial damage. That school just repainted the airplane and is covering the crash damage by repainting their entire fleet. As they crash, they get some repairs, and get repainted. Of course the one with the leaking fuel tanks ruined the orginal paint job, so a new job hid that problem too, for another few months. Don't worry, the airplanes show no damage history, just the 100 hour inspection and paint job.
I saw another flight school that thought maintenance was too expensive. Fortunately, the former owner came back and shook things up. That school, after two years of struggling, and a large infusion of cash, prospers today.
Another flight school with pristine airplanes and a large customer base, plus dedicated flight instructors and an excellent location: Two years later they closed their doors during the summer rush when EVERYONE wanted to learn how to fly. They were a good school too until the new owner ran it into the ground with full afterburner.
Now I have several clients that bring their own airplanes. I can refuse to ride in them if they are not airworthy. I must! It's my certificates and life at risk.
Safety? It's up to the individual pilot to choose rental locations that have well-maintained, clean, airplanes. Dirt is not an airworthiness item, however, it does tell a story about how much an owner CARES about the airplane.
Fly SAFE!
