One of the mags went out on this plane a few weeks before the crash. I believe they switched mags from 09X to see if that fix the problem. Don't fly cheap ladies and gentlemen. Rip Colin. :(

RIP Colin, a very sad day. My condolences to Colin's family, my heart reaches out as my Son is also passionately flying at the same age.

To the Anon above, I have flown many hours in 09X: Sterling Aviation is a first class organization, with IMO top notch maintenance and flight instruction. The investigators will get to the true root cause, if you have factual observations please contact them.
