|FlyGy, remember that STARS is NOT a government-run agency like ORNGE. It is a non-profit Society, and depends on the public's donations to run its operations. If there was any money available for 'kickbacks', it would be easier for them to hire staff.
Having said that, it might be that STARS has been double-checking the issues AW has had with the tail frame - 5 reported crashes in the past year with a total of 14 dead could bring that kind of response.

I am looking forward to seeing STARS' new equipment in our area. Unfortunately, the calls themselves are not good news (particularly for the patients), but the crews and operations are top-notch!
