Sportcruiser - Opinions?

This is a fatal accident due to an under-performance PA28-140 that led AAIB to recommed to EASA periodic performance assessment of aircraft. So far, I think that EASA has ignored this, whilst UK CAA was doing it already.

I think cutting open the oil filter (which is supposed to happen) would have been more useful.

Apologies, Genghis - when you said this:

'912 series engines have the option to change gear ratio as well'

I thought you were referring to the 912s which are four strokes...

(PS Never have sussed how to do the 'quote' thing. Doh!)

The 912 is also a 4-stroke, and so far as I know the most common Rotax 4-stroke, about which you posted:

80hp 912 is normally 2.27:1 with 2.43:1 as an option.

.

So you I said that 912 series engines have a gear ratio option, and you said that the 912 has a gear ratio option. Perhaps we can just agree that the 912 has a gear ratio option.

Mistakes do occur in maintenance of-course, and an air test is one mechanism for picking those up.

Unfortunately, some of the mistakes, not picked up, eventually get reported on by AAIB! That however can't ever be the preferred option.
