P7 also mentioned 'carby ice' . The Tobago engine mark and model are not quoted in the ATSB blurb - but I seem to remember they used the carburetor 'O' (opposed) 360 version. This was a cold, damp (foggy?) morning - if the aircraft had developed carb ice - that may be another explanation. Although it's hard to see just how CI formed at TOff power. Too many forgotten lessons, must have a read up.

There, quick memory jog - certain condition serious ice possible at 'any' power setting.

Murphy never rests - what a scenario - VFR into IMC  and Carby ice to boot. Im not suggesting this is what happened - not at all - but Golly, it makes you think - I hope.

Toot - toot.
