Surface temp/ dew point +5/+5 at elevation 502 feet.
If airmass was saturated, then the temp at 3000ft, 2500 above field elevation may have been approx +1.25 degrees, assuming lapse rate of 1.5/1000ft.
The aircraft was in this airmass for over 50 mins prior to the 3rd approach.
Any TP operators like to educate an ex-turbofan driver of the likelihood of engine icing in such conditions which might affect the Garrett?
I assume the investigation has looked at this but I have failed to find, or have missed, any reference to the possibility.
