TooHotToFly:
Precision with data is crucial. I too was imprecise with my statement about night vs day flying.
The NTSB database shows IFR night flying to have a greater number of accidents than day IFR. The denominator, ie hours flown, is a matter of choice because of the way flying hours are documented. Thus a prevalence for accidents in these 2 categories is difficult to arrive at and thus a direct yes/no comparison isn't possible. Interestingly the Cessna 210 has such a high accident rate at night that it equals that of all other singles in the US.
Whether or not the UK AAIB figures are similar or completely different I do not know, but a comparison would be interesting. The data may be 'out there' but the analysts are often not pilots and are looking at the figures with a completely different mindset.
