The total flight hours of the three aircraft types in Tables 3.1 Tables 4.0 Tables 5.0 are estimated to be the figures shown below. The estimated figures related to commercial operations, or government operations to commercial standards, in ‘western countries’ (or the USA only for the C208), where the safety standards, and hence accident rates, may be expected to reflect those expected in Europe, are shown below:

The hours are those compatible with the latest event data available, i.e. end 2005 for the C208, 15 September 2006 for the PC-12 and 1 May 2005 for the TBM 700. The great majority of TBM 700 operations are private/corporate.

2.5 Power Loss Rate

The figures in 2.2 and 2.4 give indications of the Rate of Loss of Power events per million hours for all operations and relevant commercial operations (FAR Part 135 or equivalent); there may be a difference for the latter due to the higher regulatory standards applied. The overall and Commercial (in brackets) rates are:

37 (21) Loss of Power events in 8.147 6.053) million hours.

The overall Loss of Power Rate is 4.54 (3.47) per million hours.
