Looking on G-INFO, for example, the recorded hours for G-BNLI are 106,406 as at 31 December 2012. She was registered on 19 April 1990, so that's about 22½ years. That makes it just under 13 hours per day.
Probably a higher average time for the young aircraft that have not been into heavy maintenance. For example, the baby of the fleet G-STBF is recorded as 4,591 hours as at 31 December 2012. Registered on 21 February 2012, that makes it an average of just over 15 hours per day.
Although not much more hours in the three months since: only about 570.
One thing though - the engine on the wings are not necessarily the same all the 23 year - there might have been an engine swap.
