Re: BA 747 Engine Fire
In June 1995, amongst other types BA operated 33 B737-200s, 31 B747-100 and 200 aircraft, 6 DC10 and 6 L1011s, not forgetting 6 Concordes: As an educated guess I would say that these fleet types required 33 to 50% more maintenance than today’s more modern fleet.
Add in to the equation a number of line stations that have been out-sourced, the closure of the Manchester maintenance hangar, selling the engine overhaul facility in Wales and the overall sum 9500 down to 6000 looks quite reasonable!
