E.3 Description of maintenance operations The supplier should clearly describe the amount of dismantling required for each operation except when this is done at the manufacturers works, for example: - inspectio

15、n of turbine blading; - inspection of major shafts and discs including blade attachments. E.4 Location of maintenance operations The supplier should state where maintenance operations on major integral components will be performed, for example: - in position in the unic - in the manufacturers shop;

16、- at the site of installation; - at a repair centre. If operations are to be performed at a repair centre, the supplier should state if exchange or lease components are offered E.6 Operation and maintenance training requirements The supplier, if requested, should provide information on training faci
