12.7 FATIGUE LIFE:
At maximum intervals of 500 hours the following components must be inspected for signs of fatigue crack
damage, particularly at holes, notches and joints. The parts should be inspected in detail by an approved
inspector using dye penetrant, radiographic, or visual high magnification methods. The ideal time to do the
fatigue inspections is during the wing strip-down (see servicing schedule). If no cracks/damage is found the parts
may be returned to service for up to a further 500 hours.

For the following small items, inspection is not practical and so replacement is strongly recommended at the
following times:

It is vitally important that the lifing & NDT of all
