FAN AND BOOSTER
(ALL) :
Visual inspection of the outlet guide vanes (OGV) is
performed on a regular basis depending on the MRB, or
MPD.
If defects are found, then an unscheduled inspection is
required.
Possible defects
:
- missing material.
- nicks, dents, pits or scratches, usually due to
ingestion of small foreign objects such as sand,
stones, dust, tarmac, etc.
- distortion, cracks and deformation, usually due to
heavier foreign object damage (FOD), such as
birds, ice, hail, tires, etc.
