First reaction ( just the beginning ):
GE will release 2ea new SB's for CF6-50s coming week, asking for an once thru the fleet action program,
including engine vibration surveys and special ultrasonic inspection of the LPT Stg.3 disk ( on-wing ).
Engines will be splitted into three categories ( 1 - 3 ) whereas most of the CF6-50 engines will likely fall into "cat 1",
which requires to carry out these actions within 15 cycles!!!after the effectivity date of SB.
FAA obviously considers to cover this requirement by AD Note asap.
This will be a major burden for all -50 operators!
Operators NDT inspectors haven't even been trained so far for this special inspection but several GE courses are setted up within the next two weeks.
This taff time schedule will become a challenging lesson for everybody!
And this is just the beginning......
