Basic training results in pilot's suspension (9)
I believe the answer is:
grounding
'basic training' is the definition.
(I've seen this before)
'results in pilot's suspension' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for grounding that I've seen before include "Foundation of basic knowledge" , "hampering progress of high flier?" , "Basic training" , "keeping home" , "Rudimentary knowledge" .)
