A330 N2 cranking
well i'd like to ask u a technical question about RR trent700 engine which is fitted on A330
as we know dat during borscope insp we have to rotate N1 ,N2 & N3 as well , N1 can be rotated by fan blades, N3 can be rotated by removing air starter pump & then rotate it
(((or by removing hand cranking drive pad access panel which is located on da AGB frontface to crank it)))
.
my question is in trnt700 eng , from where we rotate N2 spool during borscope inspl ?
NOTE:
the info which
in red color
above is on A321 CFM56-5B eng's (for N2 hand cranking) , idk if its da same for trnt700 eng's or no , so correct me plz
another question , the pic bellow shows the hand cranking drive pad used during boroscope insp on A321 cfm56-5b eng , the question is when u crank from this position u crank N1 & N2 spools together or N2 spool only ?
