Re: NE-40 

yes, that is why I asked you to double check it 

but only after the inspection 

EASA AD says: 

Required as indicated, unless accomplished previously: 

(1) Before next flight after the effective date of this AD, accomplish a onetime 

inspection of the leading edge of the LPC (fan) blades and 

determine if erosion is evident in accordance with accomplishment 

instructions of RRD NMSB 72-A 1777. 

(2) If, during the inspection as required by paragraph (1) of this AD, any 

erosion is detected, before next flight, repair the eroded leading edge in 

accordance with accomplishment instructions of RRD NMSB 72-A1777. 

(3) After a repair as required by paragraph (2) of this AD, before next flight, 

measure the repaired blade chordal width in accordance with 

accomplishment instructions of RRD NMSB 72-A1777. If the measured 

blade chordal width is outside the requirements as referenced in RRD 

NMSB 72-A 1777, before next fl ight, replace the complete set of LPC 

(fan) blades with a serviceable set of LPC (fan) blades in accordance 

with accomplishment instructions of RRD NMSB 72-A1777. 

(4) Within 30 days after accomplishment of the measurement as required by 

paragraph (3) of this AD, provide, for all repaired blades, the actual 

chordal width measurement to RRD, Service Engineering. 

So if you are OK with it please initial for me and pass it on 

thank you 

PS AI is looking into NE-18
