### 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 lead i ng edge in accordance w ith accomplishment instructions of RRD NMSB 72-A1777
. (3) After a repair as requ i red by paragraph (2) of this AD , before next flight, measure the repaired blade chordal width i n 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 accompl ishment 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 Sincerely ,
