Narrative:
Low pressure compressor (lpc) module installation. Continuation of installation of lpc. During first attempt; resistance was met; pulled lpc back out to check the area of number 1 bearing support and lubricate all the o-rings for ease of installation and checked for any abnormalities. Nothing was found; so I decided to continue the installation the second time. Resistance was met again because of uneven push on the lpc; so I decided to use a strap and turnbuckles on both sides to draw it in; to even the push of bringing it in; so I could installed the bolts; still resistance is met during installation. Decided to pull it out again and found damage to the bleed valve duct area and the lpc. Notified the lead; supervisor and the inspector.
