Narrative:
Inbound crew reported bird strikes to right side of aircraft. Further investigation found small birds had hit leading edge and trailing edge flaps near #2 engine and that #2 had ingested at least 1 bird down the core. Crew reported no fluctuations in #2 during event. I conferred with maintenance control who directed me to a maintenance card. I performed all relevant checks per amm 72-00-00 page B605-B613. I inspected the inlet cowl, inlet cone, lp compressor blades and no damage was found. The lp compressor section turned freely with no restrs and no odd noises. The lp compressor for case and outlet guide was checked good. I did find bird debris in the lp compressor stage 1.5 vanes and notified maintenance control. We deferred the engine for 2 cycles to facilitate a borescope inspection of #2 engine for bird ingestion. At my request, the crew ran #2 engine at idle for 5 mins to verify no further inconsistencies prior to the next leg. No deviations were noted. I created a carry forward item and released the aircraft. What I failed to do was to fully document that I had performed all required checks on the carry forward item. The aircraft was inspected after the next leg with no fault found during borescoping. This was brought to my attention during my regulatory training refresher class when I pulled up the item again and felt I had not properly documented the necessary steps per our maintenance operations procedure.

Title: AN A320 RPTED A BIRD STRIKE #2 ENG. INSPECTION REVEALED NO DAMAGE PER MAINT MANUAL PROC. BORESCOPE DEFERRED FOR 2 CYCLES. TECHNICIAN FAILED TO ENTER FULL DOCUMENTATION ON CHKS ACCOMPLISHED.
Narrative: INBOUND CREW RPTED BIRD STRIKES TO R SIDE OF ACFT. FURTHER INVESTIGATION FOUND SMALL BIRDS HAD HIT LEADING EDGE AND TRAILING EDGE FLAPS NEAR #2 ENG AND THAT #2 HAD INGESTED AT LEAST 1 BIRD DOWN THE CORE. CREW RPTED NO FLUCTUATIONS IN #2 DURING EVENT. I CONFERRED WITH MAINT CTL WHO DIRECTED ME TO A MAINT CARD. I PERFORMED ALL RELEVANT CHKS PER AMM 72-00-00 PAGE B605-B613. I INSPECTED THE INLET COWL, INLET CONE, LP COMPRESSOR BLADES AND NO DAMAGE WAS FOUND. THE LP COMPRESSOR SECTION TURNED FREELY WITH NO RESTRS AND NO ODD NOISES. THE LP COMPRESSOR FOR CASE AND OUTLET GUIDE WAS CHKED GOOD. I DID FIND BIRD DEBRIS IN THE LP COMPRESSOR STAGE 1.5 VANES AND NOTIFIED MAINT CTL. WE DEFERRED THE ENG FOR 2 CYCLES TO FACILITATE A BORESCOPE INSPECTION OF #2 ENG FOR BIRD INGESTION. AT MY REQUEST, THE CREW RAN #2 ENG AT IDLE FOR 5 MINS TO VERIFY NO FURTHER INCONSISTENCIES PRIOR TO THE NEXT LEG. NO DEVS WERE NOTED. I CREATED A CARRY FORWARD ITEM AND RELEASED THE ACFT. WHAT I FAILED TO DO WAS TO FULLY DOCUMENT THAT I HAD PERFORMED ALL REQUIRED CHKS ON THE CARRY FORWARD ITEM. THE ACFT WAS INSPECTED AFTER THE NEXT LEG WITH NO FAULT FOUND DURING BORESCOPING. THIS WAS BROUGHT TO MY ATTN DURING MY REGULATORY TRAINING REFRESHER CLASS WHEN I PULLED UP THE ITEM AGAIN AND FELT I HAD NOT PROPERLY DOCUMENTED THE NECESSARY STEPS PER OUR MAINT OPS PROC.
