A B737-700 FLT CREW RETURNS TO THE GATE FOR AN INSPECTION OF ANOTHER ENG WHEN REALIZING THE SIGNED OFF BIRD STRIKE WRITE UP IN LOGBOOK SHOULD HAVE INCLUDED BOTH ENGS; NOT JUST #1 ENG; AT OAK; CA.

Narrative

UNSCHEDULED ACFT CHANGE IN OAK. TOLD BY FO FROM ACFT THAT WE WERE TAKING THE CHANGE DUE TO BIRD STRIKE INSPECTION THAT WOULD BE DONE WHEN WE ARRIVED IN OUR NEXT DEST. DID BAG DRAG FROM GATE X TO GATE Y IN OAK. GOT SAME DEBRIEF FROM OFF-GOING CAPT. DID WALKAROUND AND FOUND EVIDENCE OF BIRD IMPACT INSIDE #2 ENG AT 8 O'CLOCK POS WITH NO DAMAGE TO ANY OF THE BLADES. FOUND NO EVIDENCE OF BIRD IMPACT IN #1 ENG. I EXPECTED TO SEE BIRD STRIKE AND I FOUND ONE. WE PUSHED ON TIME. AFTER PUSH BACK WAS COMPLETED; THE CAPT AND I TALKED ABOUT THE BIRD STRIKE AND REALIZED THAT THE BIRD STRIKE WAS WRITTEN UP AS HAPPENING TO THE #1 ENG AND I HAD FOUND BIRD IMPACT IN THE #2 ENG. DECIDED TO RETURN TO GATE TO GET MAINT INSPECTION OF THE #2 ENG PRIOR TO GOING FLYING. I SHOULD HAVE REALIZED THAT MAINT WOULD CLEAN UP ANY EVIDENCE OF BIRD STRIKE AS PART OF THEIR INSPECTION ON #1 ENG. ALSO; SHOULD HAVE HAD THE CONVERSATION ABOUT WHICH ENG WAS WRITTEN UP PRIOR TO PUSHBACK. SUPPLEMENT INFO FROM ACN 590242: THE NEW ACFT NEEDED TO RETURN TO PHX FOR BIRD STRIKE BORESCOPE. AFTER PUSHBACK; IT OCCURRED TO ME THAT THE LOGBOOK SHOWED BIRD STRIKE ON #1 ENG. WE DOUBLE-CHKED LOGBOOK AND REALIZED THAT THE FO HAD FOUND A 2ND BIRD STRIKE! THE FLT PUSHED ON TIME THE 1ST TIME AND 20 MINS LATER THE 2ND TIME. CONTRIBUTING FACTORS: EXPECTATION -- THE OTHER CREW HAD TOLD US ABOUT THE BIRD STRIKE AND WE WERE THEREFORE EXPECTING TO FIND SOME EVIDENCE OF ONE ON THE PREFLT. IT WAS NOT UNTIL I STARTED TO THINK ABOUT THE TKOF BRIEFING; AND WHICH ENG TO PAY CLOSE ATTN TO; THAT I REALIZED THE FO HAD TALKED ABOUT A STRIKE ON #2 BUT THE LOG SAID #1. RUSHING -- WE WERE HURRYING TO GET NEW ACFT OUT ON TIME AND DID NOT TAKE TIME TO FULLY COMMUNICATE.
