Narrative:
Called out to inspect 1 air carrier X aircraft after bird strikes. At the time, I was doing brake ride for another airline and maintenance on yet another airline. Arrived at air carrier X at XA00 hours to do cursory check and make sure no major damage requiring air carrier maintenance team. Write up was 'a bird strike to the airplane, just below cockpit L1 window.' inspected aircraft and found bird had struck radome in front and below captain's window. Also bird had struck in front of L1 door. I looked at cockpit windows from the ground but did not see any other bird strikes using my flashlight. Cockpit was dark (no lights on in aircraft). Inspected rest of aircraft -- engine, wings, tail, flaps, landing gear, etc. No other strikes noted. Went to other air carrier X aircraft, Y, and inspected it. Returned to another airline to replace engine starter there and other maintenance. Returned to air carrier X and aircraft Y at XC50 hours. Got ladder, cleaned and checked bird strike areas at radome and front of L1 door. Called air carrier X maintenance control to relay inspection results and logbook. Finished at XD20 hours. Approximately XF00 in the morning, mechanic was called out to aircraft X to clean captain's windshield of bird remains (blood and guts). Captain questioned logbook sign off. Evidently I missed 1 bird strike, and did not clean and inspect. Contributing factors: illness, causing interruptions in work to use restroom. Fatigue, caused by illness and hours on job. Poor lighting on ramp and too bright background lights. Corrective actions: be more attentive, make sure to look out windshields from inside aircraft using good lighting. Use ladder tall enough to see inside cockpit without reflections, with good lighting. Don't work when ill. Don't be distracted. Call for additional help when overwhelmed with tasks.

Title: A B737-500 WHICH INCURRED SEVERAL BIRD STRIKES HAD A BIRD STRIKE CHK. THE CHK WAS NOT ACCOMPLISHED PER THE MAINT MANUAL.
Narrative: CALLED OUT TO INSPECT 1 ACR X ACFT AFTER BIRD STRIKES. AT THE TIME, I WAS DOING BRAKE RIDE FOR ANOTHER AIRLINE AND MAINT ON YET ANOTHER AIRLINE. ARRIVED AT ACR X AT XA00 HRS TO DO CURSORY CHK AND MAKE SURE NO MAJOR DAMAGE REQUIRING ACR MAINT TEAM. WRITE UP WAS 'A BIRD STRIKE TO THE AIRPLANE, JUST BELOW COCKPIT L1 WINDOW.' INSPECTED ACFT AND FOUND BIRD HAD STRUCK RADOME IN FRONT AND BELOW CAPT'S WINDOW. ALSO BIRD HAD STRUCK IN FRONT OF L1 DOOR. I LOOKED AT COCKPIT WINDOWS FROM THE GND BUT DID NOT SEE ANY OTHER BIRD STRIKES USING MY FLASHLIGHT. COCKPIT WAS DARK (NO LIGHTS ON IN ACFT). INSPECTED REST OF ACFT -- ENG, WINGS, TAIL, FLAPS, LNDG GEAR, ETC. NO OTHER STRIKES NOTED. WENT TO OTHER ACR X ACFT, Y, AND INSPECTED IT. RETURNED TO ANOTHER AIRLINE TO REPLACE ENG STARTER THERE AND OTHER MAINT. RETURNED TO ACR X AND ACFT Y AT XC50 HRS. GOT LADDER, CLEANED AND CHKED BIRD STRIKE AREAS AT RADOME AND FRONT OF L1 DOOR. CALLED ACR X MAINT CTL TO RELAY INSPECTION RESULTS AND LOGBOOK. FINISHED AT XD20 HRS. APPROX XF00 IN THE MORNING, MECH WAS CALLED OUT TO ACFT X TO CLEAN CAPT'S WINDSHIELD OF BIRD REMAINS (BLOOD AND GUTS). CAPT QUESTIONED LOGBOOK SIGN OFF. EVIDENTLY I MISSED 1 BIRD STRIKE, AND DID NOT CLEAN AND INSPECT. CONTRIBUTING FACTORS: ILLNESS, CAUSING INTERRUPTIONS IN WORK TO USE RESTROOM. FATIGUE, CAUSED BY ILLNESS AND HRS ON JOB. POOR LIGHTING ON RAMP AND TOO BRIGHT BACKGROUND LIGHTS. CORRECTIVE ACTIONS: BE MORE ATTENTIVE, MAKE SURE TO LOOK OUT WINDSHIELDS FROM INSIDE ACFT USING GOOD LIGHTING.
