Narrative:
On short final to runway 16L smf, I (PNF) saw an object pass into the aircraft lights. Sound of impact heard. Immediately surmised it was a bird strike on aircraft. As we were on short final, my attention remained on aircraft flight path and airspeed. All remained normal. No abnormal engine characteristics noted or aircraft handling reported by captain (PF). Normal landing occurred. Upon taxi to gate, smell emanated from air conditioning vents. Turning off air conditioning resolved smell. Postflt inspection revealed bird impact on #2 (right) engine with 'shingling' on N1 fan blades, with visible debris from bird. Additionally, left trailing edge flap had impact damage with fist size dent and residual bird debris evident. Aircraft grounded. Required maintenance. In summary, as conditions were dark, we had no opportunity to avoid impact with birds. With the close proximity of aircraft to ground, attention remained on stable flight path and airspeed to complete normal landing.

Title: MLG CREW HAD MULTIPLE BIRD STRIKES ON APCH TO RWY 16L AT SMF. THE ACFT WAS DAMAGED AND TAKEN OUT FOR REPAIR.
Narrative: ON SHORT FINAL TO RWY 16L SMF, I (PNF) SAW AN OBJECT PASS INTO THE ACFT LIGHTS. SOUND OF IMPACT HEARD. IMMEDIATELY SURMISED IT WAS A BIRD STRIKE ON ACFT. AS WE WERE ON SHORT FINAL, MY ATTN REMAINED ON ACFT FLT PATH AND AIRSPD. ALL REMAINED NORMAL. NO ABNORMAL ENG CHARACTERISTICS NOTED OR ACFT HANDLING RPTED BY CAPT (PF). NORMAL LNDG OCCURRED. UPON TAXI TO GATE, SMELL EMANATED FROM AIR CONDITIONING VENTS. TURNING OFF AIR CONDITIONING RESOLVED SMELL. POSTFLT INSPECTION REVEALED BIRD IMPACT ON #2 (R) ENG WITH 'SHINGLING' ON N1 FAN BLADES, WITH VISIBLE DEBRIS FROM BIRD. ADDITIONALLY, L TRAILING EDGE FLAP HAD IMPACT DAMAGE WITH FIST SIZE DENT AND RESIDUAL BIRD DEBRIS EVIDENT. ACFT GNDED. REQUIRED MAINT. IN SUMMARY, AS CONDITIONS WERE DARK, WE HAD NO OPPORTUNITY TO AVOID IMPACT WITH BIRDS. WITH THE CLOSE PROX OF ACFT TO GND, ATTN REMAINED ON STABLE FLT PATH AND AIRSPD TO COMPLETE NORMAL LNDG.
