Narrative

2 1/2 MI ON FINAL AT GDL. GEAR DOWN/FLAPS 30. SMA CAME OUT OF NOWHERE. CAPT SAW IT LAST SECOND; PULLED BACK ON YOKE -- TOO LATE. THUMP HEARD AND FELT FOLLOWED BY 'MAYDAY; MAYDAY; MAYDAY;' THEN LOTS OF SPANISH. FLT CTLS OK AND SO PANEL OK. AIRSPD 140 KTS ON ILS. SO SCANNED AND DETERMINED OUTBOARD WING HOUSING ON OUTBOARD SIDE KNOCKED OFF. SO; RPTED WING/FLAPS OK. GAR INITIATED AND ON DOWNWIND; FLY-BY COORDINATED. FLY-BY SHOWED NO GEAR/FLAP/WING MALFUNCTIONS. UNEVENTFUL LNDG AT H PLUS 03. DEPLANING OF PAX WAS UNEVENTFUL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE VISIBILITY WAS GOOD WITH NO CEILING AT GDL. THE RPTING ACR ACFT HAD BEEN TURNED OVER THE TWR; BUT HAD NOT GOTTEN THROUGH THE FREQ CONGESTION. MOST OF THE TALK WAS IN SPANISH. THE ACR WAS FULLY CONFIGURED FOR LNDG WITH THE CHKLIST COMPLETE. BOTH ACFT WERE UNDER POSITIVE CTL; THE ACR FLYING THE ILS AND THE SMA MAKING A L TURN IN TO LAND. APPARENTLY ALL OF THE RADIO CHATTER IN SPANISH WAS DIRECTED AT THE SMA WHEN THE TWR CTLR REALIZED THAT THERE WAS AN IMPENDING MIDAIR COLLISION. THE SMA WAS TOLD TO GAR; AND WHEN HE DID SO; HE PULLED UP INTO THE ACR. THE SMA HIT THE ACR'S LNDG GEAR AND GEAR DOOR FROM THE L TO THE R AND ITS PROP CHEWED UP THE R OUTBOARD FLAP. THE SMA'S ENG HAD A SUDDEN STOPPAGE AND ITS L OUTBOARD WING PANEL WAS BADLY CRUMPLED. THE SMA LOST UP ELEVATOR AUTHORITY BUT WAS ABLE TO LAND IN A PLOWED FIELD. THE PLT; THE ONLY OCCUPANT; WAS ABLE TO WALK OUT UNDER HIS OWN PWR. THE SMA WAS NOT POINTED OUT TO THE ACR. THE SMA HAD NO XPONDER; SO THERE WAS NO TCASII WARNING. IT WAS DIFFICULT FOR THE ACR TO ESTABLISH COM WITH THE TWR AFTER THE INCIDENT AS THE TWR PERSON WHO HAD BEEN ON DUTY LEFT THE SCENE IMMEDIATELY. ANOTHER CTLR CAME ON THE LINE TO ASSURE THE ACR THAT THERE WERE NO GAPING HOLES AND THAT THE RWY WAS CLR OF DEBRIS. THE ACR'S LNDG WAS UNEVENTFUL. THE MEXICAN GOV HAS TAKEN FULL RESPONSIBILITY FOR THE SIT AND THE NTSB HAS DETERMINED THIS TO BE AN 'INCIDENT.'
