## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

LATEST DATA SOURCE FOR THIS OCCURRENCE REFLECTS "-5" BUT THE FOLLOWING REMARK IS ACTUALLY FROM A .4. DUE TO SYSTEM LIMITATIONS, BECAUSE THE EVENT WAS TAGGED "C", WOULD NOT ACCEPT ".4" AS THE LATEST DATA SOURCE.  THIS IS ACTUALLY AN INCIDENT WHICH WAS INVESTIGATED BY NTSB.  ALSO NTSB'S REPORT REFLECTS A REGISTRATION # OF GCPX.  THE ACTUAL REGISTRATION # IS CGCPX. (.4)  ON DECEMBER 8, 1998, ABOUT 1725 EASTERN STANDARD TIME, A BOEING 737, C-GCPX, OPERATED BY CANADIAN AIRLINES INTERNATIONAL LTD. AS FLIGHT 528, EXPERIENCED A NEAR MIDAIR COLLISION WHILE MANEUVERING TO LAND AT LA GUARDIA AIRPORT (LGA), NEW YORK, NEW YORK.  THE AIRPLANE WAS NOT DAMAGED, AND THE 2 FLIGHT CREWMEMBERS, 4 FLIGHT ATTENDANTS, AND 46 PASSENGERS WERE NOT INJURED.  INSTRUMENT METEOROLOGICAL CONDITIONS PREVAILED AND AN INSTRUMENT FLIGHT RULES (IFR) FLIGHT PLAN HAD BEEN FILED FOR THE SCHEDULED PASSENGER FLIGHT THAT WAS CONDUCTED UNDER 14 CFR PART 129. ACCORDING TO THE DUTY CHIEF DISPATCHER FOR CANADIAN AIRLINES, THE BOEING 737 WAS ON DOWNWIND FOR LA GUARDIA'S RUNWAY 4, AT 4,000 FEET ABOVE MEAN SEA LEVEL (MSL), WHEN THE CREW CAUGHT A GLIMPSE OF THREE LIGHTS.  THE LIGHTS WERE RED, WHITE, GREEN, AND ALIGNED VERTICALLY  WITH THE RED LIGHT ON THE BOTTOM. THE DUTY CHIEF DISPATCHER ADDED THAT THE FIRST OFFICER SAW THE OTHER AIRPLANE AND HAD ENOUGH TIME TO REALIZE THEY WERE NOT GOING TO COLLIDE, BUT NOT ENOUGH TIME TO EXECUTE AN EVASIVE MANEUVER. IN ADDITION, THE AIRPLANE'S TRAFFIC ALERT COLLISION AVOIDANCE SYSTEM (TCAS) WENT FROM "TRAFFIC" TO "MONITOR VERTICAL SPEED" TO "CLEAR OF CONFLICT" IN APPROXIMATELY 2 SECONDS. ACCORDING TO THE FEDERAL AVIATION ADMINISTRATION'S (FAA) PRELIMINARY PILOT DEVIATION REPORT, THE OTHER AIRPLANE WAS A CESSNA 172, IFR, AT 5,000 FEET MSL.  THE PILOT OF THAT AIRPLANE APPARENTLY SAW THE BOEING 737 AT HIS 12 O'CLOCK POSITION AND PERCEIVED IT TO BE AT THE SAME ALTITUDE.  TO AVOID A PERCEIVED COLLISION, THE CESSNA PILOT EXECUTED A DESCENT, AND AT 4,000 FEET MSL, THE TWO AIRPLANES PASSED 0 FEET VERTICALLY AND 500 FEET HORIZONTALLY FROM ONE ANOTHER.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
