Details
Synopsis: THE NATIONAL TRANSPORTATION SAFETY BOARD HAS COMPLETED ITS INVESTIGATION AND REPORT OF THE MIDAIR COLLISION BETWEEN AERONAVES DE MEXICO (AEROMEXICO) FLIGHT 498, A DC-9-32, AND A GENERAL AVIATION PIPER PA-28-181, WHICH OCCURRED OVER CERRITOS, CALIFORNIA, ON AUGUST 31, 1986. AEROMEXICO FLIGHT 498 WAS OPERATING UNDER INSTRUMENT FLIGHT RULES (IFR) DESTINED FOR THE LOS ANGELES INTERNATIONAL AIRPORT ON A SCHEDULED PASSENGER FLIGHT FROM TIJUANA, MEXICO. THE PA-28 WAS CLIMBING UNDER VISUAL FLIGHT RULES (VFR) AFTER DEPARTURE FROM TORRANCE, CALIFORNIA. THE COLLISION OCCURRED ABOUT 8 MILES BEYOND THE POINT AT WHICH FLIGHT 498 CROSSED THE BOUNDARY OF THE LOS ANGELES TERMINAL CONTROL AREA (TCA) NEAR 6,500 FEET MEAN SEA LEVEL. BOTH AIRPLANES FELL TO THE GROUND WITHIN THE CITY LIMITS OF CERRITOS. FIVE HOUSES WERE DESTROYED AND SEVEN OTHER HOUSES WERE DAMAGED BY AIRPLANE WRECKAGE AND POSTIMPACT FIRE. FIFTY-EIGHT PASSENGERS AND 6 CREWMEMBERS ON THE DC-9, THE PILOT AND 2 PASSENGERS ON THE PA-28, AND 15 PEOPLE ON THE GROUND WERE KILLED IN THE ACCIDENT.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE TRANSPONDER EQUIPMENT WITH MODE C ALTITUDE REPORTING FOR OPERATIONS AROUND ALL TERMINAL CONTROL AREAS (TCAS) AND WITHIN AIRPORT RADAR SERVICE AREAS (ARSAS) AFTER A SPECIFIED DATE COMPATIBLE WITH IMPLEMENTATION OF TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) REQUIREMENTS FOR AIR CARRIER AIRCRAFT.

Safety Recommendation History
From: NTSB
To: FAA
Date: 5/3/1989
Response: We are pleased that on June 17, 1988, the FAA issued a final rule (Docket No. 25531, Amendment No. 91-203) establishing requirements for an aircraft to have an operating transponder with automatic altitude reporting equipment (Mode C transponder) when operating in the vicinity of certain primary airports for which a terminal radar approach control service area has been established, and in other airspace at and above 10,000 feet mean sea level (MSL). Specifically, effective July 1, 1989, all aircraft are required to have a transponder with Mode C when operating within 30 miles of any designated TCA primary airport from the surface to 10,000 feet MSL. Also, aircraft operating in all airspace of the 48 contiguous states and the District of Columbia at and above 10,000 feet MSL must be equipped with an operable transponder with Mode C except when operating at and below 2,500 feet above ground level. Additionally, effective December 30, 1990, all aircraft operating in an ARSA and in all airspace above an ARSA beginning at the ceiling of that ARSA and extending upward to 10,000 feet MSL within the lateral confines of that ARSA must be equipped with an operable transponder with Mode C. We believe that these changes will significantly reduce the potential for midair collisions. This recommendation is now classified as "Closed--Acceptable Action."

Date: 8/5/1988
Response: ON JUNE 17, 1988, THE FAA ISSUED A FINAL RULE (DOCKET NO. 25531, AMENDMENT NO. 91-203) ESTABLISHING REQUIREMENTS FOR AN AIRCRAFT TO HAVE AN OPERATING TRANSPONDER WITH AUTOMATIC ALTITUDE REPORTING EQUIPMENT (MODE C TRANSPONDER) WHEN OPERATING IN THE VICINITY OF CERTAIN PRIMARY AIRPORTS FOR WHICH A TERMINAL RADAR APPROACH CONTROL SERVICE AREA HAS BEEN ESTABLISHED, AND IN OTHER AIRSPACE AT AND ABOVE 10,000 FEET MEAN SEA LEVEL.

From: NTSB
To: FAA
Date: 3/17/1988
Response: On September 16, 1987, the Safety Board responded to Notice of Proposed Rulemaking, Notice No. 87-7, Docket No. 25304. Pending issuance of the final rule, this recommendation is classified as "Open--Acceptable Action."

From: FAA
To: NTSB
Date: 10/19/1987
Response: THE FAA PUBLISHED AN NPRM, DOCKET NO. 25304, NOTICE NO. 87-7, IN THE FEDERAL REGISTER ON 3/16/87. THIS NPRM PROPOSES TO REVISE THE REGULATIONS CONCERNING MODE C EQUIPMENT REQUIREMENTS FOR OPERATING IN AND AROUND TERMINAL CONTROL AREAS. I WILL PROVIDE THE BOARD WITH A COPY OF THE FINAL ACTION AS SOON AS IT IS PUBLISHED.
