Details
Synopsis: EASTERN AIR LINES, INC., FLIGHT 9701, A BOEING 727-100, N8168G, WAS OPERATED AS A REGULARLY SCHEDULED CARGO FLIGHT ON DECEMBER 21, 1971. AT 0405 E.S.T. THE FLIGHT DEPARTED CHARLOTTE, NORTH CAROLINA, WITH ATLANTA, GEORGIA, AS THE DESTINATION. THE FLIGHT ENROUTE AND IN THE ATLANTA TERMINAL AREA WAS ROUTINE UNTIL AFTER THE AIRCRAFT PASSED THE OUTER MARKER INBOUND ON AN INSTRUMENT LANDING SYSTEM, CATEGORY II, APPROACH TO RUNWAY 9 RIGHT AT THE WILLIAM B. HARTSFIELD ATLANTA INTERNATIONAL AIRPORT. FLIGHT 9701 REPORTED OVER THE OUTER MARKER AT 0446. SHORTLY THEREAFTER AN ALARM IN THE ATLANTA AIRPORT TOWER SOUNDED, SIGNALING THAT THE APPROACH LIGHT SYSTEM WAS NOT FUNCTIONING PROPERLY. SUBSEQUENTLY, IT WAS DISCOVERED THAT N8168G HAD STRUCK THE NOS. 18, 17, 16, AND 15 LIGHT BARS OF THE APPROACH LIGHT SYSTEM BEFORE LANDING ON RUNWAY 9 RIGHT. CONTACT WITH THE APPROACH LIGHTS CAUSED MINOR DAMAGE TO THE LEFT INBOARD FLAPS AND SUBSEQUENT BLOWOUT OF THE TWO LEFT MAIN LANDING GEAR TIRES.
Recommendation: THE FEDERAL AVIATION ADMINISTRATION REQUIRE THAT AIR CARRIERS ESTABLISH PROCEDURES IN THEIR OPERATIONS MANUAL THAT WOULD REQUIRE THE PILOT WHO FLIES AN AIRCRAFT DURING APPROACHES IN LOW VISIBILITY CONDITIONS TO MONITOR THE INSTRUMENTS CONTINUOUSLY UNTIL THE RUNWAY THRESHOLD, OR RUNWAY LIGHTS ARE CALLED IN SIGHT.

Response: 9/8/72 - FAA ADVOCATE THERE IS NEED TO CONTINUE MONITORING FLIGHT INSTRUMENTS IN MODERN TURBOJET AIRPLANES ALL THE WAY INTO THE FLARE.AC 120-29 (CRITERIA FOR APPROVAL OF CATEGORY I AND II OPERATIONS) REQUIRES THE ESTABLISHMENT OF CREW MEMBER DUTIES FOR APPROACH MONITORING AND THE MAXIMUM DEVIATION OF RAW DATA ILS INDICATIONS. AC 91-25A RECOMMENDS CONDITIONS UNDER WHICH THE APPROACH AND LANDING SHOULD BE ABANDONED. IT SPEAKS TO THE NEED FOR RUNWAY THRESHOLD OR RUNWAY LIGHTS TO BE IN SIGHT BEFORE CONTINUING DESCENT BELOW DH. THIS DOES NOT PRECLUDE OR PREVENT MONITORING OF THE FLIGHT INSTRUMENTS FOR GLIDE SLOPE, AIRSPEED AND RATE OF DESCENT CONTROL.
