Details
Synopsis: WHILE IN THE PROCESS OF EXECUTING A PRECISION RADAR GCA, FLYING TIGER LINES, INC., FLIGHT 45, A DC-8-63F CARGO AIRCRAFT, CRASHED ABOUT 2,200 FEET SHORT OF THE THRESHOLD OF RUNWAY 18 AT NAHA AIR BASE AT 1136 LOCAL TIME, JULY 27, 1970. THE FOUR CREWMEMBERS AND ONLY OCCUPANTS DIED AS A RESULT OF THE ACCIDENT. THE WEATHER CONDITIONS AT NAHA WERE GOOD WITH SCATTERED RAIN SHOWERS, ONE OF WHICH WAS LOCATED IN THE VICINITY OF THE GCA MINIMUM ALTITUDE POSITION. BRIGHT AREAS OF SUNLIGHT EXISTED WHERE CLOUD COVER WAS ABSENT. THE NATIONAL TRANSPORTATION SAFETY BOARD DETERMINES THAT THE PROBABLE CAUSE OF THIS ACCIDENT WAS AN UNARRESTED RATE OF DESCENT DUE TO INATTENTION OF THE CREW TO INSTRUMENT ALTITUDE REFERENCES WHILE THE PILOT WAS ATTEMPTING TO ESTABLISH OUTSIDE VISUAL CONTACT IN METEOROLOGICAL CONDITIONS WHICH PRECLUDED SUCH CONTACT DURING THAT SEGMENT OF A PRECISION RADAR APPROACH INBOUND FROM THE DECISIONHEIGHT.
Recommendation: THE FEDERAL AVIATION ADMINISTRATION ISSUE AN ADVISORY CIRCULAR INCORPORATING EXCERPTS OF THIS REPORT, INCLUDING THE FINDINGS, STRESSING TO ALL INSTRUMENT AND AIRLINE TRANSPORT RATED PILOTS THE NEED FOR CONTINUOUS SURVEILLANCE OF FLIGHT INSTRUMENTS WHEN OPERATING IN INSTRUMENT METEOROLOGICAL CONDITIONS.

Safety Recommendation History
From: FAA
To: NTSB
Date: 5/4/1972
Response: (2) IN RESPONSE TO THE SECOND RECOMMENDATION THE FAA STATED "WE BELIEVE THIS IS SO BASIC THAT ALL INSTRUMENT RATED PILOTS ARE AWARE OF THE CRITICALITY OF STAYING ON INSTRUMENTS WHILE FLYING IN INSTRUMENT CONDITIONS. IT SEEMS TO US THE BASIC ISSUE IS ONE OF CREW DISCIPLINE, I.E., FAILURE TO ADHERE TO PROCEDURES ESTABLISHED BY THE FEDERAL AVIATION REGULATIONS (FAR'S), THE COMPANY, AND GOOD OPERATING PRACTICES." NOTE: ALTHOUGH NOT STATED EXPLICITLY, THE INTENT OF THIS RECOMMENDATION WAS TO HAVE THE ADVISORY CIRCULAR EXPLAIN THE EFFECTS OF THE GANSFELD CONDITION, SO THAT PILOTS WOULD BECOME AWARE OF ITS EXISTENCE. FURTHER, IT WAS HOPED THAT THEY WOULD INCLUDE SUFFICIENT INFORMATION FOR PILOTS TO SEE FOR THEMSELVES THE NEED FOR SOMEONE TO STAY ON THE INSTRUMENTS ALL THE WAY TO POSITIVE VISUAL CONTACT WITH THE RUNWAY. THIS RECOMMENDATION WILL BE A TOPIC FOR DISCUSSION AT THE BOARD'S HEARING INTO APPROACH AND LANDING ACCIDENTS TO BE HELD IN SEPTEMBER 1972.
