Details
Synopsis: CARIBBEAN ATLANTIC AIRLINES, INC. (CARIBAIR), FLIGHT 340, A DOUGLAS DC-9-31, N938PR, WAS INVOLVED IN A LANDING ACCIDENT AT 1409 A.S.T.*,ON AUGUST 12, 1969, AT HARRY S TRUMAN AIRPORT, CHARLOTTE AMALIE, ST.THOMAS, VIRGIN ISLANDS. THE AIRCRAFT, ON ITS LANDING ROLLOUT, CONTINUED 323 FEET BEYOND THE FAR END OF RUNWAY 9, AND CAME TO REST IN AN AUTOMOBILE REPAIR SHOP, AFTER STRIKING SEVERAL VEHICLES. THERE WERE 114 PASSENGERS ABOARD AND A CREW OF FIVE. EVACUATION OF THE AIRCRAFT WAS ORDERLY, WITH ONE PASSENGER SUSTAINING MINOR INJURIES. THREE OCCUPANTS OF THE GROUND VEHICLES, WHICH WERE STRUCK BY THE AIRCRAFT AFTER IT LEFT THE RUNWAY, WERE SERIOUSLY INJURED ANDONE WAS SLIGHTLY INJURED.
Recommendation: 1. REEVALUATE THE ADEQUACY OF THE WET RUNWAY STOPPING DISTANCE REQUIREMENTS OF THE FEDERAL AVIATION REGULATIONS, AND 2. CONSIDER THE FEASIBILITY OF INCORPORATING THE NASA TRACTION TEST PROCEDURE IN REVISED WET RUNWAY LENGTH REQUIREMENTS FOR AIR CARRIER AND OTHER APPROPRIATE AVIATION OPERATIONS.

Response: 9/18/70 THE FAA STATED THEY HAVE BEEN WORKING WITH NASA, USAF AND THE AIR TRANSPORT INDUSTRY TO ESTABLISH APPROPRIATE CRITERIA AND STANDARDS REGARDING WET RUNWAY TRACTION AND ITS APPLICATION TO AIRCRAFT STOPPING DISTANCES. THEY HAVE ALSO BEEN CLOSELY ASSOCIATED WITH NASA TEST ACTIVITIES AND ARE CLOSELY FOLLOWING THE WORK NASA IS DOING ON WHEEL SPIN-UP UNDER HYDROPLANNING CONDITIONS AND CORRELATION OF RAIN RATE WITH DEPTH OF WATER ON A RUNWAY SURFACE. WITH REGARD TO THE BOARD'S RECOMMENDATIONS, THEY PROPOSE TO UTILIZE THE RESULTS OF NASA TESTS WITH THE DIAGONAL-BRAKED VEHICLE TO: 1. REEVALUATE FAR'S WET RUNWAY STOPPING DISTANCE REQUIREMENTS. 2. ESTABLISH THE NASA TRACTION TEST PROCEDURE, I.E., DIAGONAL-BRAKED VEHICLE, AS AN ACCEPTABLE PROCEDURE FOR ESTABLISHING RUNWAY CHARACTERISTICS UNDER DRY AND WET CONDITIONS. THE RUNWAY TEXTURE ASPECTS, I.E., GROOVING AND POROUS SURFACES AS TESTED AND REPORTED BY NASA, ARE BEING CONSIDERED FOR APPLICATION IN FORTHCOMING AIRPORT CERTIFICATION RULES.
