Synopsis: ABOUT 0019, SUNDAY FEBRUARY 17, 1991, RYAN INTERNATIONAL AIRLINES FLIGHT 590 (RYAN 590), A DC-9-15, CRASHED WHILE TAKING OFF FROM CLEVELAND-HOPKINS INTERNATIONAL AIRPORT (CLE). THE FLIGHTCREW CONSISTED OF TWO PILOTS. THERE WERE NO OTHER CREWMEMBERS OR PASSENGERS ON THE FLIGHT, WHICH WAS CONTRACTED TO CARRY MAIL FOR THE U.S. POSTAL SERVICE. BOTH PILOTS WERE FATALLY INJURED, AND THE AIRPLANE WAS DESTROYED AS A RESULT OF THE ACCIDENT. BETWEEN 1968 AND 1987, THERE WERE FOUR ACCIDENTS INVOLVING DC-9 SERIES 10 AIRPLANES IN WHICH THERE WAS A LOSS OF CONTROL SHORTLY AFTER TAKEOFF. IN ALL CASES, THE INVESTIGATION SHOWED THAT THE AIRPLANES ACCELERATED NORMALLY AND REACHED AIRSPEEDS AT WHICH THEY SHOULD HAVE BEEN CAPABLE OF ESTABLISHING AND SUSTAINING A SAFE CLIMB. INSTEAD, ALL WERE OBSERVED TO ENTER STEEP ROLL ATTITUDES AND DESCEND TO THE GROUND. ALSO, IN ALL OF THESE ACCIDENTS, WITNESSES REPORTED, AND THE SOUNDS ON THE COCKPIT VOICE RECORDERS (CVRS) CONFIRMED, THAT ENGINE COMPRESSOR SURGES OCCURRED AS THE AIRPLANES DESCENDED.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE AIR CARRIER OPERATORS, WHEN ACQUIRING A NEW MODEL AIRRAFT, TO FORMALLY REQUEST FROM THE MANUFACTURER ALL PERTINENT INFORMATION PREVIOUSLY DISSEMINATED REGARDING THE OPERATION OF THE PARTICULAR AIRCRAFT TYPE.
