Details
Synopsis: AT 1521 C.D.T. ON SEPTEMBER 6, 1985, MIDWEST EXPRESS AIR LINES, INC. (MIDWEST EXPRESS), FLIGHT 105, A MCDONNELL DOUGLAS DC-9-14 AIRPLANE, CRASHED INTO AN OPEN FIELD AT THE EDGE OF A WOODED AREA ABOUT 1,680 FEET SOUTHWEST OF THE DEPARTURE END OF RUNWAY 19R SHORTLY AFTER TAKING OFF FROM GENERAL BILLY MITCHELL FIELD, MILWAUKEE, WISCONSIN. THE WEATHER WAS CLEAR WITH VISIBILITY 10 MILES. DURING THE INITIAL CLIMB, ABOUT 450 FEET ABOVE GROUND LEVEL (A.G.L.), THERE WAS A LOUD NOISE AND A LOSS OF POWER ASSOCIATED WITH AN UNCONTAINED FAILURE OF THE 9TH TO 10TH STAGE HIGH PRESSURE COMPRESSOR SPACER OF THE RIGHT ENGINE. FLIGHT 105 CONTINUED TO CLIMB TO ABOUT 700 FEET A.G.L. AND THEN ROLLED TO THE RIGHT UNTIL THE WINGS WERE OBSERVED IN A NEAR VERTICAL, APPROXIMATELY RIGHT 90 DEGREE BANKED TURN. DURING THE ROLL, THE AIRPLANE ENTERED AN ACCELERATED STALL, CONTROL WAS LOST, AND THE AIRPLANE CRASHED. THE AIRCRAFT WAS DESTROYED BY IMPACT FORCES AND POSTCRASH FIRE. THE PILOT, THE FIRST OFFICER, BOTH FLIGHT ATTENDANTS, AND ALL 27 PASSENGERS WERE FATALLY INJURED.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE PRINCIPAL OPERATIONS INSPECTORS OF 14 CFR 121 CERTIFICATE HOLDERS TO HAVE TRAINING AND EXPERIENCE COMMENSURATE WITH THE AIR CARRIER INVOLVED, INCLUDING A COMPARABLE TYPE RATING (E.G., TURBOJET-POWERED TRANSPORT CATEGORY) IN THE CATEGORY AND CLASS OF AIRCRAFT TO BE USED BY THE CERTIFICATE HOLDER.

Response: THE FAA CONCURS WITH THIS RECOMMENDATION. THE FAA IS PRESENTLY ADDRESSING SUCH ISSUES IN DEVELOPING TRAINING COURSES AND A TRAINING DELIVERY SYSTEM TO ENSURE A HIGHLY TRAINED INSPECTOR WORKFORCE. THE FAA HAS DEVELOPED A METHODOLOGY FOR FLIGHT STANDARDS HUMAN RESOURCE MANAGEMENT BY FOCUSING ON THE PRINCIPAL INSPECTOR POSITIONS TO ENSURE CONSISTENCY IN THE PRINCIPAL INSPECTOR WORK FORCE. I BELIEVE THE ONGOING TRAINING UNDER PROJECT SAFE SATISFIES THE INTENT OF THIS RECOMMENDATION AND CONSIDER ACTION COMPLETE ON THIS RECOMMENDATION.
