Safety Recommendation A-98-099
Details
Synopsis: On January 9, 1997, an Empresa Brasileira de Aeronautica, S/A (Embraer) EMB-120RT, operated by COMAIR Airlines, Inc., crashed during a rapid descent after an uncommanded roll excursion near Monroe, Michigan. The flight was a scheduled, domestic passenger flight from the Cincinnati/Northern Kentucky International Airport, Covington, Kentucky, to Detroit Metropolitan/Wayne County Airport, Detroit, Michigan. The flight departed Covington with 2 flightcrew, 1 flight attendant, and 26 passengers on board. There were no survivors. The airplane was destroyed by ground impact forces and a postaccident fire. IMC prevailed at the time of the accident, and the flight was operating on an IFR flight plan.The probable cause of this accident was the FAA's failure to establish adequate aircraft certification standardds for flight in icing conditions.
Recommendation: TO THE FEDERAL AVIATION ADMINISTRATION: Expedite the research, development, and implementation of revision to the icing certification testing regulations to ensure that airplanes are adequately tested for the conditions in which they are certificated to operate; the research should include identification (and incorporation into icing certification requirements) of realistic ice shapes and their effects and criticality.

Safety Recommendation History
From: NTSB
To: FAA
Date: 3/9/2000
Response: THE SAFETY BOARD AGREES THAT THE INTENT OF A-98-99 CAN BE MET THROUGH ACCEPTABLE ACTION IN RESPONSE TO A-98-92, -94, AND -96. THEREFORE, A-98-99 IS CLASSIFIED "CLOSED--RECONSIDERED."

From: FAA
To: NTSB
Date: 2/26/1999
Response: THERE ARE TWO ISSUES OUTLINED IN THIS RECOMMENDATION THAT THE FAA BELIEVES ARE BEING ADDRESSED IN COMPANION RECOMMENDATIONS A-92, -94, AND -96. THE FIRST ISSUE IN THIS RECOMMENDATION IS TO REVISE ICING CERTIFICATION TESTING REGULATIONS TO ENSURE AIRPLANES ARE ADEQUATELY TESTED FOR THE CONDITIONS IN WHICH THEY ARE CERTIFIED FOR OPERATION. THE ARAC FLIGHT TEST HARMONIZATION WORKING GROUP ACTIVITIES OUTLINED IN RESPONSE TO A-98-94 AND -96 ADEQUATELY ADDRESS THIS PORTION OF THE RECOMMENDATION. THE SECOND ISSUE ADDRESSES RESEARCH ON THE IDENTIFICATION OF REALISTIC ICE SHAPES AND THEIR EFFECTS AND CRITICALITY, AND INCORPORATION OF THESE SHAPES INTO ICING CERTIFICATION REQUIEMENTS. WE BELIEVE THAT THIS ISSUE IS ALREADY BEING ADDRESSED IN RESPONSE TO A-98-92. CONSEQUENTLY, I ASK THAT THE BOARD CLASSIFY THIS RECOMMENDATION IN A "CLOSED ACCEPTABLE" STATUS. I WILL CONTINUE TO KEEP THE BOARD INFORMED OF ITS ACTION IN RESPONSE TO A-98-94, -96, AND -92.

From: NTSB
To: FAA
Date:
Response: At the 1997 Board meeting addressing the NTSB’s Most Wanted List of Transportation Safety Improvements (MWL), the Board voted to place Safety Recommendations A-96-54 through A-96-56, A-96-62, and A-96-69 on the MWL under the issue category “Airframe Structural Icing.” The Board voted to add Safety Recommendations A-98-92, A-98-94, A-98-95, A-98-99, A-98-100, A-07-14 at later dates. Safety Recommendation A-07-16 was added to the MWL upon its adaptation because it supersedes Safety Recommendation A-98-100.
