Safety Recommendation A-98-088
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: Amend the definition of trace ice contained in FAA order 7110.101, "Flight Services," (and in other FAA documents as applicable) so that it does not indicate that trace icing is not hazardous.

Response: Letter Mail Controlled 03/14/2000 3:45:12 PM MC# 2000388: The Federal Aviation Administration (FAA) agrees with this safety recommendation and has revised the definition of trace ice as follows: Trace: Ice becomes perceptible. Rate of accumulation slightly greater than sublimation. Deicing/anti-icing equipment is not utilized unless encountered for an extended period of time (over 1 hour). The revised definition has been incorporated into Order 7110.10N, Flight Services; the Aeronautical Information Manual; the Pilot/Controller Glossary, which is part of Order 7110.10N; and Order 7110.65, Air Traffic Control. I have enclosed copies of the pertinent pages from these documents for the Board's information. I consider the FAA's action to be completed on this safety recommendation, and I plan no further action.
