Safety Recommendation A-98-090
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: With the NASA and other interested aviation organizations, organize and implement an industry-wide training effort to educate manufacturers, operators, and pilots of air carrier and general aviation turbopropeller driven airplanes regarding the hazards to thin, possibly imperceptible, rough ice accumulations, the importance of activating the leading edge deicing boots as soon as the airplane enters icing conditions (for those airplanes in which bridging is not a concern), and the importance of maintaining minimum airspeeds in icing conditions.

Safety Recommendation History
From: NTSB
To: FAA
Date: 1/3/2002
Response: The FAA has previously supplied the Safety Board with copies of the two videos. The production and distribution of this information satisfies the intent of Safety Recommendation A-98-90, which is now classified "Closed--Acceptable Action."

From: FAA
To: NTSB
Date: 8/2/2001
Response: Letter Mail Controlled 08/10/2001 1:11:47 PM MC# 2010634: As a result of the In-Flight Icing Conference, the National Aeronautics and Space Administration (NASA), in cooperation with the Federal Aviation Administration (FAA), produced two videos entitled "Tailplane Icing" and "Icing for Regional and Corporate Pilots." The FAA distributed copies of these videos to all regional and flight standards district offices and has made them available to the public. The video entitled "Tailplane Icing" is an educational video that provides information about ice-contaminated horizontal stabilizers. The video presents a physical description of the tailplane icing problem, symptoms of ice contamination, and suggested recovery procedures. The video entitled "Icing for Regional and Corporate Pilots" is intended for pilots of turboprop aircraft and discusses ice protection systems, how ice accretes on the aircraft, the effects of ice on both the performance degradation and handling qualities, suggested recovery techniques from roll or pitch upset, and the hazards of supercooled liquid droplets. NASA is planning to produce four additional videos dealing with icing effects. On January 12, 2001, the Board expressed concern about how the FAA plans to make this information available and ensure its use in an industrywide training effort to educate manufacturers, operators, and pilots of air carrier and general aviation turbopropeller-driven airplanes. In response, the FAA will distribute the videos as they become available to aircraft manufacturers and all FAA regional and flight standards district offices for use in air carrier flight training programs and for general aviation training through the FAA Aviation Safety Program. However, I want to add that completion of these additional videos is entirely dependent on NASA funding. I believe that the FAA has met the full intent of this safety recommendation, and I consider the FAA's action to be completed.

From: NTSB
To: FAA
Date: 1/12/2001
Response: THE SAFETY BOARD IS PLEASED BY THE ACTIONS THE FAA HAS TAKEN BOTH IN SPONSORING THE CONFERENCE AND IN PRODUCING THE VIDEOS WITH NASA. THE BOARD IS CONCERNED, HOWEVER, ABOUT HOW THE FAA PLANS TO MAKE THIS INFORMATION AVAILABLE AND TO ENSURE ITS USE IN AN INDUSTRYWIDE TRAINING EFFORT TO EDUCATE MANUFACTURERS, OPERATORS, AND PILOTS OF AIR CARRIER AND GENERAL AVIATION TURBOPROPELLER-DRIVEN AIRPLANES. THEREFORE, THE BOARD WOULD LIKE A DESCRIPTION FROM THE FAA OF ITS PLANNED ACTIVITIES TO DISTRIBUTE THIS INFORMATION INDUSTRYWIDE. PENDING RECEIPT OF SUCH A DESCRIPTION AND COMPLETION OF THE TWO REMAINING VIDEOS, A-98-90 REMAINS CLASSIFIED "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 7/7/2000
Response: Letter Mail Controlled 07/12/2000 9:46:00 AM MC# 2000878 THE FAA SPONSORED AN IN-FLIGHT ICING CONFERENCE, FEBRUARY 2-4, 1999. REPRESENTATIVES FROM AIRFRAME MANUFACTURERS, DEICING EQUIPMENT MANUFACTUERS, AVIONICS MANUFACTURERS, PILOT GROUPS, INDUSTRY ASSOCIATIONS, THE SAFETY BOARD, AND THE GENERAL PUBLIC ATTENDED THIS CONFERENCE. THE CONFERENCE INCLUDED WORKING GROUPS IN THE AREAS OF ICE PROTECTION (ICE BRIDGING), TRAINING, DISSEMINATION OF INFORMATION, AUTOPILOT OPERATION, WEATHER INFORMATION IMPROVEMENTS, AND CURRENCY OF AIRPLANE OPERATING INFORMATION IN MANUALS. AS A RESULT OF THE IN-FLIGHT ICING CONFERENCE, THE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION (NASA), IN COOPERATION WITH THE FAA, PRODUCED TWO VIDEOS ENTITLED "TAILPLANE ICING" AND "ICING FOR REGIONAL AND CORPORATE PILOTS." THE FAA HAS DISTRIBUTED COPIES OF THESE VIDEOS TO ALL REGIONAL AND FLIGHT STANDARDS DISTRICT OFFICES AND HAS MADE THEM AVAILABLE TO THE PUBLIC. I HAVE ENCLOSED COPIES OF THE VIDEOS FOR THE BOARD'S INFORMATION. THE VIDEO ENTITLED "TAILPLANE ICING" IS AN EDUCATIONAL VIDEO THAT PROVIDES INFORMATION ABOUT ICE-CONTAMINATED HORIZONTAL STABILIZERS. THE VIDEO PRESENTS A PHYSICAL DESCRIPTION OF THE TAILPLANE ICING PROBLEM, SYMPTOMS OF ICE CONTAMINATION, AND SUGGESTED RECOVERY PROCEDURES. THE VIDEO ENTITLED "ICING FOR REGIONAL AND CORPORATE PILOTS" IS INTENDED FOR PILOTS OF TURBOPROP AIRCRAFT AND DISCUSSES ICE PROTECTION SYSTEMS, HOW ICE ACCRETES ON THE AIRCRAFT, THE EFFECTS OF ICE ON BOTH THE PERFORMANCE DEGRADATION AND HANDLING QUALITIES, SUGGESTED RECOVERY TECHNIQUES FROM ROLL OR PITCH UPSET, AND THE HAZARDS OF SUPERCOOLED LIQUID DROPLETS. THE FAA IS CONTINUING TO WORK WITH NASA ON TWO MORE VIDEOS DEALING WITH OTHER ASPECTS OF ICING.

From: NTSB
To: FAA
Date: 3/9/2000
Response: THE SAFETY BOARD NOTES THAT THE FAA'S IN-FLIGHT ICING CONFERENCE IS A POSITIVE FIRST STEP IN ADDRESSING THE ISSUES OUTLINED IN A-98-90. HOWEVER, THE BOARD REMAINS CONCERNED THAT THE SERIOUSNESS OF PROBLEMS RELATING TO ICING, ESPECIALLY IN THE TURBOPROPELLER AIRCRAFT, HAS NOT BEEN ADEQUATELY ADDRESSED. THESE CONCERNS ARE REFLECTED IN THE ROSELAWN, INDIANA, ACCIDENT AND, MORE RECENTLY, THE MONROE, MICHIGAN, ACCIDENT. PENDING FURTHER INFORMATION FROM THE FAA, A-98-90 IS CLASSIFIED "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 2/26/1999
Response: THE FAA SPONSORED AN IN-FLIGHT ICING CONFERENCE FEBRUARY 2-4, 1999. REPRESENTATIVES FROM AIRFRAME MANUFACTURERS, DEICING EQUIPMENT MANUFACTURERS, AVIONICS MANUFACTURERS, PILOT GROUPS, INDUSTRY ASSOCIATIONS, THE SAFETY BOARD, AND THE INTERESTED PUBLIC ATTENDED THIS CONFERENCE. THE CONFERENCE INCLUDED WORKING GROUPS IN THE AREAS OF ICE PROTECTION (I.E., ICE BRIDGING), TRAINING, DISSEMINATION OF INFORMATION, AUTOPILOT OPERATION, WEATHER INFORMATION IMPROVEMENTS, AND MANUALS AND CURRENCY OF AIRPLANE OPERATING INFORMATION. THE PRODUCTS RESULTING FROM THIS CONFERENCE WILL BE USED FOR POSSIBLE CHANGES TO PILOT INFORMATION, TRAINING, AND ICING REGULATIONS.
