Safety Recommendation A-98-095
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: Require the operators of all turbine-engine driven airplanes (including the EMB-120) to incorporate the manufacturer's minimum maneuvering airspeeds for various airplane configurations and phases and conditions of flight in their operating manuals and pilot training programs in a clear and concise manner, with emphasis on maintaining minimum safe airspeeds while operating in icing conditions.

Safety Recommendation History
From: NTSB
To: FAA
Date: 9/15/2003
Response: The Safety Board notes that the FAA issued Notice N8400.39, "Minimum Maneuvering Airspeeds, and Flight in Icing Conditions," on January 16, 2003. This notice addresses the importance of incorporating manufacturers' minimum maneuvering airspeeds for various airplane configurations and phases and conditions of flight in operating manuals and training programs of air carrier pilots, with an added emphasis on flight in icing conditions. Because the notice emphasizes our recommendation but does not require it, Safety Recommendation A-98-95 is classified "Closed--Acceptable Alternate Action."

From: FAA
To: NTSB
Date: 6/3/2003
Response: Letter Mail Controlled 6/11/2003 3:49:27 PM MC# 2030281 On 1/6/03 the FAA issued Notice N8400.39, Minimum Maneuvering Airspeeds, and Flight in Icing Conditions. This was direction to the principle operations inspectors to insure that these air speed be strongly encouraged to be incorporated into operating manuals and training programs. Advisory Circular 91-74, Pilot Guide: Flight in Icing Conditions, dated 12/12/02, was also included and mentioned in the Notice.

From: FAA
To: NTSB
Date: 2/11/2003
Response: "FAA Staff advised via telephone that the NPRM package with changes to 14 CFR subparts N and O is in internal FAA coordination at this time. The document is 1000 pages and they expect to have it submitted to OST in May 2003."

From: NTSB
To: FAA
Date: 4/11/2000
Response: IN REGARD TO A-98-95, ALTHOUGH HBAT 99-07, HBAW 99-07, AND HBGA 9910, CLARIFY THAT OPERATORS AND POI'S MUST ENSURE THAT ALL OPERATIONAL MANUALS AND PROCEDURES USED ARE CORRECT AND UP-TO-DATE, AND THE BOARD BELIEVES THAT MINIMUM MANEUVERING AIRSPEEDS ARE PART OF THE OPERATIONAL PROCEDURES FOR ANY AIRCRAFT, THE SAFETY BOARD IS DISSAPPOINTED THAT THE BULLETIN DOES NOT SPECIFICALLY MENTION MINIMUM MANEUVERING AIRSPEEDS. ADEQUATELY ADDRESSING THIS TOPIC IS THE SOLE POINT OF A-98-95 AND WAS A SIGNIFICANT FACTOR IN THE ACCIDENT THAT PROMPTED THE RECOMMENDATION. THE RECOMMENDATION ALSO ASKED THAT EMPHASIS BE GIVEN TO THE IMPORTANCE OF MAINTAINING MINIMUM MANEUVERING AIRSPEEDS IN ICING CONDITIONS; HOWEVER, THE BULLETIN DOES NOT MENTION ICING CONDITIONS. PENDING REVISIONS TO THE BULLETIN OR THE ISSUANCE OF A SEPARATE DOCUMENT DISCUSSING MANUFACTURERS' MINIMUM MANEUVERING AIRSPEEDS FOR VARIOUS AIRPLANE CONFIGURATIONS AND PHASES AND CONDITIONS OF FLIGHT, WITH EMPHASIS ON MAINTAINING MINIMUM SAFE AIRSPEEDS WHILE OPERATING IN ICING CONDITIONS, A-98-95 IS CLASSIFIED "OPEN--UNACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 9/16/1999
Response: Letter Mail Controlled 9/22/99 9:22:50 AM MC# 991064 THE FAA AGREES WITH THE INTENT OF THIS SAFETY RECOMMENDATION AND ON 5/28/99, ISSUED JOINT FLIGHT STANDARDS HANDBOOK BULLETIN FOR AIR TRANSPORTATION (HBAT), AIRWORTHINESS (HBAW), AND GENERAL AVIATION (HBGA), FLIGHT STANDARDS POLICY - COMPANY OPERATING MANUALS AND COMPANY TRAINING PROGRAM REVISIONS FOR COMPLIANCE. THE BULLETIN CLARIFIES THE OPERATIONAL INTENT CONCERNING CURRENT MANUAL REVISIONS AND CURRENT TRAINING PROGRAMS. THE BULLETIN ALSO REEMPHASIZES THAT EACH OPERATOR IS REQUIRED TO KEEP ITS AFM, RFM, COMPANY FLIGHT MANUAL, AND TRAINING PROGRAMS CURRENT ON AN ONGOING BASIS. EACH OPERATOR MUST UPDATE AFFECTED MANUALS AND TRAINING PROGRAMS TO INCORPORATE FAA-APPROVED MATERIAL PERTAINING TO OPERATING LIMITATIONS, OPERATING PROCEDURES, PERFORMANCE INFORMATION, LOADING INFORMATION, AND OTHER INFORMATION NECESSARY FOR SAFE OPERATIONS. I HAVE ENCLOSED A COPY OF THE BULLETIN FOR THE BOARD'S INFORMATION. I CONSIDER THE FAA'S ACTION TO BE COMPLETED, AND I PLAN NO FURTHER ACTION.

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.
