Safety Recommendation A-85-004
Details
Synopsis: ON DECEMBER 6, 1984, A PROVINCETOWN-BOSTON AIRLINES, INC., EMBRAER BANDEIRANTE (EMB-110), N96PB, OPERATING AS FLIGHT 1039, CRASHED SHORTLY AFTER TAKEOFF FROM THE JACKSONVILLE INTERNATIONAL AIRPORT, JACKSONVILLE, FLORIDA. ALL 13 PERSONS ON BOARD WERE KILLED, AND THE AIRPLANE WAS DESTROYED. THE NATIONAL TRANSPORTATION SAFETY BOARD'S CONTINUING INVESTIGATION HAS DISCLOSED THAT THE AIRPLANE'S ELEVATORS AND HORIZONTAL STABILIZER SEPARATED IN FLIGHT, RENDERING THE AIRPLANE UNCONTROLLABLE. EVIDENCE TO DATE INDICATES THAT THE HORIZONTAL STABILIZER SEPARATED FROM THE FUSELAGE AT BULKHEAD 33 ALONG THE TOP RIGHTHAND CORNER OF THE STABILIZER ATTACHMENT FITTING. THIS AREA OF THE BULKHEAD IS SUPPORTED BY C-SHAPED, P/N 4A-1411-08, AND U-SHAPED, P/N 4A-1411-07-17, CHANNELS WHICH ARE RIVETED TOGETHER. THE FUNCTION OF THESE CHANNELS APPEARS TO BE TO TRANSFER THE AFT AND DOWNWARD LOADS ON THE FORWARD ATTACHMENT POINTS OF THE STABILIZER TO THE MONOCOQUE STRUCTURE THROUGH LONGERONS AND THE OUTER FUSELAGE SKIN.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: NOTIFY APPROPRIATE FOREIGN CIVIL AVIATION AUTHORITIES AND/OR FOREIGN OPERATORS OF EMB-110P1 AND -110P2 MODEL AIRPLANES OF THE CIRCUMSTANCES OF THE PROVINCETOWN-BOSTON AIRLINES ACCIDENT OF DECEMBER 6, 1984, AND OF THE ACTIONS RECOMMENDED TO U.S. OPERATORS.

From: FAA

Response:

From: NTSB
To: FAA
Date: 6/24/1986
Response: Safety Recommendation A-85-4 also was classified as "Closed--Acceptable Alternate Action," based on the FAA's action of telephoning the complete text of the Safety Board's recommendation to the CTA as an alternate to a direct notification to foreign civil aviation authorities.

From: FAA
To: NTSB
Date: 1/11/1985
Response: FAA LTR: THE FAA FIRST ADVISED THE CTA OF THE BOARD'S RECOMMENDATIONS BY TELEPHONE ON JANUARY 9 AND PROVIDED THEM WITH A COMPLETE TEXT OF RECOMMENDATIONS A-85-1 THROUGH -4 AND THE PREAMBLE MATERIAL BY TELEGRAM THAT SAME DAY. SINCE FAA HAS NO KNOWLEDGE OF THE FOREIGN COUNTRIES WHERE EMBRAER MODELS EMB-110P1 AND -110P2 ARE OPERATED, NOR OF THE FOREIGN OPERATORS OF THESE AIRCRAFT, IT IS NOT POSSIBLE FOR USE TO PROVIDE THIS INFORMATION. FURTHERMORE, UNDER THE INTERNATIONAL CIVIL AVIATION ORGANIZATION, ANNEX 8, PART II, PARAGRAPH 4.2, IT WOULD BE MORE APPROPRIATE FOR THE CTA TO DISSIMINATE THIS INFORMATION TO FOREIGN AIRWORTHINESS AUTHORITIES. AS YOU WILL SEE IN OUR MESSAGE TO THE CTA, WE SO ADVISED THEM. COPIES OF OUR TELEGRAPHIC TRANSMITTAL OF THE AD T85-01-51 TO THE CTA ARE ENCLOSED.
