Safety Recommendation History
From: FAA
To: NTSB
Date: 2/4/1971
Response: FAA SHARING THE BOARD'S CONCERN COMMENTED THAT THE TIME TO 100 KNOTS WAS WIDELY USED BY OPERATORS WHEN TURBOJETS WERE FIRST INTRODUCED. IT WAS NOT REQUIRED BY REGULATION AND HAS SINCE BEEN DISCONTINUED AS INEFFECTIVE. THE AIR FORCE, WHO ALSO USED THE TIME OR DISTANCE AGAINST AIRSPEED FOR CHECKING ACCELERATION, HAD ALSO DISCONTINUED ITS USE EXCEPT FOR A VERY LIMITED NUMBER OF AIRCRAFT WHICH HAVE SLOWER ACCELERATION RATES THAN THE TYPE EQUIPMENT BEING USED BY THE AIRLINES. SINCE INERTIAL NAVIGATION SYSTEMS ARE BEING INSTALLED ON AN INCREASING NUMBER OF LARGE AIR CARRIER AIRCRAFT, THEY PLAN TO EXPLORE THE POSSIBILITY OF THE ADDITIONAL USE OF THIS EQUIPMENT TO PROVIDE TAKEOFF PERFORMANCE INFORMATION. THIS SUBJECT WAS DISCUSSED AT THEIR MEETING WITH THE OPERATIONS COMMITTEE OF THE AIR TRANSPORT ASSOCIATION ON 1/19/71. AIR CARRIER REPRESENTATIVES WHO OPERATE AIRCRAFT WITH INERTIAL SYSTEMS AGREED TO EXPLORE THE PROBLEM WITH THEIR TECHNICAL PEOPLE. THE AIR TRANSPORT ASSOCIATION WILL BE ASKED TO PROVIDE RESULTS OF THEIR INVESTIGATION. 10/13/72 LETTER FROM THE SECRETARY, DOT TO THE CHAIRMAN SAYING THAT HE HAS BEEN ASSURED BY THE ADMINISTRATOR OF THE FAA THAT NO KNOWN METHOD OF TIME OR DISTANCE REFERENCE IS AVAILABLE WHICH WILL RESOLVE THE INACCURACIES AND VARIABLES WHICH COME TO PLAY IN THE TAKE-OFF ROLL. BOTH THE ADMINISTRATOR AND ASSISTANT SECRETARY FOR SAFETY AND CONSUMER AFFAIRS WILL REMAIN ALERT TO NEW DEVELOPMENTS IN THIS FIELD. 10/2/73 BOARD EVALUATION. SUPERSEDED BY RECOMMENDATIONS A-72-2, 3 AND 4 ISSUED ON 1/3/72.

From: FAA
To: NTSB
Date: 8/25/1970
Response: After their review and analysis of all available data they conclude that there is room for improvement in the service information related to the maintenance of the fh-1100 and allison 25 engine fuel systems. Allison issued temporary revision number 3-1 to their maintenencemanual on 11 march 1970. The revision provides detailed instructions for cleaning the 60-micron size filter. This instruction is applicable to fairchild-hiller, bell, and hughes aircraft having the allison model 250 engine installed. Fairchild-hiller recommends that the main fuel filter, a dual element of 74-micron size, incorporating a pressure differential switch, be cleaned each 300 hours of operation. Faa have recommended a change to this maintenance instruction reducing the frequency to 100 hours or at any time that element has bypassed fuel. In addition, faa have recommended that when there is evidence that a fuel filter has ruptured or becomes plugged and bypassed fuel, that all filters in the entire systembe checked for contamination. In response to faa's recommendations, fairchild-hiller issued service letter fh-1100-72-1 dated 26 june 1970. This service letter recommends inspection, cleaning, and reinstallation of all fuel filters within 10 hours of operation.
