| 6 | 98.16.06.01/I | 03-Jun-98 | 14-Jul-98 | REC/98.16.06.01/I/03 | OPERATOR | Until modifications by the fuel pump manufacturer, it is recommended not to use the same type and model of the fule pump involved. |
| 7 | 97.35.12.03/A | 19-Dec-97 | 14-Dec-00 | REC/97.35.12.03/A/01 | MANUFACTURER | It is recommended that the ICAO FLIREC Panel undertake a comprehensive review and analysis of flight data recorders and cockpit voice recorders systems design philosophy be undertaken by aircraft and equipment manufacturers. The purpose of the review and analysis would be to identify and rectify latent factors associated with stoppage of the recorders in flight, and if needed, to propose improvements to ensure recording until time of occurrence. |
| 8 | 97.35.12.03/A | 19-Dec-97 | 14-Dec-00 | REC/97.35.12.03/A/02 | MANUFACTURER | It is recommended that, to facilitate the recovery of flight recorders after impact into water, a review of the flight recorders design philosophy be undertaken by the equipment manufacturers to ensure that the underwater locator beacons (ULB) are fitted to the flight recorders in such a manner that the ULB would not be separated from the recorders in an accident. |
| 9 | 97.35.12.03/A | 19-Dec-97 | 14-Dec-00 | REC/97.35.12.03/A/03 | MANUFACTURER | It is recommended that the ICAO FLIREC Panel recommend aircraft and equipment manufacturers to include recording of actual displays as observed by pilots in particular for CRT type of display panels. |

The purpose of developing the additional training is to enhance pilot awareness on the possibility of unexpected hazardous flight situations. |
| 11 | 97.35.12.03/A | 19-Dec-97 | 14-Dec-00 | REC/97.35.12.03/A/05 | MANUFACTURER | It is recommended that a review of aircraft auto-flight systems be undertaken by aircraft and equipment manufacturers to provide all passenger aircraft with auto flight systems that could prevent an aircraft from flying beyond the high speed limit of its flight envelope. It is also recommended that such auto flight systems limit the rate of descent of the aircraft to a certain value that operationally safe. |
| 12 | 97.35.12.03/A | 19-Dec-97 | 14-Dec-00 | REC/97.35.12.03/A/06 | GENERAL | It is recommended that a regional investigation framework for co-operation in aircraft accident investigations be established to enable fast mobilization of resources and coordination of activities to support those states that do not have the resources and facilities to do investigations on their own. |

| a. Corrosion control program. An additional corrosion protection process immediately after anodization step is strongly recommended (this measure has been applied to the fittings since 1993). The application of an additional coating containing primer, top coat and corrosion inhibiting compound (CIC) is also recommended on particular parts that can potentially be attacked by corrosion. | ||||||
| b. Material selection. It is recommended that Al2024, instead of Al7075, be used for the hinges. | ||||||
| c. Manufacturing process. It is recommended to take into consideration the grain direction relative to the load in the manufacturing of the hinges. | ||||||
