1.0 General

 This section outlines the requirements for the storage and transfer of Jet A1 fuel. When developing fuelling arrangements, consideration should be given to the type of fuel on which the helicopter to be operated is run. In addition, all facilities for the storage and handling of aviation fuels on board should be grade identified using the appropriate American Petroleum Industry (API) markings for the grade of fuel used. Aviation fuel facilities should also be fully segregated from any other fuel system.

  1.1 Helicopter fueling facilities on board should be in accordance with requirements for helicopter refuelling and hangar facilities in SOLAS II-2. In addition, the requirements outlined in this section of Annex 6 of the Code should be complied with in full unless a safety case is made to, and approved by, the Administration, based on an alternative arrangement according to Classification Society Rules or guidance from the Aviation or Petro-Chemical industries.

  1.2 Refuelling and defuelling operational considerations should be agreed with the helicopter pilot / operator and Aviation Inspection Body.

  1.3 The following plans and particulars are to be submitted to the Aviation Inspection Body and Classification Society for approval:

• .1 Description of fuel with statement of minimum flash point (closed cup test);

• .2 Arrangement of fuel storage and piping;

• .3 Arrangements for drainage, ventilation and sounding of spaces adjacent to storage tanks;

• .4 Details and approval certification of pumping units;

• .5 Structural fire protection arrangements of all spaces to contain aviation fuel;

• .6 Fire detection and extinguishing arrangements;

• .7 ventilation arrangements.

  1.4 When developing operational procedures for the movement of aviation fuel onboard, the restricted use of radio frequency equipment including portable phones with regard to transmission sparks should be considered.
