6 Surveys

 6.1 Each craft should be subject to the surveys specified below:

  • .1 an initial survey before the craft is put into service or before the Wing-in-ground Craft Safety Certificate is issued for the first time;

  • .2 a renewal survey at intervals specified by the Administration but not exceeding 5 years except where 9.5 or 9.10 are applicable;

  • .3 a periodical survey within three months before or after each anniversary date of the Wing-in-ground Craft Safety Certificate; and

  • .4 an additional survey as the occasion arises.

 6.2 The surveys referred to in 6.1 should be carried out as follows:

  • .1 the initial survey should include:

    • .1 an appraisal of the safety assessment and safety management assumptions made as per part C and limitations proposed in relation to loadings, environment, speed and manoeuvrability;

    • .2 an appraisal of the data supporting the safety of the design, obtained, as appropriate, from calculations, tests and trials;

    • .3 a System Safety Assessment (SSA) as required by these Guidelines;

    • .4 an investigation into the adequacy of the various manuals to be supplied with the craft; and

    • .5 a complete inspection of the structure, safety equipment, radio installations and other equipment, fittings, arrangements and materials to ensure that they comply with the provisions of the Guidelines, are in satisfactory condition and are fit for the service for which the craft is intended;

  • .2 the renewal and periodical surveys should commence with an assessment of the continued validity of the safety assessment. These surveys should also include a complete inspection of the structure, including the outside of the craft's bottom and related items, safety equipment, radio installations and other equipment as referred to in 6.2.1 to ensure that they comply with the requirements of the Guidelines, are in satisfactory condition and are fit for the service for which the craft is intended. The inspection of the craft's bottom should be conducted with the craft out of the water under suitable conditions for close-up examination of any damaged or problem areas; and

  • .3 an additional survey, either general or partial according to the circumstances, should be carried out after a repair resulting from investigations prescribed in 8.3, or whenever any important repairs or renewals are made. The survey should be such as to ensure that the necessary repairs or renewals have been effectively carried out, that the material and workmanship of such repairs or renewals are in all respects satisfactory, and that the craft complies in all respects with the provisions of the Guidelines.

 6.3 The periodical surveys referred to in 6.1.3 should be endorsed on the Wing-in-ground Craft Safety Certificate.

 6.4 The inspection and survey of the craft, as provided for in these Guidelines, should be carried out by officers of the Administration. The Administration may, however, entrust the inspections and surveys either to surveyors nominated for the purpose or to organizations recognized by it.

 6.5 An Administration nominating surveyors or recognizing organizations to conduct inspections and surveys as set forth in 6.4 should, as a minimum, empower any nominated surveyor or recognized organization to:

  • .1 require repairs to a craft; and

  • .2 carry out inspections and surveys if requested by the appropriate authorities of a port State.

The Administration should notify the Organization of the specific responsibilities and conditions of the authority delegated to nominated surveyors or recognized organizations.

 6.6 When a nominated surveyor or recognized organization determines that the condition of the craft or its equipment does not correspond substantially with the particulars of the Certificate or is such that the craft is not fit to operate without danger to the craft or persons on board, such surveyor or organization should immediately ensure that corrective action is taken and should, in due course, notify the Administration. If such corrective action is not taken, the Certificate should be withdrawn and the Administration should be notified immediately; and, if the craft is in an area under the jurisdiction of another Government, the appropriate authorities of the port State should be notified immediately. When an officer of the Administration, a nominated surveyor or a recognized organization has notified the appropriate authorities of the port State, the Government of the port State concerned should give such officer, surveyor or organization any necessary assistance to carry out their obligations under this section. When applicable, the Government of the port State concerned should ensure that the craft does not continue to operate until it can do so without danger to the craft or the persons on board.

 6.7 In every case, the Administration should fully guarantee the completeness and efficiency of the inspection and survey and should undertake to ensure the necessary arrangements to satisfy this obligation.
