9 Wing-in-ground Craft Safety Certificate

 9.1 A Certificate called a Wing-in-ground Craft Safety Certificate is issued after completion of an initial or renewal survey to a craft which complies with the provisions of the Guidelines. The Certificate should be issued or endorsed either by the Administration or by any person or organization recognized by it. In every case, that Administration assumes full responsibility for the Certificate.

 9.2 A Contracting Government to the Convention may, at the request of the Administration, cause a craft to be surveyed and, if satisfied that the provisions of the Guidelines are complied with, should issue or authorize the issue of a Certificate to the craft and, where appropriate, endorse or authorize the endorsement of a Certificate for the craft in accordance with the Guidelines. Any Certificate so issued should contain a statement to the effect that it has been issued at the request of the Government of the State the flag of which the craft is entitled to fly, and it should have the same force and receive the same recognition as a Certificate issued under 9.1.

 9.3 The Certificate should be of the model given in annex 1. If the language used is neither English, French nor Spanish, the text should include a translation into one of these languages.

 9.4 The Wing-in-ground Craft Safety Certificate should be issued for a period specified by the Administration which should not exceed 5 years.

 9.5 Notwithstanding the requirements of 9.4, when the renewal survey is completed within three months before the expiry date of the existing Certificate, the new Certificate should be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing Certificate.

 9.6 When the renewal survey is completed after the expiry date of the existing Certificate, the new Certificate should be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing Certificate.

 9.7 When the renewal survey is completed more than 3 months before the expiry date of the existing Certificate, the new Certificate should be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of completion of the renewal survey.

 9.8 If a Certificate is issued for a period of less than 5 years, the Administration may extend the validity of the Certificate beyond the expiry date to the maximum period specified in 9.4, provided that the surveys required when a Certificate is issued for a period of 5 years are carried out.

 9.9 If a renewal survey has been completed and a new Certificate cannot be issued or placed on board the craft before the expiry date of the existing Certificate, the person or organization authorized by the Administration may endorse the existing Certificate and such a Certificate should be accepted as valid for a further period which should not exceed 5 months from the expiry date.

 9.10 If a craft, at the time when a Certificate expires, is not in the place in which it is to be surveyed, the Administration may extend the period of validity of the Certificate but this extension should be granted only for the purpose of allowing the craft to proceed to the place where it is to be surveyed, and then only in cases where it appears proper and reasonable to do so. No Certificate should be extended for a period longer than one month, and a craft to which an extension is granted should not, on its arrival at the place where it is to be surveyed, be entitled by virtue of such extension to leave that place without having a new Certificate. When the renewal survey is completed, the new Certificate should be valid to a date not exceeding 5 years from the date of expiry of the existing Certificate before the extension was granted.

 9.11 In special circumstances, as determined by the Administration, a new Certificate need not be dated from the date of expiry of the existing Certificate as required by 9.6 or 9.10. In these circumstances, the new Certificate should be valid to a date not exceeding 5 years from the date of completion of the renewal survey.

 9.12 If a periodical survey is completed before the period specified in section 6 then:

  • .1 the anniversary date shown on the relevant Certificate should be amended by endorsement to a date which should not be more than 3 months later than the date on which the survey was completed;

  • .2 the subsequent periodical survey required by section 6 should be completed at the intervals prescribed by 6.1.3, using the new anniversary date; and

  • .3 the expiry date may remain unchanged provided one or more periodical surveys are carried out so that the maximum intervals between the surveys prescribed by 6.1.3 are not exceeded.

 9.13 A Certificate issued under 9.1 or 9.2 should cease to be valid in any of the following cases:

  • .1 if the relevant surveys are not completed within the periods specified in 6.1;

  • .2 if the Certificate is not endorsed in accordance with 6.3; or

  • .3 upon transfer of the craft to the flag of another State. A new Certificate should only be issued when the Government issuing the new Certificate is fully satisfied that the craft is in compliance with the requirements of 8.1 and 8.2. In the case of a transfer between Governments that are Contracting Governments to the Convention, if requested within 3 months after the transfer has taken place, the Government of the State whose flag the craft was formerly entitled to fly should, as soon as possible, transmit to the Administration a copy of the Certificate carried by the craft before the transfer and, if available, copies of the relevant survey reports.

9.14 The privileges of the Guidelines may not be claimed in favour of any craft unless it holds a valid Certificate.
