(c)   he or she has passed such examinations in relation to the authority as are required or approved for the purpose.

       1.2     An applicant for the issue of an authority is taken to meet the requirements of subparagraph 1.1 (a) if the applicant:

(a)   has completed a tertiary qualification in a relevant engineering discipline; and

(b)   is eligible for Graduate Membership of Engineers Australia in the Professional Engineer occupational category.

2          Application for authority

       2.1     Application for the issue or extension of an aircraft weight control authority must be made to CASA on Form 377.

3          Examination

       3.1     An applicant will be examined in accordance with the syllabus specified in Appendix I of this Order.

       3.2     A candidate must achieve a minimum mark of 75% to pass the examination, except that where a candidate fails to satisfactorily answer particular questions specified in the question paper, the candidate will be failed irrespective of the total marks achieved.

       5.1     An aircraft weight control authority will be issued to an applicant who has complied with the requirements of this Order.

       5.2     The Director may issue an authority endorsed with such limitations as he considers necessary.

6          Period of validity

       6.1     An aircraft weight control authority is valid for a period of 2 years.

7          Renewal of authority

       7.1     Application for the renewal of an aircraft weight control authority must be made on Form 359, and an authority issued without further examination, provided the holder produces acceptable evidence that he or she has maintained proficiency and familiarity with the methods of aircraft weight control applicable to the authority held.
