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

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

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

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.
