About the PNG CASA AME Subject 20 Air Law Exam

Subject 20 (Air Law - Written) is the aviation-law examination in the CASA PNG Aircraft Maintenance Engineer Licence series. CAR 66.57(a)(2) requires an AMEL applicant to have passed written examinations acceptable to the Director, and AC66-2.20 sets the acceptable syllabus for Subject 20. The objective is to establish that the applicant has adequate knowledge of the civil aviation regulatory requirements needed to perform, supervise and certify aircraft maintenance at the level of the various AMEL categories. Note that this page's URL slug uses the phrase 'airworthiness legislation'; the official CASA PNG subject title is Air Law (Written).

Frequently Asked Questions

What is the official name and format of this exam?

CASA PNG calls it Subject 20 (Air Law - Written) in the Aircraft Maintenance Engineer Licence examination series. AC66-2.20 states it is a 2-hour open-book written examination comprised of 50 questions with a pass mark of 75%.

What may I take into the examination room?

AC66-2.20 allows any or all of the listed publications in printed form only. They may be tabbed or indexed, but no handwritten material or study notes are permitted. Check each document against the revision status on the CASA PNG website before you rely on it.

Is there an oral air law examination in Papua New Guinea?

No. CASA PNG's AC66-1 lists AC66-2.20 Subject 20 as Air Law - Written and shows Subject 21 as Reserved. Some other States that use the same numbering do run a separate Subject 21 oral air law examination; PNG does not.

Which rules does Subject 20 cover?

The AC66-2.20 syllabus is organised into fifteen topics covering CAR Parts 1, 12, 20, 21, 39, 43, 47, 66, 91, 119, 135 and 145, plus aeronautical parts and supplies, aircraft maintenance programmes and internal quality assurance.

Are these practice questions the real exam?

No. This is a free English-language multiple-choice study adaptation of the AC66-2.20 syllabus. The official Subject 20 paper is open book and is not necessarily multiple choice, so use this bank to build recall and rule-location skill alongside the actual rules and Advisory Circulars.
