CASA PNG Rules and Advisory Publications
What this domain tests
This domain examines how well you navigate the PNG Civil Aviation Rules and the advisory material that supports them. The rules are organised by numbered parts: Part 1 definitions, Part 21 certification, Part 43 maintenance, Part 66 licensing, Part 91 general operations, Parts 121 and 135 air operations, Part 145 maintenance organisations, Part 92 dangerous goods and Part 140 aviation security are common examples. You should know what a part does, where to find a definition, and how an amendment changes an existing approval.
Rules versus guidance
- A rule creates a legal requirement; breach can lead to enforcement action.
- An advisory circular describes an acceptable means of compliance or explains policy; it is not itself a rule.
- An airworthiness directive is mandatory and may require action within a stated time.
- A notice or direction may impose temporary requirements; read its authority and expiry.
- Foreign regulations do not apply in PNG merely because a PNG rule is similar; use the PNG text.
Worked example
An AME finds an advisory circular recommending a particular non-destructive testing method for a repair. The approved repair scheme and Part 43 require a different inspection interval. The circular is useful guidance on technique but cannot shorten or extend the approved interval. The AME follows the repair scheme, records the inspection and raises a query with the authority if the documents conflict.
Traps that cost marks
Treating an advisory circular as a rule; assuming a foreign FAA or EASA approval automatically satisfies PNG requirements; missing a recent rule amendment; and overlooking that a mandatory airworthiness directive can be more demanding than the operator's maintenance programme.
