Civil Aviation Regulations 1988

Unless sooner suspended or cancelled, an aircraft welding authority remains in force:

for the period specified in it; or

if it has been renewed—until the end of the last period of renewal.

If an aircraft welding authority is cancelled, its holder must return it to CASA within 7 days after the cancellation.

An offence against subregulation (2) is an offence of strict liability.

For strict liability, see section 6.1 of the Criminal Code.

It is a defence to a prosecution under subregulation (2) if the defendant returned the aircraft welding authority to CASA as soon as practicable.

A defendant bears an evidential burden in relation to the matter in subregulation (4) (see subsection 13.3(3) of the Criminal Code).
