They can be done by a Grade 1 or 2 instructor.
They can be done outside of a school (61.1230), BUT the intent is that a review will include some training to bring someone up to the standard.
61.1230 Obligations of pilot instructors—records of activities conducted independently of Part 141 or 142 operator
(1) A pilot instructor commits an offence if:
(a) the instructor conducts a flight review or a session of flight training for a flight crew endorsement, other than an endorsement on an operational rating; and
(b) the training is not conducted on behalf of a Part 141 or 142 operator; and
(c) a record of the training is not made within 7 days after the session.
(2) A pilot instructor commits an offence if the instructor does not retain a record made under subregulation (1) for at least 7 years after the day the record is made.
Penalty: 50 penalty units.
(3) An offence against this regulation is an offence of strict liability.
The way I have interpreted this - its an offence to conduct a flight review or a session of flight training for a flight crew endorsement, if you're not conducting it on behalf of a 141 or 142 operator, and if you don't make a record of the training within 7 days. Furthermore, it's also and offence if you don't retain the record for 7 years.
However, and this is where I get confused with the wording, does the 'and' mean you have to have done all 3 - (a), (b) and (c) for it to be an offence?
Also, if it's the latter, does this imply you could do flight training, training for type ratings etc independently?
endorsement means a flight crew endorsement,
flight crew endorsement means an endorsement granted under this Part on a flight crew licence.
light crew licence means:
(a) a pilot licence; or
(b) a flight engineer licence; or
(c) a glider pilot licence.
