Appendix II
Basic knowledge examination standard
1 General
1.1 All basic examinations must be carried out using the multi-choice question format
and essay questions as specified below. The incorrect alternatives must seem equally
plausible to anyone ignorant of the subject. All of the alternatives should be clearly
related to the question and of similar vocabulary, grammatical construction and
length. In numerical questions, the incorrect answers should correspond to
procedural errors such as corrections applied in the wrong sense or incorrect unit
conversions: they must not be mere random numbers.
1.2 Each multi-choice question must have 3 alternative answers of which only 1 must be
the correct answer and the candidate must be allowed a time per module which is
based upon a nominal average of 75 seconds per question.
1.3 Each essay question requires the preparation of a written answer and the candidate
must be allowed 20 minutes to answer each such question.
1.4 Suitable essay questions must be drafted and evaluated using the knowledge syllabus
in Appendix I, Modules 7, 9 and 10.
1.5 Each question will have a model answer drafted for it, which will also include any
known alternative answers that may be relevant for other subdivisions.
1.6 The model answer will also be broken down into a list of important points known as
Key Points.
1.7 The pass mark for each module, or sub-module, multi-choice part of the examination
is 75%.
1.8 The pass mark for each essay question is 75% in that the candidate’s answer must
contain 75% of the required key points addressed by the question and no significant
error related to any required key point.
1.9 If either the multi-choice part or the essay part is failed, then it is only necessary to
retake the multi-choice or essay part, as appropriate.
1.10 Penalty marking systems must not be used to determine whether a candidate has
passed.
1.11 A failed module examination may not be retaken by a candidate for at least 90 days
after the date of the examination. However, if the candidate undergoes a course of
retraining, tailored to the failed subjects of a module, conducted by an MTO, the
examination may be retaken after 30 days.
1.12 The period mentioned in paragraph 66.A.25 (ea) for the passing of a module
examination does not apply if the examination has been passed by a candidate in
relation to another category, or subcategory, of aircraft engineer licence held by
the candidate.
1.13 After a set of 3 failed attempts by a candidate of a module examination, the
candidate must wait 1 year after the date of the third failed attempt before
attempting the examination again. The candidate must give written notice to the
body (an MTO or CASA) the candidate applies to to sit the examination again,
after the third failed attempt, of the following:
(a) the number, and dates, of attempts by the candidate of the examination;
(b) for each examination attempt notified by the candidate — details of the
body (an MTO or CASA) that conducted the examination.
98
Note The MTO or CASA, as applicable, is responsible for verifying the number, and dates, of
attempts by the candidate of the examination.

Part 2 — Type training theoretical elements
Although aircraft type training includes both theoretical and practical elements, courses can
be approved for the theoretical element, the practical element or for a combination of both.
Theoretical element
1 Objective:
On completion of a theoretical training course, the student must be able to
demonstrate, to the levels identified in the Appendix III syllabus, the detailed
theoretical knowledge of the aircraft’s applicable systems, structure, operations,
maintenance, repair, and troubleshooting according to approved maintenance data.
The student must be able to demonstrate the use of manuals and approved
procedures, including the knowledge of relevant inspections and limitations.
2 Level of training:
Training levels are those levels defined in Part 1 above. After the first type course
for Category C certifying staff, all subsequent courses need only be to Level 1.
During a Level 3 theoretical training, Level 1 and Level 2 training material may be
used to teach the full scope of the chapter if required. However, during the training
the majority of the course material and training time must be at the higher level.
3 Duration:
The theoretical training minimum tuition hours are contained in the following table:
Category Hours
Aeroplanes with a maximum B1.1 150
take-off mass above 30 000 kg
B1.2 120
B2 100

30 000 kg and above 5 700 kg
B2 100
C 25
Large helicopters B1.3 120
B2 100
C 25
(a) For the purpose of the table above, tuition hour means 60 minutes of teaching
and excludes any breaks, examination, revision, preparation and aircraft visits.
(b) Hours prescribed in the table above apply only to theoretical courses for
complete aircraft/engine combinations according to the type rating as defined by
CASA.
Minimum participation time is at least 90% of the tuition hours of the theoretical
training course. Additional training may be given by the training organisation in
order to meet the minimum participation time. The number of tuition hours per day
for the theoretical training must not exceed 8 hours, which must be performed during
regular office hours; in exceptional cases, deviation from this standard may be
envisaged when justified. This maximum number of hours is also applicable for the
combination of theoretical and practical training, when they are performed at the
same time.
4 Justification of course duration:
When applying for approval of a Part 147 course, or a course to be approved directly
by CASA, the proposed hour duration must be justified and shown to cover the full
syllabus by a training needs analysis based on:
(a) the design of the aircraft type, its maintenance needs and the types of operation;
and
(b) detailed analysis of applicable chapters – see contents table below; and
(c) detailed competency analysis showing that the objectives as stated in
paragraph 2.1 (a) above are fully met; and
(d) information based on approved type design, if necessary.
Tuition hours of differences courses, and other training course combinations, such as
combined B1/B2 courses, must be justified to CASA by the training needs analysis
as described above.
5 Content:
As a minimum, the elements in the syllabus below, that are specific to the aircraft
type, must be covered. Additional elements introduced due to type variations,
technological changes etc. must also be included. The training syllabus should be
focused on mechanical, powerplant, structural and electrical aspects for B1
personnel, and electrical and avionic aspects for B2.

(b) correctly use all technical literature and documentation for the aircraft;
(c) correctly use specialist and special tooling and test equipment, perform removal
and replacement of components and modules unique to type, including any
on-wing maintenance activity.
Part 4
A Theory element — examination standard
Where aircraft type training is required, the examination must be written and comply
with the following:
(a) Format of the examination is of the multiple-choice type. Each multi-choice
question must have 3 alternative answers of which only 1 must be the correct
answer. The time for answering is based upon a nominal average of 90 seconds
per question.
(b) Alternative answers must seem equally possible to anyone with no knowledge
of the subject. All of the alternatives should be clearly related to the question
and of similar vocabulary, grammatical construction and length.
(c) In numerical questions, the incorrect answers must correspond to procedural
errors such as the use of incorrect sense (+ versus -) or incorrect measurement
units: they must not be mere random numbers.
(d) Subject to paragraph (j), the level of each question should be the one defined in
Part 2 “type training standard”.
(e) The examination must be of the closed book type. No reference material is
permitted. An exception will be made for the case of examining a B1 or B2
candidate’s ability to interpret technical documents.
(f) The number of questions must be at least 1 question per hour of instruction,
with a minimum of 1 question per chapter. CASA will assess number and level
of questions on a sampling basis when approving the course. The number of
questions for each level must be consistent with the effective training hours
spent teaching at that level.
(g) The minimum examination pass mark is 75%. When the type training
examination is split into several examinations, each examination must be passed
with at least a 75% pass mark. For it to be possible to achieve exactly a 75%
pass mark, the number of questions in the examination must be a multiple of 4.
(h) Penalty marking is not to be used to determine whether a candidate has passed.
(i) End of module phase examinations cannot be used as part of the final
examination unless they contain the correct number and level of questions
required.
(j) It is accepted that during a Level 3 examination, Level 1 and Level 2 questions
may be used to examine the full scope of the course material. However, during
the examination it is not acceptable to use more than 25% of questions at any
lower level such that the intention of the higher examination level is reduced.
Note Penalty marking means deducting marks for an incorrect answer.

Note 1 An AMO in accordance with section 145.A.37 of the Part 145 MOS, or a COA holder in accordance
with Civil Aviation Order 104.0 (Certificates of approval — application, grant and conditions) (a CAR 30
organisation), may deliver excluded system training and assessment for the excluded systems set out in this
Appendix — see paragraph 66.A.45 (h).
Note 2 See regulation 66.110 of CASR and subsection 66.A.70 (c) of this MOS for requirements for removal
of these exclusions on type ratings.
Eligibility for removal of an exclusion from an aircraft type rating is only established by first
having the affiliated exclusion removed from the category (e.g. a B1.1 with a propeller
exclusion would first need to gain the appropriate category training from an MTO before an
AMO could provide rating exclusion removal training for the propeller system).
