AMC1 147.A.130(a)Training procedures and quality system

Show the text

This guidance material provides some clarifications for the incorporation of new training methods and training technologies in the procedures for aircraft maintenance training. The classic training method is a teacher lecturing the pupils in a classroom. Commonly the training tools are a blackboard and training manuals. New technologies make it possible to develop new training methods and use other training tools, e.g. multimedia-based training and virtual reality. A combination of several training methods/tools is recommended in order to increase the overall effectiveness of the training. Simulation cannot be eligible as a sole training or assessment tool for basic hand skills such as wiring, welding, drilling, filing, wire locking, riveting, bonding or any other skill where competence may only be achievable by performing a hands-on activity. Three tables are provided to illustrate the possibilities for the use of different training methods and tools: Table 1: Training tools Table 2: Training methods Table 3: Combination of training methods and tools and their use Table 1 lists existing training tools that may be selected for the training.

Table 1: Training tools

Training toolsDescription
1Slideshow presentationA structured presentation of slides.
2ManualsComprehensive and controlled publication of a particular topic.
3Computer (desktop PC, laptop, etc.)An electronic processing device that can hold and display information in various media.
4Mobile devices (such as, but not limited to, tablets, smart phones, etc.)A mobile electronic processing device that can hold and display information in various media.
5VideosElectronic media for broadcasting moving visual images.
6MSTD — Maintenance simulation training deviceA training device that is intended to be used in maintenance training, examination, and/or assessment for a component, system or entire aircraft. The MSTD may consist of hardware and software elements.
7Mock-upA scaled or full-size replica of a component, system or entire aircraft that preserves (i.e. is an exact replica of) the geometrical, operational or functional characteristics of the real component, system or entire aircraft for which maintenance training is delivered with the use of such a replica.
8Virtual realityA computer-generated three-dimensional (3D) environment which can be explored and possibly interacted with.
9MTD — Maintenance training deviceMaintenance training device is any training device other than an MSTD used for maintenance training and/or examination and/or assessment. It may include mock-ups.
10Real aircraftA suitable aircraft whose condition allows teaching a selection of maintenance tasks that are representative of the particular aircraft or of the aircraft category. ‘Suitable’ means an aircraft of the type or licence (sub)category (if the licence (sub)category aircraft is outfitted with the same equipment subject to the particular lesson module(s) and is sufficiently similar so that the lesson objective(s) can be satisfactorily accomplished) for type training, or an aircraft representative of the licence (sub)category for basic training, and excludes ‘virtual aircraft’. ‘Condition’ means that the aircraft is equipped with its main components and that the systems can be activated/operated when this is required by the learning objectives.
11Aircraft componentA suitable aircraft component used to teach specific maintenance tasks off-the-wing. This may include but is not limited to tasks such as borescope inspections, minor repairs, testing, or the assembly/disassembly of sub-components. ‘Suitable’ means that the condition of the component should fit the learning objectives of the tasks and, when appropriate, may feature existing defects or damages.
12Augmented realityAn enhancement (modification, enrichment, alteration or manipulation) of one’s current perception of reality elements of a physical, real-world environment following user’s inputs picked up by sensors transferred to rapid streaming computer images. By contrast, virtual reality replaces the real world with a simulated one.
13Embedded trainingA maintenance training function that is originally integrated into the aircraft component’s design (i.e. a centralised fault display system).
14ClassroomA physical, appropriate location where learning takes place.
15Virtual classroomA simulated, not physical, location where synchronous learning takes place.
16Virtual aircraftA simulated, not physical, aircraft that may be used in theoretical training, practical training, examination or assessment.
Note: Synthetic training devices (STDs) is a generic term used for systems using hardware and/or software, simulating the behaviour of one or more aircraft systems or a complete aircraft, such as maintenance simulation training devices (MSTDs), maintenance training devices (MTDs) and flight simulation training devices (FSTDs).

Table 2 lists existing training methods that may be selected for the training.

Table 2: Training methods

Training methodDescriptionInstructor-centred(1)Student-centred(2)Blended training(3)
Assisted learning (mentoring)Assisted learning or mentorship represents an ongoing, close relationship of dialogue and learning between an experienced /knowledgeable instructor and a less experienced/knowledgeable student in order to develop experience/knowledge of students.XXX
Computer-based training (CBT)CBT is any interactive means of structured training using a computer to deliver a content. (Note: Not to be confused with competency-based training that also uses the acronym ‘CBT’)XXX
DemonstrationA method of teaching by example rather than explanation.XX
Distance learning asynchronousDistance learning reflects training situations in which instructors and students are physically separated. It is asynchronous if the teacher and the students do not interact at the same time.XX
Distance learning synchronousDistance learning reflects training situations in which instructors and students are physically separated. It is synchronous if the teacher and the students interact at the same time (real time).XX
e-learningTraining via a network or electronic means, with or without the support of instructors (e-tutors).XXX
Lecturing (instructor-led/face to face)Practice of face-to-face delivery of training and learning material between an instructor and students, either individuals or groups.XX
Mobile learning (M-learning)Any sort of learning that happens when the student is not at a fixed, predetermined location, using mobile technologies.XXX
Multimedia-based training(4)Any combined use of different training media.XXX
SimulationAny type of training that uses a simulator imitating a real-world process or system.XXX
Web-based training (WBT)Generic term for training or instruction delivered over the internet or an intranet using a web browser.XXX
Note: The purpose of this table is to provide a short definition for each associated training method and to relate each method to the focus of the learning. It is not meant to comprehensively explore and identify the capabilities of each training method herein included. (1) ‘Instructor-centred’ means that the instructor is responsible for teaching the student. (2) ‘Student-centred’ means that the student is responsible for the learning progress. (3) ‘Blended training’ includes different instructional methods and tools, different delivery methods, different scheduling (synchronous/asynchronous) or different levels of guidance. Blended training allows the integration of a range of learning opportunities. (4) ‘Multimedia-based training’ by definition uses various media to achieve its objective, thus, none of the single media listed is per se a complete solution for training.

Table 3 presents the combination of training methods and tools that may be taken into account for theoretical and practical training. The table is intended to support potential delivery methods. Additional training methods and further use of those methods could be acceptable to the competent authority when demonstrated as supporting learning objectives.

AMC 147.A.130(b)Training procedures and quality system

Show the text

1.The independent audit procedure should ensure that all aspects of Part-147 compliance should be checked at least once in every 12 months and may be carried out as one complete single exercise or subdivided over a 12-month period in accordance with a scheduled plan.

2.In a small maintenance training organisation the independent audit function may be contracted to another maintenance training organisation approved under Part-147 or a competent person acceptable to the competent authority. Where the small training organisation chooses to contract the audit function it is conditional on the audit being carried out twice in every 12 month period with one such audit being unannounced.

3.Where the maintenance training organisation is also approved to another Part requiring a quality system, then such quality systems may be combined.

4.When training or examination is carried out under the sub-contract control system:

(i)a pre audit procedure should be established whereby the Part-147 approved maintenance training organisation’ should audit a prospective sub-contractor to determine whether the services of the sub-contractor meet the intent of Part-147.

(ii)a renewal audit of the subcontractor should be performed at least once every 12 months to ensure continuous compliance with the Part-147 standard.

(iii)the sub-contract control procedure should record audits of the sub-contractor and to have a corrective action follow-up plan.

5.The independence of the audit system should be established by always ensuring that audits are carried out by personnel not responsible for the function or procedure being checked.
