147.A.100 requires the training organisation to have classrooms, workshops, and practical training facilities that are adequate for the scope of training courses offered, including appropriate environmental conditions.
What it means in practice
The organisation must provide classrooms sized appropriately for the number of students on each course, with adequate lighting, ventilation, heating, and noise control to support effective learning. For practical training, workshops must be equipped and arranged so that students can carry out the practical elements specified in the training course syllabus. Where aircraft access is required for training, suitable arrangements must be in place.
Examination rooms must be separate from training areas and must provide conditions that allow students to complete examinations without disturbance or the possibility of copying. The facilities must also include adequate office and administrative space for instructors and support staff.
Key requirements
Classrooms must accommodate the maximum number of students without overcrowding. Practical training workshops must contain representative aircraft components, tooling, and equipment relevant to the approved courses. Examination rooms must provide a controlled, supervised environment. All facilities must be maintained in a condition that supports their intended purpose.
Regulation (EU) 2023/989 tightened the facility rules in 147.A.100: accommodation for theoretical training and for knowledge examinations must be fully enclosed and separate from other facilities, with adequate secure storage; under 147.A.100(f), the number of students undergoing training must not exceed 15 per instructor or per assessor in any training class; and under 147.A.100(j), where elements of training are delivered by distance learning, the organisation must ensure students are briefed on, and use, a suitable learning environment.
Common compliance gaps
A frequent finding is classrooms that are too small for the number of students enrolled, or practical workshops that lack sufficient equipment for all students to gain hands-on experience. Another common gap is examination rooms that are not adequately separated from training areas, creating the risk of disturbance or compromise of exam integrity.
