Iran CAO Part-66 AMT Theory case studies
Iran CAO Part-66 AMT Theory · Put your knowledge to work in context.
The Iran CAO Part-66 Aircraft Maintenance Engineer Licence theory examination is the basic-knowledge assessment a candidate must pass before applying for an aircraft maintenance licence issued by the Civil Aviation Organization of Iran (CAO.IRI). It is aimed at people training to certify maintenance on aeroplanes or helicopters - typically students at an approved Part-147 maintenance training organisation, experienced mechanics seeking their first licence, or licence holders adding a category or type rating. The syllabus follows the familiar Part-66 module structure: mathematics and physics foundations, electrical and electronic fundamentals, digital techniques and electronic instrument systems, materials and hardware, maintenance practices, basic aerodynamics, human factors, aviation legislation, and the large aircraft- or helicopter-specific systems modules. Modules 11 and 12 are alternatives, so you sit the aeroplane stream or the helicopter stream rather than both. The Iran CAO Part-66 AMT Theory case studies are 5 cases and about 2,831 words.
