Course Description

Covers reciprocating and turbine engine ignition system theories and overhaul practices, as well as the relationships of the complete ignition system to the powerplant and its operation. Covers proper inspection of the entire engine installation, including exhaust systems, airflow, and cooling systems. Prerequisites: AMT 272. Audit available.

Intended Outcomes

Upon successful completion of this course, students will be able to:

  1. Safely perform aircraft reciprocating and turbine engine ignition system maintenance in accordance with the manufacturer service data, industry practices, and applicable regulations.
  2. Inspect and repair engine exhaust systems, including thrust reverser systems.
  3. Troubleshoot ignition and starting systems and related engine system discrepancies in accordance with the manufacturer service data, industry practices, and applicable regulations.
  4. Identify and repair engine airflow and temperature control malfunctions.

Outcome Assessment Strategies

Evaluations by exams, quizzes and lab work.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
