Course Description

Fundamental theory of aircraft reciprocating engines. Practical experience in overhauling, repair, assembly, testing, and troubleshooting various powerplants. ADVISORY: AMT A150 and AMT A153. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

Demonstrate the ability to overhaul, inspect, repair, install, run, and troubleshoot aircraft reciprocating engines.

Course Objectives

1. Demonstrate and analyze the use of non-destructive testing equipment on reciprocating engine parts.
2. Analyze charts, graphs, and engine data specification sheets.
3. Interpret, calculate and solve valve-timing problems.
4. Explain the principles of the Otto cycle
5. Demonstrate and analyze procedures outlined in the overhaul manual.
6. Identify different types of corrosions visually.
7. Demonstrate the use of precision measuring tools too inspect parts dimensionally.
8. Compare the results of dimensional inspection and verify the results to the Table of Limits in the overhaul manual.
9. Demonstrate the ability to grind valves and valve seats, define proper valve seat margins.
10. Demonstrate the ability to reassemble engine per the overhaul manual verifying acceptable standards and techniques are used.
11. Demonstrate and identify proper torque procedures using the overhaul manual and acceptable standards and techniques.
12. Demonstrate the ability to correctly write a logbook entry per FAA standards.
13. Demonstrate the ability to correctly install an engine in the test cell or aircraft.
14. Demonstrate the ability to test run a reciprocating engine.
15. Analyze results from test running a reciprocating engine.
16. Apply troubleshooting techniques in troubleshooting reciprocating engines.
17. Interpret Type Certificate Data Sheets and Airworthiness Directives information and demonstrate the ability to perform a Conformity Inspections.
18. Gather information and perform a 100-hour/Annual inspection.
19. Evaluate system faults and apply principle in modern engine troubleshooting.
