Engine Exhaust and Reverser Systems
5-10% of the A&P Powerplant test, about 5 to 10 of the 100 questions. The FAA's test standard lists 4 knowledge elements and 5 risk management elements for this area. Here is every one, plus sample questions to try.
What the FAA tests
From the aviation mechanic test standard, FAA-S-ACS-1.
Knowledge: what you must know
- AM.III.L.K1Reciprocating engine exhaust system theory, components, operation, and inspection.
- AM.III.L.K2Turbine engine exhaust system theory, components, operation, and inspection.
- AM.III.L.K3Noise suppression theory, components, and operation (e.g., mufflers, hush kits, augmenter tubes).
- AM.III.L.K4Thrust reverser theory, components, and operation.
Risk management: hazards you must be able to spot and manage
- AM.III.L.R1Maintenance and inspection of exhaust system components.
