AMT Engine Inspection Study Guide

Flashcards covering key concepts from the AMT Engine Inspection Study Guide.

What are welds in exhaust manifolds particularly susceptible to?

Cracks, distortion, and erosion failures.

What tool is used to detect deteriorated exhaust wall thickness caused by erosion?

A metal probe.

What can a spark plug's condition indicate?

A healthy engine, or a potential problem.

What do cracked cylinder fins primarily affect?

The cooling effectiveness of the cylinder.

What does red-colored oil leaking from a constant-speed propeller hub generally indicate?

A crack.

What may happen if sheaves are not properly balanced?

They may cause many engine components to absorb vibrations, shortening their useful life span.

According to Part 43.15(c)(2), what must a mechanic perform before approving an aircraft for return to service?

A post inspection run-up of each engine.

What should a mechanic obtain before beginning a reciprocating engine inspection?

A checklist and other applicable reference materials to data sheets.

What does Part 43.15(c)(1) require when performing an annual or 100-hour inspection?

The use of a checklist.

What should be verified regarding the ignition switch during a pre-start inspection?

Verified that it is off.

What may discolored paint on a cylinder indicate?

Exposure to extreme temperatures.

Why is a pre-inspection run-up useful?

It is one of the best ways to detect malfunctions in engine and propeller systems and components.

What is a compression test used to determine?

The internal condition and "health" of an engine.

At least what magnification is recommended when inspecting an engine mount for cracks?

At least a 10 power magnifying glass.

What does a cold section inspection of a turbine engine include?

Inspection of the components of a turbine engine's inlet, compressor, or diffuser.

What are compressor blades especially vulnerable to?

Damage and erosion caused by ingestion of sand, ice, and other foreign objects.

What inspection tool is commonly used to inspect a turbine engine hot section without disassembly?

A borescope.

How are stress rupture cracks on turbine blades typically described?

Hairline cracks that appear on the leading and trailing edges of turbine blades at a right angle/perpendicular to the blade's length.

What does "burner can shift" refer to?

Misalignment of combustion liners.

How does Foreign Object Damage (FOD) commonly appear?

Small nicks, dents, and scratches.

What do most turbine engine overspeed inspections focus on?

The engine's rotating elements.

What may cause human-factor-related inspection errors?

Complacency and missed steps, not following regulatory and manufacturer's inspection instructions, and not performing follow-up maintenance.

Which inspection tool provides sharp, color images on a video monitor?

Electronic Imaging System.

Which inspections are considered routine inspections?

Preflight inspections, airworthiness inspection programs, and cold and hot section inspections.

What should occur during lubrication system checks when bridging a magnetic chip detector?

The chip detection warning light should illuminate.
