Engine inspections 3

Question Answer
What inspections must be performed following a turbine engine overspeed? Refer to the engine manufacturer’s maintenance manual for the required procedures.
What inspections must be performed on a turbine engine if the exhaust gas temperature exceeds limitations? A hot section inspection.

What is the hot section of a turbine engine?

Section I: The Hot Section

As the air leaves the high-pressure compressor and enters the combustor, it mixes with fuel and is burned. As the gas is combusted and expands, some gas passes through the exhaust and some is rerouted to the engine’s turbine (a set of fans that rotate compressor blades).

What should you use to inspect a turbine disk?

Inspect the combustion chambers and covers for cracks by using visible dye or fluorescent penetrant inspection method. Any cracks, nicks, or dents are usually cause for rejecting the component.

What is a hot section inspection?

A hot section inspection (HSI) involves examining the condition of a number of key engine parts, including the turbine blades, the combustion chamber, the stators, the vane rings, the compressor turbine disk and the shroud segments. A hot section inspection is performed on a PT6 engine.

What is Tbo in aviation?

TBO, or Time Between Overhauls, is a time limit specified by the engine manufacturer for a specific engine in a specific installation, after which overhaul is either recommended or mandated depending on how the aircraft is used.

What are three different types of inspections that should be accomplished when overhauling an engine?

There are 3 basic categories of inspection during overhaul: visual, structural non-destructive testing (NDT) and dimensional.

What requires inspection before an aircraft engine is installed?

Is the use of a checklist required when performing an annual or 100-hour inspection of an aircraft engine? … The inside of the cylinders must be inspected with a borescope. The oil must be changed and the filters examined, and the engine given a careful run-up and operational check.

What seven items must be checked before returning a reciprocating engine aircraft to service after an annual or 100-hour inspection?

prior to returning a reciprocating engine to service after a 100-hour inspection, what operational checks must be performed? Check the power output (static and idle r.p.m.), check magnetos, fuel and oil pressure check, cylinder and oil temperature check. Where are life-limited parts of an engine listed?

What is a hot section overhaul?

A hot section inspection (HSI) examines the condition of a number of key engine components between overhauls. Turbine blades, combustion chamber, stators, vane rings, compressors, and more are all scrutinized and diagnosed by our team of FAA certified engineers.

Which are the two main sections of a turbine engine for inspection purposes?

For inspection purpose, the turbine engine is divided into two main sections: the cold and hot. Maintenance of the compressor, or cold section, is one of concern because damage to blades can cause engine failure.
