Goal
The goal of this module is to prepare the learner to be able to identify the correct rigid fluid line materials, construction, and fittings commonly used in aviation fluid systems. This module will cover the various fluid and gaseous systems within aviation that are critical to the safe operation of every aircraft as well as proper installation, inspection, and repair of the various lines and fittings that connect the equipment within each system. Correct and proper inspection, installation, repair, and fabrication of aviation fluid lines and fittings is vital to ensuring each system within an aircraft will operate reliably without fail as a failure of any one of these lines can cause a critical system failure during flight and can have grave consequences.
Lessons
Total Effort: 2 hr 58 min
Module Introduction
Introducing Rigid Fluid Lines
Effort: 10 min
- Distinguish between rigid and flexible fluid lines and identify how they are used.
- Identify common causes of damage to fluid line failures and explain what to do when a damaged line is found.
Rigid Fluid Lines Materials
Effort: 16 min
- Identify and discuss the characteristics of common materials used in rigid fluid line manufacturing and choose when each tubing material type should be utilized based on certain factors.
- Properly identify the size and material of original rigid fluid tubing installed within an aircraft in order to provide correct maintenance and repair as well as matching replacements.
Fabricating Rigid Fluid Lines
Effort: 1 hr 42 min
- Describe how to create a flareless fitting and demonstrate the process.
- Describe the tube forming process, identify the tools required, and demonstrate a successful tube bend.
- Explain and demonstrate the process for constructing single and double tube flares.
- Explain how to form a bead on a tubing line and demonstrate the process.
- Identify common flaws in tube flaring and the problems these flaws cause.
Fabricating a Tube Assembly
When inspecting fluid lines on an aircraft, you may come across a line that is damaged. Inspect the tubing closely to determine if a simple repair is needed or if the line needs to be replaced. If a fluid line assembly is damaged beyond repair, you will need to buy one or fabricate your own. ...
Rigid Fluid Line Identification, Fittings, Installation, Inspection, and Repair
Effort: 48 min
- Maintain proper identification for rigid fluid lines and assemblies including markings, decals, and tags.
- Identify and select fitting types and materials for connection to and repair of various rigid fluid line assemblies.
- Identify the installation procedures for fittings and rigid tube assemblies including fitting selection, proper torque, amount of bend, and fitting selection.
- Inspect and identify rigid fluid lines for damage, evaluating lines for necessary repair or replacement.
