Section 1 EO C170.01 – WATCH HOW IT’S MADE SEGMENTS
Resources needed for the delivery of this lesson are listed in the lesson specification located in A-CR-CCP-801/PG-001, Proficiency Level One Qualification Standard and Plan, Chapter 4. Specific uses for said resources are identified throughout the instruction guide within the TP for which they are required.
Review the lesson content and become familiar with the material prior to delivering of the lesson.
Review the How It’s Made segments and select seven segments to show during the lesson.
Prepare a suitable classroom area with an available media.
Nil.
An in-class activity was chosen for this lesson as it is an interactive way to provoke thought and stimulate interest among cadets.
Nil.
By the end of this lesson the cadet shall have watched How It’s Made segments.
Discovering the aircraft maintenance and manufacturing industry will give the cadets a better understanding of how aircraft are prepared for and serviced for flight, including different career opportunities.

Teaching point 1
|
Discuss major components of the aircraft maintenance and manufacturing
industry.
|
|
Time: 5 min
|
Method: Interactive Lecture
|
The terms maintenance and manufacturing refer to very clearly defined fields.
Aircraft maintenance refers to any work being done on an aeronautical product after the issuance of a certificate of airworthiness, to include:
overhaul,
repairs,
required inspection or modification, and
removal or installation of components.
This does not include elementary work or servicing.
Aircraft manufacturing refers to any work being done on an aeronautical product before the issuance of a certificate of airworthiness, to include:
making,
assembly, and
fabrication.
What is considered aircraft manufacturing?
What kind of work is included in aircraft maintenance?
Any work done on an aeronautical product before the issuance of a certificate of airworthiness.
Overhaul, repair, required inspection or modification, and removal or installation of components on an aeronautical product.

Teaching point 2
|
Watch and discuss How It’s Made
segments.
|
|
Time: 40 min
|
Method: In-Class Activity
|
Before the start of the lesson review the How It’s Made segments. This will facilitate the discussion after each segment and will enable an optimal use of the time allotted for this TP.
After each segment, using the questions and answers provided below, confirm the cadets’ comprehension of the segment.
Why is redundancy built in an aircraft engine?
Why is a testing propeller attached to engine during testing?
What is checked in the oil filter after testing?
To ensure that each system as a backup to maximise safety.
To keep the engine cool during the testing phase.
The oil filter is checked for foreign debris.
Why are propellers made of aluminum?
What happens to defective pieces during the manufacturing process?
Why are the back of the blades painted black?
Because aluminum is a light-weight and durable material.
The defective pieces are either repaired or scrapped if they cannot be repaired.
To prevent the sun from reflecting off the propeller and blinding the pilot.
What are wooden propellers made of?
What is the airfoil on a propeller?
What are the two sides of a propeller blade?
The propellers are made of laminated maple.
The airfoil is the side of the propeller blade that is shaped like aircraft wing.
The pitch and the airfoil.
What are the airplanes made of and why?
What is the process called curing?
What is used to cut holes in the planes fuselage?
An airplane can be made out of fiber glass and Carbone fiber.
Curing refers to the process of cooking the different materials at very high temperature in order to solidify the glue.
The holes in the airplanes fuselage are cut using a very high pressure jet of water and sand.
What is the oil used for during the machining process?
What is recycled during the manufacturing of the landing gear?
What is used to protect the landing gear from corrosion?
Oil is used to reduce the heat produce by friction during the machining process.
Metal chips created during the machining process.
The different parts of the landing gear are plated with Cadmium in order to protect them from corrosion.
How many hours of work are required to build a helicopter?
What is the body of the aircraft made of?
What is brake cable used for?
The construction of a helicopter requires about 700 hours or 110 days.
The fuselage of the helicopter is made out of carbon fibre.
Brake cable is used to prevent bolts from loosening due to vibrations.
What created the bases for the fuselage of the glider?
What kind of glue is used to bond the wings together?
Why is the wing cut in two after its assembly?
The bases for the fuselage is created using Kevlar fibre.
The wings are bonded together using epoxy resin.
The wing is cut in two in order to facilitate transportation.
What are the blades of a jet engine used for?
Are the blades machined or moulded?
What indicates imperfections during the inspection process?
The turbine blades are used to generate air pressure inside the jet engine in order to create a mixture of air and gas that will be ignited to create thrust.
The blades are moulded using a dye.
The imperfections will show up as little fluorescent spots under a black light.
The cadets’ participation in the in-class activity will serve as the confirmation for this TP.
The cadets’ participation in the activity in will serve as the confirmation of this lesson.
