Day 3 Progress Check Flashcards
What distinguishes the monocoque structure from the semimonocoque in terms of load-bearing?
Semimonocoque uses both skin and internal framework to support loads.
How is a surface repair patch typically installed on aircraft skin?
By installing a patch over the external surface, often called a scab patch.
In aircraft surface repairs, how is the dimension of a chamfer typically determined?
3 to 4 times the material thickness from the edge into the surface.
What is one key element of aircraft wings as described in the SRM?
Wings typically have at least two spars, front and rear.
What are longerons primarily responsible for in an aircraft’s structure?
Providing structural integrity against twisting and bearing tension.
What is the primary function of stringers in aircraft structural design?
To prevent twisting and manage tension, similar to longerons but lighter.
According to the Basic Sheet Metal Structural Repair Manual, what type of patch should be designed for a crack repair?
A repair patch double the size of the damaged area.
Which of the following is NOT a chapter covered under the ATA Codes’ Aircraft Structures?
Chapter 60 Control Surfaces
What is the main difference in the classification between primary and secondary aircraft structures?
Primary structures are essential for flight; secondary structures are not.
What type of wings relies entirely on the wing’s own structure for support?
Cantilever Wings
Which chapter of the ATA Codes focuses specifically on wing repairs and maintenance?
Chapter 57 Wings
What is the purpose of using ATA Codes in aircraft maintenance documentation?
To standardize the filing and retrieval of commercial aircraft information.
In the context of the SRM, what is the role of gussets?
To join and reinforce structural members like frames and stringers.
How should repairs be executed if the aircraft has a Structural Repair Manual (SRM)?
In compliance with the SRM or applicable Engineering Orders, no exceptions.
Which ATA chapter deals specifically with the fuselage?
Chapter 53 Fuselage
