Card 1
Question: What does 'Fail-safe' refer to in aircraft systems maintenance context?
Answer: A design philosophy ensuring that if a component fails, the structure or system retains enough strength or redundancy to prevent catastrophic failure
Card 2
Question: Define 'Safe Life' as used in aircraft maintenance.
Answer: A design concept where a component is retired after a predetermined service life to prevent failure (called 'Safe Life').
Card 3
Question: What is 'Fatigue' in the context of aircraft structures?
Answer: Progressive and localized structural damage that occurs when a material is subjected to cyclic loading ('Fatigue').
Card 4
Question: What does 'Shear' describe in structural terms?
Answer: A type of internal force that causes one part of a material to slide past another ('Shear').
Card 5
Question: What is 'Tension' in structural loading?
Answer: A force that pulls material apart, producing tensile stress ('Tension').
Card 6
Question: What is 'Torsion' in aircraft structural loads?
Answer: A twisting force that produces shear stresses in a structure ('Torsion').
Card 7
Question: What is meant by 'Static loads' on an aircraft?
Answer: Loads that are constant or slowly varying with time, as opposed to dynamic loads ('Static loads').
Card 8
Question: What is 'Strain' in the context of structures?
Answer: The deformation per unit length resulting from applied stress ('Strain').
Card 9
Question: What does 'Stress Concentration Factor' refer to?
Answer: A multiplier that quantifies how much stress increases near discontinuities like holes or notches ('Stress Concentration Factor').
Card 10
Question: What is 'Stress Corrosion' as listed in the index?
Answer: A corrosion process assisted by tensile stress that leads to cracking ('Stress Corrosion').
