• What is the primary purpose of the aircraft inspection program?
• To improve aerodynamics
• To ensure airworthiness
• To increase speed
• To reduce fuel consumption

Rationale: The inspection program is designed to ensure that an aircraft

remains airworthy by detecting and correcting defects before they become hazards.

• What is the correct method for removing corrosion from aluminum

surfaces? 1 / 4

• Scraping with a steel brush
• Using a mild abrasive and chemical treatment
• Sandblasting aggressively
• Using only water

Rationale: Aluminum corrosion should be removed with mild abrasives and

chemical treatments to prevent further damage or pitting.

• Which type of rivet is typically used in high-stress areas?
• Blind rivet
• Solid shank rivet
• Drive rivet
• Self-piercing rivet

Rationale: Solid shank rivets, such as NAS or AN types, are used in high-

stress structural areas for maximum strength.

• What is the main function of the empennage?
• To increase lift
• To provide stability and control
• To store fuel
• To improve engine performance

Rationale: The empennage includes the horizontal and vertical stabilizers

and controls aircraft stability and balance.

• Which part of an aircraft wing is primarily responsible for lift? 2 / 4

• Flap
• Airfoil
• Spoiler
• Aileron

Rationale: The airfoil shape of the wing generates lift by creating a

pressure difference above and below the wing.

• What is the purpose of a static discharger on an aircraft?
• To prevent engine failure
• To reduce drag
• To dissipate static electricity
• To enhance lift

Rationale: Static dischargers help prevent radio interference by safely

discharging static electricity accumulated during flight.

• Which inspection type is required after major repairs?
• 100-hour inspection
• Return-to-service inspection
• Annual inspection
• Pre-flight inspection

Rationale: After major repairs or alterations, the aircraft must undergo a

return-to-service inspection to verify compliance with airworthiness standards. 3 / 4

• What is the proper torque sequence when installing a multi-bolt aircraft

component?

• Random order
• Crisscross pattern
• Clockwise only
• Counterclockwise only

Rationale: A crisscross torque sequence ensures even load distribution and

prevents warping of the component.

• What type of control surface is used to control pitch?
• Rudder
• Elevator
• Aileron
• Spoiler

Rationale: The elevator, attached to the horizontal stabilizer, controls the

aircraft’s pitch about the lateral axis.

• Which of the following is a primary flight control surface?
• Flap
• Aileron
• Trim tab
• Spoiler

Rationale: Primary flight controls include ailerons, elevators, and rudders,

which control roll, pitch, and yaw.
