What this exam covers
5 real sample questions
Which group contains typical potable-water system components?
A. Tank, service fittings, pump or pressure source, heaters, valves, lines, and outlets
B. Tank, vacuum blower, flush valve, rinse ring, drain mast, and collection fittings
C. Reservoir, accumulator, pressure regulator, actuators, filters, and return lines
D. Cylinder, regulator, distribution manifold, masks, shutoff valves, and relief devices
Show answer and reasoning

Correct answer: A. Tank, service fittings, pump or pressure source, heaters, valves, lines, and outlets

Potable-water systems store, pressurize, distribute, heat, drain, and service water through sanitary components designed for that purpose.

  • B: Magnetos and plugs belong to engine ignition.
  • C: Rotor hardware belongs to helicopter flight controls.
  • D: Brake components are unrelated to potable-water distribution.

What is the purpose of a positive downlock in a retractable landing-gear system?
A. Secure extended landing gear against collapse under applied loads
B. Increase wheel-tire inflation pressure during gear retraction
C. Center the nosewheel through main-brake hydraulic pressure
D. Prevent hydraulic return flow from reaching the system reservoir
Show answer and reasoning

Correct answer: A. Secure extended landing gear against collapse under applied loads

A downlock mechanically or hydraulically secures the gear in the extended position so landing and ground loads cannot drive it toward retraction. Indication must correspond to actual lock condition.

  • B: Tire pressure is independent of the gear downlock.
  • C: Nosewheel centering uses separate geometry or mechanisms.
  • D: Fluid routing may support operation, but the downlock's defining function is securing the extended gear.

Which characteristic identifies a bladder-type fuel cell?
A. A rigid integral cavity sealed at its structural seams
B. A removable metal container supported by mounting straps
C. A flexible removable container supported inside a structural cavity
D. A self-sealing rigid tank forming part of the aircraft exterior skin
Show answer and reasoning

Correct answer: C. A flexible removable container supported inside a structural cavity

A bladder cell is a flexible fuel-tight container installed in a supporting compartment. Security, anti-chafe provisions, venting, fittings, and freedom from wrinkles are essential.

  • A: A machined rigid tank is not a bladder cell.
  • B: Integral or wet-wing construction uses sealed aircraft structure, unlike a removable bladder.
  • D: Bladder cells still require approved venting.

Why are conductive paths bonded across movable control-surface hinges?
A. To maintain hinge alignment when aerodynamic loads reverse direction
B. To provide a redundant mechanical attachment for the control surface
C. To provide a low-impedance lightning and static-current path around bearings
D. To prevent electrical loads from changing control-cable rigging tension
Show answer and reasoning

Correct answer: C. To provide a low-impedance lightning and static-current path around bearings

Bonding jumpers bridge joints whose bearings or hinges may not provide a reliable conductive path. This limits arcing, pitting, and electromagnetic effects during lightning or static discharge.

  • A: Bonding straps do not supply bearing lubricant.
  • B: Cable rigging is independent of electrical bonding.
  • D: The jumper has negligible aerodynamic purpose.

A skid tube has a dent at a step attachment. Why is location important?
A. The step attachment reduces load in the tube, making nearby dents less critical
B. Attachments concentrate loads, requiring location-specific damage evaluation
C. Skid-tube dents are evaluated by depth alone regardless of nearby attachments
D. The step transfers landing load away from the skid tube into the cabin floor
Show answer and reasoning

Correct answer: B. Attachments concentrate loads, requiring location-specific damage evaluation

Steps and cross-tube fittings introduce concentrated bending and attachment loads. A dent acceptable elsewhere may be prohibited near these high-stress zones.

  • A: Skid damage can reduce section strength.
  • C: Skids transmit landing and ground loads.
  • D: Damage does not improve vibration stability.
