Airframe Mechanic Certification Aircraft Systems & Components 4

Question 1

What is the function of a torque tube in an aircraft control system?

Accepted Answer

Transmit rotational motion to move control surfaces

Answer

A torque tube transmits rotational (torsional) loads to actuate control surfaces such as flaps or ailerons.

Question 2

What is the main advantage of a wet wing fuel tank design compared to a bladder tank?

Accepted Answer

Higher fuel capacity for the same structural weight

Answer

Wet wing tanks use the sealed wing structure itself as the fuel tank, maximizing usable volume without the weight penalty of a separate bladder or tank.

Question 3

An aircraft uses a push-pull tube control system. What is the primary advantage over a cable system?

Accepted Answer

Ability to transmit both tension and compression loads

Answer

Push-pull tubes can carry both compressive and tensile loads, providing positive control in both directions without requiring turnbuckles or take-up devices.

Question 4

Which FAA document specifies the minimum inspection requirements for a particular aircraft's airframe?

Accepted Answer

The aircraft's FAA-approved Maintenance Manual

Answer

The FAA-approved Maintenance Manual (or Airworthiness Limitations section) for a specific aircraft specifies its mandatory inspection requirements.

Question 5

What type of damage is characterized by a series of parallel scratches or grooves on a mating surface caused by relative motion?

Accepted Answer

Fretting

Answer

Fretting damage occurs when two surfaces in contact undergo small oscillatory relative motion, producing parallel scratches and wear debris.
