What condition does a cracked or chafed pitot tube indicate regarding airworthiness?
Answer: The pitot tube must be replaced before flight
A cracked or chafed pitot tube compromises airspeed indication and is an unairworthy condition requiring replacement before flight.
In aircraft fabric covering, what is the purpose of the dope applied over the fabric?
Answer: Tighten and weatherproof the fabric and provide a paintable surface
Dope tautens the fabric as it dries, seals it against moisture, and provides a base surface for finish coats.
Which inspection method is most effective for detecting fatigue cracks in aluminum wing skin that are not visible to the naked eye?
Answer: Eddy current inspection
Eddy current inspection detects subsurface and surface cracks in non-ferrous metals like aluminum without requiring surface preparation.
What is the function of an anti-ice system on the leading edge of a wing?
Answer: Prevent ice from forming on the leading edge surface
Anti-ice systems prevent ice from forming by heating or chemically treating the leading edge surface, while de-ice systems remove ice after it forms.
When a technician finds that a turnbuckle in a control cable system is improperly safetied, what is the correct action?
Answer: Remove the existing safety wire, verify thread engagement, and re-safety properly
The turnbuckle must be checked for proper thread engagement (no more than 3 threads exposed), then re-safetied correctly per AC 43.13.
What structural member in a semi-monocoque fuselage primarily resists torsional loads?
Answer: The stressed skin
In a semi-monocoque structure, the stressed skin carries the majority of torsional loads, distributing them across the fuselage surface.
What is the maximum number of threads that may be exposed outside a turnbuckle barrel after adjustment?
Answer: 3 threads
AC 43.13-1B specifies that no more than 3 threads may be exposed outside either end of a turnbuckle barrel after final adjustment.
