Which type of damage to a fiberglass composite panel requires the use of a wet layup repair technique?
Answer: Deep delamination or penetration damage through multiple plies
Deep delamination or through-penetration damage requires wet layup repair to restore the original strength of the composite laminate.
What is the purpose of a flow control valve in an aircraft pneumatic de-ice boot system?
Answer: To direct pressurized air to inflate boots in a specific sequence
Flow control (distributor) valves sequence the inflation of individual de-ice boots to cycle the ice-breaking action along the leading edge.
When inspecting a welded steel tube fuselage, what defect would require the affected tube to be replaced rather than rewelded?
Answer: A crack that extends more than one-third of the tube's circumference
Cracks exceeding one-third of the tube's circumference compromise structural integrity to a degree that rewelding cannot adequately restore.
What is the purpose of a shimmy damper on a nose gear landing gear assembly?
Answer: To dampen lateral oscillations of the nose wheel during ground operations
A shimmy damper is a hydraulic device that absorbs the rapid side-to-side oscillation (shimmy) of the nose wheel on the ground.
According to FAR Part 43, what records must be made after completing a 100-hour inspection?
Answer: A description of work performed, the date, aircraft total time, and the signature and certificate number of the person approving return to service
FAR 43.9 and 43.11 require a signed maintenance record entry including the description of work, date, aircraft total time, and approving person's credentials.
What does the term 'fail-safe' mean as applied to aircraft structural design?
Answer: If one load path fails, alternate structure carries the load to prevent catastrophic failure
Fail-safe design ensures that failure of a single structural member does not lead to catastrophic failure because redundant load paths carry the remaining load.
What is the correct procedure when a mechanic discovers that a part installed on an aircraft is suspected to be an unapproved part?
Answer: Remove the part, retain it, and report the finding to the FAA and document it in the aircraft records
Suspected unapproved parts (SUPs) must be removed, quarantined, and reported to the FAA per FAA Order 8120.10, with documentation in the aircraft records.
