Question 1

What is the purpose of an 'overhaul' as defined in 14 CFR Part 43, Appendix D?

Accepted Answer

Restoring an item to a like-new condition using FAA-approved data and within new-part tolerances

Answer

An overhaul restores a component to new-part tolerances using FAA-approved data, verifying all dimensions are within limits specified for new parts.

Question 2

A technician discovers a crack in an aircraft skin panel. What is the FIRST action before determining repair procedure?

Accepted Answer

Consult the aircraft's Structural Repair Manual (SRM) for approved repair data

Answer

Before any repair action, the technician must consult approved data — the SRM or FAA-approved equivalent — to determine the correct inspection and repair procedure.

Question 3

Which rivet is recommended when riveting dissimilar metals that cannot be anodized after assembly to prevent galvanic corrosion?

Accepted Answer

Monel rivet

Answer

Monel rivets are used where galvanic compatibility is critical, particularly when joining stainless steel or other metals that would create severe galvanic couples with aluminum rivets.

Question 4

According to FAA AC 43.13-1B, what is the minimum edge distance for a rivet hole measured from the center of the hole to the edge of the sheet?

Accepted Answer

2 times the rivet diameter

Answer

AC 43.13-1B specifies a minimum edge distance of 2D (twice the rivet diameter) from the rivet centerline to the nearest sheet edge.

Question 5

What condition is indicated when a hydraulic system's relief valve opens frequently during normal operations?

Accepted Answer

The pump output exceeds the system's demand or a downstream component is blocked

Answer

Frequent relief valve opening indicates the pump is producing more pressure than the system can use, often because a component is blocked or the pump is oversized for the demand.
