Wiring Harness Inspection

Overview

This assignment guides students in visually inspecting a wiring harness to identify common defects such as damaged wires, poor connectors, or insulation issues. Students will document their findings with a photo and a brief report, developing essential skills in harness condition assessment for safety and reliability.

Photograph Wiring Harness

Identify a wiring harness from an approved piece of equipment, such as a vehicle, plane, or training/simulator station.

Take a well-lit photo of the wiring harness.

Be sure to capture all ends of the wiring harness (it may run point to point or it may include several breakouts).

Upload your photo(s) to the

Photos⁠

section below.

Report of Findings

Conduct a brief visual inspection of the harness, focusing on the following:

Condition of the wires (check for cuts, cracks, abrasions, fraying, or exposed conductors)

Integrity of insulation and coverings (look for missing tape, damaged conduit, or heat damage).

Condition of connectors (check for corrosion, broken clips, loose or bent pins).

Signs of overheating (burn marks, melted insulation).

Routing and securing (whether the harness is adequately supported, tied down, and clear of moving parts or sharp edges).

Write a short

Inspection Report⁠

(½ to 1 page maximum) that includes:

The photo of the harness.

A summary of your observations. Be sure that your observations use language represented in

FAA AC 43.13-1B - Chapter 11, Sections 8-12⁠

⁠

Any defects or concerns you noticed.

A recommendation (e.g., “harness is acceptable for use,” “minor repair needed,” or “should be replaced”).

Inspection Report

The wiring harness is not in compliance with AC43.13-1B. Althouogh, I am not sure about the insulation type or the current carrying capacity of the wires, the wires are not properly marked at regular intervals. There is no test data that I could find that would show the durability of the wire harness. There are anti-chafe measures used, such as wire wrap and some zip ties to hold parts of the wire harness in place. There are also rubber grommets that mount to the frame, and all exposed connectors are plugged. Serviceability is an issue, as the wires are not marked.
