AT 209 - Assignment 1 - Wiring Harness Inspection

10 points

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 harne`ss 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

A visual inspection of the wiring harness was conducted in accordance to my reading of the FAA AC 43.13-1B - Chapter 11, Section 8-12. The inspection was focused on several key areas, including the overall condition of the wires, the integrity of the insulation, the state of the connectors, any possible signs of overheating, and how the harness was routed and secured inside the assembly. Starting with the wires themselves, there were no obvious cuts, cracks, abrasions, or exposed conductors that could cause a problem. The wires looked pretty solid overall, and there wasn’t any fraying that I could notice. Looking closer at the insulation, it also appeared to be in good shape, with no missing tape or torn covering, and I didn’t see anything that looked like heat damage or melted conduit. The connectors seemed to be in good working order too. They were locked in place and not loose, and I didn’t find any bent pins, broken clips, or visible corrosion. This is important since a bad connector could easily lead to intermittent faults or electrical issues. In summary, the wiring harness appeared to be in good condition with no major defects or concerns. This was also one of the Purdue Archers so they were in good shape to ensure safe operations for the students.
