How to Use Aviation Snips: A Guide for Aircraft Mechanics and Inspectors
Aviation snips are an essential tool for aircraft mechanics and inspectors, as they can be used for various applications such as trimming and trimming of aluminum alloy parts, cutting and forming metal tubing and sheet stock, and preparing parts for riveting, welding, and bonding.
What are Aviation Snips?
Aviation snips, also known as aviation bolt cutters or metal cutting scissors, are a specialized tool used to cut through metal using a combination of pressure, leverage, and a hard, high-strength jaw. They are designed for use on small and sensitive aircraft components, requiring a higher level of precision and finesse than standard bolt cutters.
Why Use Aviation Snips?
• Accuracy and precision: Aviation snips allow you to cut precisely where needed, without compromising the shape or structure of the adjacent material.
• Soft-jaw construction: This design ensures minimal scratching and damage to nearby components during cutting operations.
• Ergonomic handle design: Reduces fatigue and provides improved grip control.
Choosing the Right Aviation Snips
Before learning how to use aviation snips, it is crucial to choose the right snips for the specific job. Here are some essential factors to consider:
Table 1: Factors to Consider when Choosing Aviation Snips
| Factor | Description | Recommended Solution |
|---|---|---|
| Gauge range | Compatible with various aluminum and alloy thicknesses. | Specify the required gauge range before selecting snips. |
| Type of joint | Ensure compatibility with the type of joint, such as square, L, or C-section cut. | Opt for specific snip types (e.g., cutting snips, trimming snips). |
| Precision desired | Assess the requirement for high accuracy, soft-jaw or rugged industrial-grade construction. | Balancing precision with durability. |
| Accessibility and dexterity | Consider mobility and maneuverability of operator. | Light-weight ergonomically designed snips. |

Pre-Cutting Considerations
• Eye protection: Wear protective safety glasses to ensure the metal shavings or fragments from cutting do not harm eyes.
• Secure operating area: Work on a stable surface or rig support to prevent any potential movements or slipping of the subject material.
Step-by-Step Operation
- A. **Holding and positioning**
1. **Hold snips in a firm and secure way**: Use the handles grip to secure your snip, maintaining an open-and-close movement throughout the task.
2. **Target the specific spot**: Keep the cutting action targeted with the precision expected, aligned with the specified section
B. **Cleansing the cut-line area (optional)**
a. Pre-clean the intended cutting position with a tool to protect the area where cutting edge will interact (using tweezers and an adhesion surface brush) This is essential step especially.
