### **Bendix 10-79020-17 Magneto: Pros and Cons**

The **Bendix 10-79020-17** is a high-performance magneto commonly used in aircraft engines, particularly in piston-powered general aviation aircraft like the Cessna 172, 182, and other Lycoming/Opposed engines. Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros of the Bendix 10-79020-17 Magneto**

1. **Proven Reliability**

The Bendix brand has a long-standing reputation for durability and consistent performance in aviation applications. This magneto is designed to withstand high RPMs and demanding operating conditions, making it a trusted choice for pilots and mechanics.

2. **High Performance and Efficiency**

It is engineered to provide strong spark output, ensuring reliable ignition even under stress. This is critical for engines operating at high altitudes or in hot climates, where performance degradation is a concern.

3. **Compatibility with Common Engines**

The **10-79020-17** is specifically designed for engines like the **Lycoming O-320, O-360, and IO-360**, as well as some Continental engines. Its widespread use means that replacement parts, diagnostics, and maintenance procedures are well-documented.

4. **Long Service Life with Proper Maintenance**

With regular inspection, gap adjustment, and cleaning, this magneto can last for tens of thousands of hours. Many aircraft owners report that a well-maintained Bendix magneto can outlast the engine itself.

5. **Easy to Service and Repair**

Compared to some modern electronic ignition systems, the Bendix magneto is relatively simple to disassemble, inspect, and repair. Basic tools and a few specialized components (like brushes and timing gears) are often sufficient for maintenance.

6. **Redundancy and Safety**

Most aircraft engines use **two magnetos** (left and right), meaning if one fails, the other can keep the engine running. This redundancy is a key safety feature in aviation, and the Bendix 10-79020-17 is a reliable backup option.

7. **Lower Cost Compared to Some Alternatives**

While not the cheapest component, it is generally more affordable than some high-end electronic ignition systems, especially when considering long-term reliability.

8. **Minimal Electronic Dependence**

Unlike modern electronic ignition systems, the Bendix magneto does not rely on batteries, solenoids, or complex wiring. This reduces the risk of electrical failures, which can be critical in remote or high-altitude operations.

---

### **Cons of the Bendix 10-79020-17 Magneto**

1. **Mechanical Wear Over Time**

As a mechanically driven component, the magneto relies on moving parts (gears, brushes, and bearings) that can wear out. This requires periodic inspection and replacement of consumable parts, such as brushes and timing gears.

2. **Sensitivity to Misalignment**

If the magneto is not properly aligned with the engine s timing marks, it can cause **backfiring, rough idling, or even engine damage**. This requires precise installation and occasional rechecking.

3. **Limited Lifespan Compared to Electronic Ignition**

While durable, magnetos typically have a **shorter lifespan** than modern electronic ignition systems (e.g., **Bendix KEC-20 or MS20A**). Over time, wear on internal components can lead to reduced performance or failure.

4. **Requires Regular Maintenance**

- **Brush replacement** (every 1,000 2,000 hours)

- **Gap adjustment** (typically every 500 hours)

- **Cleaning of internal components** (to prevent carbon buildup)

- **Timing checks** (to ensure proper alignment with the engine)

Neglecting maintenance can lead to premature failure.

5. **Higher Noise and Vibration**

The mechanical nature of the magneto can introduce slight **vibration and noise** compared to smoother electronic systems. While usually negligible, some pilots may notice a difference in engine smoothness.

6. **Limited Availability of New Parts**

While still widely available, some older or less common Bendix magnetos may have **discontinued parts**. This can make long-term ownership slightly more challenging if replacement components become scarce.

7. **Slightly Higher Initial Cost Than Basic Alternators**

Compared to a simple **alternator-based ignition system**, the Bendix magneto is more expensive upfront. However, its reliability often justifies the cost for serious pilots.

8. **Potential for Carbon Buildup**

If the engine s fuel mixture is rich or if oil burns excessively, carbon deposits can form inside the magneto, affecting performance. Regular cleaning is necessary to prevent this.

### **Conclusion and Recommendation**

The **Bendix 10-79020-17 magneto** remains one of the most reliable and widely trusted ignition components in general aviation. Its **mechanical simplicity, durability, and proven performance** make it an excellent choice for pilots who prioritize **safety, redundancy, and long-term reliability**.

However, it is **not a maintenance-free component**. Owners must commit to **regular inspections, brush replacements, gap adjustments, and timing checks** to ensure optimal performance. For pilots who are **not comfortable with mechanical maintenance**, an electronic ignition system (such as the **Bendix KEC-20 or MS20A**) may be a more convenient alternative, though with slightly different reliability trade-offs.

- You operate in **high-demand or remote environments** where reliability is critical.

- You are willing to **perform regular maintenance** (or have a mechanic do so).

- You prefer **mechanical redundancy** over electronic systems.

- Your aircraft is **older or not equipped with modern electronic ignition**.

- You want **lower maintenance requirements**.

- You prioritize **modern diagnostics and troubleshooting ease**.

- Your aircraft is **new or heavily modified** with electronic systems.

For most **Lycoming/Opposed engine aircraft**, the Bendix 10-79020-17 remains a **strong, well-proven choice** especially when paired with proper maintenance. If budget allows, pairing it with a **high-quality electronic ignition system** (as a backup) can further enhance safety.
