Propeller issues are one of the most frequent problems encountered by pilots, and spun props are among the most serious. When a prop spins, it can cause extensive damage to the engine, propeller, and even the aircraft itself.

In this article, we will discuss the causes of spun props and provide step-by-step instructions on how to fix them. We will also discuss the importance of regular inspections of your propeller and how to prevent spun props in the future.
What Is A Spun Prop?
A spun prop is a propeller that has been damaged due to excessive force being applied to the blades. This can happen when the propeller strikes an object such as a tree or another aircraft, or when the engine suddenly stops while the propeller is still spinning. The sudden change in momentum can cause the propeller to bend or break, and the damaged blades can whip around and cause even more damage.
Spun props can be very dangerous, and they can even lead to a fatal accident. If you ever experience a spun prop, it is important to land the aircraft immediately and have it inspected by a qualified mechanic.
Causes of Spun Props
There are several different factors that can contribute to a spun prop, including:
- Propeller strikes
- Engine failure
- Imbalance
- Improper maintenance
Propeller Strikes
Propeller strikes are the most common cause of spun props. This can happen when the propeller strikes an object such as a tree or another aircraft. Even a small propeller strike can cause enough damage to cause the prop to spin.

Engine Failure
A sudden engine failure can also cause a spun prop. This is because the propeller is no longer being driven by the engine, and the momentum of the propeller can cause it to continue spinning.
Imbalance
An imbalance in the propeller can also cause it to spin. This can happen if the propeller is not balanced properly, or if one of the blades is damaged.
Improper Maintenance
Improper maintenance can also lead to a spun prop. This includes not properly greasing or tightening the propeller bolts, or not inspecting the propeller regularly for damage.
How to Fix a Spun Prop
If you experience a spun prop, it is important to land the aircraft immediately and have it inspected by a qualified mechanic. The mechanic will need to assess the damage and determine the best course of action. In some cases, the propeller may be able to be repaired, while in other cases it may need to be replaced.
If the propeller can be repaired, the mechanic will need to:
- Remove the damaged propeller blades
- Inspect the propeller hub for damage
- Balance the propeller
- Reinstall the propeller blades
If the propeller cannot be repaired, it will need to be replaced. The mechanic will need to:
- Remove the damaged propeller
- Install a new propeller
- Balance the new propeller
