In general aviation, a propeller strike, even one that appears minor, is a critical event that requires immediate attention. According to aircraft engine manufacturers, this type of incident can cause hidden internal damage that, if not detected in time, can develop into a catastrophic failure.
At Aéro Atelier C.M. inc., we take this situation very seriously. A propeller strike or sudden engine stoppage requires rigorous expertise and a complete inspection before the next flight. Our certified technicians carefully follow the official instructions from Lycoming, Continental and Transport Canada to ensure that each engine regains its integrity, safety and original performance.
What is a propeller strike?
A propeller strike is defined as any event in which the propeller comes into contact with an object, whether the engine is running or not. This includes:
- Contact with the ground or an obstacle
- A sudden loss of engine RPM following a collision
- A sudden stoppage caused by water, tall grass or a similar medium
- Any situation requiring more than simple blade dressing
Even if the propeller appears to turn normally after the incident, internal damage may be hidden in the crankshaft, gears, bearings or other critical components. These defects can progress over time and compromise flight safety.
Why a complete inspection is essential
Engine manufacturers’ service bulletins are clear: following a propeller strike or sudden stoppage, complete engine disassembly and a detailed inspection of all rotating components are mandatory before the next flight.
A professional inspection is intended to detect:
- Deformation or cracks in the crankshaft
- Abnormal bearing play
- Unusual marks or wear on internal parts
- The presence of metallic contamination
- Misalignment of rotating components
At Aéro Atelier, we perform complete disassembly, internal inspection, cleaning, testing and return to service of the engine to the industry’s strictest standards. All procedures are carried out in accordance with approved technical documentation, ensuring safe and compliant work.
