Overview
Certain smoke system components are located within the engine compartment and therefore exposed to high heat, vibration, and chemical conditions. To ensure continued safe and reliable performance, these components are subject to a recommended replacement interval.
Replacement Recommendation
The following components may be replaced every 3 years:
• Stainless steel braided hoses
• Injector assembly and fittings
• Injector mounting clamps
Why Replace?
These components operate in a demanding environment and may degrade over time due to:
• Continuous exposure to elevated temperatures
• Engine vibration and mechanical stress
• Contact with smoke oil and combustion byproducts
This degradation may not be visible but can affect performance and safety.
Risks of Continued Use Beyond Service Life
Failure to replace these components at the required interval may result in:
• Potential fire hazard
• Reduced system performance
• Smoke oil leaks within the engine compartment
• Component(s) loosening or detachment from the exhaust system
Replacement Interval
• Service life: 3 years from date of installation
• If installation date is unknown, replacement should be performed immediately
Compliance
Adhering to this replacement schedule is part of proper system maintenance. Smoking Airplanes is not responsible for managing customer's maintenance schedule.
