This bulletin informs operators and maintenance personnel about potential rough engine operation at low speeds caused by float buoyancy loss and fuel regulation issues.
What changed
This new safety information bulletin introduces awareness of service difficulties related to certain BRP-Powertrain float type carburettors. It highlights the investigation initiated by BRP-Powertrain to develop an improved carburettor float design. The bulletin does not mandate any Airworthiness Directive but recommends vigilance and regular inspections.
Why it matters
The bulletin is important for aviation professionals as it alerts them to a potential cause of rough engine operation that could affect flight safety and engine performance. Operators and maintenance organizations need to monitor engine behavior closely to detect early signs of carburettor float issues.
