EASA SIB NE-10-05
Reciprocating (Piston) Engines with Float-type Carburetors
Summary
The Special Airworthiness Information Bulletin SAIB NE-10-05 is an FAA informational bulletin addressing potential hazards associated with reciprocating aircraft engines equipped with float-type carburetors. It applies to all aircraft with such engines and highlights issues like fuel leakage, float damage, and improper fuel metering that can lead to engine stoppage or fire. The bulletin provides detailed guidance for pilots, owners, operators, and maintenance personnel to identify and mitigate these risks.
What Changed
SAIB NE-10-05 updates and expands on previous FAA guidance including SAIB CE-06-33R1 by applying recommendations to all reciprocating engines with float-type carburetors rather than specific models. It offers more detailed explanations of float design issues and focused recommended actions to prevent carburetor-related accidents and incidents.
Why It Matters
This bulletin is important for aviation professionals because float-type carburetor failures have caused numerous accidents over the past 20 years. Understanding the risks and maintenance requirements helps operators and maintenance personnel prevent engine power loss and fire hazards, thereby enhancing flight safety and compliance with recommended overhaul intervals.
What To Do
Pilots should inspect for fuel leaks and abnormal engine behavior during preflight and operation, reporting concerns to qualified maintenance personnel. Owners and maintenance staff must perform routine inspections for fuel leakage and follow all manufacturer maintenance instructions, including overhauling carburetors at engine overhaul intervals or every 12 years or 2,400 hours, whichever comes first. Carburetors showing signs of leakage should be removed and repaired by qualified facilities.
