Introduction
This Special Airworthiness Information Bulletin informs you of an
airworthiness concern for Alpha Aviation (formerly Robin) Model R2100
(including Model R2160) airplanes.
Background
When the carburetor heat is selected, there have been instances where
the carburetor duct collapsed, which resulted in restricted engine
airflow and an associated loss of power.
The Civil Aviation Authority of New Zealand (NZCAA) has issued
Continuing Airworthiness Notice (CAN) number 75-001, dated August 6,
2008, and has provided this information to the FAA as airplanes of
these types are registered in the United States. A copy of this CAN is
attached for reference. The CAN is based on Alpha Aviation Service
Bulletin number AA-SB-71-003, but also has additional information in it
relevant to inspecting the carburetor ducting. This service bulletin
specifies the inspection and possible replacement of certain carburetor
ducting.
At this time, this airworthiness concern is not an unsafe condition that would warrant AD action under 14 CFR part 39.
Recommendations
We recommend all owners and operators comply with actions outlined in NZCAA Continuing Airworthiness Notice number 75-001.
