Abstract
We are adopting a new airworthiness directive (AD) for certain Lycoming Engines reciprocating engines. This AD was prompted by a report of a "machined-from-billet" HA-6 carburetor having a loose mixture control sleeve that rotated in the carburetor body causing restriction of fuel and power loss. This AD requires removing certain "machined-from-billet" Volare LLC (formerly Precision Airmotive Corporation, formerly Facet Aerospace Products Company, formerly Marvel-Schebler (BorgWarner)) HA-6 carburetors, inspecting for a loose mixture control sleeve or for a sleeve that may become loose, repairing the carburetor, or replacing the carburetor with one eligible for installation. We are issuing this AD to prevent engine in-flight shutdown, power loss, and reduced control of the airplane.
