Airworthiness Directives; Lycoming Engines Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
??????????????????????????????????
SUMMARY: 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.
DATES: This AD is effective March 27, 2012.
The Director of the Federal Register approved the incorporation by reference of a certain
publication listed in the AD as of March 27, 2012.
