August 2014- This Special Airworthiness Information Bulletin (SAIB) is to alert owners, operators, and
maintenance technicians of Piper Aircraft, Inc. (Piper) Models PA-28, PA-32, PA-34, PA-44, and
PA-46 series airplanes of an airworthiness concern, specifically structural deterioration and possible
collapse of the air inlet hose. The air inlet hose may be between the air filter and the fuel injector,
carburetor or carburetor heat box depending on the airplane model. A collapsed hose reduces airflow
to the engine and could result in a rough running engine or a loss of power.
