SAIB Highlights Air Intake Issue for Select Piper Airplanes

 The FAA issued Special Airworthiness Information Bulletin (SAIB) CE-14-23 on Aug. 6 that details a concern with the deterioration and possible collapse of the air inlet hose on Piper model PA-28, PA-32, PA-34, PA-44, and PA-46 airplanes. The air inlet hose may be between the air filter and the fuel injector, carburetor, or carburetor heat box depending on the model. A collapsed hose reduces airflow to the engine and could result in a rough running engine or a loss of power. 

            The SAIB recommends that owners inspect the air inlet hose of each airplane’s engine(s) within the next 25 hours of time in service to verify that it is an approved Piper part. The SAIB calls for replacement of the hose if it is not an approved part, or if it exhibits any of the following conditions: broken or loose cords on external surface; loose or displaced supporting wire; signs of wear, perforation, deterioration or collapse.
