Cessna Airbox Assembly, FAA PMA Approved

Approved Replacement Part Number: 
0750144-1, 0750144-33


As the leader in firewall forward STC products for Cessna™ single aircraft Air Plains is all too familiar with customers "airbox woes".  Until now customers had to choose between temporary repairing their airbox or purchasing a new airbox from Cessna™.  The problem is that both options can be very expensive, and the final product is still an airbox susceptible to several common issues.

Air Plains now offers customers a third option; our FAA-PMA approved APS0750144-33 airbox provides MORE DURABILIY and MORE VALUE over previous options for 180, 182, and 188 owners. 

When we developed our PMA airbox we looked at the common issues with the factory airbox and identified several areas for improvement. Our PMA approved airbox features structural adhesive reinforcement in the highest stress areas of the skin and airbox collar, this distributes the stress between the skins and prevents the common cracking and collar separation issues seen all too often.  The shaft is made from corrosion resistant steel and the troublesome needle bearing is replaced by a more robust oil-impregnated bronze bushing which eliminates the risk of needle ingestion by the engine.

APS0750144-33 also features Air Plains improved PMA approved APS0750111-19 arm which is manufactured from hardened steel and has a larger bearing area for the clamp; this significantly reduces the wear from the cable clamp.  The result of these improvements is an airbox superior to the factory original which will provide many more years of trouble-free service.
