Service bulletin SB-09-31
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
FREIGHTLINER: SOME TRUCKS HAVE BEEN FOUND WITH INCORRECT SEALING OF AIR INTAKE DUCT ASSEMBLIES, ALLOWING UNFILTERED AIR TO BYPASS THE AIR CLEANER. LOOSE DUCT CONNECTIONS OR DIRT FOUND IN THE DUCTING DURING A FILTER SERVICE INDICATE THAT DUCT CLAMPS SHOULD BE CHECKED, AND RUBBER SEALS ADDED WHERE NOT PRESENT. LOOSE DUCTING SHOULD BE THOROUGHLY INSPECTED FOR DAMAGE AND REPLACED IF NECESSARY. NO MODEL YEARS LISTED. *PE
