Union Warns New Odorless Engine Oil May Mask Toxic Fumes

A new aviation oil, Eastman Turbo Oil 2330, is being trialed on aircraft to eliminate odor and reduce cabin odor incidents and unplanned maintenance. The oil’s lack of scent, however, could conceal harmful fumes that have historically caused headaches, dizziness, irritation and other symptoms in crews. A union spokesperson has cautioned that the odorless design may allow toxic gases to accumulate unnoticed, potentially exposing flight attendants and pilots to hazardous conditions. The trial is currently limited, but the warning highlights the need for additional monitoring of cabin air quality during testing.
