ATA 12 – Grease Change
All
AeroShell 33MS grease is used as a lubricant in several areas of the King Air airplane. AeroShell has renamed this grease Aeroshell Grease 64. These greases meet the same military standard, MIL-G-21164D. Operator concerns about the close similarity between the product names, AeroShell Grease 33 and AeroShell Grease 33MS, and the possibility of a wrong grease being used in the wrong application, resulted in the name change.
