Airframe Grease Update SAE International's AMS- M Committee on Aerospace Greases, a group which includes grease sup pliers and aircraft manufac turers, has finished developing a standard for general- purpose airframe greases. Already in use at Boeing and Airbus, the standard should receive final SAE approval early this year, indicates committee Chairman Geoff Bishop, of Shell Aviation Ltd. in London. The standard, which will be assigned a number upon adoption, was based on an earlier Boeing specification, BMS3-33. One of its goals is to counteract the proliferation of airframe lubes pre scribed for aircraft — a trend that has required the use of scores of lubricants on some commercial planes. The standard will help streamline lube inven tories, and reduce the risk of applying the wrong grease product. Boeing says it will allow operators to use a single grease on all but nine of the 359 lubrica- tion points on Boeing 737s.
