>>> The owner at the shop told me that they only use Aeroshell 22
because it is required for certified aircraft that a certified grease be
used. He said
other equivalent greases are available and would be as good or better
but
were not certified for use on aircraft. >
This was one of the reasons why the list of alternative greases was
supplied in the recent service bulletin. In some countries Aeroshell 22
is almost impossible to get in small quantities so suitable equivalents
have been listed.
