Whilst doing some research on this question, I found the following:

"French airworthiness directive 2002-368(B) states that a conversion error
with regard to applied torque values (metric units to U.S. Customary Units)
specified in Airbus Service Bulletin A330-57-3067, dated October 12, 2000;
and Revision 01, dated April 10, 2001; has been identified. This error might
lead the operators using U.S. Customary Units to apply a torque value being
less than those required, which could lead to a loose nut."

Some people say that metrication would be a major expense. This is yet
another example of the continuing expense of running two (or more) parallel
measuring systems.
