I am interested in examples of 747 tech crew airline procedures which have changed due to other aviation accidents or incidents. They don't have to be big, high profile, international accidents. Even small incidents which may have occured on the ramp/ground and led to a policy change.
An exmaple (of a high-profile one) is I believe some airlines have strict rules on minimum CWT quantities and fuel circuit breaker resetting as a result of TWA-800.
Thanks in advance.
