They were the only legacy carrier I believe that didn't have a defected pylon when they were grounded after AA191.
I am pretty sure it was due to the fact that at the time, all of NW's DC-10s were PW-powered series -40's. Everybody else was using GE-powered models, and if correct, the pylon design was different between the PW and GE models.
That could be the case, although I bet if NW really wanted to they could have devised a similar procedure to save time and cut costs. AA and CO used a forklift, UA used a crane. Regardless, NW didn't question McDonnell Douglas's advisement.
