That report gets at the root of the problem to begin with (root cause analysis): but it has to be 1 size fits all, it doesn't matter if the requirements aren't identical! On the bright side, the "commonality" between the Black Hawk and the Sea Hawk (UH-60 series to SH-60 series) was a whole lot less than was advertised when the Navy made the decision to use the S-70 as the airframe for their LAMPS requirement. But that's another story. "Parts commonality" is one of those terms that I discovered over time is loaded.
