THS Jackscrew design
Reading Alaska Airlines flight 261 reports , I wonder why NTSB points out only to DC-9, MD-80/90 and Boeing 717 fleet regarding the jackscrew design considering that (as far as I know) the designs used on the 727,737,747 etc. are similar to the one used on those cited.
Could anyone with technical knowledge on the issue explain how do they differ justifying this differentiation between aircraft types in reports?
