Mark, what do the red encircled dash /dash asterisk as per page of catalogue I have just sent mean?

Have you got a chance to look into?

Mark, with regard to Boeing SB737-55A1070, two pages of compliance was emailed, It is a little odd that according to table5 (page2) putty has to be applied to the elevator tab hinge bolt and the bolt has to be inspected initially???? before every flight as a preflight task????!!!!

Mark, My question is not specifically about 737 model, the issue was experienced in F27 Mk0050 for which hydraulic pressurization by electric motor driven pump is an approved ICA without any limitation so that you should normally expect both main gears and even nose gear retract simultanously , so I am asking in general whether three phase supply power quality can affect the performance of electric motor driven pump, regardless of airplane type and model?
I have just emailed MM pages.......

Mark, how can I examine the quality of 3 phase power supply of electric motor driven pump, as I believe poor quality power has made pump faild building up sufficient pressure to retract main gear

Which sort of electrical faults, either in aircraft electrical. system or the electric drive of pump, would make electric motor driven hydraulic pump fail to retract main gear?

Mark, which components may be the culprits if main gear can be retracted by engine driven pump but it can not be retracted by electrical driven pump?

Mark, how likely antiskid wiring may have hidden failure that can not be detected through EWIS inspection program established further to cable separation implemented by the type certificate holder?

How is proximity switch different from micro switch regarding wheel speed sensor?
