747 Flap Load relief
Boeing in the 747 maint manual states that the flap load relief will prevent excessive airloads on the flaps by retracting T/E flaps from 30 to 25 & 25 to 20 if it approaches within 2 kts of the placard limit. As a LAME this does not initiate an inspection unless it is reported in the log that a flap placard SPD was exceeded & by how much, in this case 1 & 15 kts are the 2 criteria of interest, (Phase I or Phase II inspection required). It would be up to the pilots to monitor IAS Vs Flap Ref. and report if required.
Mr Boeing does not like change so I can assume the 737-800’s will be very similar if installed.
