Caution: With TN4049 (neo-Winglets) executed, the max. take-off and landing
mass will remain 472 kg / 1041 lbs. for variant LS4 and will be reduced to 505 kg /
1113 lbs.for variants LS4-a and LS4-b with neo-Winglets installed.
max. flight mass without waterballast: W
max. of non lifting parts W
Caution: With TN4045 (winglets) executed, the max. mass and the max. mass of
the non lifting parts are reduced by 10 kg (22 lbs.). The max. amount of
waterballast is limited to 100 kg (220 lbs.)
Caution: With TN4049 (neo-Winglets) executed, the max. mass of the non-lifting
parts is 250 kg / 551 lbs. for all LS4 variants with and without neo-Winglets
installed (TN4046/4047 must be performed).
The determination of the max. mass of the non-lifting parts in relation to the empty
mass C.G. according to section 2.4 is not applicable.
Note: TN 4046 (manual revisions) and TN 4047 (increase of mass of non lifting
parts) don't apply for LS4-b only, but also for LS4 and LS4-a (TN LS-S-01).
