Permanent Installation Of Fixed Ballast At Rear Fuselage - DG Flugzeugbau LS10-s Maintenance Manual

4.10 Permanent Installation of fixed Ballast at rear Fuselage

In special cases empty weight C.G. position may be shifted rearward to
allow heavy pilots to fly with rearward in-flight C.G. positions.
Therefore it is possible to install the following ballast at the tail:
a) a battery 3BR-199
b) a heavy tail wheel hub S27
c) a trim weight (drawing 4R8-109) at the vertical fin shear web above the
tail wheel box see sketch 1.
Sketch 1: (Tail wheel box and lower
rudder bearing not drawn).
Washers
B6.4 DIN 9021-Stzn
Nuts
M6 LN 9348 or
M6 DIN985-8zn
(width over flats
10 mm)
Caution: The necessary holder (according to drawing 4R8-107b) is not
installed as standard equipment. It may be installed according to section
4.11.
Never dismount the trim ballast holder because its bolts and nuts are fixing
points for the elevator control system!
Removal and installation of the rudder (see section 1.3). Check for
unobstructed movement of rudder and measure rudder deflections after
work!
After installation of permanent weight at rear fuselage, a new C.G. weighing
must be performed (see section 5).
Maximum weight of trim weight 4R8-109: approx. 2.45 kg <5.5 lbs>.
