4.1 Introduction
Section 4 provides checklists and amplified procedures for the conduct of normal
operation. Normal procedures associated with optional systems can be found in
section 9.
4.2 Rigging and derigging, filling the watertanks, refuelling
4.2.1 Rigging
1. Execute the inspection prior to rigging according to section 4.3 A.
2. Clean and grease all pins and bushes and all 4 automatic control system
connectors.
3. Open the canopy.
4. Set the airbrake handle to the forward stop and control stick and wingflap
handle to neutral.
Always rig inner wings without 15 m or 18 m tips.
With a helper on the wingtip, push the left wing into place, then the right
wing.
Check for correct dihedral. The flaperons should be held at neutral for
rigging, airbrakes locked. All controls will hook up automatically.
Caution: Make sure that the wing trailing edge is at the same height as its
counterpart at the fuselage before the controls hook up. Otherwise a ball bearing
of a control hook up bellcrank (mounted at the wing root) may knock against
the fuselage-side control and will be damaged.
Sight through the wing main pin bushings to determine alignment. Push the
main pins in as far as possible. Turn one handle after the other up to the
fuselage wall, while pulling out the white securing knob, then release the
knob back to its locked position. Check the securing.
5. Insert the wing tip extensions (18 m) into the wing.
Press in the locking pin with your finger.
Insert the wing tip until the flaperon connecting pins start to slide into the
centre-flaperon bushes.
Strike firmly with the palm of your hand on to the wing tip to lock the wing
tip extension.
The rigging of the 15 m wingtips (Option) has to be done in the same
manner as the wing tip extensions.
6. Check if you are safe to fly with the fin battery (see Data Placard in cockpit
or entries in section 6). Insert the battery into place. Connect battery to the
aircraft electric system and check operation.

7. Rigging of the horizontal tailplane
Check the glued joint of the spherical insert in the eye-bolt in the front
horizontal tailplane attachment. Swivel movement is not allowed!
Warning: If this insert is loose, flights are strictly prohibited. Contact the aircraft
manufacturer.
Install the horizontal tailplane and fix it by turning the slotted nut mounted
on the rear attachment (using supplied key or suitable coin) until there is no
more free play and the red marking on the main attachment bracket is no
longer visible via the hole in the upper shell.
8. Install total energy tube, secure against rotating using tape.
9. Mount all necessary equipment in the baggage compartment. Safely secure
all items.
10. Connect automatic parachute ripcord at red marked position at main
bulkhead. Wrap cord around the lift pin tube.
11. Tape the gaps of the wing-fuselage junctions, the wing joints and the
horizontal stabilizer.
12. Execute a positive control check, one helper is needed to hold firmly the
control surfaces.
Only LS10-st
13. Pull off the fuel vent surge bottle from the fuel vent line (bottom side of the
fuselage).
14. Open fuel shut off valve.
4.2.2 De-Rigging:
Derigging follows the reverse of rigging.
Waterballast must be dumped first.
Airbrakes should be locked.
Note: It is also possible to de-rig with the airbrakes not locked. In such case you
have to make sure that the airbrakes won’t be damaged in the trailer in case they
extend due to vibrations. It is not necessary to lock the airbrakes for rigging
Disassembling the wing tips:
Use a 6 mm diameter pin for pressing in the locking pin on the wing’s upper
surface. Pull out the wing tips.
Only LS10-st
Push the fuel vent surge bottle onto the fuel vent line (bottom side of the
fuselage).
Close fuel shut-off valve.
Note: During road-transport with full fuel tank fuel may spill via the carburettors
or via the ventilation line. To avoid this the fuel shut-off valve should be
closed during de-rigging and the fuel vent surge bottle installed.

7.16 Canopy
Canopy emergency release
Canopy locks :pull both red handles to stops
- Right handle operates emergency canopy jettison, therefore
it has longer travel than left handle.
Pull with more than 15kg / 33lbs!
- Hand force increases for emergency jettison travel to avoid
unintentional jettison during normal operation.
Canopy: Push off canopy using both red handles
- The gas strut which lifts the instrument panel assists the
canopy jettison.
LS-latch (Röger hook): This device is installed at the upper rear end of the
canopy and serves as hinge point for the canopy after
emergency release..
Checking the emergency release on the ground and removal of canopy:
One person must sit in the cockpit and one person must hold the canopy at the
front end.
1. With canopy closed pull on both red handles to bring them to the open
position. Thereafter pull strongly on the right hand handle to jettison the
canopy.
2. As soon as the canopy is lifted by the instrument panel support the person
at the front end must hold the canopy so that it will not be lifted more than
approx. 3 cm ( 1 in.).
3. The person in the cockpit must then lift the canopy at the rear end to
disengage the LS-latch (Röger hook).
4. Open the canopy simultaneously with the movement of the instrument
panel.
5. If you want to remove the canopy from the glider disconnect cables, if
equipment like a GPS antenna is installed on the glare shield.
Reinstalling the canopy:
Two people are required to operate and hold the canopy
1. Connect all cables, if equipment like a GPS antenna is installed on the
glareshield
2. Bring the locking lever at the canopy into the open position (rotate
clockwise)
3. Place the canopy on the instrument panel support. Move the locking pin
with the knurled knob (at the instrument panel support) upwards and move
the locking pin through the release cut-out in the canopy. Rotate the
locking lever at the canopy counter-clockwise until the canopy is locked.
Both elements are accessible from the fuselage nose with an open canopy.

Flight Manual LS10-s,-st
Issued: December 2011 TNLS10-027.35
Caution: If you pulled the emergency release inadvertently while opening the
canopy you should hold down the canopy at the emergency release handle.
Then lift the canopy at the rear end with your left hand to disengage the Röger
hook. Then open the canopy simultaneously with the movement of the
instrument panel and take off the canopy. If you don’t follow this procedure
the canopy might be damaged by the instrument panel.
7.17 Miscellaneous equipment (Options)
7.17.1 Removable Ballast
The installation of one trim ballast weight 4R8-108 2.45 kg (5.4 lbs) at the
holder in front of the rudder pedal assy decreases the necessary pilot mass by
approximately 5,5 kg (12 lbs). (max. 3 front trim weights can be
installed).Further data regarding Cockpit Load see section 6.
7.17.2 Oxygen system
A fiberglas receptacle is installed in the left hand side of the main bulkhead for
3 or 4 Litre oxygen bottles of 100 mm (3.94 in) in diameter. Bottles must be
fixed with the designated clamp (P/N.: 4R8-41c)
After permanent installation of an oxygen system according to its
manufacturer instructions by an adequately licensed maintenance/ repair shop,
the sailplane including oxygen system must be inspected (Weight and Balance,
Loading Instructions).
When using a removable oxygen unit, its weight must be counted as cockpit
load.
7.17.3 Emergency Locator Transmitter (ELT)
ELT: The ELT may be installed on the holder 9R96 according to installation
plan 9EP24 attached to the Maintenance Manual and according to the ELT
manufacturer’s instructions.
The designated place is the moulding on the RH side of the landing gear box
below the baggage compartment. As the ELT is not accessible in flight an
ELT remote control must be installed.
The gain access to the on-off switch of the ELT e.g. for switching off the
ELT for ground transport, the radio speaker plate must be mounted on an
access door according to drawing 4R07-091.
Caution: Antenna installation is only certified according to installation plan
9EP22 attached to the MM.
After installation, a functional test and inspection must be performed by a
licensed inspector.
The ELT must be switched off during road transport.
With ELT installed onto holder 9R96, the installation of an additional battery see
AFM sect. 7.17.4 is not possible.
