Flight Manual STEMME S6 3.8.2 Engine-Failure during Take-Off In the case of an engine-failure, or when not enough power is available, perform the following procedure: If RWY is long enough, land straight ahead. If RWY is NOT LONG enough, the pilot has to decide how to proceed, depending on altitude, position and terrain.
Page 58: Engine-Failure During Flight
Flight Manual STEMME S6 3.8.3 Engine-Failure during Flight An engine-failure is possible in all flight-phases and must be considered in flight- planning. Existing experience with the engine shows, that certain engine-failure- situations are more likely than others. The relevant emergency procedures are described in the following section.
Page 59 Flight Manual STEMME S6 Ignition BOTH Starter START (if necessary) If the restart of the engine fails: Prepare for an off-field-landing or a landing on next suitable airfield. Caution: Within 10 seconds after engine-restart, the oil-pressure must be in the green range. If not, a major engine-problem may exist.
Page 60: Drive-Section-Failure
Flight Manual STEMME S6 3.8.4 Drive-Section-Failure In the case of a failure of the drive-section the power-transmission from the engine to the propeller is destroyed.

Page 64: 3.11 Emergency-Landing-Procedures
Flight Manual STEMME S6 3.11 Emergency-Landing-Procedures ___________________ 3.11.1 Off-Field-Landing For an off-field-landing, select the landing-area carefully. Pay great attention to the character of the surface-material in respect of the wheel-load. Landing on soft ground with not enough load-carrying-capacity is connected with a great risk.
Page 65 AIRSPEED. Do not use full air- brakes and be aware of the risk of flipping over. Caution: With its long landing-gear, the S6 has a tendency to flip-over when landing on soft ground. It is recommended to touchdown with MINIMUM AIRSPEED and to pull the elevator full up until standstill.
Page 66 Flight Manual STEMME S6 3.11.2.3 Landing with Damaged Wheel-Brakes Try to land on a grass surface to shorten the ground-roll-distance with roll-resistance. 3.11.2.4 Emergency Landing on water An emergency landing on water has high risks and should be used only as the last option.
Page 67 Flight Manual STEMME S6 Warning: Aircraft with nose-wheels tend to flip-over when landing on water. With the cockpit under water it is almost impossible to open the canopy without pressure-equalization by opening the cabin-ventilation and emergency-window. 3.11.2.5 Landing with Ground-Loop If a collision is not avoidable during the final part of the landing, initiate a ground- loop with enough distance from the obstacle.
Page 68: 3.12 Other Emergencies
Flight Manual STEMME S6 3.12 Other Emergencies ______________________________ 3.12.1 System Malfunctions Warning When a system behaves not normally - make checks as in section 3.12.1.1 through 3.12.1.19. Before the next flight find and eliminate the cause of the system malfunction according to the Maintenance Manual.
Page 69 Flight Manual STEMME S6 When little fuel is available If necessary reduce power- setting and air-speed. Fly without bank-angle or sideslip. If the engine has stopped Do normal airstart-procedure (see section 4.7.3.4) If the fuel-pressure is normal again when using of the auxiliary-fuel-pump (but drops when the auxiliary-fuel-pump were set to OFF) most likely there is a malfunction of the main-fuel-pump or a malfunction of the internal generator.
Page 70 Flight Manual STEMME S6 3.12.1.2 Green Light for Operation of Auxiliary-Fuel-Pump If the green light for the auxiliary-fuel-pump is ON, this is not an emergency. It shows that the auxiliary-fuel-pump is running. If the auxiliary-fuel-pump is set to ON, but with no green light, this can be a malfunction of the auxiliary-fuel-pump or a malfunction of the indication-light.
Page 71 Flight Manual STEMME S6 Fuel Transfer Pump ON until the yellow Low-Fuel- Caution-Light goes OFF and (low fuel in the right main tank) adequate fuel has been transferred into the main-tank. If there is adequate fuel in the right main tank AND the yellow Low-Fuel-...
Page 72 Flight Manual STEMME S6 3.12.1.4 Red MAP-Warning-Light is ON or FLASHING Red MAP-warning-light is continuously ON: The manifold-air-pressure is higher than maximum allowed limit: The manifold-air-pressure is not automatically controlled. In this case, THROTTLE BACK. Control the manifold-air-pressure with throttle (MAP-warning-light must go OFF).
Page 73 Flight Manual STEMME S6 3.12.1.5 Yellow TCU-Caution-Light of Manifold-Air-Pressure-Control is FLASHING A malfunction of the following systems is possible: sensors sensor-lines Turbo-Control-Unit Leakage of airbox CONTROL the RPM and manifold-air-pressure with THROTTLE (red MAP-warning-light must be OFF). Recommended operating limits: ≤ 75% MCP (MAP : ≤...
Page 74 Flight Manual STEMME S6 3.12.1.6 Red External-Alternator-Warning-Light is ON If the red external-alternator-warning-light is ON, this shows that the alternator (with engine-master-switch ON) is not generating electrical power. This is normal if the engine is not running. If the external-alternator-warning-light is ON when the engine is running, this could be a malfunction.
Page 75 Flight Manual STEMME S6 3.12.1.8 Total Electrical Failure A total electrical failure can have several reasons. In any case, the COM and all electrical equipment are not available, including: elevator-trim, propeller pitch control engine-instrumentation, incl. Turbocharger-Control-Unit (TCU) (except manifold-air-pressure-gauge). Also the electrical auxiliary-fuel-pump and the TCU will fail.
Page 76 Flight Manual STEMME S6 3.12.1.9 Loss of Electrical Energy for the Turbo-Control-Unit (TCU) When the TCU has no energy, because of master-switch OFF engine-master-switch OFF or the corresponding circuit-breakers have popped-out. the following procedure is recommended: Turn OFF the waste-gate-actuator with TCU-isolation-switch in the ACTIVATED position (the switch is UP).
Page 77 Flight Manual STEMME S6 3.12.1.10 Sudden Drop of Manifold-Air-Pressure MAP and RPM If the MAP and RPM suddenly drop, together with high noise or a bang, it is most likely that the turbocharger is damaged: SHUT-DOWN the engine as soon as possible. Change to glider- configuration and look for a safe landing-area.
Page 78 Flight Manual STEMME S6 3.12.1.11 Sudden Rise of Manifold-Air-Pressure MAP and RPM If the MAP and RPM suddenly rise and the yellow TCU-caution-light is FLASHING, a malfunction of the turbocharger-control-unit is most likely: Control RPM and MAP with throttle (red MAP-warning-light must be OFF) Recommended operating limits: ≤...
Page 79 Flight Manual STEMME S6 3.12.1.12 Repeating Increase and Decrease of Manifold-Air-Pressure MAP and RPM A periodic increase and decrease of MAP and RPM is most likely caused by oscillations of the manifold-air-pressure-control (while the yellow TCU-caution- light is not flashing). The following procedure is recommended:...
Page 80 Flight Manual STEMME S6 3.12.1.13 Exceeding the Maximum Cylinder-Head-Temperature CHT If the maximum CHT is exceeded, the following procedure is recommended: Cowl-flaps fully OPEN Throttle REDUCE as necessary for safe flight If the CHT does not decrease below maximum, change to glider-...
Page 81 Flight Manual STEMME S6 3.12.1.15 Oil-Pressure below Minimum during Flight If the oil-pressure is below minimum during flight, the following procedure is recommended: If a safe landing can be done in glider-configuration, change to glider- configuration (see section 4.7.3.2) Otherwise REDUCE throttle to the minimum required for a safe flight.
Page 82 Flight Manual STEMME S6 3.12.1.18 Loss of Propeller-Pitch-Control During flight, the pilot must check the RPM continuously. If the RPM changes unintentionally (during flight over a strong electro-magnetic-transmitter or by a malfunction of the pitch-control), the following procedure is recommended: Unintentional pitch-changes, RPM-variation in the „AUTO“-position or...

Page 118: Flights At High Altitude
FLIGHT MANUAL TSA-M, VARIANT S6 4.7.7 Flights at High Altitude The actual air-speed (TAS) at high altitudes is above the indicated air-speed (IAS). There is no restriction to the allowed flight-envelope below FL65 (2000m). Above this altitude, the never-exceed speed v is decreased according to the decrease in air-density.
Page 119: Flights In Rain
FLIGHT MANUAL TSA-M, VARIANT S6 Flying at high altitude can cause ice to form on the airframe. This can cause significant disadvantages in the aerodynamic behavior, aircraft mass and CG- position. A considerable decline of flight performance and behavior is possible.
Page 120: Flights In Strong Turbulence
FLIGHT MANUAL TSA-M, VARIANT S6 Land with FLAPS set to NEUTRAL. The A/C has the tendency to float longer than normal and touch-down with a higher speed. The landing- gear’s directional-stability reduces the A/C’s sensitivity to crosswind during the ground-roll.
Page 121: Flights In Icing-Conditions
FLIGHT MANUAL TSA-M, VARIANT S6 4.7.11 Flights in Icing-Conditions Ice and hoar-frost significantly influence the air-flow around the A/C. The mass will increase and flight performance and behavior will decrease significantly. Avoid flights in icing-conditions. In the case of an unintended flight into an area of icing-conditions, leave the area immediately by turning around or reducing altitude.
