Why automatic propellerbrake doesn’t work in DG Flugzeugbau Aircrafts?
- R
  Rachel JonesAug 17, 2025
  If the automatic propeller brake of your DG Flugzeugbau Aircrafts isn't working, it could be due to a worn brake pad causing the brake motor lever to reach its stop. In this case, adjust the brake cable or install a new brake pad, following the instructions in maintenance manual section 1.11.9. Alternatively, the brake motor itself might be defective, along with the proximity switch, DEI-NT, control unit, or wiring.

What causes ignition problems in DG Flugzeugbau Aircrafts?
- L
  Lauren SteeleAug 21, 2025
  If you're experiencing ignition problems with your DG Flugzeugbau Aircrafts, consider these potential causes and solutions: * **No spark on one spark plug of one ignition circuit:** The spark plug, ignition cable, or electronic box may be defective. * **No spark on both spark plugs of one ignition circuit:** This could be due to too low starting RPM, a weak battery, a shorting cable or ignition switch with a ground connection, or a defective electronic box. * **No spark on any of the spark plugs:** Possible reasons include too low starting RPM, a weak battery, a shorting cable or ignition switch with a ground connection, or a defective cable.

What to do if the engine doesn't reach ground test RPM in DG Flugzeugbau Aircrafts?
- C
  Colleen HowardNov 13, 2025
  If the engine of your DG Flugzeugbau Aircrafts doesn't reach ground test RPM, the issue could stem from several causes. The most common reason is a carburettor needle valve that isn't completely shutting off. To address this, disassemble the needle valve (refer to maintenance manual section 1.13.7, item 1), switch on the ignition to allow a fuel jet to clean the valve seat, and then reassemble the needle valve. Other potential causes include dirt in the main nozzle (see maintenance manual section 1.13.7, item 2), a dirty fuel filter (replace or clean it), a throttle butterfly valve that isn't fully opening (lubricate or replace the Bowden cable), faulty ignition (see item 7), clogged or kinked fuel lines (check fuel flow rate as described in maintenance manual section 1.13.3), a need to ex...
