Thanks for your immediate reply. Tested it and this is, what I found out.
I use the IXEG_Failure script to induce random failures, but it was not active at this flight, therefore I don`t understand that this happened at all.
I could not create the situation again, thus I was not able to test things with gear lever down. With gear lever up, manual extension of the gear does not work. With gear lever in OFF, it works as expected, independent of hydraulic the pressure.
Would have helped to read the complete sentence in the QRH : in the NG manual gear extension can be accomplished with landing gear lever in ANY position. However for standardization with the CL the lever is placed to OFF.
Strange wording, but yes
