Thanks to the quick progress of scrutineering, Wednesday was reserved only for the aforementioned tests. We passed the Rain Test without any complications, but the Brake Test surprisingly slightly troubled us. During this test, it is necessary to lock all 4 wheels at the same time, but we had a problem with locking the rear ones. We took the wheels off and found a small amount of grease on the brake discs. We cleaned everything, degreased it, and after a slight adjustment of the distribution of braking force between the axles, everything went without any problems. Here again, the importance of technical inspections was shown, which can reliably detect these exact problems and guarantee the safety of the pilot and everyone in the vicinity.
