What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Airman advises that he counsels his passengers about how to operate the brakes and also not to touch the red switch, located on the control stick. After engine start, he asked his passenger to test his brakes. The passenger subsequently hit the switch on the control stick which releases all hydraulic and air pressure. This induced a loss of control and braking. (Air brakes are installed on this a/c)the airman cut the mixture and shortly thereafter impacted a cement wall. No injuries were sustained. The propeller is destroyed, and minor damage to the right wingtip, and right side of bottom cowling.
