Analysis

The plt was taxiing from the ramp & attempted to turn left onto a taxiway. The nose gear steering was not sufficient to make the turn, so he applied left brake. However, the left brake did not operate since the master cylinder was void of brake fluid. The acft went off the taxiway onto soft terrain. The plt then applied power to get back onto the taxiway, but the left main gear dropped into a hole & collapsed. The master cylinder o-ring was found to have deteriorated which allowed all of the fluid to leak out.
