What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Lost brakes landing. Failed to use emergency braking. Lost control. Veered off runway down embankment. (-23) the aircraft was landing on a 3909' runway. The pilot stated that they used normal thrust reverse and spoilers. When the pilot tried the normal brake system it did not work. The other pilot tried brakes on right side and the normal brake system did not work. The aircraft departed the runway on the left side about 1000' prior to the end of the runway. The aircraft came to a stop at the end of the approach lights after going down a steep slope and back up the opposite side. No one on board was injured. Aircraft damage was to the cabin, landing gear, wing spars, and engines. Due to the damage to the pressure vessel that required major repairs, NTSB declared this to be an accident. The brake system components were removed for testing. Results of those tests not available.
