Harbin Yunsunji Y-12 | Bureau of Aircraft Accidents Archives

While taxiing at Kuala Lumpur Airport, the pilot applied braked when approaching a right turn when the aircraft veered 90° to the left, rolled through the ramp and eventually collided with a parked Pelangi Air Dornier DO228 registered 9M-PEL. While the DO228 was slightly damaged, the Y12 was written off. All 19 occupants escaped uninjured.

Probable cause:

It was determined that the loss of control occurred after the brakes failed because the pilot did not select the primary hydraulic system.
