Landing and Collision
During an ILS approach to runway 03, the aircraft touched down. Shortly after touchdown, the pilot observed deer on the runway ahead. Before evasive action could be taken, the aircraft collided with two deer. The impact occurred with the left main landing gear, fracturing a hydraulic brake line.
Loss of Brake Pressure and Evasive Maneuver
Following the collision, brake pressure was lost. The pilot steered the aircraft onto the grass off the right side of the runway to avoid overrunning the runway end and descending a hill.
Aircraft Examination and Occupant Status
Examination of the aircraft confirmed that the deer strike damaged the hydraulic brake line. The aircraft's nose gear also collapsed during the landing roll. All nine occupants escaped the incident without injury.
Investigation Findings
The official investigation identified two occurrences. The first was an on-ground/water collision with an object, noting fog as a weather condition and the object being animal(s), with clearance not possible. The second occurrence was a nose gear collapse, attributed to the normal brake system being disabled, brakes unavailable, and the nose gear assembly overloaded.
