Probable Cause:SIGNIFICANT FACTORS:
1. The aircraft struck a 10 kg wedge-tailed eagle.
2. The left engine instrumentation failed and the master caution panel indicated multiple system failures.
3. System redundancy was compromised when the wiring was damaged, resulting in the failure of the left weight-on-wheels signal to the proximity switch electronic unit.
4. The nosewheel steering, anti-skid and normal braking, and ground spoiler deployment systems were rendered inoperative.
5. The crew did not follow company procedures by not using checklists to resolve non-normal situations.
