Synopsis
Flight crew reported an air turn back and precautionary landing aft the LG WOW SYS FAIL message was received.
Narrative
Aircraft X had a previous write up and subsequent diversion to ZZZ which was related to 'LG WOW SYS FAIL'. Maintenance performed the necessary repairs while we waited for the airplane to be signed off and released back into service. We were to then ferry the airplane to ZZZ1. After takeoff upon gear retraction; we immediately got the 'LG WOW SYS FAIL' EICAS message. We stopped our climb at 5;000 ft. and requested holding in order to run the QRH procedure. We performed the QRH procedure for 'LG WOW SYS FAIL'; carefully reviewed and applied the special Considerations; and landed without further issue.We deemed requesting priority handling as a necessary safety precaution due to the potential loss of spoilers; reverse thrust; steering capability and priority handling to minimize possibility of go-around as procedure called for a 'gear down' go-around. We requested no further assistance and the steering; stopping and all expectation functionality was effective yielding a safe outcome and no further action required.
Second reporter narrative
Aircraft X had a previous write up which was LG WOW SYS FAIL. Maintenance finished signing this off while we waited. This was a ferry flight from ZZZ to ZZZ1.After takeoff upon gear retraction; we got the LG WOW SYS FAIL EICAS. We held at ZZZ2; ran the QRH procedure and applied the Special Considerations; and landed uneventfully. We requested priority handling due to the potential loss of stopping and steering capability and requested no further assistance. The steering and stopping was effective; and we landed uneventfully back at ZZZ.
