N813SK, a Bombardier CL-600-2D24 (CRJ900) aircraft operated by SkyWest Airlines, was conducting flight SKW4718 from Winnipeg/James Armstrong Richardson Intl (CYWG), MB to Minneapolis-Saint Paul Intl/Wold-Chamberlain (KMSP), MN. Shortly after the departure from CYWG, the flight crew observed a STEERING INOP caution message, followed by a GEAR DISAGREE warning message.
The flight crew requested vectors while they conducted the QRH procedure for the GEAR DISAGREE. Upon completion of the procedure, the landing gear indicators showed three green lights in the down position. An emergency was declared, and vectors were requested for a low approach so that ATC could visually inspect the landing gear.
The tower reported that the landing gear appeared down, and that the nose wheel was straight. An uneventful landing was then carried out with emergency vehicles standing by. The aircraft was subsequently towed to the gate.
A post-flight inspection by the operator’s maintenance revealed a leaking nose gear strut seal. The seal was replaced and the aircraft was returned to service.
