Synopsis
EMB-175 flight crew reported the nose gear pin was not removed before takeoff. The crew received a gear warning during climbout requiring in a return to the departure airport.
Narrative
On departure off [Runway] XXL the pilot flying (FO) called for gear up. I retracted the landing gear. A moment later the master warning chimed. I identified and cancelled the message which was LG lever disagree. We were handed off from Tower to Departure where I notified them of a landing gear issue and requested to come back to the field. We ran the QRH which was unsuccessful in resolving the issue. The nose gear indication on the EICAS was red and down. When we lowered the gear we had down three green so we left the gear down. We [requested priority handling] and were vectored around to return and land. The landing was successful. After we parked back at the gate the FO did the post flight walk around and noted the nose gear pin was inserted in the gear. I wrote up the LG NO DISPATCH ECIAS message in the book and contacted Maintenance about the issue. We were assigned another aircraft and completed to flight without further incident.Suggestions: I could do a quick check myself when entering the flight deck to verify 3 gear pins and one rat pin.
Second reporter narrative
Upon departing from ZZZ and selecting the gear lever up; we were faced with a warning message regarding a gear lever disagree for the nose gear. The mains had retracted normally but the nose gear was stuck in the down position. The Captain appropriately [requested priority handling] and we safely returned to ZZZ. Upon completing a post flight walk around I determined the gear pin was still in the nose gear with the red remove before flight" flag missing. I had previously removed the two main gear pins during my initial walk around but did not see the nose gear pin as I inspected the area. During the originating/receiving checklist I looked over at the area where they are normally stored and thought I saw all pins in their place but was mistaken. I sincerely apologize for the disruption this event caused and will most certainly make a learning experience of it."
