Flight Crew Human Performance
We were unable to retract the right main landing gear after takeoff; during initial climb out. We stayed in the traffic pattern and lowered the gear normally with a normal indication. We returned to the field with a normal visual approach and there was no further complications. The aircraft was below maximum landing weight by 1000 pounds and never exceeded any limitations. We initially saw a red gear indication on the right main landing gear immediately after takeoff and ATC brought it to our attention shortly afterwards. We stayed in the traffic pattern and did a normal visual approach to a landing. The gear was extended normally with a normal 3 green indication. There was no overweight landing and no limitation exceeded. We had a write-up in the log that our #4 tire was bald and worn. Maintenance came to the airplane to change the tire and installed 1 gear pin in the right main landing gear only. There was never any write-up that a gear pin was either installed or removed during the maintenance procedure. The captain did a visual inspection on the right main after maintenance finished working on the aircraft and missed the flagged gear pin up in the right main. Prior to departing the gate; we ran through the receiving checklist and I looked back seeing the gear pin flaps but didn't count how many were actually on board. I noted that all 4 gear pins were on board as a completed checklist item. Maintenance had failed to note in the log that the gear pin was installed as standard maintenance procedure for changing a tire. The captain missed the gear pin flag on the visual inspection after the maintenance procedure was accomplished. I assumed since seeing gear pin flaps behind the captain's seat that all 4 were there and noted it on the receiving checklist that all 4 were onboard. It was; however; a 15 hour duty day; the last leg of the day; and missed by all 3 people.

Title: EMB145 DISCOVERS AIRBORNE THAT THE RIGHT MLG WAS PINNED BY MAINT FOR A TIRE CHANGE AND NEVER REMOVED.
Narrative: WE WERE UNABLE TO RETRACT THE R MAIN LNDG GEAR AFTER TKOF; DURING INITIAL CLBOUT. WE STAYED IN THE TFC PATTERN AND LOWERED THE GEAR NORMALLY WITH A NORMAL INDICATION. WE RETURNED TO THE FIELD WITH A NORMAL VISUAL APCH AND THERE WAS NO FURTHER COMPLICATIONS. THE ACFT WAS BELOW MAX LNDG WT BY 1000 LBS AND NEVER EXCEEDED ANY LIMITATIONS. WE INITIALLY SAW A RED GEAR INDICATION ON THE R MAIN LNDG GEAR IMMEDIATELY AFTER TKOF AND ATC BROUGHT IT TO OUR ATTN SHORTLY AFTERWARDS. WE STAYED IN THE TFC PATTERN AND DID A NORMAL VISUAL APCH TO A LNDG. THE GEAR WAS EXTENDED NORMALLY WITH A NORMAL 3 GREEN INDICATION. THERE WAS NO OVERWT LNDG AND NO LIMITATION EXCEEDED. WE HAD A WRITE-UP IN THE LOG THAT OUR #4 TIRE WAS BALD AND WORN. MAINT CAME TO THE AIRPLANE TO CHANGE THE TIRE AND INSTALLED 1 GEAR PIN IN THE R MAIN LNDG GEAR ONLY. THERE WAS NEVER ANY WRITE-UP THAT A GEAR PIN WAS EITHER INSTALLED OR REMOVED DURING THE MAINT PROC. THE CAPT DID A VISUAL INSPECTION ON THE R MAIN AFTER MAINT FINISHED WORKING ON THE ACFT AND MISSED THE FLAGGED GEAR PIN UP IN THE R MAIN. PRIOR TO DEPARTING THE GATE; WE RAN THROUGH THE RECEIVING CHKLIST AND I LOOKED BACK SEEING THE GEAR PIN FLAPS BUT DIDN'T COUNT HOW MANY WERE ACTUALLY ON BOARD. I NOTED THAT ALL 4 GEAR PINS WERE ON BOARD AS A COMPLETED CHKLIST ITEM. MAINT HAD FAILED TO NOTE IN THE LOG THAT THE GEAR PIN WAS INSTALLED AS STANDARD MAINT PROC FOR CHANGING A TIRE. THE CAPT MISSED THE GEAR PIN FLAG ON THE VISUAL INSPECTION AFTER THE MAINT PROC WAS ACCOMPLISHED. I ASSUMED SINCE SEEING GEAR PIN FLAPS BEHIND THE CAPT'S SEAT THAT ALL 4 WERE THERE AND NOTED IT ON THE RECEIVING CHKLIST THAT ALL 4 WERE ONBOARD. IT WAS; HOWEVER; A 15 HR DUTY DAY; THE LAST LEG OF THE DAY; AND MISSED BY ALL 3 PEOPLE.
