Narrative:
Following a r-hand main gear dual tire change; the gear down-lock pin was inadvertently left installed; resulting in an air turn-back after the r-hand landing gear failed to retract after departing ZZZ. Note: the red flag attached to the pin was dirty/greasy and not very visible. The down-lock pin was missed by 2 mechanics -- the pilot during his preflight; and the FAA flight inspector (check ride in progress). The work card associated with the tire change instructed to install the down-lock pins; but not to remove them. The job was interrupted due to a shift turn-over. We had to leave the work site to switch vehicles; then return to complete the job.
