"As Removed" or condition "AR" parts are in the same condition as they were removed from an aircraft. The reasons for removal include aircraft upgrades, teardowns, or certain types of incidents. In most cases, AR parts have not been inspected or tested. They do not include airworthiness certification such as FAA Form 8130 or EASA Form 1. Southeast Aerospace encourages avionics in this condition to be tested and recertified before using in an aircraft.
