In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

"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.
