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.

No, an STC is not required for TAS (Traffic Awareness) and/or TCAS I installations on Part 91 and Part 135 aircraft. FAA order 8900.1 provides guidance for a follow on field approval by the FAA. An FAA approved Aircraft Flight Manual Supplement is required as well.
