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.

Yes. Southeast Aerospace recommends that Service bulletin 1 and 2 be complied with on the KA-120 when the adapter is being installed on a new installation.

Service Bulletin 1 corrects an impedance mismatch between the new generation KX-155 and KX-165 Nav/Comms that utilize surface mount technology. KA-120 with serial number 1845 and above have Service Bulletin 1 incorporated during original manufacturing. The cost to add SB 1 is approximately $200.

Service Bulletin 2 corrects a serial tuning bus incompatibility when interfacing the KA-120 with a KX-125 and with new generation KX-155 and KX-165 surface mount units (post Mod 16 units). KA-120 with serial number 2819 and above have Service Bulletin 2 incorporated during original manufacturing. Honeywell does offer warranty credit for any KA-120 S/N 2818 and below that requires this modification. An authorized Honeywell Service Center must perform the modification and submit the warranty claim.
