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.

Similar to other manufacturers, the ordering or catalog part number is different than the part number actually printed on the physical unit. Sandel uses a numbering scheme for ordering new systems that begins with 5 numbers (ex. 90131). However, this part number is not on the actual dataplate of the unit. The part number on the unit will usually be similar to the model number with numbers following it (ex. ST3400-000).
