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, Sandel has recently released a service bulletin addressing this issue. The problem has been traced to improper manufacturing tolerances used in the installation of a plastic polarizer in optical system, which does not meet published specifications. Sandel has stated that this problem does not present a flight safety concern and that it is only a cosmetic defect. This service bulletin applies to all serial numbers, shipped prior to August 24, 2009.

A glass polarizer has been designed as a replacement that does not the present the discoloration problem. This part can be retrofitted by the factory into any LED backlit unit.

Identical service bulletins on this problem have also been issued for the SA4550, SN4500 and the SN3500.

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).
Sandel has introduced Reversionary Attitude for the SN3500 and SN4500 Primary Navigation Displays. With this new safety feature, you can call up an attitude display on the SN3500/SN4500 at the flip of a switch while retaining heading and navigational information. Attitude information is provided by Sandel's solid-state SG120 AHRS.

The Reversionary Attitude feature is now available for the SN3500 and SN4500. Upgrade requires a Sandel SG102 or other suitable AHRS. SN3500 units with serial number below 2000 will require an upgrade to LED backlighting.
