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.

The FA2100 CVR part numbers 2100-1020-00 and 2100-1020-02 are direct replacements for the A100, A100A (PN 93A100-80, 93A100-83) and A100S (PN S100-0080-00, S100-0080-01) recorders.  No change in aircraft wiring or CVR mounting trays is necessary.  Please reference this L3 Communications document - click Here

Solid State refers to the storage of data in semiconductor memories or integrated circuits. Older technology usually referred to as "tape" technology utilized electromechanical methods of data storage.
Solid State memory does not require scheduled maintenance or overhaul. Therefore, there are potential cost savings to operators and owners. Also data is easier to retrieve and is readily available to for monitoring the performance of the aircraft.
The omnidirectional impact switch model 3RO-434 is recommended. This switch can sense g forces in any direction.
By definition, Frequency-Shift Keying or FSK is a form of frequency modulation in which the modulating signal shifts the output frequency between predetermined values. In relation to aircraft recorders, it is simply a data format that is utilized to input GMT (Greenwich Mean Time). Some recorders are able to either handle GMT via low speed ARINC 429 input or FSK or both.
The Underwater Locator Beacon (ULB) is usually the only part that requires any type of periodic maintenance for most Cockpit Voice Recorders (CVR) and Flight Data Recorders (FDR). This maintenance includes cleaning and testing the ULB every 2 years and replacing the battery every 6 years. It should be noted that some aircraft maintenance programs may include testing and/or bench testing of CVRs or FDRs as part of the aircraft maintenance program.
