Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
$1200 Additional billing amount.

2200.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

The L3 FA2100 may be installed as a retrofit for the mechanical tape-based GA100 CVR. The following part numbers of the FA2100 may be used for this retrofit:


The solid state FA2100 is recommended in place of the tape type GA100 for reliability and long-term maintenance reasons.

The FA2100 GACVR Instruction Manual specifically mentions this retrofit with a few conditions.
  • The GA100 can be powered by either AC or DC, the FA2100 is 28VDC only
  • The GA150 control panel may be retained however it is recommended to replace it with a control panel still in production
  • If the GA100 installation utilizes the A55B microphone, it must be removed and replaced with a S056 model microphone
  • The Test Lamp wire connected to pin 23 must be moved to pin 44 in the CVR mating connector
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.
