Check the listing for details. Bendix Aircraft Digital Central Air Data Digital Computer P/N 3757183-2. Condition: Used. Listed at 250.00 USD. This is a central air data digital computer unit used in Boeing 747 aircraft and possibly other types as well. This one was rewmoved during tear down and has been in storage since. It is in good condition without damage to the connector or housing. The ports are also undamaged, the LED's are not cracked and the controls are all in place and move easily. The data plate is pictured in the final photo. Unfortunately it is not tagged and I have no way to test it so listing it AS IS. Thank you for looking and please see our many other aviation auctions.
