MAP052 – Cockpit Voice Recorder Replacement

The modification covers the replacement of an old L-3-A100S CVR with a new L-3-FA2100 CVR due to obsolescence issues. EASA PART OPS requires the recording of NR (rotor speed) in case there is no Flight Data Recorder (FDR) on board. The L-3-FA2100 CVR has a functionality enabling this recording to be made without the encoder that was previously used with the L-3-A100S CVR.

The modification includes (customer documents):

  • Mechanical installation drawings
  • Wiring diagrams
  • Engineering order
  • Instruction for Continued Airworthiness
  • Flight Manual Supplement
