Technical Standard Order (TSO)-C65a, Airborne Doppler Radar Ground Speed and/or Drift Angle Measuring Equipment (For Air Carrier Aircraft)
This notice announces the FAA's cancellation of TSO-C65a. The effect of the cancelled TSO will result in no new TSO-C65a design or production approvals. However, cancellation will not affect current production of articles with an existing TSO authorization (TSOA). Articles produced under an existing TSOA can still be installed per the existing airworthiness approvals.
