Many of the discrepancies between the current proposal and the earlier NPRM resulted from the previous proposal to equate a mechanic certificate to an aviation maintenance technician (AMT) certificate. As a result of the completion of the second phase of this review, the FAA proposes the creation of AMT and AMT(T) certificates. The current mechanic certificate with airframe and powerplant ratings would be equivalent to the proposed AMT(T) certificate with an aircraft rating (with no loss of privileges) and not the AMT certificate, as stated in the earlier NPRM. The original proposal to change the term ``mechanic'' to ``aviation maintenance technician'' has, therefore, been modified to reflect the proposed change. All privileges granted to an AMT(T) with an aircraft rating, as set forth in this notice, would apply to the holder of a current mechanic certificate with airframe and powerplant ratings. The holder of the proposed AMT certificate with an aircraft rating would not possess the full approval for return-to-service privileges of the holder of either the current mechanic certificate with an airframe and powerplant rating or the proposed (and equivalent) AMT(T) certificate with an aircraft rating.
