1.404 Class deviations. Class deviations affect more than one contract action. When an agency knows that it will require a class deviation on a permanent basis, it should propose a FAR revision, if appropriate. Civilian agencies, other than NASA, must furnish a copy of each approved class deviation to the FAR Secretariat. (a) For civilian agencies except NASA, class deviations may be authorized by agency heads or their designees, unless 1.405 (e) is applicable. Delegation of this authority shall not be made below the head of a contracting activity.
