Sole Source - Contractor Engineering Technical Services (CETS)

USAF acquires CETS for highly specialized, on-site, technical services that are essential to accomplishing the assigned missions of the weapon systems identified above. CETS contracts provide a vehicle through which the OEMs can share up-to-date technical information and training to using Commands regarding the operation and maintenance of these weapon systems as they mature or are modified.
AF Engineering and Technical Services (AFETS) field engineers are intended to be the primary source of ETS support in the AF. CETS engineers are an important element in developing an organic ETS capability for USAF systems. In accordance with AFI 21-101, CETS personnel may not be retained on contract beyond which time AFETS personnel have attained proficiency on assigned systems and can provide the technical assistance associated with CETS support. USAF operational units have not achieved this level of proficiency for any of the existing or planned CETS requirements.
