Background

On October 22, 2014, the FAA published a proposed a new chapter of FAA Order 8900.1 and a proposed new AC related to Aircraft Dispatcher Certification Courses. The new chapter in FAA Order 8900.1 chapter establishes Policy not previously addressed in FAA Orders or ACs. The associated AC, 65– XX, provides guidelines to operators and potential operators of Aircraft Dispatcher Certification Courses. On November 06, 2014, Sheffield School of Aeronautics placed a comment in this docket requesting the publication of additional supporting documents which contain policy related to Designated Aircraft Dispatcher Examiners (DADE). Additionally, Sheffield requested the FAA consider extending the comment period, which is scheduled to close on December 22, 2014. In response to these requests, we have extended the comment period for the Aircraft Dispatcher Certification Course Policy contained in this docket for another 60 days to allow additional review by industry stakeholders. We have also made the DADE policy supporting documents available for review only, in their own respective docket, which is FAA–2011–1149. That particular docket, which is not open for comment, can be accessed at the following URL: http://www.regulations.gov/#!docket Detail;D=FAA-2011-1149.

The FAA does not anticipate any further extension of the comment period for the draft policy related to Aircraft Dispatcher Certification Courses, contained in this docket.

The agency will consider all comments received by February 22, 2015. Comments received after that date may be considered if consideration will not delay agency action on the review. A copy of the proposed order and AC is available for review in the assigned docket for the Order at http:// www.regulations.gov.
