On September 26, 2018, the FAA issued a notice of availability; request for comments, entitled “Proposed Primary Category Design Standards; Vertical Aviation Technologies (VAT) Model S-52L Rotorcraft” (83 FR 48574) (“notice of availability”). The notice of availability established a 60-day comment period.

The FAA finds that a 30-day comment period is sufficient for the public to analyze and provide meaningful comment to notice of availability. The date by which to file comments is therefore shortened from November 26, 2018, to October 26, 2018. The FAA does not anticipate any further action to be taken regarding this comment period.

Shortening of Comment Period

Accordingly, the comment period for the notice of availability has been shortened to close on October 26, 2018.
