Federal Aviation Administration (FAA), DOT.


Final rule; notice of confirmation of effective date.


This action confirms the effective date of the final rule published on January 3, 2011. The final rule amends the definition of light-sport aircraft by removing “auto” from the term “autofeathering” as it applies to powered gliders. This amendment will allow both manual and autofeathering propeller operation for powered gliders that qualify as light-sport aircraft.


The effective date for the final rule published January 3, 2011, at 76 FR 5, is confirmed as March 4, 2011.

Before publication of this final rule on January 3, 2011 (76 FR 5), Title 14, Code of Federal Regulations (14 CFR) specified that powered gliders that were light-sport aircraft (LSA) had a fixed or autofeathering propeller system. The restriction to “autofeathering” had resulted in confusion to LSA designers. The FAA has determined that a propeller on an LSA powered glider can be safely feathered using either a manual or automatic feathering propeller system, which justifies replacing the term “autofeathering” with “feathering.”

Discussion of the Comments

The FAA received comments from eight individual commenters. All commenters supported the rule change. The commenters generally stated that the rule change removes an unnecessary restriction to the definition of a light-sport aircraft with no adverse safety effect.


After consideration of the comments submitted in response to the final rule, the FAA has determined that no further rulemaking action is necessary. Therefore, Amendment 1-66 remains in effect.
