Dear Mr. John B.: 

Small Airplane Directorate 

90 I Locust Street 

Kansas City, Missouri 64106 

This letter is to infonn you that we are unable to process your request for an exemption for a 

heavy ultralight (UL), a 1 0-gallon gas tank, and a new window for heavy ULs that missed the 

previous Light Sport Aircraft (LSA) registration window. It explains why we cannot process 

your request and what you should do in the next 30 days. 

Why We Can Not Process Your Request 

We entered your February 10, 2016, exemption request on behalfofyourselfinto the public 

docket (No. F AA-20 16-3 776), but we are unable to process your request any further. The 

infonnation you sent does not comply with the requirements ofTitle 14, Code of Federal 

Regulations (14 CFR) 11.81 (copy enclosed). For us to consider the request any further, you 

must send us all of the following: 

• Your name and mailing address. 

• The specific section or sections [i.e., § 21.191 (i)( 1) and § I 03.1 ( e )(2)] of 14 CFR from 

which you seek relief, the extent of the relief you seek, and the reason you seek relief. 

• The reasons why granting the request would be in the public interest; that is, how it would 

benefit the public as a whole. 

• The reasons why the exemption would not adversely affect safety or how the exemption 

would provide a level of safety at least equal to that provided by the rule from which you 

seek an exemption. 

• Any additional infonnation, views, or arguments available to support your request. 

For more detailed information relating to submitting petitions for exemption, please visit 

http://aes.faa.gov/petition/index.html. This website helps the petitioner to meet Federal

Additional Information 

Jn regards to your request for a new LSA registration window, the FAA does not intend to 

extend the January 31, 2008 date identified in 14 CFR 21.191 (i)( 1 ). The FAA has denied five 

petitions for exemptions to § 21.191 (i)( I) (Exemption Nos. 8780, l 0026, l 0125, l 0170, and 

l 0171) since January 3 I, 2008. The intent of§ 21.19 1 (i)( 1) was to allow an adequate number 

of experimental light-sport aircraft (ELSA) and instructors to conduct light- sport pilot 

training for the '·transitioning" community until such time that special light-sport aircraft 

(SLSA) were available for this purpose. The FAA has addressed and closed the need for any 

further "transitioning" of ELSA. 

What You Should Do 

If you want us to process your request any further, you must send the information described 

earlier to reach us within 30 days. Please note that 14 CFR 11.63(d) requires you to send your 

petition for exemption at least 120 days before the proposed effective date of the exemption. 

If We Do Not Hear From You 

If we do not hear from you within 30 days, we will close the docket without notifying you 

further. If you have any questions or require additional time, you may contact Mr. Terry 

Chasteen, Light-Sport Aircraft Program Manager at (8 16) 329-414 7 or via email at 

terry. chasteen@faa. gov. 

Sincerely, 

Pat Mullen
