we can process it. 

Your request, which was submitted to the Department of Transportation's Federal

office when you provide all necessary information. Please refer to 14 CFR 11.81 for 

instructions about what information you must include in your petition for exemption for us

you seek; and any additional information, views or arguments available to support 

your request. 

You may view public sites to look at previously granted exemptions on the same subject to 

see what public interest justification was used. 

Section 11,85 requires us to publish a summary of your petitions for exemption in the 

Federal Repistey for public comment. Section 11.87 allows you to present reasons, or the 

F AA to find good cause, why we should not delay action on your petitions by the public
