Dear Mr. Moritz:

This is in reference to your November 7, 2012, petition for exemption from Title 14, Code 

of Federal Regulations (14 CFR) 21.11(b), for approval of electrical wiring interconnection 

systems (EWIS) Instructions for Continued Airworthiness (ICA) and/or assessments.

Upon further review of your petition we note that it requests an exemption from § 26.11(b). 

However, § 26.11(b) is not applicable to Delta Engineering, because § 26.11(b) only applies 

to “Holders of, and applicants for, type certificates,” as identified in paragraph (d) of this 

section. Delta Engineering is neither a holder of, nor an applicant for, a type certificate. 

Therefore § 26.11(b) does apply to Delta Engineering and we cannot process an exemption 

requested based on this fact. 

Therefore, we ask that you withdraw your petition for exemption or modify it to identify

which 14 CFR section from which you wish to seek an exemption. For 14 CFR 26, Subpart 

B- Enhanced Airworthiness Program for Airplane Systems, § 26.11(c) applies to applicants 

seeking either amended or supplemental type certificates. Please submit your withdrawal or 

your modified petition to Department of Transportation’s Federal Docket Management 

System (Docket No. FAA-2012-1209).

If you choose to modify your request, please refer to 14 CFR 11.81 for instructions 

regarding the information you must include in your petition for exemption to allow us to 

process your request. Take particular note of items listed below, as these items were either 

missing or not adequately addressed in your original request.

 The specific sections of 14 CFR from which you seek an exemption.

 The extent of relief you seek and the reasons for seeking the relief.

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

would benefit the public as a whole.

 The reason why granting 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 exemption.

 A summary we can publish in the Federal Register stating the rule from which you 

seek the exemption and a brief description of the nature of the exemption you seek.

You may also want to include the following:

 Any additional information, views, or arguments to support your request, 

and 

 If you want to exercise the privileges of your exemption outside the 

United States, the reason you need to do so.

Section 11.85 requires us to publish a summary of your petitions for exemption in the 

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

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

comment process. 

Also note that § 11.63 requires you to send petitions for exemption at least 120 days before 

you need the exemption to take effect.

We will hold the project open for 30 days awaiting this information. If we do not receive a 

response in 30 days we will close the project with no further correspondence to you.

 

Should you have any questions or concerns regarding your petition or the petition process, 

please contact Stephen Slotte at 425-227-2315, or at steve.slotte@faa.gov.

Sincerely,
