Re:  Exemption Request Pursuant to Section 333 of the FAA Modernization and Reform Act of

2012

Dear Sir or Madam:

AHNTECH, Inc. (“AHNTECH”) requests an exemption from the Federal Aviation Regulations

(“FARs”) listed below to provide commercial surveying, videography, and photography services

using small Unmanned Aircraft Systems (UAS) in airspace regulated by the Federal Aviation

Administration.

AHNTECH is an award‐winning contract provider of technical services serving both commercial

and government customers.   We have significant experience gathering survey data from

operating unmanned ground vehicles, and maintain an excellent safety record.  

The UAS proposed by AHNTECH is the battery‐powered, commercially available DJI Phantom 3,

weighing less than three (3) pounds including battery.  This UAS is substantially similar to the

DJI Phantom 2 Vision+ , which has been granted similar Part 333 exemptions, in terms of size,

weight, and flight capabilities, but has an improved camera system as well as additional sensors

and monitoring software to allow it to safely fly indoors in tight spaces.  For your reference, the

specifications published by the manufacturer for the DJI Phantom 3 are attached as Appendix A.

Granting this exemption would allow AHNTECH to provide aerial data collection services,

namely, land surveying, videography, and photography services to both our existing

government and commercial customers.

   
Name and Address of the Applicant

The name of the applicant is:   

AHNTECH, Inc.

Exemptions Requested

AHNTECH respectfully requests exemptions from the following regulations:

14 CFR 61.23(a) and (c),

14 CFR 61.101(e)(4) and (5),

14 CFR 61.113(a),

14 CFR 61.315(a),

14 CFR 91.7(a),

14 CFR 91.119(c),

14 CFR 91.121,

14 CFR 91.151(a)(1),

14 CFR 91.405(a),

14 CFR 91.407(a)(1),

14 CFR 91.409(a)(1) and (2),

14 CFR and 91.417(a) and (b).

Extent of Relief and Reason

AHNTECH seeks relief for the general purpose of commercial land surveying, aerial

photography, and aerial videography so that these services can be made available to our

commercial and government customers.

While AHNTECH has modeled its request off of Part 333 exemption grants as of the date of this

application, AHNTECH requests that the FAA treat this application as requesting the most

lenient relief granted to similar applications at the time of adjudication.
Benefit to the Public as a Whole

AHNTECH’s aerial surveying, photography, and videography services using small UAS provides a

unique solution to customers who require a high level of detail in their photos and videos at an

angle unavailable from manned aircraft, at significantly less cost and risk to the general public.

Federal Register Summary

The following summary is provided for publication in the Federal Register, should the FAA

determine that publication is needed:

Petitioner:   AHNTECH, Inc.

Section of 14 CFR:  14 CFR §§ 61.23(a) and (c), 61.101(e)(4) and (5), 61.113(a), 61.315(a),

and 91.417(a) and (b).

aerial surveying, photography, and videography services using a small unmanned

aircraft (55 pounds or less) in the national airspace regulated by the FAA.

Respectfully submitted,

Eugene Ahn
