FAA Form 7140-1, Notice of Proposed Outdoor Laser Operation(s)
Who Should Complete and Submit This Form
Any person, entity, or proponent who plans to conduct outdoor laser operations with a visible laser
beam exceeding 50 nanowatts per square centimeter in navigable airspace or with any laser beam
(visible or non-visible) that exceeds the maximum permissible exposure in navigable airspace. FAA
encourages proponents to contact the applicable FAA service center for guidance.
Instructions to Complete
Consult FAA Advisory Circular (AC) 70-1 for detailed instructions to assist with completing and
submitting this form. Refer to FAA Order JO 7400.2, Chapter 29 for additional background
information. FAA provides public access to these documents via
https://www.faa.gov/regulations_policies.
Please print or type on this form and complete all sections prior to submission to the appropriate FAA
service center. To enhance clarity, use plain language and numbers, e.g., decimal notation (0.7277)
instead of scientific notation (72.77x10-2 or 72.77E-02). Failure to provide all requested information
may delay processing.
Paperwork Reduction Act Statement
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to
a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act
unless that collection of information displays a currently valid OMB control number. The OMB control number for this
information collection is 2120-0662. Public reporting for this collection of information is estimated to be approximately 240
minutes per response, including the time for reviewing instructions, searching existing data sources, gathering and
maintaining the data needed, completing, and reviewing the collection of information.
The Federal Aviation Administration (FAA) requires all responses to this collection of information if the proponent wishes
to obtain or retain benefits available per Title 21 Code of Federal Regulations Part 1010 if projecting into navigable
airspace. Send comments regarding this burden estimate or any other aspect of this collection of information, including
suggestions for reducing this burden to: Information Collection Clearance Officer, Federal Aviation Administration, 10101
Hillwood Parkway, Fort Worth, TX 76177-1524.
