FAA Form 7140-1, Notice of Proposed Outdoor Laser Operation(s)
Who Should Complete and Submit This Form
Any person, entity, or proponent planning to conduct outdoor laser operations with a
visible laser beam exceeding 50 nanowatts per square centimeter or with a
(visible or non-visible) laser beam 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. Reference 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
