14 C.F.R. Part 21, Subpart H: Airworthiness Certificates 14 C.F.R. §91.203 (a) (1)

Subpart H, entitled Airworthiness Certificates, establishes the procedural requirements for the issuance of airworthiness 

certificates as required by FAR §91.203 (a) (1). Given the size and limited operating area associated with the aircraft to be utilized 

by the Applicant, an exemption from Part 21 Subpart H meets the requirements of an equivalent level of safety under Part 11 and 

Section 333 of the Reform Act. The Federal Aviation Act (49 U.S.C.§44701 (f)) and Section 333 of the Reform Act both authorize 

the FAA to exempt aircraft from the requirement for an airworthiness certificate, upon consideration of the size, weight, speed, 

operational capability, and proximity to airports and populated areas of the particular UAS. In all cases, an analysis of these 

criteria demonstrates that the UAS operated without an airworthiness certificate, in the restricted environment and under the

conditions proposed will be at least as safe, or safer, than a conventional aircraft (fixed wing or rotorcraft) operating with an 

airworthiness certificate without the restrictions and conditions proposed.

The UAS to be operated hereunder is less than 55 lbs, fully loaded, carries neither a pilot nor passenger, carries no explosive 

materials or flammable liquid fuels, and operates exclusively within a secured and designated area. Unlike other civil aircraft, 

operations under this exemption will be tightly controlled and monitored by both the operator and under the requirements and in 

compliance with local public safety requirements. These safety enhancements provide a greater degree of safety to the public and 

property owners than conventional operations conducted with airworthiness certificates issued under 14 C.F.R. Part 21, Subpart 

H. Lastly, application of these same criteria demonstrates that there is no credible threat to national security posed by the UAS, 

due to its size, speed of operation, location of operation, lack of explosive materials or flammable liquid fuels, and inability to 

carry a substantial external load.

14 C.F.R. § 45.23 (b). Marking of the Aircraft

The regulation requires: When marks include only the Roman capital letter "N" and the registration number is displayed on 

limited, restricted or light-sport category aircraft or experimental or provisionally certificated aircraft, the operator must also 

display on that aircraft near each entrance to the cabin, cockpit, or pilot station, in letters not less than 2 inches nor more than 6 

inches high, the words "limited," "restricted," "light-sport," "experimental," or "provisional," as applicable.

Even though the UAS will have no airworthiness certificate, an exemption will be needed as the UAS will have no entrance to the 

cabin, cockpit or pilot station on which the word “Experimental” can be placed.

Given the size of the UAS, two-inch lettering will be impossible. The word “Experimental” will be placed on the fuselage in 

compliance with §45.29 (f).

The equivalent level of safety will be provided by having the UAS marked on its fuselage as required by §45.29 (f) where the pilot, 

observer and others working with the UAS will see the identification of the UAS as “Experimental.”

14 C.F.R. § 61.113 (a) and (b): Private Pilot Privileges and Limitations: Pilot in Command.

Pursuant to 14 CFR 61.113 (a) & (b), no person who holds a private pilot certificate may act as a pilot in command of an aircraft 

that is carrying passengers or property for compensation or hire. 

An equivalent level of safety can be achieved by current Regulations because the applicant’s UAS do not carry any pilots or 

passengers nor property. The risks attendant to the operation of UAS is far less than the risk levels inherent in the commercial 

activities outlined in 14 CFR 61. The operation and limitations set forth in the FOM will equate to the safe operation of the UAS.

14 C.F.R. §91.7(a): Civil Aircraft Airworthiness.

The regulation requires that no person may operate a civil aircraft unless it is in airworthy condition. As there will be no 

airworthiness certificate issued for the aircraft, should this exemption be granted, no FAA regulatory standard will exist for 

determining airworthiness.

Given the size of the aircraft for maintenance and use of safety check lists prior to each flight, an equivalent level of safety will be 

provided.

14 C.F.R. § 91.9 (b) (2): Civil Aircraft Flight Manual in the Aircraft.

Section 91.9 (b) (2) provides: No person may operate a U.S.-registered civil aircraft ... (2) For which an Airplane or Rotorcraft Flight 

Manual is not required by §21.5 of this chapter, unless there is available in the aircraft a current approved airplane or Rotorcraft 

Flight Manual, approved manual material, markings, and placards, or any combination thereof. The UAS, given its size and 

configuration has no ability or place to carry such a flight manual on the aircraft, not only because there is no pilot on board, but 

because there is no room or capacity to carry such an item on the aircraft. The equivalent level of safety will be maintained by 

keeping the flight manual at the ground control point where the pilot flying the UAS will have immediate

access to it.

14 C.F.R. § 91.103: Preflight Action.
IowAerial, LLC Petition for Exemption Filed under Section 333

6

This regulation requires each pilot in command to take certain actions before flight to insure the safety of flight. As FAA approved 

rotorcraft flight manuals will not be provided for the aircraft an exemption will be needed. The PIC will take all actions as stated in 

the manufacturer FOM in the pre-flight inspection section, including but not limited to reviewing weather, flight battery 

requirements, landing and takeoff distances and aircraft performance data before initiation of flight.

14 C.F.R. §91.105: Flight crew members at stations

Exemption may be required, the PIC may not leave his station nor shall VO leave station . In event that PIC or VO become 

incapacitated, UAS is to automatically return to designated landing area, as outlined in FOM.

14 C.F.R. §91.109: Flight Instruction.

Section 91.103 provides that no person may operate a civil aircraft (except a manned free balloon) that is being used for flight 

instruction unless that aircraft has fully functioning dual controls. UAS and remotely piloted aircraft, by their design do not have 

fully functional dual controls. Flight control is accomplished through the use of a control box that communicates with the aircraft 

via radio communications. The FAA has approved exemptions for flight training without fully functional dual controls for a number 

of aircraft and for flight instruction in experimental aircraft. The equivalent level of safety provided by the fact that neither a pilot 

nor passengers will be carried in the aircraft and by the size and speed of the aircraft.

14 C.F.R. §91.119: Minimum Safe Altitudes.

Section 91.119 establishes safe altitudes for operation of civil aircraft. Section 91.119 (d) allows helicopters to be operated at less 

than the minimums prescribed, provided the person operating the helicopter complies with any route or altitudes prescribed for 

helicopters by the FAA. As this exemption is for a UAS that is a helicopter and the exemption requests authority to operate at 

altitudes up to 400 AGL, or not more than 200 above an elevated platform from which filming is planned, an exemption may be 

needed to allow such operations. As set forth herein, the UAS will never operate at higher than 400 AGL with the exception that in 

circumstances where the UAS is used to survey or photograph a structure whose height exceeds 400 feet AGL, the UAS will not be 

operated more than 200 feet above the highest point on the structure. It will however be operated in a restricted area with 

security perimeter, where buildings and people will not be exposed to operations without their pre-obtained consent.

The equivalent level of safety will be achieved given the size, weight, speed of the UAS as well as the location where it is operated. 

No flight will be taken without the permission of the property owner or local officials. Because of the advance notice to the 

property owner and participants in the filming activity, all affected individuals will be aware of the planned flight operations. 

Compared to flight operations with aircraft or rotorcraft weighting far more than the maximum 55lbs. proposed herein and the 

lack of flammable fuel, any risk associated with these operations is far less than those presently presented with conventional 

aircraft operating at or below 500 AGL. In addition, the low-altitude operations of the UAS will ensure separation between these 

UAS operations and the operations of conventional aircraft that must comply with Section 91.119.

14 C.F.R. §91.121 Altimeter Settings.

This regulation requires each person operating an aircraft to maintain cruising altitude by reference to an altimeter that is set 

“...to the elevation of the departure airport or an appropriate altimeter setting available before departure.” As the UAS may not 

have a barometric altimeter, but instead a GPS altitude read out, an exemption may be needed. An equivalent level of safety will 

be achieved by the operator, pursuant to the safety check list and live flight data monitoring, confirming the altitude of the launch 

site shown on the GPS altitude indicator before flight.

14 C.F.R. § 91.151(a): Fuel Requirements for Flight in VFR Conditions

Section 91.151 (a) prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind 

and forecast weather conditions) there is enough fuel to fly to the first point of intended landing, and, assuming normal cruising 

speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.”

The battery powering the UAS provides approximately 25 minutes of powered flight. To meet the 30 minute reserve requirement 

in 14 CFR §91.151, UAS flights would be limited to approximately 10 minutes in length. Given the limitations on the UAS’s 

proposed flight area and the location of its proposed operations within a predetermined area, a longer time frame for flight in 

daylight or twilight VFR conditions is reasonable.

Applicant believes that an exemption from 14 CFR §91.151(a) falls within the scope of prior exemptions. Operating the UAS, in a 

tightly controlled area where only people and property owners or official representatives who have signed waivers will be 

allowed, with less than 30 minutes of reserve fuel, does not engender the type of risks that Section 91.151(a) was intended to 

alleviate given the size and speed of the small UAS. Additionally, limiting UAS flights to 10 minutes would greatly reduce the utility 

for which the exemption will be granted. Applicant believes that an equivalent level of safety can be achieved by limiting flights to 

20 minutes or 25% of battery power— whichever happens first. This restriction would be more than adequate to return the UAS 

to its planned landing zone from anywhere in its limited operating area.

14 C.F.R. §91.203 (a) and (b): Carrying Civil Aircraft Certification and Registration

The regulation provides in pertinent part: 

(a) Except as provided in § 91.715, no person may operate a civil aircraft unless it has within it the following:

(1) An appropriate and current airworthiness certificate. . . .

(b) No person may operate a civil aircraft unless the airworthiness certificate required by paragraph (a) of this section or a 

special flight authorization issued under §91.715 is displayed at the cabin or cockpit entrance so that it is legible to 

passengers or crew.

The UAS fully loaded weighs no more than 55 lbs. and is operated without an onboard pilot. As such, there is no ability or place to 

carry certification and registration documents or to display them on the UAS.

An equivalent level of safety will be achieved by keeping these documents at the ground control point where

the pilot flying the UAS will have immediate access to them; to the extent they are applicable to the UAS.

14 C.F.R. §91.405 (a); 407 (a) (1); 409 (a) (2); 417(a) & (b): Maintenance Inspections.

These regulations require that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this 

part and shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repaired as 

prescribed in part 43 of this chapter...,” and others shall inspect or maintain the aircraft in compliance with Part 43.

Given that these section and Part 43 apply only to aircraft with an airworthiness certificate, these sections will not apply to the 

applicant. Maintenance will be accomplished by the operator pursuant to the flight manual and operating handbook. An 

equivalent level of safety will be achieved because the UAS is very limited in size and will carry a small payload and operate only in 

restricted areas for a limited period of time. If mechanical issues arise the UAS can land immediately and will be usually operating 

from no higher than 400 feet AGL. The operator will ensure that the UAS is in working order prior to initiating flight, perform 

required maintenance, and keep a log of any maintenance performed. Moreover, the operator is the person most familiar with 

the aircraft and best suited to maintain the aircraft in an airworthy condition to provide the equivalent level of safety.
IowAerial, LLC Petition for Exemption Filed under Section 333

An equivalent level of safety will be achieved because maintenance and inspections will be performed in accordance with the UAS 

Manufacturer's User Manual. As provided in the FOM, the operator will ensure that the UAS is in working order prior to initiating 

flight and perform required maintenance needed.
