103.1 Applicability.
This part prescribes rules governing the operation of ultralight vehicles
in the United States. For the purposes of this part, an ultralight vehicle
is a vehicle that:
-
(a) Is used or intended to be used for manned operation in the air by
a single occupant;
-
(b) Is used or intended to be used for recreation or sport purposes
only;
-
(c) Does not have any U.S. or foreign airworthiness certificate; and
-
(d) If unpowered, weighs less than 155 pounds; or
-
(e) If powered:
-
(1) Weighs less than 254 pounds empty weight, excluding floats and safety
devices which are intended for deployment in a potentially catastrophic
situation;
-
(2) Has a fuel capacity not exceeding 5 U.S. gallons;
-
(3) Is not capable of more than 55 knots calibrated airspeed at full
power in lever flight; and
-
(4) Has a power-off stall speed which does not exceed 24 knots calibrated
airspeed.
103.3 Inspection requirements.
(a) Any person operating an ultralight vehicle under this part shall,
upon request, allow the Administrator, or his designee, to inspect the
vehicle to determine the applicability of this part.
(b) The pilot or operator of an ultralight vehicle must, upon request
of the Administrator, furnish satisfactory evidence that the vehicle is
subject only to the provisions of this part.
103.5 Waivers.
No person may conduct operations that require a deviation from this
part except under a written waiver issued by the Administrator.
103.7 Certification and Registration.
(a) Notwithstanding any other section pertaining to certification of
aircraft or their parts or equipment, ultralight vehicles and their component
parts and equipment are not required to meet the airworthiness certification
standards specified for aircraft or to have certificates of airworthiness.
(b) Notwithstanding any other section pertaining to airman certification,
operators of ultralight vehicles are not required to meet any aeronautical
knowledge, age or experience requirements to operate those vehicles or
to have airman or medical certificates.
(c) Notwithstanding any other section pertaining to registration
and marking of aircraft, ultralight vehicles are not required to be registered
or to bear markings of any type.
Subpart B - Operating Rules
103.9 Hazardous operations.
(a) No person may operate any ultralight vehicle in a manner that creates
a hazard to other persons or property.
(b) No person may allow an object to be dropped from an ultralight
vehicle if such action creates a hazard to other persons or property.
103.11 Daylight operations.
(a) No person may operate an ultralight vehicle except between the hours
of sunrise and sunset.
(b) Notwithstanding paragraph (a) of this section, ultralight vehicles
may be operated during the twilight periods 30 minutes before official
sunrise and 30 minutes after official sunset or, in Alaska, during the
period of civil twilight as defined in the Air Almanac, if:
(1) The vehicle is equipped with an operating anti collision light
visible for at least 3 statute miles; and
(2) All operations are conducted in uncontrolled airspace.
103.13 Operation near aircraft; right-of-way rules.
(a) Each person operating an ultralight vehicle shall maintain vigilance
so as to see and avoid aircraft and shall yield the right-of-way to all
aircraft.
(b) No person may operate an ultralight vehicle in a manner that
creates a collision hazard with respect to any aircraft.
(c) Powered ultralights shall yield the right-of-way to unpowered
ultralights.
103.15 Operations over congested areas.
No person may operate an ultralight vehicle over any congested area
of a city, town, or settlement, or over any open air assembly of persons.
103.17 Operations in certain airspace.
[No person may operate an ultralight vehicle within Class A, Class B,
Class C, or Class D airspace or within the lateral boundaries of the surface
area of Class E airspace designated for an airport unless that person has
prior authorization from the ATC facility having jurisdiction over that
airspace.]
[(Amdt. 103-4, Eff. 9/16/93)]
EFFECTIVE DATE NOTE: Amdt. 103-4, 56 FR 65662, Dec. 17,
1991, revised Sec. 103.17 effective September 16, 1993. The text of Sec.
130.17 in effect until September 16, 1993 reads as follows:
Sec. 103.17 Operations in certain airspace.
No person may operate an ultralight vehicle within
an airport traffic area, control zone, airport radar service area, terminal
control area, or positive control area unless that person has prior authorization
from the air
traffic control facility having jurisdiction over
that airspace.
[Doc. No. 23708, 50 FR 9259, Mar. 6, 1985]
56 FR 65638, No. 242, Dec. 17, 1991
SUMMARY: This final rule amends the Federal Aviation
Regulations (FAR) to adopt certain recommendations of the National Airspace
Review (NAR) concerning changes to regulations and procedures in regard
to airspace classifications. These changes are intended to:
(1) Simplify airspace designations;
(2) achieve international commonality of airspace
designations;
(3) increase standardization of equipment requirements
for operations in various classifications of airspace; (4) describe appropriate
pilot certificate requirements, visual flight rules (VFR) visibility and
distance from cloud rules, and air traffic services
offered in each class of airspace; and
(5) satisfy the responsibilities of the United States
as a member of the International Civil Aviation Organization (ICAO).
The final rule also amends the requirement for minimum
distance from clouds in certain airspace areas and the requirements for
communications with air traffic control (ATC) in certain airspace areas;
eliminates airport radar service areas (ARSAs), control zones, and terminal
control areas (TCAs) as airspace classifications; and eliminates
the term "airport traffic area." The FAA believes simplified airspace classifications
will reduce existing airspace complexity and thereby enhance safety.
EFFECTIVE DATE: These regulations become effective September
16, 1993, except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605,
71.607, and 71.609 and Part 75 become effective December 12, 1991, and
except that amendatory instruction number 20, Sec. 71.1, is effective as
of December 17, 1991 through September 15, 1993, and that Secs. 71.11 and
71.19 become effective October 15, 1992. The incorporation by reference
of FAA Order 7400.7 in Sec. 71.1 (amendatory instruction number 20) is
approved by the
Director of the Federal Register as of December 17, 1991, through September
15, 1993. The incorporation by reference of FAA Order 7400.9 in Sec. 71.1
(amendatory instruction number 24) is approved by the Director of the Federal
Register as of September 16, 1993 through September 15, 1994.
103.19 Operations in prohibited or restricted areas
No person may operate an ultralight vehicle in prohibited or restricted
areas unless that person has permission from the using or controlling agency,
as appropriate.
103.20 Flight restrictions in the proximity of
certain areas designated by notice to airmen.
No person may operate an ultralight vehicle in areas designated in a
Notice to Airmen under ss91.143 or ss91.141 of this chapter, unless authorized
by ATC.

103.21 Visual reference with the surface.
No person may operate an ultralight vehicle except by visual reference
with the surface.
103.23 Flight visibility and cloud clearance requirements.
[No person may operate an ultralight vehicle when the flight visibility
or distance from clouds is less than that in the table found below. All
operations in Class A, Class B, Class C, and Class D airspace or Class
E airspace designated for an airport must receive prior ATC authorization
as required in ss103.17 of this part.
