SUMMARY: This action modifies the Houston, TX, Class B airspace area.
Specifically, this action reconfigures two existing subarea boundaries
and establishes an additional subarea within the Houston Class B
airspace area. The FAA is taking this action to enhance safety, reduce
the potential for midair collision, and to improve management of air
traffic operations into, out of, and through the Houston Class B
airspace area while accommodating the concerns of airspace users.
Additionally, the graphic that accompanied the notice proposing this
action inadvertently depicted several incorrect mileage points. This
action corrects those errors.
EFFECTIVE DATE: 0901 UTC, February 26, 1998.

SUPPLEMENTARY INFORMATION:
Background
On December 17, 1991, the FAA published the Airspace
Reclassification Final Rule (56 FR 65655). This rule discontinued the
use of the term ``Terminal Control Area'' and replaced it with the
designation ``Class B airspace area.'' This change in terminology is
reflected in this final rule.
The Class B airspace area program was developed to reduce the
potential for midair collision in the congested airspace surrounding
airports with high density air traffic by providing an area wherein all
aircraft are subject to certain operating rules and equipment
requirements.
The density of traffic and the type of operations being conducted
in the airspace surrounding major terminals increases the probability
of midair collisions. In 1970, an extensive study found that the
majority of midair collisions occurred between a general aviation (GA)
aircraft and an air carrier or military aircraft, or another GA
aircraft. The basic causal factor common to these conflicts was the mix
of aircraft operating under visual flight rules (VFR) and aircraft
operating under instrument flight rules (IFR). Class B airspace areas
provide a method to accommodate the increasing number of IFR and VFR
operations. The regulatory requirements of Class B airspace areas
afford the greatest protection for the greatest number of people by
giving air traffic control (ATC) increased capability to provide
aircraft separation service, thereby minimizing the mix of controlled
and uncontrolled aircraft.
On May 21, 1970, the FAA published the Designation of Federal
Airways, Controlled Airspace, and Reporting Points Final Rule (35 FR
7782). This rule provided for the establishment of Class B airspace
areas. To date, the FAA has established a total of 29 Class B airspace
areas.
The standard configuration of a Class B airspace area contains
three concentric circles centered on the primary airport extending to
10, 20, and 30 nautical miles (NM), respectively. The standard vertical
limit of a Class B airspace area normally should not exceed 10,000 feet
mean sea level (MSL), with the floor established at the surface in the
inner area and at levels appropriate for the containment of operations
in the outer areas. Variations of these criteria may be utilized
contingent on the terrain, adjacent regulatory airspace, and factors
unique to the terminal area.
The coordinates in this docket are based on North American Datum
83. Class B airspace areas are published in paragraph 3000 of FAA Order
7400.9E, dated September 10, 1997, and effective September 16, 1997
which is incorporated by reference in 14 CFR 71.1. The Class B airspace
area listed in this document will be published subsequently in the
Order.
Related Rulemaking Actions
On June 21, 1988, the FAA published the Transponder with Automatic
Altitude Reporting Capability Requirement Final Rule (53 FR 23356).
This rule requires all aircraft to have an altitude encoding
transponder when operating within 30 NM of any designated Class B
airspace primary airport from the surface up to 10,000 feet MSL. This
rule excluded those aircraft that were not originally certificated with
an engine driven electrical system, (or those that have not
subsequently been certified with such a system), balloons, or gliders.
On October 14, 1988, the FAA published the Terminal Control Area
(TCA) Classification and TCA Pilot and Navigation Equipment
Requirements Final Rule (53 FR 40318). This rule, in part, requires the
pilot-in-command of a civil aircraft operating within a Class B
airspace area to hold at least a private pilot certificate, except for
a student pilot who has received certain documented training.
Public Input
In June 1992, an ad hoc committee was formed, representing airspace
users, to analyze the Houston Class B airspace area and develop
recommendations for modifying the existing airspace design. The ad hoc
committee met on several occasions and submitted written
recommendations for modifying the Houston Class B airspace area.
As announced in the Federal Register on January 28, 1994 (59 FR
4134), a pre-NPRM informal airspace meeting was held on April 19, 1994,
in Pasadena, TX, to provide local airspace users an opportunity to
present input on the design of the planned modifications of the Houston
Class B airspace area.
On October 30, 1997, the FAA published an NPRM (62 FR 58694) that
proposed to modify the Houston, TX, Class B airspace area. Interested
parties were invited to participate in this rulemaking effort by
submitting comments on the proposal to the FAA. In response to this
NPRM, the FAA received one comment from the Chapter 712 Experimental
Aircraft Association. This comment supported the proposal.
The Rule
This amendment to 14 CFR part 71 (part 71) modifies the Houston
Class B airspace area. Specifically, this action reconfigures subarea
A, expands subarea D, and establishes an additional subarea E southwest
of the William P. Hobby Airport within the existing Houston Class B
airspace area. The FAA is taking this action to enhance safety, reduce
the potential for midair collision, and to improve management of air
traffic operations into, out of, and through the Houston Class B
airspace area while accommodating the concerns of airspace users.
This action realigns a portion of the eastern boundary of subarea D
where it intersects I-10 in the vicinity of Bayton Airport and R.W.J.
Airpark, by extending the boundary along the Humble VORTAC 30 NM arc
until it intercepts the 20 NM arc of the Hobby VOR/DME. The 4,000 feet
MSL floor of subarea D allows nonparticipating aircraft ingress and
egress out of the Bayton Airport and R.W.J. Airpark.
Additionally, this action reconfigures a portion of subarea A
around William P. Hobby Airport by reconfiguring its eastern boundary.
This modification provides aircraft operators utilizing Ellington
Airport approximately 1 \1/2\-miles of additional airspace for aircraft
operations west of Ellington Airport.
This action also creates a new subarea E in the vicinity of
Southwest Airport with a floor of 2,500 feet MSL. This modification
provides additional airspace for nonparticipating aircraft operating
below the floor of the Houston Class B airspace area.

The graphic included in the NPRM inadvertently depicted several
incorrect mileage points. The 15 and 20-mile arcs were depicted with
incorrect mileage, and the 8-mile arc surrounding the George Bush
Intercontinental Airport did not depict mileage. Except for mileage
corrections made to the graphic, this amendment is the same as that
proposed in the notice.
Regulatory Evaluation Summary
Changes to Federal regulations must undergo several economic
analyses. First, Executive Order 12866 directs that each Federal agency
shall propose or adopt a regulation only upon a reasoned determination
that the benefits of the intended regulation justify its costs. Second,
the Regulatory Flexibility Act of 1980 requires agencies to analyze the
economic effect of regulatory changes on small entities. Third, the
Office of Management and Budget directs agencies to assess the effect
of regulatory changes on international trade. In conducting these
analyses, the FAA has determined that this final rule: (1) Will
generate benefits that justify its costs and is not ``a significant
regulatory action'' as defined in the Executive Order; (2) is not
significant as defined in Department of Transportation's Regulatory
Policies and Procedures; (3) will not have a significant impact on a
substantial number of small entities; (4) will not constitute a barrier
to international trade; and (5) will not contain any Federal
intergovernmental or private sector mandate. Therefore, the
requirements of Title II of the Unfunded Mandates Reform Act of 1995 do
not apply. These analyses are summarized here in the preamble and in
the full Regulatory Evaluation in the docket.
The regulatory evaluation analyzes the potential costs and benefits
of the final rule to amend part 71. This final rule reconfigures
several subareas and establishes a subarea within the Houston, TX,
Class B airspace area. Specifically, this final rule reconfigures
subarea A, expands subarea D, and establishes a subarea E with a floor
of 2,500 feet MSL.
The FAA has determined that this rule will generate benefits for
system users and the agency by enhancing aviation safety and
operational efficiency. Operational efficiency will increase through
the enhanced capability of Houston Air Traffic Control Tower (ATCT) to
provide sequencing and separation of arrivals and departures for IFR
and VFR operations in areas of higher complexity by releasing airspace
in that portion of subarea A where there is less traffic.
The FAA has determined that aircraft operators will not incur any
additional navigational or equipment costs as a result of this rule.
The modification of subarea D slightly expands the overall size of the
Class B airspace area, and will not impose any additional avionics
equipment or circumnavigation cost onto operators. The reconfiguration
of subarea A will move the lateral boundary inward (west), subsequently
reducing the overall size of the subarea. The FAA contends that the
reduction of the subarea lateral boundary may reduce circumnavigation
cost for GA operations.
The final rule will not impose any additional administrative costs
onto the FAA for personnel, facilities, or equipment. This action
provides additional ATC participation in subarea D with higher
operations complexity, but will not expand the Class B airspace area
lateral boundaries beyond the 30 NM arc.
In view of the potential benefits of enhanced aviation safety and
increased operational efficiency and the negligible cost of compliance,
the FAA has determined that this rule will be cost-beneficial.
Regulatory Flexibility Determination
The Regulatory Flexibility Act of 1980 (RFA) was enacted by
Congress to ensure that small entities are not unnecessarily and
disproportionately burdened by Federal regulations. The RFA requires
regulatory agencies to review rules which may have ``a significant
economic impact on a substantial number of small entities.''
The FAA certifies that the final rule will not have an adverse
effect on a substantial number of small entities. This assessment is
based on the premise that potentially impacted operators regularly fly
into airports where radar approach control services have already been
established. In addition, increasing the overall size of the Class B
airspace area by such a small area will not impose any additional cost
on circumnavigating operators for time and fuel. The FAA contends that
the final rule will not result in a significant economic impact on a
substantial number of small entities, in view of the negligible cost of
compliance. Therefore, a regulatory flexibility analysis is not
required under the terms of the RFA.
International Trade Impact Assessment
The final rule will not constitute a barrier to international trade
to either the export of American goods and services to foreign
countries, or to the import of foreign goods and services into the
United States. This modification will not impose costs on aircraft
operators or aircraft manufacturers in the U.S. or foreign countries.
The modifications of the Houston Class B airspace area will only affect
U.S. terminal airspace operating procedures in the vicinity of Houston.
The modification will not have international trade ramifications
because it is a domestic airspace matter that will not impose
additional costs or requirements on affected entities.
Unfunded Mandates Assessment
Title II of the Unfunded Mandates Reform Act of 1995 (Act), enacted
as Pub. L. 104-4 on March 22, 1995, requires each Federal agency, to
the extent permitted by law, to prepare a written assessment of the
effects of any Federal mandate in a proposed or final agency rule that
may result in the expenditure of $100 million or more adjusted annually
for inflation in any one year by State, local, and tribal governments,
in the aggregate, or by the private sector. Section 204(a) of the Act,
2 U.S.C. 1534(a), requires the Federal agency to develop an effective
process to permit timely input by elected officers (or their designees)
of State, local and tribal governments on a proposed ``significant
intergovernmental mandate.'' A ``significant intergovernmental
mandate'' under the Act is any provision in a Federal agency regulation
that would impose an enforceable duty upon State, local and tribal
governments, in the aggregate, of $100 million, adjusted annually for
inflation, in any one year. Section 203 of the Act, 203 U.S.C 1533,
which supplements section 204(a), provides that before establishing any
regulatory requirements that might significantly or uniquely affect
small governments, the agency shall have developed a plan that among
other things, provides for notice to potentially affected small
governments, if any, and for a meaningful and timely opportunity to
provide input in the development of regulatory proposals.
This rule does not contain any Federal intergovernmental or private
sector mandates. Therefore, the requirements of Title II of the
Unfunded Mandates Reform Act of 1995 do not apply.
