AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies to Burkhardt Grob Luft-und

Raumfahrt, GmbH. (Grob) Model G 103

Twin Astir sailplanes. This action

requires replacing the airbrake overcenter lever and installing new

inspection holes. The AD is the result of

cracked airbrake over-center levers

found during routine inspections. The

actions specified by this AD are

intended to prevent an asymmetrical

airbrake deployment, which could

result in an uncontrollable roll and

possible loss of control of the sailplane.

DATES: Effective December 29, 1997.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of December

29, 1997.

ADDRESSES: Service information that

applies to this AD may be obtained from

Grob Luft-und Raumfahrt, GmbH., D–

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This

AD

A proposal to amend part 39 of the

Federal Aviation Regulations (14 CFR

part 39) to include an AD that would

apply to Grob Model G 103 Twin Astir

sailplanes was published in the Federal

Register on December 23, 1996 (61 FR

67506). The action proposed to require

replacing the airbrake over-center lever

(Grob part number (P/N) 103–4123 (left)

and P/N 103–4124 (right)) with a new

part of improved design, (Grob P/N

103B–4123 (left) and 103B–4124 (right),

or FAA-approved equivalent part

numbers) and installing new inspection

holes.

Accomplishment of the proposed

action would be in accordance with

Grob Service Bulletin TM 315–47/2,

dated January 20, 1993, and Grob Repair

Instructions No. 315–45/2, dated

October 11, 1991.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were received on the

proposed rule or the FAA’s

determination of the cost to the public.

After examining all information

related to this AD, the FAA has noticed

two discrepancies in the NPRM that

should be clarified in the final rule.

First, clarification is required

regarding Grob Repair Instructions TM

315–45/2. There is a difference between

the dimensions called out in Drawing 3

of Grob Repair Instructions TM 315–45/

2 and the dimensions called out in the

materials list on page one of the Repair

Instructions for the composite sheet

used for the 2 composite stops.

Specifically, refer to the material list on

page one of the repair instructions,

which calls out 2 stops of 3mm × 30mm

× 30mm composite sheet. Drawing 3

calls out the composite sheet material as

3mm × 30mm × 40mm, but should

actually call out the composite sheet

material as 3 × 30 × 30. The material list

on page one is the correct dimension.

Second, there are only 18 Grob Model

G 103 sailplanes in the U.S. registry

rather than the figure of 60 sailplanes

that was originally published in the

NPRM. This would lower the cost

impact on the U.S. operators, and would

not have an adverse impact.

The FAA’s Determination

After careful review of all available

information related to the subject

presented above, including the service

information, the FAA has determined

that air safety and the public interest

require the adoption of the rule as

proposed except for the addition of a

note to refer to the materials list for

correct dimensions on the composite

sheet, the lowering of the number of

sailplanes affected, and minor editorial

corrections. The FAA has determined

that these corrections will not change

the meaning of the AD and will not add

any additional burden upon the public

than was already proposed.

Cost Impact

The FAA estimates that 18 sailplanes

in the U.S. registry will be affected by

this AD, that it will take approximately

12 workhours per sailplane to

accomplish the action, and that the

average labor rate is approximately $60

an hour. Parts cost approximately $650

per sailplane. Based on these figures,

the total cost impact of the AD on U.S.

operators is estimated to be $24,660 or

$1,370 per sailplane.

Regulatory Impact

The regulations adopted herein will

not have substantial direct effects on the

States, on the relationship between the

National Government and the States, or

on the distribution of power and
Federal Register / Vol. 62, No. 228 / Wednesday, November 26, 1997 / Rules and Regulations 62949

responsibilities among the various

levels of government. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979); and (3)

will not have a significant economic

impact, positive or negative, on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act. A copy of the final

evaluation prepared for this action is

contained in the Rules Docket. A copy

of it may be obtained by contacting the

Rules Docket at the location provided

under the caption ADDRESSES.

Clean Air Act Approval and

Promulgation of Title V Operating

Permits Program Revisions; State

Implementation Plan Revision, Santa

Barbara County Air Pollution Control

District, California

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Final rule.

SUMMARY: EPA is finalizing the approval

of a revision to Rule 1301 of Regulation

XIII proposed in the Federal Register on

September 3, 1997, both as a revision to

the federally-approved State

Implementation Plan (SIP) and as a

revision to the title V operating permit

program adopted by the Santa Barbara

County Air Pollution Control District

(Santa Barbara, SBCAPCD, or District)

on September 18, 1997. This approval

action will incorporate this rule into the

federally approved SIP. The intended

effect of approving this revision is to

allow Department of Defense (DoD)

facilities to become exempt from title V

of the Clean Air Act permit

requirements, if the source implements

an emission reduction plan that

achieves a minimum reduction of 10

tons per year of ozone precursors.

Thus, EPA is finalizing the approval

of this rule as a revision to the title V

operating permit program, and as a

revision into the California SIP under

provisions of the CAA regarding EPA

action on SIP submittals, SIPs for

national primary and secondary ambient

air quality standards and plan

requirements for nonattainment areas.

EFFECTIVE DATE: This action is effective

on December 26, 1997.

ADDRESSES: Copies of the rule revision

and EPA’s evaluation report is available

for public inspection at EPA’s Region IX

office during normal business hours.

Copies of the submitted rule revision is
