Federal Register / Vol. 60, No. 105 / Thursday, June 1, 1995 / Rules and Regulations 28529

Applicability: Model MD–11 series

airplanes, equipped with Pratt & Whitney

Model PW4460 and PW4462 engines; as

listed in McDonnell Douglas Alert Service

Bulletin MD11–71A073, Revision 1, dated

May 16, 1995; certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must use the authority

provided in paragraph (d) to request approval

from the FAA. This approval may address

either no action, if the current configuration

eliminates the unsafe condition; or different

actions necessary to address the unsafe

condition described in this AD. Such a

request should include an assessment of the

effect of the changed configuration on the

unsafe condition addressed by this AD. In no

case does the presence of any modification,

alteration, or repair remove any airplane from

the applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent loss of the capability of the aft

mount beam assembly to support engine

loads, and possible separation of the engine

from the airplane, accomplish the following:

detect cracks or discrepancies in the aft

mount beam assembly, part number (P/N)

221–0261–501, of engine numbers 1, 2, and

3, in accordance with McDonnell Douglas

Alert Service Bulletin MD11–71A073,

Revision 1, dated May 16, 1995.

(1) If no cracks or discrepancies are

detected, no further action is required by this

AD.

(2) If any crack or discrepancy is detected,

prior to further flight, replace the cracked or

discrepant aft mount beam assembly with a

new assembly having P/N 221–0261–503, or

an assembly having P/N 221–0261–501 that

has been previously inspected and reidentified, in accordance with paragraph

3.B., Phase 2, of the Accomplishment

Instructions of the alert service bulletin.

Replacement shall be accomplished in

accordance with the procedures specified in

the alert service bulletin.

(b) Within 10 days after accomplishing the

Airworthiness Directives; Jetstream

Aircraft Limited (Formerly British

Aerospace, Regional Aircraft Limited)

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment supersedes

Airworthiness Directive (AD) 90–13–12,

which currently requires modifying the

airplane electrical system and revising

the emergency procedures section of the

Airplane Flight Manual (AFM) on

certain Jetstream Aircraft Limited (JAL)

Jetstream Models 3101 and 3201

airplanes. This action retains the

requirements of AD 90–13–12 for those

airplanes that do not have modified

inverters installed and the inverted

transfer function restored. The Federal

Aviation Administration (FAA) has

determined that installing modified

inverters along with restoring the

inverter transfer function corrects the

problems in the power supply

addressed by AD 90–13–12. The actions

specified by this AD are intended to

prevent alternating current system

failures, which, if not detected and

corrected, could result in damage to the

airplane navigational systems.

DATES: Effective July 19, 1995.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 19,

1995.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an AD that would apply to

certain JAL Models 3101 and 3201

airplanes was published in the Federal

Register on February 10, 1995 (60 FR

7922). The action proposed to supersede

AD 90–13–12 with a new AD that would

(1) retain the requirements of modifying
28530 Federal Register / Vol. 60, No. 105 / Thursday, June 1, 1995 / Rules and Regulations

the airplane electrical system and

revising the emergency procedures

section of the AFM required by AD 90–

13–12; and (2) require these

modification and revisions only for

those airplanes that do not have

modified inverters, P/N 1B350–1B1–3,

installed in accordance with the

instructions in Jetstream Service

Bulletin (SB) 24–JM 7740, dated

November 15, 1990, and do not have the

inverter transfer function restored in

accordance with the instructions in

Jetstream SB 24–JA 900941, dated

November 14, 1990; or Jetstream SB 24–

JA 900941, Revision 1, dated February

18, 1992. Accomplishment of the

proposed airplane electrical

modifications would be in accordance

with Jetstream Alert Service Bulletin

(ASB) 24–A–JA 900443, Revision 1,

dated May 1, 1990; and Jetstream ASB

24–A–JM 7708, Revision 1, dated May

22, 1990.

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 careful review of all available

information related to the subject

presented above, the FAA has

determined that air safety and the

public interest require the adoption of

the rule as proposed except for minor

editorial corrections. The FAA has

determined that these minor corrections

will not change the meaning of the AD

and will not add any additional burden

upon the public than was already

proposed.

The FAA estimates that 180 airplanes

in the U.S. registry will be affected by

this AD, that it will take approximately

10 workhours per airplane to

accomplish the required action, and that

the average labor rate is approximately

$60 an hour. Based on these figures, the

total cost impact of this AD on U.S.

operators is estimated to be $108,000.

This figure is based on the assumption

that no affected owner/operator has

accomplished the required

modification.

Since AD 90–13–12, which this AD

supersedes, requires the same actions

(except for a limit in the airplane

applicability), there is no additional cost

of this AD on U.S. operators. The

$28,800 cost difference between this AD

(estimated $108,000) and superseded

AD 90–04–04 (estimated $79,200) is a

result of inflationary costs used in

determining the costs of labor ($60 per

hour as opposed to $40 per hour).

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

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.

[Docket No. 28226; Amdt. No. 1665]

Standard Instrument Approach

Procedures; Miscellaneous

Amendments

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This amendment establishes,

amends, suspends, or revokes Standard

Instrument Approach Procedures

(SIAPs) for operations at certain

airports. These regulatory actions are

needed because of the adoption of new

or revised criteria, or because of changes

occurring in the National Airspace

System, such as the commissioning of

new navigational facilities, addition of

new obstacles, or changes in air traffic

requirements. These changes are

designed to provide safe and efficient

use of the navigable airspace and to

promote safe flight operations under

instrument flight rules at the affected

airports.

DATES: An effective date for each SIAP

is specified in the amendatory

provisions.

ADDRESSES: Availability of matters

incorporated by reference in the

amendment is as follows:

For Examination—

1. FAA Rules Docket, FAA

Headquarters Building, 800

Independence Avenue, SW.,

Washington, DC 20591;

2. The FAA Regional Office of the

region in which the affected airport is

located; or

3. The Flight Inspection Area Office

which originated the SIAP.

For Purchase—Individual SIAP

copies may be obtained from:

1. FAA Public Inquiry Center (APA–

200), FAA Headquarters Building, 800

SUPPLEMENTARY INFORMATION: This

amendment to part 97 of the Federal

Aviation Regulations (14 CFR part 97)

establishes, amends, suspends, or

revokes Standard Instrument Approach

Procedures (SIAPs). The complete

regulatory description of each SIAP is

contained in official FAA form

documents which are incorporated by

reference in this amendment under 5

U.S.C. 552(a), 1 CFR part 51, and § 97.20

of the Federal Aviation Regulations

(FAR). The applicable FAA Forms are

identified as FAA Forms 8260–3, 8260–

4, and 8260–5. Materials incorporated

by reference are available for

examination or purchase as stated

above.

The large number of SIAPs, their

complex nature, and the need for a

special format make their verbatim

publication in the Federal Register

expensive and impractical. Further,

airmen do not use the regulatory text of

the SIAPs, but refer to their graphic

depiction on charts printed by

publishers of aeronautical materials.

Thus, the advantages of incorporation

by reference are realized and

publication of the complete description

of each SIAP contained in FAA form

documents is unnecessary. The

provisions of this amendment state the

affected CFR (and FAR) sections, with

the types and effective dates of the

SIAPs. This amendment also identifies

the airport, its location, the procedure

identification and the amendment

number.

The Rule

This amendment to part 97 is effective

upon publication of each separate SIAP

as contained in the transmittal. Some

SIAP amendments may have been

previously issued by the FAA in a

National Flight Data Center (FDC)

Notice to Airmen (NOTAM) as an

emergency action of immediate flight

safety relating directly to published

aeronautical charts. The circumstances

which created the need for some SIAP

amendments may require making them

effective in less than 30 days. For the

remaining SIAPs, an effective date at

least 30 days after publication is

provided.

Further, the SIAPs contained in this

amendment are based on the criteria

contained in the U.S. Standard for

Terminal Instrument Approach

Procedures (TERPS). In developing

these SIAPs, the TERPS criteria were

applied to the conditions existing or

anticipated at the affected airports.

Because of the close and immediate

relationship between these SIAPs and

safety in air commerce, I find that notice

and public procedure before adopting

these SIAPs are impracticable and

contrary to the public interest and,

where applicable, that good cause exists

for making some SIAPs effective in less

than 30 days.

The FAA has determined that this

regulation only involves an established

body of technical regulations for which

frequent and routine amendments are

necessary to keep them operationally

current. It, therefore—(1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a
