AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to all

British Aerospace Model BAC 1–11 200

and 400 series airplanes. This proposal

would require repetitive ultrasonic

inspections to detect cracking of the

lugs of the engine mounting beams, and

replacement of the beam with a

serviceable part, if necessary. This

proposal is prompted by reports of

fatigue cracking of the lugs of the engine

mounting beams. The actions specified

by the proposed AD are intended to

detect and correct such cracking of the

engine mounting lugs, which could

result in reduced structural capability of

the engine mount.

Discussion

The Civil Aviation Authority (CAA),

which is the airworthiness authority for
Federal Register / Vol. 62, No. 31 / Friday, February 14, 1997 / Proposed Rules 6893

the United Kingdom, recently notified

the FAA that an unsafe condition may

exist on all British Aerospace Model

BAC 1–11 200 and 400 series airplanes.

The CAA advises that it has received

two reports of fatigue cracking of the

upper rear engine mounting beam. In

one instance, the airplane had

accumulated 11,344 flight hours and

logged 6,267 landings. In the other

instance, the airplane had accumulated

1,740 flight hours and logged 858

landings. In the latter instance, the crack

of the lug had opened sufficiently to be

detected visually and had propagated in

the longitudinal direction of the beam

from the bore to the outside edge of the

lug. Such cracking of the lugs of the

engine mounting beam, if not detected

and corrected, could result in reduced

structural capability of the engine

mount.

Explanation of Relevant Service

Information

British Aerospace has issued Alert

Service Bulletin 53–A–PM6032, Issue 1,

dated April 7, 1995, which describes

procedures for repetitive ultrasonic

inspections to detect cracking of the

lugs of the lower forward, lower rear,

upper forward, and upper rear engine

mounting beams, and replacement of

the beam with a serviceable part, if

necessary. The CAA classified this

service bulletin as mandatory in order to

assure the continued airworthiness of

these airplanes in the United Kingdom.

FAA’s Conclusions

This airplane model is manufactured

in the United Kingdom and is type

certificated for operation in the United

States under the provisions of § 21.29 of

the Federal Aviation Regulations (14

CFR 21.29) and the applicable bilateral

airworthiness agreement. Pursuant to

this bilateral airworthiness agreement,

the CAA has kept the FAA informed of

the situation described above. The FAA

has examined the findings of the CAA,

reviewed all available information, and

determined that AD action is necessary

for products of this type design that are

certificated for operation in the United

States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

repetitive ultrasonic inspections to

detect cracking of the lugs of the lower

forward, lower rear, upper forward, and

upper rear engine mounting beams, and

replacement of the beam with a

serviceable part, if necessary. The

actions would be required to be

accomplished in accordance with the

alert service bulletin described

previously.

Operators should note that certain

compliance times in the proposed AD

are specified in landings or flight hours,

as well as calendar time. The FAA has

determined that, since fatigue cracking

is directly related to the number of

landings, the compliance times should

be specified in landings that are based

on the earliest number of landings

known to have been completed when

cracking of the lugs of the engine

mounting beams were detected.

Cost Impact

The FAA estimates that 31 British

Aerospace Model BAC 1–11 200 and

400 series airplanes of U.S. registry

would be affected by this proposed AD,

that it would take approximately 6 work

hours per airplane to accomplish the

proposed actions, and that the average

labor rate is $60 per work hour. Based

on these figures, the cost impact of the

proposed AD on U.S. operators is

estimated to be $11,160 or $360 per

airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this AD were not adopted.

Regulatory Impact

The regulations proposed herein

would 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

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

For the reasons discussed above, I

certify that this proposed regulation (1)

is not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not

a ‘‘significant rule‘‘ under the DOT

Regulatory Policies and Procedures (44

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

promulgated, 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 draft

regulatory 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

Administration proposes to amend part

39 of the Federal Aviation Regulations

(14 CFR part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

British Aerospace Airbus Limited (Formerly

British Aerospace Commercial Aircraft

Limited, British Aerospace Aircraft

Group): Docket 96–NM–188–AD.

Applicability: All Model BAC 1–11 200

and 400 series airplanes, 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 request approval for an

alternative method of compliance in

accordance with paragraph (d) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To detect and correct cracking of the

engine mounting lugs, which could result in

reduced structural capability of the engine

mount; accomplish the following:

(a) Perform an ultrasonic inspection to

detect cracking of the lugs of the lower

forward, lower rear, upper forward, and

upper rear of the engine mounting beams in

accordance with British Aerospace Alert

The Proposal

The FAA is considering an

amendment to part 71 of the Federal

Aviation Regulations (14 CFR part 71) to

amend Class E airspace at Burlington,

Colorado, to accommodate new SIAPS

at Kit Carson County Airport. The area

would be depicted on aeronautical

charts for pilot reference. The

coordinates for this airspace docket are

based on North American Datum 83.

Class E airspace areas extending upward

from 700 feet or more above the surface

of the earth are published in Paragraph

6005 of FAA Order 7400.9D dated

September 4, 1996, and effective

September 16, 1996, which is

incorporated by reference in 14 CFR

71.1. The Class E airspace designation

listed in this document would be

published subsequently in the Order.

The FFA has determined that this

proposed 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 ‘‘significant

rule’’ under DOT Regulatory Policies

and Procedures (44 FR 11034; February

26, 1979); and (3) does not warrant

preparation of a regulatory evaluation as

the anticipated impact is so minimal.

Since this is a routine matter that will

only affect air traffic procedures and air

navigation, it is certified that this rule,

while promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.
