Airworthiness Directives; Boeing

Model 757 Series Airplanes Equipped

With Rolls Royce Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD),

applicable to certain Boeing Model 757

series airplanes, that currently requires

repetitive inspections to detect fatigue

cracking in the midspar fuse pins;

replacement with new or refinished fuse

pins, if necessary; and repetitive

inspections of newly installed fuse pins.

This AD requires earlier initial

inspections and replacements; more

frequent repetitive inspections of certain

fuse pins; and replacement with new

fuse pins, if necessary. This amendment

is prompted by reports of fatigue

cracking of the midspar fuse pins and by

fatigue test data indicating that current

inspection thresholds and intervals for

repetitive inspections are inadequate to

detect fatigue cracking in a timely

manner. The actions specified in this

AD are intended to detect and correct

such fatigue cracking, which could lead

to separation of the strut and engine

from the wing of the airplane.

DATES: Effective September 17, 1997.

The incorporation by reference of

Boeing Alert Service Bulletin 757–

54A0020, Revision 6, dated July 18,

1997, as listed in the regulations, is

approved by the Director of the Federal

Register as of Sepember 17, 1997.

The incorporation by reference of

Boeing Service Bulletin 757–54A0020,

Revision 5, dated March 17, 1994, as
46190 Federal Register / Vol. 62, No. 169 / Tuesday, September 2, 1997 / Rules and Regulations

listed in the regulations, was approved

previously by the Director of the Federal

Register as of April 10, 1996 (60 FR

9601, March 11, 1996).

SUPPLEMENTARY INFORMATION: On March

1, 1996, the FAA issued AD 96–05–08,

amendment 39–9534 (61 FR 9601,

March 11, 1996), applicable to certain

Boeing Model 757 series airplanes. That

AD requires repetitive inspections to

detect cracking in the midspar fuse pins,

regardless of whether they are straight,

bulkhead, or 15–5PH fuse pins, and

replacement of discrepant pins with

new straight fuse pins, refinished

straight fuse pins, or new corrosionresistant steel (15–5PH) fuse pins,

depending on the type of cracked pin.

The actions required by that AD are

intended to prevent cracking of the

midspar fuse pins, which may lead to

separation of the strut and engine from

the wing of the airplane.

Actions Since Issuance of Previous Rule

Since the issuance of AD 96–05–08,

the FAA has received several reports

indicating the detection of fatigue

cracking on two straight fuse pins and

one broken straight fuse pin on Model

757 series airplanes equipped with Rolls

Royce engines. In these instances,

damage to the fuse pins was detected

before reaching the threshold specified

in AD 96–05–08 for conducting an

initial inspection of the fuse pins. In

addition, since the issuance of that AD,

the FAA was informed by Boeing that

refinished straight fuse pins have a

shorter fatigue life than new straight

fuse pins.

Based on data from fatigue testing by

the manufacturer and the reports of

early cracking, the FAA finds that the

current inspection thresholds and

intervals for repetitive inspections are

inadequate to detect cracking in a timely

manner. Consequently, it is necessary to

lower the threshold for the initial

inspection and conduct repetitive

inspections of these fuse pins more

frequently than currently required by

AD 96–05–08. In addition, the FAA has

determined that the action specified in

paragraph (b)(2)(i) of AD 96–05–08,

which requires the replacement of

cracked refinished straight fuse pins

with crack-free refinished straight fuse

pins, is no longer acceptable. The FAA

concludes that, because of the safety

implications and consequences

associated with the fatigue cracking of

fuse pins, the replacement of refinished

straight fuse pins must be made with

either new straight fuse pins or new 15–

5PH fuse pins. However, the FAA has

determined that the existing refinished

straight fuse pins, which are already

installed on Boeing Model 757 series

airplanes and do not have cracks, may

continue in use in accordance with the

requirements of this AD.

The FAA is considering a separate

rulemaking action to address the same

unsafe condition on certain Model 757

airplanes equipped with Pratt &

Whitney engines.

Explanation of Relevant Service

Information

Since the issuance of AD 96–05–08,

the FAA has reviewed and approved

Boeing Alert Service Bulletin 757–

54A0020, Revision 6, dated July 18,

1997, which continues specifications

similar to those in Boeing Service

Bulletin 757–54A0020, Revision 5,

dated March 17, 1994 (which was

referenced in AD 96–05–08 as the

appropriate source of service

information). The relevant changes in

Revision 6 are procedures for earlier

initial inspections and replacements;

more frequent repetitive inspections of

certain fuse pins; and replacement with

new fuse pins, if necessary. In addition,

Revision 6 specifies the replacement of

cracked refinished straight fuse pins

with new straight fuse pins or 15–5PH

fuse pins.

Explanation of Requirements of Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of this same

type design, this AD supersedes AD 96–

05–08 to continue to require repetitive

inspections to detect cracking in the

midspar fuse pins; replacement with

new or refinished fuse pins, if

necessary; and repetitive inspections of

newly installed fuse pins. This AD

requires earlier initial inspections and

replacements; more frequent repetitive

inspections of certain fuse pins; and

replacement with new fuse pins, if

necessary. This AD also requires the

replacement of cracked refinished

straight fuse pins with new straight fuse

pins or 15–5PH fuse pins. These actions

are required to be accomplished in

accordance with Revision 6 of the alert

service bulletin described previously.

Differences Between the AD and the

Relevant Service Bulletin

Operators should note that, although

Boeing Alert Service Bulletin 757–

54A0020, Revision 6, dated July 18,

1997, specifies that a cracked bulkhead

fuse pin may be replaced with either a

new straight fuse pin or a new 15–5PH

fuse pin, this AD requires a bulkhead

fuse pin to be replaced only with a new

15–5PH fuse pin. The FAA has

determined that because 15–5PH fuse

pins are made from corrosion-resistant

steel, 15–5PH fuse pins are less likely to

be subject to fatigue cracking and stress

corrosion cracking and, as a result, have

a longer service life than straight fuse

pins or bulkhead fuse pins. The FAA

also considers that this action is

necessary to support the continued

airworthiness of Boeing Model 757

series airplanes equipped with Rolls

Royce engines.

Operators also should note that

Revision 6 of the previously described

alert service bulletin specifies the

replacement of bulkhead fuse pins

within 6,000 total flight cycles on the

bulkhead fuse pins. However, this AD

requires the replacement of bulkhead

fuse pins within 3,000 flight cycles on

the bulkhead fuse pins after April 10,

1996, the effective date of AD 96–05–08.

The FAA has determined that

continuing the requirement for such

replacement, which was required in AD

96–05–08, is sufficient to detect and

correct the initiation and propagation of

fatigue cracking in the midspar fuse

pins.

In addition, operators should note

that the applicability of this AD differs

from the effectivity listing in Revision 6

of the previously referenced alert

service bulletin. The FAA has

determined that to adequately address

the problem of fatigue cracking in the

midspar fuse pins, this AD should

include Model 757 series airplanes (all

serial numbers) equipped with Rolls

Royce engines, as previously specified

in AD 96–05–08.
Federal Register / Vol. 62, No. 169 / Tuesday, September 2, 1997 / Rules and Regulations 46191

Interim Action

This is considered to be interim

action until final action is identified, at

which time the FAA may consider

further rulemaking.

Determination of Rule’s Effective Date

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in fewer than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications shall identify the

Rules Docket number and be submitted

in triplicate to the address specified

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this rule must

submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 97–NM–125–AD.’’ The

postcard will be date stamped and

returned to the commenter.

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

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.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and that it is not a ‘‘significant

regulatory action’’ under Executive

Order 12866. It has been determined

further that this action involves an

emergency regulation under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979). If it is

determined that this emergency

regulation otherwise would be

significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

SUPPLEMENTARY INFORMATION:

Background Information

On October 2, 1996, the President

signed into law the Electronic Freedom

of Information Act Amendments of 1996

(‘‘EFOIA’’), Public Law 231, 110 Stat.

3048 (1996). EFOIA includes provisions

authorizing or requiring agencies to

promulgate regulations implementing

certain of its requirements, including

the tracking of Freedom of Information

Act (‘‘FOIA’’) requests, the aggregation

of FOIA requests, and the expedited

processing of FOIA requests. In

addition, EFOIA changes the time limit

for responding to a FOIA request from

ten to twenty days, the requirements for

reporting on FOIA activities to

Congress, and the cases in which an

agency may extend the time for

responding to a FOIA request. EFOIA

also includes provisions regarding the

availability of documents in electronic

form, the treatment of electronic

records, and the establishment of

‘‘electronic reading rooms.’’

On May 6, 1997 the Consumer

Product Safety Commission

(‘‘Commission’’) proposed amendments

to its regulations implementing the

Freedom of Information Act, 16 CFR

Part 1015. See 62 FR 24614, May 6,

1997. The proposed amendments were

intended to revise the Commission’s

FOIA regulations to comply with

EFOIA. The Commission received three

comments in response to the proposed

amendments. The comments are

discussed below. The Commission now

issues the amendments in final form.

They are identical to the proposed

amendments, except for a few changed

words in §§ 1015.2 and 1015.5(f) that

clarify the meaning of those provisions.
