Airworthiness Directives; Boeing

Model 757–200 Series Airplanes

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

certain Boeing Model 757–200 series

airplanes. This proposal would require

modification of certain passenger doors.

This proposal is prompted by reports

that certain passenger doors could not

be opened due to the escape slide shelf

assembly and escape slide falling onto

the girt bar lifting mechanism of the

door. The actions specified by the

proposed AD are intended to prevent

the escape slide shelf assembly and

escape slide from falling on the girt bar

of a passenger door due to failed rivets

of the escape slide shelf assembly, and

consequent inability to open the

passenger door and to use the escape

slide at that door during an emergency

evacuation of the airplane.

DATES: Comments must be received by

December 29, 1997.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

Discussion

The FAA has received reports

indicating that various passenger doors

(Number 1, 2, or 4) could not be opened.

Investigation revealed that the escape

slide shelf assembly and escape slide

had fallen onto the girt bar lifting

mechanism of the passenger door due to

failure of four rivets of the shelf

assembly. Such failure, if not corrected,

could result in inability to open the

Number 1, 2, or 4 passenger door, and

consequent inability to use the escape

slide at the door during an emergency

evacuation of the airplane.

Explanation of Relevant Service

Information

The FAA has reviewed and approved

Boeing Service Bulletin 757–25–0175,

dated May 30, 1996, and Revision 1,

dated March 6, 1997, which describes

procedures for modifying the escape

slide shelf assemblies of the Number 1,

2, and 4 passenger doors. The

modification entails replacing the four

existing rivets of the escape slide shelf

assembly of the passenger doors with

steel rivets. The modification will

ensure that the escape slide shelf

assembly and escape slide do not fall

onto the girt bar lifting mechanism.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other products of this same

type design, the proposed AD would

require modification of the escape slide

shelf assemblies of the Numbers 1, 2,
60808 Federal Register / Vol. 62, No. 219 / Thursday, November 13, 1997 / Proposed Rules

and 4 passenger doors. The actions

would be required to be accomplished

in accordance with the service bulletin

described previously.

Cost Impact

There are approximately 673 Boeing

Model 757–200 series airplanes of the

affected design in the worldwide fleet.

The FAA estimates that 381 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. Required parts

would cost approximately $234 per

airplane. Based on these figures, the cost

impact of the proposed AD on U.S.

operators is estimated to be $226,314, or

$594 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

location provided under the caption

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

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:

Boeing: Docket 96–NM–232–AD.

Applicability: Model 757–200 series

airplanes, as listed in Boeing Service Bulletin

757–25–0175, Revision 1, dated March 6,

1997, certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

otherwise 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 (c) 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 prevent inability to open the Number 1,

2, or 4 passenger door and to use the escape

slide at that door during an emergency

evacuation of the airplane, accomplish the

following:

(a) Within 18 months after the effective

date of this AD, modify the escape slide shelf

assemblies of the Numbers 1, 2, and 4

passenger doors in accordance with Boeing

Service Bulletin 757–25–0175, dated May 30,

1996, or Revision 1, dated March 6, 1997.

(b) As of the effective date of this AD, no

person shall install an escape slide shelf

assembly having part number 416N2400–6 or

416N2400–7 on any airplane.

(c) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Seattle

Aircraft Certification Office (ACO), FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Seattle ACO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Seattle ACO.

(d) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

Issued in Renton, Washington, on

November 6, 1997.

Acting Manager, Transport Airplane

Directorate, Aircraft Certification Service.

Airworthiness Directives; Boeing

Model 737–100, –200, –300, –400, and

–500 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

revise an existing airworthiness

directive (AD), applicable to all Boeing

Model 737–100, –200, –300, –400, and

–500 series airplanes, that currently

requires a one-time inspection to

determine the part number of the engage

solenoid valve of the yaw damper on the

rudder power control unit, and

replacement of the valve with a valve

having a different part number, if

necessary. That AD was prompted by a

review of the design of the flight control

systems on Model 737 series airplanes.

The actions specified by that AD are

intended to prevent sudden

uncommanded yawing of the airplane

due to potential failures within the yaw

damper system, and consequent injury

to passengers and crewmembers. This

action would make certain editorial

changes to clarify the requirements of

the existing AD.
