Airworthiness Directives; Boeing

Model 737–100 and –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 737–100 and –200

series airplanes. This proposal would

require replacement of the 250 voltampere (VA) rated static inverters with

410 or 500 VA rated static inverters, and

an operational test of the standby

electrical power system. This proposal

is prompted by a report that

accomplishment of a certain

modification could result in overload of

the static inverter on these airplanes.

The actions specified by the proposed

AD are intended to prevent overload of

the static inverter, which could result in

the loss of the 115 volt alternating

current standby bus and the associated

flight instruments when the airplane is

operating on standby electrical power.

Discussion

The FAA has received a report

indicating that, during an engineering

review of Revision 4 to Boeing Service

Bulletin 737–24–1051 by the

manufacturer, it was found that the

effectivity listing of the original issue

through Revision 4 of this service

bulletin included some Boeing Model

737–100 and -200 series airplanes

equipped with 250 volt-ampere (VA)-

rated static inverters. That particular

static inverter may overload on these

airplanes if the modification described

in these particular revisions of the

service bulletin has been accomplished.

The modification entails revising the

power connections to the captain’s

instrument panel. Such an overload on

the static inverters could result in the

loss of the 115 VAC standby bus and the

associated flight instruments when the

airplane is operating on standby electric

power. Loss of use of these components

may adversely affect the handling

characteristics of the airplane.

FAA’s Conclusions

Based on the information obtained

from the manufacturer’s review, the

FAA finds that static inverters rated at

410 VA or 500 VA can safely handle the

increase in electrical loading of the 115

VAC standby bus when the modification

specified in Service Bulletin 737–24–

1051 (the original issue through

Revision 4) is accomplished. Therefore,

the FAA has determined that

replacement of 250 VA-rated static

inverters with 410 VA or 500 VA-rated

static inverters will positively address

the identified unsafe condition.

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 replacement of the 250 VA-rated

static inverters with certain 410 or 500

VA-rated static inverters. This

replacement would be required only on

those airplanes on which the

modification specified in the various

revisions of Boeing Service Bulletin

737–24–1051 has been accomplished.

After accomplishment of the

replacement, the proposed AD would

also require performing an operational

test of the standby electrical power

system.
Federal Register / Vol. 61, No. 111 / Friday, June 7, 1996 / Proposed Rules 29039

The proposed actions would be

required to be accomplished in

accordance with the Boeing 737

Airplane Maintenance Manual.

Cost Impact

There are approximately 51 Boeing

Model 737–100 and -200 series

airplanes of the affected design in the

worldwide fleet. The FAA estimates that

1 airplane of U.S. registry would be

affected by this proposed AD, that it

would take approximately 2 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 $10,500 per

airplane. Based on these figures, the cost

impact of the proposed AD on U.S.

operators is estimated to be $10,620.

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–06–AD.

Applicability: Model 737–100 and –200

series airplanes; equipped with 250 voltampere (VA) rated static inverters; on which

the modification specified in Boeing Service

Bulletin 737–24–1051 (original issue, dated

October 20, 1988; Revision 1, dated October

5, 1989; Revision 2, dated June 28, 1990;

Revision 3, dated May 7, 1992; or Revision

4, dated December 21, 1995) has been

accomplished; 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 (b) 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 overload of the static inverter,

which could result in the loss of the 115 VAC

standby power and the associated flight

instruments, accomplish the following:

(a) Within 10 months after the effective

date of this AD, replace the 250 VA rated

static inverters either with 500 VA-rated

static inverters having Boeing part number

(P/N) 60B40023–2, or with 410 VA-rated

static inverters having Jet Electronics and

Technology P/N 3S2060DV109B1, in

accordance with Section 20–10–111 of the

Boeing 737 Airplane Maintenance Manual.

Prior to further flight following the

replacement, perform an operational test of

the standby electrical power system in

accordance with Section 24–54–0 of the

Boeing 737 Airplane Maintenance Manual.

Note 2: Replacements and operational tests

accomplished prior to the effective date of

this amendment in accordance with Boeing

Alert Service Bulletin 737–24A2113, dated

February 29, 1996, are considered acceptable

for compliance with this AD.

(b) 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 3: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Seattle ACO.

(c) 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 June 3,

1996.
