ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

adopt a new airworthiness directive

(AD) that would apply to certain

Raytheon Aircraft Company (Raytheon)

58, 60, 90, 100, 200, and 300 series and

Model 2000 airplanes. The proposed

action would require replacing certain

AlliedSignal Aerospace outflow/safety

valves in the pressurization system with

new or serviceable valves. The proposed

AD results from a report of cracking and

consequent failure of the affected

outflow safety valves in the

pressurization system. Investigation has

revealed problems during the

manufacturing process of certain Allied

Signal outflow/safety valves. The

actions specified by the proposed AD

are intended to prevent outflow/safety

valve cracking and consequent failure,

which could result in rapid

decompression of the airplane.

Discussion

The FAA has received a report of an

outflow/safety valve in the

pressurization system failing on a

Learjet Model 31A airplane, which

resulted in depressurization of the

airplane. Investigation of this outflow/

safety valve (manufactured by

AlliedSignal) revealed that the poppets

of the valve were cracked.

These outflow/safety valves have been

manufactured since January 1, 1989.

Additional testing has shown that some

of these outflow/safety valves

manufactured since January 1, 1989, are

susceptible to cracking because of

improper injection molding during the

manufacturing process.

The condition is traced to one of two

lots (batch-runs) of molded poppets

installed in valves since 1989. Research

of these lots has revealed brittleness of

these parts, which is characteristic of

improper processing during injection

molding. Tensile stress then develops

upon installation of the poppet, which

leads to hairline cracks. Small cracks

have no effect, but can develop into

larger cracks that cause an increase in

the valve operating pressure, which

could result in cabin depressurization.

The outflow/safety valves installed in

Raytheon 58, 60, 90, 100, 200, and 300

series and Model 2000 airplanes are

similar to the valves installed on the

Learjet Model 31A airplane involved in

the above-referenced incident. The

outflow/safety valves installed at the

factory on the affected airplanes were

manufactured after September 1, 1991,

and before October 1, 1996.

The FAA’s Determination

After examining the circumstances

and reviewing all available information

related to the incidents described above,

including the referenced service

information, the FAA has determined

that AD action should be taken to

prevent outflow/safety valve cracking

and consequent failure, which could

result in rapid decompression of the

airplane.
Federal Register / Vol. 62, No. 149 / Monday, August 4, 1997 / Proposed Rules 41903

Explanation of the Provisions of the

Proposed AD

Since an unsafe condition has been

identified that is likely to exist or

develop in other Raytheon 58, 60, 90,

100, 200, and 300 series and Model

2000 airplanes of the same type design

that have an AlliedSignal Aerospace

outflow/safety valve (referenced above

in the discussion of the service

information) installed, the proposed AD

would require replacing outflow/safety

valves with new or serviceable valves.

Accomplishment of the proposed

replacement would be in accordance

with the applicable maintenance or

service manual.

Similar Actions Required on the

Affected Airplanes

On August 12, 1996, the FAA issued

AD 96–17–10, Amendment 39–9719 (61

FR 42996, August 20, 1996), which

requires replacing the outflow/safety

valves with serviceable valves on

certain Raytheon Model 400, 400A,

MU–300–10, and 2000 airplanes, and

200, B200, 300, and B300 series

airplanes. The FAA inadvertently

included the Raytheon 200, B200, 300,

and B300 series and Model 2000

airplanes in the applicability of AD 96–

17–10. These airplanes are certificated

under part 23 of the Federal Aviation

Regulations (14 CFR part 23), and the

FAA has determined that these

airplanes should be addressed in this

proposed AD along with certain other

Raytheon airplanes certificated under 14

CFR part 23. The Raytheon Models 400,

400A, and MU–300–10 airplanes are

certificated under part 25 of the Federal

Aviation Regulations (14 CFR part 25).

The FAA is proposing a revision to AD

96–17–10 in another action to retain the

requirements for the airplanes

certificated under 14 CFR part 25.

Compliance Time of the Proposed AD

The FAA has determined that an

interval of 4 months is an appropriate

compliance time to address the

identified unsafe condition in a timely

manner. This compliance time was

deemed appropriate after considering

the safety implications, the average

utilization rate of the affected fleet, and

the availability of the replacement parts.

In addition, this compliance time will

coincide with the compliance time

originally included in AD 96–17–10 of

18 months after the effective date

(effective date: September 24, 1996 plus

18 months = March 24, 1998). Should

the proposed rule become a final rule,

this would occur around November

1997. Based on this information, the 4-

month compliance time of the proposed

AD will coincide with the compliance

time included in AD 96–10–17. Both

should become effective in March 1998.

Cost Impact

The FAA estimates that 2,386

airplanes in the U.S. registry would be

affected by the proposed AD, that it

would take approximately 12 workhours

per airplane to accomplish the proposed

action, and that the average labor rate is

approximately $60 an hour. Allied

Signal will provide parts at no cost to

the owner/operator. Based on these

figures, the total cost impact of the

proposed AD on U.S. operators is

estimated to be $1,717,920 or $720 per

airplane. The FAA knows of no affected

airplane owner/operator that has

already accomplished the proposed

action.

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 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) 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 has been placed in the Rules

Docket. A copy of it may be obtained by

contacting the Rules Docket at the

1, dated May 30, 1995. In addition,

Beechcraft Service Bulletin 2484, Revision 1,

dated October, 1995, references the

AlliedSignal service bulletins.

Note 2: 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 in the

body of this AD, unless already

accomplished.

To prevent outflow/safety valve cracking

and consequent failure, which could result in

rapid decompression of the airplane,

accomplish the following:

(a) For the airplanes referenced in the

‘‘Airplane Models and Serial Numbers That

Are Equipped with Allied Signal Outflow

Valves’’ table that is included in the

‘‘Applicability’’ section of this AD: Within

the next 4 months after the effective date of

this AD, replace (with a new or serviceable

valve) any outflow/safety valve that does not

have one of the following:

(1) The valve identification plate MOD

RECORD stamped ‘‘PCA’’ (Poppet Change

Accomplished); or

(2) A valve with an inked ATD Quality

Assurance ‘‘Functional Test (FT)’’ stamp that

is dated June 1992, or later.

(b) For all airplanes: As of the effective

date of this AD, no person may install on any

affected airplane any outflow/safety valve

that is referenced in the ‘‘Applicable Outflow

Safety Valves With Applicable Airplane

Models’’ table that is included in the

‘‘Applicability’’ section of this AD.

(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.

(d) An alternative method of compliance or

adjustment of the compliance time that

provides an equivalent level of safety may be

approved by the Manager, Wichita Aircraft

Certification Office (ACO), 1801 Airport

Road, Room 100, Mid-Continent Airport,

Wichita, Kansas 67209. The request shall be

forwarded through an appropriate FAA

Maintenance Inspector, who may add

comments and then send it to the Manager,

Wichita ACO.

Note 3: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Wichita ACO.

(e) All persons affected by this directive

may obtain copies of the documents referred

to herein upon request to AlliedSignal

Aerospace, Technical Publications,

Department 65–70, P.O. Box 52170, Phoenix,

Arizona 85072–2170; or may examine these

Approval and Promulgation of Air

Quality Implementation Plans;

Maryland; Control of Volatile Organic

Compound Emissions From

Degreasing Operations and Vehicle

Refinishing, and Definition of Motor

Vehicle

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve

the State Implementation Plan (SIP)

revisions submitted by the State of

Maryland for the purpose of establishing

volatile organic compound (VOC)

emission control requirements for

degreasing operations and vehicle

refinishing. EPA is also proposing to

approve the SIP revision submitted by

the State of Maryland that establishes a

definition for the term ‘‘motor vehicle.’’

In the final rules section of this Federal

Register, EPA is approving the State’s

SIP revisions as a direct final rule

without prior proposal because the

Agency views them as noncontroversial

SIP revisions and anticipates no adverse

comments. A detailed rationale for the

approval is set forth in the direct final

rule. If no adverse comments are

received in response to this proposed

rule, no further activity is contemplated

in relation to this rule. If EPA receives

adverse comments, the direct final rule

will be withdrawn and all public

comments received will be addressed in

a subsequent final rule based on this

proposed rule. EPA will not institute a

second comment period on this action.

Any parties interested in commenting

on this action should do so at this time.

DATES: Comments must be received in

writing by September 3, 1997.

ADDRESSES: Written comments on this

action should be addressed to David L.
