14 CFR Part 39
[Docket No. 95-NM-255-AD; Amendment 39-9719; AD 96-17-10]
RIN 2120-AA64
Airworthiness Directives; Beech Model 400, 400A, MU-300-10, and
2000 Airplanes, and Model 200, B200, 300, and B300 Series Airplanes
Agency: Federal Aviation Administration, DOT.
Action: Final rule.
-----------------------------------------------------------------------
Summary: This amendment adopts a new airworthiness directive (AD),
applicable to certain Beech Model 400, 400A, MU-300-10, and 2000
airplanes, and Model 200, B200, 300, and B300 series airplanes, that
requires replacement of outflow/safety valves with serviceable valves.
This amendment is prompted by a report of cracking and subsequent
failure of outflow safety valves in the pressurization system. The
actions specified by this AD are intended to prevent such cracking and
subsequent failure of the outflow/safety valves, which could result in
rapid decompression of the airplane.
Dates: Effective September 24, 1996.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 24, 1996.
Addresses: The service information referenced in this AD may be
obtained from AlliedSignal Aerospace, Technical Publications, Dept. 65-
70, P.O. Box 52170, Phoenix, Arizona 85072-2170. This information may
be examined at the Federal Aviation Administration (FAA), Transport
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton,
Washington; or at the FAA, Los Angeles Aircraft Certification Office,
Transport Airplane Directorate, 3960 Paramount Boulevard, Lakewood,
California; or at the Office of the Federal Register, 800 North Capitol
Street, NW., suite 700, Washington, DC.

Supplementary Information: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Beech Model 400, 400A, MU-
300-10, and 2000 airplanes, and Model 200, B200, 300, and B300 series
airplanes was published in the Federal Register on April 15, 1996 (61
FR 16416). That action proposed to require replacement of certain
discrepant outflow/safety valves with serviceable valves.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
The FAA has determined that air safety and the public interest require
the adoption of the rule as proposed.
Cost Impact
There are approximately 150 Beech Model 400, 400A, MU-300-10, and
2000 airplanes, and Model 200, B200, 300, and B300 series airplanes of
the affected design in the worldwide fleet. The FAA estimates that 105
airplanes of U.S. registry will be affected by this AD, that it will
take approximately 12 work hours per airplane to accomplish the
required actions, and that the average labor rate is $60 per work hour.
The parts manufacturer has advised that it will provide replacement
parts at no cost to operators. Based on these figures, the cost impact
of the AD on U.S. operators is estimated to be $75,600, or $720 per
airplane.
[[Page 42997]]
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the 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 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.
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) 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 final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
Addresses.

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends 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.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
96-17-10 Beech Aircraft Corporation: Amendment 39-9719. Docket 95-
NM-255-AD.
Applicability: Model 400, 400A, MU-300-10, and 2000 airplanes,
Model 200 and B200 series airplanes having a maximum altitude
capability of greater than 31,000 feet, and Model 300 and B300
series airplanes; equipped with AlliedSignal outflow/safety valves,
as identified in AlliedSignal Aerospace Service Bulletins 103570-21-
4012 and 103648-21-4022, both Revision 1, both dated May 30, 1995;
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 (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 cracking and subsequent failure of the outflow/safety
valves, which could result in rapid decompression of the airplane,
accomplish the following:
(a) Within 18 months after the effective date of this AD,
replace the outflow/safety valve in accordance with AlliedSignal
Aerospace Service Bulletin 103570-21-4012 (for airplanes equipped
with valves having part number 103570-25, 103570-26, or 103570-27),
or 103648-21-4022 (for airplanes equipped with valves having part
number 103648-1, 103648-3, 103648-4, 103648-5, 103648-6, 103648-7,
or 103648-13), both Revision 1, both dated May 30, 1995, as
applicable.
(b) As of the effective date of this AD, no person shall install
an outflow/safety valve, having a part number and serial number
identified in AlliedSignal Aerospace Service Bulletin 103570-21-4012
(for airplanes equipped with valves having part number 103570-25,
103570-26, or 103570-27), or 103648-21-4022 (for airplanes equipped
with valves having part number 103648-1, 103648-3, 103648-4, 103648-
5, 103648-6, 103648-7, or 103648-13), both Revision 1, both dated
May 30, 1995, on any airplane unless that valve is considered to be
serviceable in accordance with the applicable service bulletin.
(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, Los Angeles 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, Los Angeles ACO.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Los Angeles 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.
(e) The replacement shall be done in accordance with
AlliedSignal Aerospace Service Bulletin 103570-21-4012, or 103648-
21-4022, both Revision 1, both dated May 30, 1995. This
incorporation by reference was approved by the Director of the
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part
51. Copies may be obtained from AlliedSignal Aerospace, Technical
