Airworthiness Directives; Raytheon Aircraft Company 58, 60, 90,
100, 200, and 300 Series and Model 2000 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to all Raytheon Aircraft Company (Raytheon) 58, 60, 90, 100,
200, and 300 series and Model 2000 airplanes (formerly referred to as
Beech 58, 60, 90, 100, 200, and 300 series and Beech Model 2000
airplanes). This AD requires replacing certain AlliedSignal Aerospace
outflow/safety valves in the pressurization system with new or
serviceable valves. The 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 AlliedSignal outflow/safety valves.
The actions specified by this AD are intended to prevent outflow/safety
valve cracking and consequent failure, which could result in rapid
decompression of the airplane.
EFFECTIVE DATE: January 11, 1998.
ADDRESSES: Service information that applies to the proposed AD may be
obtained from AlliedSignal Aerospace, Technical Publications,
Department 65-70, P.O. Box 52170, Phoenix, Arizona 85072-2170. This
information also may be examined at the Federal Aviation Administration

----------------------------------------------------------------------------------------------------------------
The NPRM resulted 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 AlliedSignal outflow/safety valves.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the one comment received on the proposal. No comments have been
received regarding the FAA's estimate of the cost impact upon the
public.
Comment Disposition
Raytheon states that the FAA made the following typographical
errors in the Applicability section of the NPRM:
--Model B300 airplane serial numbers were referenced as F1-1
through F1-72 instead of FL-1 through FL-72; and
--Model 200T airplane serial numbers were referenced as B-1 through
BT-32 instead of BT-1 through BT-32.
Raytheon requests that the FAA include the correct serial number
designations for these airplanes in the final rule.
The FAA concurs with the commenter. The FAA inadvertently
referenced the wrong serial numbers for the Models 200T and B300
airplanes. The final rule will reflect the correct serial number
designations for these airplanes.
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 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 revising AD 96-17-10 in another action to retain
the requirements for the airplanes certificated under 14 CFR part 25.
Compliance Time of This 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). The 4-month compliance time of this AD will coincide with the
compliance time included in AD 96-17-10. Both actions will be required
around March 1998.
[[Page 63833]]
Cost Impact
The FAA estimates that 2,386 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 12 workhours per
airplane to accomplish the required action, and that the average labor
rate is approximately $60 an hour. AlliedSignal will provide parts at
no cost to the owner/operator. Based on these figures, the total cost
impact of this AD on US 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 required action.
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 copy of the final 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

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 AlliedSignal 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 documents at the
FAA, Central Region, Office of the Regional Counsel, Room 1558, 601
E. 12th Street, Kansas City, Missouri 64106.
(f) This amendment (39-10224) becomes effective on January 11,
1998.
Issued in Kansas City, Missouri, on November 25, 1997.
