[Docket No. 97-CE-33-AD; Amendment 39-10224; AD 97-25-01]
RIN 2120-AA64


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 
(FAA), Central Region, Office of the Regional Counsel, Attention: Rules 
Docket No. 97-CE-33-AD, Room 1558, 601 E. 12th Street, Kansas City, 
Missouri 64106.

    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.

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.
