Airworthiness Directives; Raytheon Aircraft Company Model 1900D 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Raytheon Aircraft Company (Raytheon) Model 1900D 
airplanes. This action requires modifying the airplane by incorporating 
Raytheon Kit No. 129-5200-1, ``Ground Fine Switch Installation Kit''. 
This action is the result of design analysis during certification of 
5.5 degree approach landings of the Model 1900D airplanes. The actions 
specified by this AD are intended to prevent a loose or misrigged 
ground fine switch, which could result in very hard landings causing 
structural damage to the airplane and possible passenger injury.

DATES: Effective August 3, 1998.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of August 3, 1998.

ADDRESSES: Service information that applies to this AD may be obtained 
from Raytheon Aircraft Company, P. O. Box 85, Wichita, Kansas 67201-
0085; telephone: (800) 625-7043. This information may also be examined 
at the Federal Aviation Administration (FAA), Central Region, Office of 
the Regional Counsel, Attention: Rules Docket No. 97-CE-86-AD, Room 
1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at the Office 
of the Federal Register, 800 North Capitol Street, NW, suite 700, 
Washington, DC.

FOR FURTHER INFORMATION CONTACT: Mr. Randy Griffith, Aerospace 
Engineer, FAA, Wichita Aircraft Certification Office, Room 100, 1801

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This AD

    A proposal to amend part 39 of the Federal Aviation Regulations (14 
CFR part 39) to include an AD that would apply to Raytheon Model 1900D

[[Page 34564]]

airplanes was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on February 2, 1998 (63 FR 3278). The NPRM proposed 
to require modifying the airplane by incorporating Raytheon Kit No. 
129-5200-1, ``Ground Fine Switch Installation Kit''. Accomplishment of 
the proposed action as specified in the NPRM would be in accordance 
with Raytheon Aircraft Mandatory Service Bulletin No. 2714, Issued: 
June, 1997.
    The NPRM was the result of design analysis during certification of 
5.5 degree approach landings of the Model 1900D airplanes.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. The comments received on the proposed 
rule have been given due consideration.
    The manufacturer, Raytheon Aircraft Company, states that the 
``Ground Fine Switch Installation Kit'' number is wrong. The kit number 
cited in the NPRM was P129-5200-1. Raytheon states that the ``P'' in 
front of the number was used to indicate ``prototype'' during the 
approval process. The actual kit number should be 129-5200-1. The FAA 
concurs and will remove the ``P'' on all references to Raytheon Kit No. 
P129-5200-1 in the preamble and body of the AD.
    The other comment received was from the Air Line Pilots Association 
(ALPA). ALPA concurs with the actions in the proposed AD.

The FAA's Determination

    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
the corrections mentioned above and minor editorial corrections. The 
FAA has determined that these corrections will not change the meaning 
of the AD and will not add any additional burden upon the public than 
was already proposed.

Cost Impact

    The FAA estimates that 271 airplanes in the U.S. registry will be 
affected by this AD, that it will take approximately 4 workhours per 
airplane to accomplish this action, and that the average labor rate is 
approximately $60 an hour. Raytheon is providing the kit and labor at 
no cost to the owners/operators under their Warranty Credit program for 
12 months after the last day of the month that the manufacturer's 
service bulletin was issued. If there were no warranty on the parts and 
labor to accomplish this action, the cost for U.S. operators is 
estimated to be $65,040 or $240 per airplane. This figure is based on 
the assumption that no affected operators have accomplished this 
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 
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 a new airworthiness directive

    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 within the next 800 hours time-in-service 
(TIS) after the effective date of this AD, unless already 
accomplished.
    To prevent a loose or misrigged ground fine switch, which could 
result in very hard landings causing structural damage to the 
airplane and possible passenger injury, accomplish the following:
    (a) Modify the ground idle low pitch stop system on the airplane 
by incorporating Raytheon ``Ground Fine Switch Installation Kit'' 
No. 129-5200-1 in accordance with the Accomplishment Instructions 
section of Raytheon Aircraft Mandatory Service Bulletin No. 2714, 
Issued: June, 1997.
    (b) 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.
    (c) 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), Room 100, 1801 Airport Rd., 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 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Wichita Aircraft Certification Office.

    (d) The modification required by this AD shall be done in 
accordance with Raytheon Aircraft Mandatory Service Bulletin No. 
2714, Issued: June, 1997. 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 
Raytheon Aircraft Company, P. O. Box 85, Wichita, Kansas 67201-0085.
