Airworthiness Directives; Raytheon Aircraft Company Model Beech 
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 Beech 
1900D airplanes that are equipped with the electric elevator trim 
option. This AD requires installing electric elevator trim servo 
covers. This AD is the result of reports of the affected airplanes 
leaving the factory without electric elevator trim servo covers 
installed. If the covers are not installed, moisture could freeze on 
parts of the electric actuator. The actions specified by this AD are 
intended to prevent failure of the electric elevator trim and 
difficulty operating the manual elevator trim caused by moisture 
freezing on parts of the electric actuator installation, which would 
result in the pilot having to apply constant pressure to the control 
wheel during flight.

DATES: Effective September 27, 1999.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 27, 1999.

ADDRESSES: Service information that applies to this AD may be obtained 
from the Raytheon Aircraft Company, PO Box 85, Wichita, Kansas 67201-
0085; telephone: (800) 625-7043 or (316) 676-4556. This information may 
also be examined at the Federal Aviation Administration (FAA), Central 
Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-
CE-123-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106;

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 certain Raytheon 
Model Beech 1900D airplanes that are equipped with the electric 
elevator trim option was published in the Federal Register as a notice 
of proposed rulemaking (NPRM) on March 3, 1999 (64 FR 10237). The NPRM 
proposed to require installing electric elevator trim servo covers. 
Accomplishment of the proposed action as specified in the NPRM would be 
required in accordance with the instructions to Raytheon Kit No. 129-
5035-1, as referenced in Raytheon Mandatory Service Bulletin SB 27-
3080, Issued: October, 1998, and Raytheon Mandatory Service Bulletin SB 
27-3080, Revision 1, Issued: December, 1998.
    The NPRM was the result of reports of the affected airplanes 
leaving the factory without electric elevator trim servo covers 
installed. If the covers are not installed, moisture could freeze on 
parts of the electric actuator.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.

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 
minor editorial corrections. The FAA has determined that these minor 
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 205 airplanes in the U.S. registry will be 
affected by this AD, that it will take approximately 5 workhours per 
airplane to accomplish the installation, and that the average labor 
rate is approximately $60 an hour. Raytheon will provide parts free of 
charge under warranty credit. Based on these figures, the total cost 
impact of this AD on U.S. operators is estimated to $61,500.
    Raytheon will also give warranty credit for labor until October 31, 
1999.

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

[[Page 43061]]

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 
(AD) to read as follows:

99-16-12  Raytheon Aircraft Company (Type Certificate No. A24CE 
formerly held by the Beech Aircraft Corporation): Amendment 39-
11247; Docket No. 98-CE-123-AD.

    Applicability: Model Beech 1900D airplanes, serial numbers UE-1 
through UE-246, certificated in any category, that incorporate the 
electric elevator trim option.

    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 600 hours time-in-service 
(TIS) after the effective date of this AD, unless already 
accomplished.
    To prevent failure of the electric elevator trim and difficulty 
operating the manual elevator trim caused by moisture freezing on 
parts of the electric actuator installation, which would result in 
the pilot having to apply constant pressure to the control wheel 
during flight, accomplish the following:
    (a) Install electric elevator trim servo covers in accordance 
with the instructions in Kit No. 129-5035-1, as referenced in

1998, and Raytheon Mandatory Service Bulletin SB 27-3080, Revision 
1, Issued: December, 1998.

    Note 2: The compliance time of this AD takes precedence over the 
compliance time specified in Raytheon Mandatory Service Bulletin SB 
27-3080, Revision 1, Issued: December, 1998.

    (b) Special flight permits may be issued in accordance with 
Secs. 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), 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.

    (d) The installation required by this AD shall be done in 
accordance with the instructions in Kit No. 129-5035-1, as 
referenced in Raytheon Mandatory Service Bulletin SB 27-3080, 
Issued: October, 1998, and Raytheon Mandatory Service Bulletin SB 
27-3080, Revision 1, Issued: December, 1998. 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 the Raytheon Aircraft Corporation, P.O. Box 85, 
Wichita, Kansas 67201-0085. Copies may be inspected at the FAA,
