RIN 2120-AA64


Airworthiness Directives; Raytheon Aircraft Company Beech Models 
1900, 1900C, and 1900D Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment revises Airworthiness Directive (AD) 97-15-13 
R1, which currently requires installing lubrication fittings in the 
airstair door handle and latch housing mechanisms on certain Raytheon 
Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D 
airplanes. Since issuance of AD 97-15-13 R1, Raytheon has revised the 
applicable service information to correct the reference to the number 
of parts each owner/operator of the affected airplanes should order and 
to change an incorrect reference to a maintenance manual. This AD 
retains the actions of AD 97-15-13 R1, and incorporates the revised 
service bulletin into the AD. The actions specified by this AD are 
intended to continue to prevent moisture from accumulating and freezing 
in the airstair door handle and latch housing, which could result in 
the door freezing shut and passengers not being able to evacuate the 
airplane in an emergency situation.

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 
Beech Models 1900, 1900C, and 1900D airplanes was published in the 
Federal Register as a notice of proposed rulemaking (NPRM) on October 
9, 1998 (63 FR 54393). The NPRM proposed to revise AD 97-15-13 R1, 
Amendment 39-10131 (62 FR 49426, September 22, 1997), by incorporating 
updated service information into the AD. AD 97-15-13 R1 currently 
requires installing lubrication fittings in the airstair door handle 
and latch housing mechanisms on certain Raytheon Beech Models 1900, 
1900C, and 1900D airplanes.
    Accomplishment of the actions of AD 97-15-13 R1 is required in 
accordance with Raytheon Mandatory Service Bulletin No. 2572, Issued: 
July, 1996.
    Accomplishment of the proposed installations would be required in 
accordance with Raytheon Mandatory Service Bulletin No. 2572, Issued: 
July, 1996; or Raytheon Mandatory Service Bulletin SB.2572, Issued: 
July, 1996; Revision No. 1, May, 1998.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. One comment was received in favor of 
the NPRM and no comments were received on 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 408 airplanes in the U.S. registry will be 
affected by this AD, that it will take approximately 14 workhours per 
airplane to accomplish the installation, and that the average labor 
rate is approximately $60 an hour. Parts cost approximately $50 per 
airplane. Based on these figures, the total cost impact of this AD on 
U.S. operators is estimated to be $363,120, or $890 per airplane. This 
figure is based on the presumption that no owner/operator of the 
affected airplanes has accomplished the required installation.
    This AD requires the same actions as AD 97-15-13 R1. The only 
difference is reference to Raytheon Mandatory Service Bulletin SB.2572, 
Issued: July, 1996; Revision No. 1, May, 1998. Therefore, this AD 
imposes no additional cost impact upon U.S. owners/operators of the 
affected airplanes than is already required by AD 97-15-13 R1.

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.
