14 CFR Part 39

Airworthiness Directives; Short Brothers Model SD3 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Short Brothers Model SD3 series airplanes, that 
requires installing a new warning annunciator light on the central 
warning panel and revising the Normal Procedures Section of the 
Aircraft Flight Manual to provide the flightcrew with procedures 
related to the new light. This action is necessary to prevent an engine 
shut-down in icing conditions, which could result in loss of control of 
the airplane and consequent injury to flightcrew and passengers. This 
action is intended to address the identified unsafe condition.

DATES: Effective September 14, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 14, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Short Brothers, Airworthiness & Engineering Quality, PO 
Box 241, Airport Road, Belfast BT3 9DZ, Northern Ireland. This 
information may be examined at the Federal Aviation Administration 
(FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD)

[[Page 48367]]

that is applicable to all Short Brothers Model SD3 series airplanes was 
published in the Federal Register on June 2, 2004 (69 FR 31049). That 
action proposed to require installing a new warning annunciator light 
on the central warning panel and revising the Normal Procedures Section 
of the Aircraft Flight Manual to provide the flightcrew with procedures 
related to the new light.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    The FAA estimates that 125 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 30 work hours per 
airplane to accomplish the required actions, and that the average labor 
rate is $65 per work hour. Required parts will cost approximately 
$4,800 per airplane. Based on these figures, the cost impact of the AD 
on U.S. operators is estimated to be $843,750, or $6,750 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the requirements of this AD 
action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein will not have a substantial direct 
effect 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, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    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 final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
