Airworthiness Directives; Boeing Model 737-700IGW Series 
Airplanes Modified by Supplemental Type Certificate ST09100AC-D, 
ST09104AC-D, ST09105AC-D, or ST09106AC-D

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Boeing Model 737-700IGW series airplanes modified by 
Supplemental Type Certificate (STC) ST09100AC-D, ST09104AC-D, 
ST09105AC-D, or ST09106AC-D. This AD requires modifying the passenger 
entertainment system (PES) installed by those STC's and revising the 
Airplane Flight Manual. This action is necessary to ensure that the 
flight crew is able to remove electrical power from the PES when 
necessary and is advised of appropriate procedures for such action. 
Inability to remove power from the PES during a non-normal or emergency 
situation could result in inability to control smoke or fumes in the 
airplane flight deck or cabin. This action is intended to address the 
identified unsafe condition.

DATES: Effective August 16, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of August 16, 2001.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Systems Company, Intelligence Information and 
Aircraft Integration Systems, 7500 Maehre Road, Waco, Texas 76705. This 
information may be examined at the Federal Aviation Administration 
(FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, 
SW., Renton, Washington; at the FAA, Fort Worth Airplane Certification 
Office, 2601 Meacham Blvd., Fort Worth, Texas; or at the Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
DC.

FOR FURTHER INFORMATION CONTACT: Ingrid Knox, Aerospace Engineer, ASW-
150, FAA, Fort Worth Airplane Certification Office, 2601 Meacham Blvd., 
Fort Worth, Texas 76137-4298; telephone (817) 222-5139; fax (817) 222-
5960.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all Boeing Model 737-700IGW series 
airplanes modified by Supplemental Type Certificate (STC) ST09100AC-D, 
ST09104AC-D, ST09105AC-D, or ST09106AC-D, was published in the Federal 
Register on March 2, 2001 (66 FR 13210). That action proposed to 
require modifying the passenger entertainment system installed by those 
STC's and revising the Airplane Flight Manual (AFM).

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

    After careful review of the available data, the FAA has determined 
that air safety and the public interest require the adoption of the 
rule as proposed.

Cost Impact

    There are approximately 4 Model 737-700IGW series airplanes of the 
affected design in the worldwide fleet. The FAA estimates that 2 
airplanes of U.S. registry will be affected by this AD.
    It will take approximately 141 work hours per airplane to 
accomplish the required modification, at an average labor rate of $60 
per work hour. Required parts will cost approximately $95,968 per 
airplane. Based on these figures, the cost impact of the modification 
in this AD on U.S. operators is estimated to be $208,856, or $104,428 
per airplane.
    It will take approximately 1 work hour per airplane to accomplish 
the required AFM revision, at an average labor rate of $60 per work 
hour. Based on these figures, the cost impact of the AFM revision in 
this AD on U.S. operators is estimated to be $120, or $60 per airplane.
    The cost impact figures discussed above are 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.
