[Docket No. FAA-2007-28748; Directorate Identifier 2007-NM-115-AD; 
Amendment 39-15537; AD 2008-11-14]
RIN 2120-AA64

 
Airworthiness Directives; McDonnell Douglas Model DC-10-10F, DC-
10-30F (KC-10A and KDC-10), DC-10-40F, MD-10-10F, and MD-10-30F 
Airplanes; and Model MD-11 and MD-11F Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
McDonnell Douglas Model DC-10-10F, DC-10-30F (KC-10A and KDC-10), DC-
10-40F, MD-10-10F, and MD-10-30F airplanes; and Model MD-11 and MD-11F 
airplanes. This AD requires installation of control cable freeze 
protection by making certain changes. This AD results from reports of 
standing water on the horizontal pressure panel above the main and 
center landing gear wheel wells. We are issuing this AD to prevent the 
accumulation of ice on the flight control cables in the wheel wells. 
When the landing gear doors open or vibration in this area occurs, such 
ice accumulation could break off and can cause injury to people or 
damage to property on the ground, can affect landing gear controls and 
rear spar flight control systems, can cause damage to other control 
systems, and might cause loss of control of the airplane.

DATES: This AD is effective July 3, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 3, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-30F (KC-10A 
and KDC-10), DC-10-40F, MD-10-10F, and MD-10-30F airplanes; and Model 
MD-11 and MD-11F airplanes. That NPRM was published in the Federal 
Register on July 23, 2007 (72 FR 40094). That NPRM proposed to require 
installation of control cable freeze protection by making certain 
changes.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received from the two commenters.

Request To Delay Issuance of Final Rule

    FedEx and Boeing request that we delay issuance of the final rule 
until Boeing releases a revision to Boeing Alert Service Bulletin DC10-
27A237, dated January 9, 2007 (referred to as an appropriate source of 
service information for accomplishing the actions specified in the 
NPRM), and to Drawing SR11530052, and necessary parts are available. 
FedEx notes that Boeing released Information Notice DC10-27A237 IN 01, 
dated August 8, 2007, which indicates that the procedures specified in 
Boeing Alert Service Bulletin DC10-27A237 for Model DC-10-10F and MD-
10-10F airplanes cannot be done. Boeing states that the engineering 
provided in Drawing SR11530052, which is referred to in Boeing Alert 
Service Bulletin DC10-27A237, does not reflect the existing structural 
configuration used on Model DC-10-10F and MD-10-10F airplanes.
    Since issuance of the NPRM, we have reviewed Boeing Alert Service 
Bulletin DC10-27A237, Revision 1, dated December 20, 2007. Revision 1 
revises Drawing SR11530052 to account for different panel 
configurations on Model DC-10-10F and MD-10-10F airplanes and adds 
airplane groups for those affected airplanes. Revision 1 also removes 
Model DC-10-10 airplanes, which are not subject to the identified 
unsafe condition of this AD. No more work is necessary on Model DC-10-
30F (KC-10A and KDC-10), DC-10-40F, MD-10-10F, and MD-10-30F airplanes 
changed in accordance with Boeing Alert Service Bulletin DC10-27A237, 
dated January 9, 2007.
    Therefore, we have revised this AD to refer to Boeing Alert Service 
Bulletin DC10-27A237, Revision 1, as an appropriate source of service 
information for accomplishing the required actions and identifying the 
affected airplanes. We also have added a new paragraph (g) of this AD 
to give credit for actions done before the effective date of this AD 
according to Boeing Alert Service Bulletin DC10-27A237, dated January 
9, 2007, and redesignated subsequent paragraphs of the AD accordingly. 
In addition, we have removed Model DC-10-10

[[Page 30766]]

airplanes from the applicability of this AD.
    In addition, according to Boeing, an ample number of required parts 
will be available to modify the U.S. fleet within the compliance time. 
However, according to the provisions of paragraph (h) of the final 
rule, we may approve requests to adjust the compliance time if the 
request includes data that prove that the new compliance time would 
provide an acceptable level of safety.

Request To Add Repair for Damaged Seals

    FedEx requests that a repair for any damaged seal, part number 
ADA3211-125, be included in the NPRM or the next revision of Boeing 
Alert Service Bulletin DC10-27A237, dated January 9, 2007. FedEx notes 
that Boeing issued Information Notices DC10-27A237 IN 01 and MD11-
27A084 IN 02, both dated August 8, 2007, which indicate that a fix for 
damaged seals is forthcoming.
    We do not agree. Since issuance of Information Notices DC10-27A237 
IN 01 and MD11-27A084 IN 02, Boeing issued MD11-27A084 IN 03, dated 
December 14, 2007, and Boeing Alert Service Bulletin DC10-27A237, 
Revision 1, as described previously. Both of these documents state that 
repairs for damaged seals will be included in the DC10/MD10 Structural 
Repair Manuals (SRM). In addition, Boeing has received reports that, in 
certain cases, the seal, which is installed in accordance with Boeing 
Alert Service Bulletin DC10-27A237, is being damaged after installation 
as a result of being stepped on during maintenance. Therefore, there is 
no effect on accomplishing the requirements of this AD. We have not 
revised the AD in this regard.

Request To Provide Blanket Approval

    FedEx requests that we provide blanket approval for operators who 
modified the installation as shown in View L of Boeing Drawing 
SR11530052 (for Model DC-10-30F (KC-10A and KDC-10) and Model MD-10-30F 
airplanes) to fit Model DC-10-10F and MD-10-10F airplanes. FedEx states 
that blanket approval to modify the size, shape, and location of the 
angles and to shim would be helpful to any operators who have already 
done so.
    We do not agree. FedEx did not provide us with any data supporting 
their request for such an approval. In addition, we have determined 
that accomplishing the actions specified in Boeing Alert Service 
Bulletin DC10-27A237, Revision 1, will adequately address the 
identified unsafe condition of this AD. However, under the provisions 
of paragraph (h) of this AD, we might consider requests for approval of 
an alternative method of compliance (AMOC) if sufficient data are 
submitted to substantiate that such a design change would provide an 
acceptable level of safety. We have made no change to the AD in this 
regard.

Request To Refer to Correct Drawing

    FedEx requests that the NPRM be revised to refer to Drawing 
SR10270026, or that we verify that the incorrect drawing number (i.e., 
Drawing SR11270026) in Step 3 of the Work Instructions is corrected in 
the next revision to Boeing Alert Service Bulletin DC10-27A237, dated 
January 9, 2007.
    We do not agree to refer to the subject drawing in the AD. As 
discussed previously, we have reviewed Boeing Alert Service Bulletin 
DC10-27A237, Revision 1, and have revised this AD to include that 
service bulletin revision as an appropriate source of service 
information for accomplishing the required actions. The incorrect 
drawing number has been corrected in the service bulletin.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We also determined that 
these changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    There are about 387 airplanes of the affected design in the 
worldwide fleet. This AD affects about 283 airplanes of U.S. registry. 
The actions take about 40 work hours per airplane, at an average labor 
rate of $80 per work hour. Required parts cost about $5,896 or $6,073 
per airplane depending on the airplane configuration. Based on these 
figures, the estimated cost of the AD for U.S. operators is between 
$2,574,168 and $2,624,259, or $9,096 or $9,273 per airplane depending 
on the airplane configuration.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD 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.
    For the reasons discussed above, I certify that this AD:
    (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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
