AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain McDonnell Douglas airplanes. The 
existing AD currently requires an initial general visual or dye 
penetrant inspection, repetitive dye penetrant inspections, and 
replacement, as necessary, of the rudder pedal bracket. The existing AD 
also currently requires, for certain airplanes, replacing the rudder 
pedal bracket assemblies with new, improved parts, which would 
terminate the repetitive inspections. For certain airplanes, this new 
AD requires initial inspection at a reduced threshold, removes an 
inspection option, and lengthens the repetitive inspection intervals. 
This AD results from reports of failures of the captain's rudder pedal 
brackets before reaching the initial inspection threshold identified in 
the existing AD. We are issuing this AD to prevent failure of the 
rudder pedal bracket assembly, which could result in the loss of rudder 
and braking control at either the captain's or first officer's 
position.

DATES: This AD becomes effective March 11, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 11, 
2008.
    On May 16, 2006 (71 FR 18201, April 11, 2006), the Director of the 
Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2006-07-25, amendment 
39-14552 (71 FR 18201, April 11, 2006). The existing AD applies to 
certain McDonnell Douglas airplanes. That NPRM was published in the 
Federal Register on August 31, 2007 (72 FR 50284). That NPRM proposed 
to retain the requirements of AD 2006-07-25. That NPRM also, for 
certain airplanes, proposed to reduce certain initial inspection 
thresholds, remove an inspection option, and lengthen certain 
repetitive inspection intervals.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments that have been 
received on the NPRM.

Request To Clarify Repetitive Inspections

    Air Transport Association (ATA), on behalf of its member American 
Airlines, requests that we clarify paragraphs (h) and (l) of the NPRM. 
These paragraphs specify repetitive inspections to continue based on 
the part number of the replaced rudder pedal bracket assemblies in 
accordance with paragraph (g) or (k) of the NPRM. The commenters state 
that the referenced rudder pedal bracket assemblies should be clarified 
to indicate that repetitive inspections apply only to rudder pedal 
bracket assemblies that are of the same part number as the ones 
inspected.
    We agree with the request for the reasons stated. The intent of the 
replacement in paragraphs (h) and (l) of the NPRM is to replace the 
rudder pedal bracket assemblies with a part that has the same part 
number as the part inspected. Therefore, we have revised paragraph (h) 
and (l) of the AD to replace the words ``new part'' with ``same part 
number as the one inspected.''

Request To Clarify Inspection Criteria in Paragraph (j) of the NPRM

    ATA, on behalf of its member ASTAR Air Cargo, requests that we 
clarify the inspection criteria in paragraph (j) of the NPRM. The 
commenters note that paragraph (j) of the NPRM specifies a special 
detailed inspection in accordance with McDonnell Douglas

[[Page 6579]]

DC-8 Alert Service Bulletin A27-273, Revision 1, dated May 16, 1989; or 
Revision 5, dated February 18, 1993. The commenters point out that the 
service bulletins do not have any inspection criteria listed.
    We agree with the commenters that the paragraph needs 
clarification. The intent of paragraph (j) of the AD is to specify a 
general visual inspection and penetrant inspection for Category 2 
airplanes in accordance with McDonnell Douglas DC-8 Alert Service 
Bulletin A27-273, Revision 1. Revision 1 of that service bulletin 
contains the inspection criteria. The intent of paragraph (j) was to 
specify a special detailed inspection for Category 4 airplanes in 
accordance with Boeing Alert Service Bulletin DC9-27A307, Revision 7, 
dated August 29, 2006. Revision 7 of that service bulletin contains the 
inspection criteria. We have revised paragraph (j) of the AD to clarify 
the requirements.

Request To Clarify Compliance Time in Paragraph (j)(1) of the NPRM

    ATA, on behalf of its member ASTAR Air Cargo, also notes that 
paragraph (j)(1) of the NPRM specifies a compliance time of within 
40,000 total landings or 30 days after the effective date of the AD, 
whichever occurs later. The commenters state that paragraph (j)(1) 
should refer instead to 40,000 total landings on the installed part.
    We agree with the commenters. McDonnell Douglas DC-8 Alert Service 
Bulletin A27-273, Revision 1, and Revision 5, specify a compliance time 
based on the accumulation of 40,000 total landings on the bracket 
assembly. We have revised paragraph (j)(1) of the AD to specify that 
the compliance time is 40,000 total landings on the installed part.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been received, and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    There are about 1,840 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD. The replacements are applicable 
only to Model DC-9-10, -20, -30, -40, and -50 series airplanes; Model 
DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) 
airplanes; and Model MD-88 airplanes.

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

    We have determined that 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

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

Requirements of AD 2006-07-25

Initial Inspection Threshold

    (g) For airplane categories 1, 3, and 4, prior to the 
accumulation of 40,000 total landings or within 30 days after July 
5, 1989 (the effective date of AD 89-14-02, amendment 39-6245, which 
was superseded by AD 2006-07-25), whichever occurs later: Perform 
either a general visual inspection, dye penetrant inspection, or 
special detailed inspection (eddy current with dye penetrant or just 
dye penetrant), as applicable, for cracking of the captain's and 
first officer's rudder pedal bracket, part numbers (P/N) 5616067 and 
5616068, respectively, in accordance with the Accomplishment 
Instructions of the applicable service bulletin specified in Table 2 
of this AD. After the effective date of this AD, only the special 
detailed inspection specified in Boeing Alert Service Bulletin DC9-
27A307, Revision 7, dated August 29, 2006, may be used for airplanes 
identified in Revision 7. For airplane category 4: Do the inspection 
required by this paragraph until the inspection required by 
paragraph (j) of this AD is accomplished.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

    (1) If an initial general visual inspection is accomplished, and 
no crack is found, perform a dye penetrant inspection of the rudder 
pedal bracket assembly within 180 days after the general visual 
inspection, and thereafter accomplish dye penetrant inspections at 
intervals not to exceed 12 months or 2,500 landings, whichever 
occurs earlier. For airplane categories 3 and 4, repeat at this 
interval until the inspection required by paragraph (k) of this AD 
is accomplished.
    (2) If an initial dye penetrant inspection is accomplished, and 
no crack is found, accomplish repetitive dye penetrant inspections 
at intervals not to exceed 12 months or 2,500 landings, whichever 
occurs earlier. For airplane categories 3 and 4, repeat at this 
interval until the inspection required by paragraph (k) of this AD 
is accomplished.
    (3) If an initial special detailed inspection is accomplished 
after the effective date of this AD, and no crack is found, repeat 
the

[[Page 6581]]

inspection in accordance with paragraph (k) of this AD.

Corrective Action

    (h) Except as provided by paragraph (l) of this AD: If any crack 
is detected during any inspection required by paragraph (g) or (j) 
of this AD, before further flight, remove and replace the rudder 
pedal bracket assembly in accordance with the service bulletin. 
Prior to the accumulation of 40,000 total landings after replacement 
with a part that has the same number as the part inspected, resume 
the repetitive inspections in accordance with paragraph (g) or (k) 
of this AD, as applicable. Doing the action required by paragraph 
(l) of this AD terminates the requirements of this paragraph for 
airplane category 4.

Terminating Action for Certain Airplanes

    (i) For airplane categories 3 and 4: Do the actions in 
paragraphs (i)(1) and (i)(2) of this AD in accordance with the 
Accomplishment Instructions of the applicable service bulletin 
specified in Table 2 of this AD.
    (1) Before the accumulation of 75,000 total landings on the 
captain's rudder pedal bracket assembly, P/N 5616067-501, or within 
60 months after May 16, 2006, whichever occurs later: Remove the 
rudder pedal bracket assembly and replace it with new, improved P/N 
5962903-501. Accomplishment of the replacement terminates the 
repetitive inspections of the captain's rudder pedal bracket 
assembly required by paragraphs (g), (h), (j), (k), and (l) of this 
AD.
    (2) Before the accumulation of 75,000 total landings on the 
first officer's rudder pedal bracket assembly, P/N 5616068-501, or 
within 60 months after May 16, 2006, whichever occurs later: Remove 
the rudder pedal bracket assembly and replace it with new, improved 
P/N 5962904-501. Accomplishment of the replacement terminates the 
repetitive inspections of the first officer's rudder pedal bracket 
assembly required by paragraphs (g), (h), (j), (k), and (l) of this 
AD.

New Requirements of This AD

Revised Initial Inspection at Reduced Threshold for Certain Airplanes

    (j) For airplane categories 2 and 4, at the applicable time 
specified in paragraph (j)(1), (j)(2) or (j)(3) of this AD: Do a 
general visual and penetrant inspection (for airplane category 2), 
and a special detailed inspection (for airplane category 4), as 
applicable, to detect cracking of the captain's and first officer's 
rudder pedal bracket, part numbers (P/N) 5616067 and 5616068, 
respectively, in accordance with the applicable service bulletin 
specified in Table 2 of this AD. Procedures for the dye penetrant 
inspection for airplane category 2 are contained only in the 
Accomplishment Instructions of McDonnell Douglas DC-8 Alert Service 
Bulletin A27-273, Revision 1, dated May 16, 1989. Procedures for the 
special detailed inspection are contained in Boeing Alert Service 
Bulletin DC9-27A307, Revision 7, dated August 29, 2006. Doing the 
applicable inspection required by this paragraph terminates the 
inspection requirements of paragraphs (g) and (h) of this AD for 
airplane category 4.
    (1) For category 2 airplanes: Before the accumulation of 40,000 
total landings on the installed part, or within 30 days after the 
effective date of this AD, whichever occurs later.
    (2) For category 4 airplanes that have accumulated fewer than 
25,000 total landings as of the effective date of this AD: Before 
the accumulation of 25,000 total landings, or within 3,000 landings 
after the effective date of this AD, whichever occurs later.
    (3) For category 4 airplanes that have accumulated 25,000 or 
more total landings as of the effective date of this AD, do the next 
inspection at the applicable time in paragraph (j)(3)(i) or 
(j)(3)(ii) of this AD.
    (i) For category 4 airplanes on which the corrective action 
specified in paragraph (h) of this AD has not been accomplished, do 
the inspection within 3,000 landings after the effective date of 
this AD.
    (ii) For category 4 airplanes on which the corrective action 
required by paragraph (h) of this AD has been accomplished, do the 
inspection at the earlier of the following: The next repetitive 
interval required by paragraph (h) of this AD; 40,000 total landings 
after doing the corrective action required by paragraph (h) of this 
AD; or 3,000 landings after the effective date of this AD.

Repetitive Inspections at Revised Interval for Certain Airplanes

    (k) For airplane categories 3 and 4: Repeat the special detailed 
inspection required by paragraph (g) or (j) of this AD thereafter at 
intervals not to exceed 3,000 landings. Doing the first repetitive 
inspection required by this paragraph terminates the repetitive 
inspection requirements of paragraph (g) of this AD for airplane 
categories 3 and 4.

Corrective Action Including Reduced Inspection Threshold for Certain 
Airplanes

    (l) For airplane category 4: If any crack is detected during any 
inspection required by paragraph (g), (j), or (k) of this AD: Before 
further flight, remove and replace the rudder pedal bracket assembly 
with a part that has the same part number as the one inspected, in 
accordance with the applicable service bulletin specified in Table 2 
of this AD. Before the accumulation of 25,000 total landings after 
replacement, resume the repetitive inspections in accordance with 
paragraph (k) of this AD. Doing the action in this paragraph 
terminates the requirements of paragraph (h) of this AD for airplane 
category 4.
