[Docket No. FAA-2007-0227; Directorate Identifier 2007-NM-159-AD]
RIN 2120-AA64

Airworthiness Directives; Boeing Model 727 Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Boeing Model 727 airplanes. This proposed AD would require
repetitive inspections for cracking or corrosion of the threaded end of
the lower segment of the main landing gear (MLG) side strut, and
corrective actions if necessary. This proposed AD also would require
prior or concurrent inspection for cracking or corrosion of the threads
and thread relief area of the lower segment, corrective action if
necessary, and re-assembly using corrosion inhibiting compound. This
proposed AD results from reports of the threads cracking on the MLG
side strut lower segment. We are proposing this AD to prevent a
fractured side strut, which could result in collapse of the MLG.

DATES: We must receive comments on this proposed AD by January 10,
2008.

Discussion

    We have received many reports of the threads cracking on the main
landing gear (MLG) side strut lower segment, on Boeing Model 727
airplanes. In one instance an operator reported hearing a loud noise
during taxiing after landing. The subsequent inspection revealed the
MLG side strut was broken at the threaded end of the lower segment,
causing the side strut to become detached from the shock strut. This
condition, if not corrected, could result in collapse of the MLG.

Relevant Service Information

    We have reviewed Boeing Special Attention Service Bulletin 727-32-
0338, Revision 4, dated April 7, 2007. The service bulletin describes
procedures for repetitive detailed and magnetic particle inspections
for cracking or corrosion of the threaded end of the lower segment of
the MLG side strut. The service bulletin also describes procedures for
corrective actions for corrosion or cracking. The corrective actions
include replacing the part with a serviceable part, repairing the part
as given in the Boeing Model 727 Overhaul Manual (OHM) 32-13-01, and
doing a modification of the lower segment. There are five
configurations for modification:
     Option I Configuration--Blending out cracks and doing
thread root radiusing. This modification applies only to airplanes with
maximum taxi gross weight of 191,000 pounds and below.
     Option II Configuration--Installing a new retainer nut,
locknut, lock washer, and seals. This modification applies only to
airplanes on which the segment is crack-free.
     Option III Configuration--Removing 0.8-inch of the lower
end of the lower segment, inserting a spacer, and replacing the
retainer nut, locknut, lock washer, and seals.
     Option IV Configuration--Similar to Option III, but also
removing additional lubrication on the retainer nut; and applying
corrosion inhibiting compound, rather than grease, to the threads at
re-assembly.
     Option V Configuration--Replacing the side strut lower
segment with a larger-diameter spare (not production) part that has
fatigue improvement on the threads.
    Boeing Special Attention Service Bulletin 727-32-0338, Revision 4,
also recommends the prior or concurrent accomplishment of the actions
specified in the table titled ``Prior/Concurrent Service Bulletins.''
The prior/concurrent service bulletins facilitate the overhaul and
repair procedures specified in Boeing Special Attention Service
Bulletin 727-32-0338, Revision 4.

    Boeing Special Attention Service Bulletin 727-32-0338, Revision 4,
specifies that where any assembly, lubrication, or corrosion protection
procedure in a prior/concurrent service bulletin differs from those in
Boeing Special Attention Service Bulletin 727-32-0338, Revision 4,
operators should use the procedures in Boeing Special Attention Service
Bulletin 727-32-0338, Revision 4.
    Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously.

Costs of Compliance

    There are about 842 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 459 airplanes of
U.S. registry. The following table provides the estimated costs for
U.S. operators to comply with

this proposed AD. The average labor rate is $80 per work hour.

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.

    Title: Post-Challenge Year Survey--Mayors' Challenge for Safer
People and Safer Streets.
    Form Numbers:
    Type of Review: New Information Collection.
    Background: Over 220 cities are voluntarily participating in the
``Mayors' Challenge'' and through locally-driven efforts they are
improving bike/ped safety policies, infrastructure, and awareness. This
survey will collect information on the accomplishments of the Mayors'
Challenge, and will be used to identify best practices and to improve
future DOT outreach to cities. Each city has already identified a
point-of-contact for the Mayors' Challenge. This survey will be
distributed electronically to these POCs through an online survey tool.
    Respondents: The survey will be completed by points-of-contacts
identified in the city agencies participating in the Mayors' Challenge.
    Number of Respondents: 230 cities have volunteered to participate
in the Mayors' Challenge.
    Frequency: Once, upon completion of this challenge.
    Number of Annual Responses: 1.
    Total Annual Hour Burden: 30 minutes/respondent; Cumulative 115
hours.
    Total Annual Cost Burden: $3,388 (Based on an assumption that this
would be completed by someone at an equivalent to a GS-12 level of
seniority, which is $29.46/hour.).

Synopsis of Information Collection

    DOT will survey the cities who have volunteered to participate in
the Mayors' Challenge for Safer People and Safer Streets about their

    (2) Identify and address barriers;
    (3) Gather and track data;
    (4) Use context-sensitive designs;
    (5) Complete bike-ped networks;
    (6) Improve laws and regulations; and
    (7) Educate and enforce proper road use.
    2. What were the primary challenges and obstacles to bicycle and
pedestrian safety in your community, and what if any actions did you
take to address these challenges and obstacles?
    3. What if any changes have resulted from the challenge activities,
including changes to physical infrastructure, decision-making
processes, policies or procedures, enforcement, and education and
awareness of your community?
    4. Please use the following table to indicate whether you have data
