Airworthiness Directives; The Boeing Company Model 737-100, -200,
-200C, -300, -400, and -500 Series Airplanes
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 all Model 737-100, -200, -200C, -300, -400, and
-500 series airplanes. That AD currently requires repetitive
inspections to find cracks, fractures, or corrosion of each carriage
spindle of the left and right outboard mid-flaps, and corrective action
if necessary. That AD also currently requires repetitive gap checks of
the inboard and outboard carriage of the outboard mid-flaps to detect
fractured carriage spindles, and corrective actions if necessary. This
new AD requires any new or serviceable carriage spindle installed per
the requirements of the existing AD to meet minimum allowable diameter
measurements taken at three locations. This AD also requires new
repetitive inspections, measurements, and overhaul of the carriage
spindles, and applicable corrective actions. In addition, this AD
requires replacing any carriage spindle when it has reached its maximum
life limit. This AD results from reports of fractures that resulted
from stress corrosion and pitting along the length of the spindle and
spindle diameter, and additional reports of corrosion on the outboard
flap carriage spindles. We are issuing this AD to detect and correct
cracked, corroded, or fractured carriage spindles, and to prevent
severe flap asymmetry, which could result in reduced control or loss of
controllability of the airplane.
DATES: This AD becomes effective August 31, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of August 31,
2010.
On December 4, 2003 (68 FR 67027, December 1, 2003), the Director
of the Federal Register approved the incorporation by reference of a
certain other publication 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 2003-24-08, Amendment
39-13377 (68 FR 67027, December 1, 2003). The existing AD applies to
all Model 737-100, -200, -200C, -300, -400, and -500 series airplanes.
That NPRM was published in the Federal Register on March 1, 2010 (75 FR
9137). That NPRM proposed to continue to require repetitive gap checks
of the inboard and outboard carriage of the outboard mid-flaps to
detect fractured carriage spindles, and corrective actions if
necessary, and continue to require repetitive inspections to find
cracks, factures, or corrosion of each carriage spindle of the left and
right outboard mid-flaps. That NPRM also proposed to require any new or
serviceable carriage spindle installed per the requirements of the
existing AD to meet minimum allowable diameter measurements taken at
three locations. That NPRM proposed to require new repetitive
inspections, measurements, and overhaul of the carriage spindles, and
applicable corrective actions. In addition, that NPRM also proposed to
require replacing any carriage spindle
[[Page 43804]]
when it has reached its maximum life limit.
Actions Since Original NPRM Was Issued
Since we issued the original NPRM, there has been an in-service
event of a dual fracture of the outboard flap carriages. This event is
currently under investigation. As a result, we consider this AD to be
interim action. If final action is later identified, we might consider
further rulemaking then.
Explanation of Changes to AD
We have added paragraph (t)(4) to this final rule to provide credit
for actions done in accordance with previously issued AMOCs for
individual repairs. In paragraph (m) of this AD, we have also
referenced the most current issue of the Boeing (737) Standard Overhaul
Practices Manual for actions done as of the effective date of this AD.
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.
Support for the NPRM
Boeing supports the intent of the NPRM.
Request for Stricter Inspection and Overhaul Limits in Lieu of Life
Limits
Safair states that it has experienced only one flap carriage
spindle failure before AD 2003-24-08 was issued. Safair states that its
main concern is scrapping serviceable carriages in order to enforce the
life limits on the flap carriages. Safair states that stricter
inspections and overhaul requirements would ensure that stress and
pitting corrosion are detected and corrected, which would avoid
failures and would extend the life of the flap carriages.
We do not agree that substituting stricter inspection and overhaul
limits for life limits would address the unsafe condition. Since AD
2003-24-08 was issued, we have received many additional reports of
carriage spindle fractures, including fractures caused by fatigue.
Because of the difficulty in detecting small cracks and the rapid crack
growth in these parts, in combination with the concerns with reduced
fatigue life of reworked and overhauled parts, the most effective way
to maintain the continued operational safety of the fleet is to mandate
life limits. We have not changed the AD in regard to this issue.
Request for Clarification of Requirements to Remove Flap Carriage
KLM requests clarification concerning the requirements to remove
the carriage spindle in order to perform a detailed inspection for
corrosion, pitting, cracking, and measurement of some minimal allowable
spindle diameters. KLM points out that the times specified for this
action are the same as for the initial gap check and the nondestructive
test for new carriage spindles. KLM asks whether the removal of the
carriage spindle is required at 12,000 flight cycles, if the initial or
repetitive gap check and the non-destructive test (NDT) at the same
time are still useful. KLM further states that carriage spindles that
receive a thorough detailed inspection and have been found to be
serviceable do not require a gap check or an NDT inspection at the
times specified in the 12,000- to 20,000-flight-cycle range as
specified in Table 1 and Table 2 of Boeing Alert Service Bulletin 737-
57A1277, Revision 1, dated November 25, 2003. KLM states that the gap
checks and NDTs are still required, although at a different time
interval after completing the requirements of paragraph (o) of the
NPRM.
We agree that clarification might be necessary. Paragraph (o) of
this final rule requires the overhaul to be performed on the new
carriage spindle before the accumulation of 12,000 flight cycles.
Therefore, the new carriage spindle should not accumulate more than
11,999 flight cycles before being overhauled in order to comply with
this requirement. Paragraph (g) of this AD refers to Boeing Alert
Service Bulletin 737-57A1277, Revision 1, dated November 25, 2003, for
the compliance times for the gap checks and NDT inspections. Boeing
Alert Service Bulletin 737-57A1277, Revision 1, dated November 25,
2003, states that the gap check and NDT inspections are not required
for a new flap carriage spindle that has accumulated fewer than 12,000
flight cycles without being overhauled.
Boeing Alert Service Bulletin 737-57A1277, Revision 1, dated
November 25, 2003, requires relatively stringent gap checks and NDT
inspections for flap carriage spindles that have accumulated 12,000 or
more flight cycles on them since being overhauled. This requirement
should become obsolete as this AD requires that all spindles be
overhauled before accumulating 12,000 flight cycles since new or
overhauled.
We have not changed the AD in regard to this issue.
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 2,852 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 cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the actions required by
this AD, and that no operator would accomplish those actions in the
future if this AD were not adopted. However, we have been advised that
the carriage spindles are already being overhauled and replaced on some
affected airplanes. In addition, the replacement cycle is approximately
every 20 years. Therefore, the future economic cost impact of this rule
on U.S. operators is expected to be less than the cost impact figures
indicated above.
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.

RESTATEMENT OF CERTAIN REQUIREMENTS OF AD 2003-24-08, WITH UPDATED
SERVICE INFORMATION
Compliance Times
(g) The tables in paragraph 1.E., ``Compliance'' of Boeing Alert
Service Bulletin 737-57A1277, Revision 1, dated November 25, 2003,
specify the compliance times for paragraphs (g) through (k) of this
AD. For carriage spindles that have accumulated the number of flight
cycles or years in service specified in the ``Threshold'' column of
the tables, accomplish the gap check and nondestructive test (NDT)
and general visual inspections specified in paragraphs (h) and (j)
of this AD within the corresponding interval after December 4, 2003
(the effective date AD 2003-24-08), as specified in the ``Interval''
column. Repeat the gap check and NDT and general visual inspections
at the same intervals, except:
(1) The gap check does not have to be done at the same time as
an NDT inspection; after doing an NDT inspection, the interval for
doing the next gap check can be measured from the NDT inspection;
and
(2) As carriage spindles gain flight cycles or years in service
and move from one category in the ``Threshold'' column to another,
they are subject to the repetitive inspection intervals
corresponding to the new threshold category.
Work Package 2: Gap Check
(h) Perform a gap check of the inboard and outboard carriage of
the left and right outboard mid-flaps to determine if there is a
positive indication of a severed carriage spindle, in accordance

Service Bulletin 737-57A1218, Revision 5, dated February 9, 2009.
Parts Installation
(l) Except as provided in paragraph (i) of this AD: As of
December 4, 2003, no person may install on any airplane a carriage
spindle that has been removed as required by paragraph (i) or (k) of
this AD, unless it has been overhauled in accordance with the ``Work
Instructions'' of Boeing Alert Service Bulletin 737-57A1277,
Revision 1, dated November 25, 2003; or Boeing Alert Service
Bulletin 737-57A1218, Revision 5, dated February 9, 2009. After the
effective date of this AD, use only Boeing Alert Service Bulletin
737-57A1218, Revision 5, dated February 9, 2009. To be eligible for
installation under this paragraph, the carriage spindle must have
been overhauled in accordance with the requirements of paragraph (m)
of this AD.
(m) During accomplishment of any overhaul specified in paragraph
(l) of this AD, use the procedures specified in paragraphs (m)(1)
and (m)(2) of this AD during application of the nickel plating to
the carriage spindle in addition to those specified in Chapter 20-
42-09, Electrodeposited Nickel Plating, of the Boeing (737) Standard
Overhaul Practices Manual. As of the effective date of this AD, use
only Chapter 20-42-09, Electrodeposited Nickel Plating, of the
Boeing (737) Standard Overhaul Practices Manual, Revision 25, dated
July 1, 2009.
(1) The maximum deposition rate of the nickel plating in any one
plating/baking cycle must not exceed 0.002-inches-per-hour.
(2) Begin the hydrogen embrittlement relief bake within 10 hours
after application of the plating, or less than 24 hours after the
current was first applied to the part, whichever is first.
Exception to Reporting Recommendations in Certain Service Bulletins
(n) Although Boeing Alert Service Bulletin 737-57A1277, Revision
1, dated November 25, 2003, recommends that operators report
inspection findings to the manufacturer, this AD does not contain
such a reporting requirement.
