RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede two existing airworthiness directives
(AD) that apply to all The Boeing Company Model 767 airplanes. One AD
currently requires a functional check of the shear rivets in all six
elevator power control actuator (PCA) bellcrank assemblies to determine
the condition of the shear rivets, and replacement or rework of the
bellcrank assemblies if necessary. The other AD currently requires
repetitive testing of the elevator control system to determine if an
elevator PCA is rigged incorrectly, and follow-on actions if necessary.
Since we issued those ADs, a terminating modification has been
designed. This proposed AD would require an inspection to determine the
part numbers and condition of the bellcrank assemblies; modification or
replacement of the PCA bellcrank assembly, if necessary; and a
repetitive functional test and mis-rig check, and corrective actions if
necessary. We are proposing this AD to prevent continued operation with
yielded or failed shear rivets in the elevator PCA bellcrank
assemblies, and to prevent certain failures or jams in the elevator
system from causing a hardover of the elevator surface, resulting in a
significant pitch upset and possible loss of control of the airplane.
DATES: We must receive comments on this proposed AD by April 12, 2013.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
On August 18, 2000, we issued AD 2000-17-05, Amendment 39-11879 (65
FR 51754, August 25, 2000), for certain The Boeing Company Model 767-
200, -300, and -300F series airplanes. That AD requires a one-time
functional check of the shear rivets in all six PCA bellcrank
assemblies to determine the condition of the shear rivets; and
replacement or rework of the bellcrank assemblies, if necessary. That
AD resulted from reports that elevator bellcrank assemblies with failed
shear rivets had been found on three Model 767 airplanes. We issued
that AD to detect and correct any failed or partially yielded shear
rivets of the elevator PCA bellcrank assemblies. Failure of two
bellcrank assemblies on one side can result in that single elevator
surface moving to a hardover position, independent of pilot command,
resulting in a significant pitch upset recoverable by the crew. Failure
of three bellcrank assemblies on one side could result in loss of
control of the airplane.
On February 21, 2001, we issued AD 2001-04-09, Amendment 39-12128
(66 FR 13227, March 5, 2001), for all The Boeing Company Model 767
airplanes. That AD requires repetitive testing of the elevator control
system to determine if an elevator PCA is rigged incorrectly due to
yielded or failed shear rivets in a bellcrank assembly of the elevator
PCA, and follow-on actions if necessary. That AD resulted from reports
that several Model 767 airplanes failed the one-time functional check
of the shear rivets in the bellcrank assemblies of the elevator PCA
required by AD 2000-17-05, Amendment 39-11879 (65 FR 51754, August 25,
2000). We issued AD 2001-04-09, Amendment 39-12128 (66 FR 13227, March
5, 2001), to prevent continued operation with yielded or failed shear
rivets in a bellcrank assembly of the elevator PCA, which could result
in loss of control of the airplane.
Actions Since Existing AD 2000-17-05, Amendment 39-11879 (65 FR 51754,
August 25, 2000); and AD 2001-04-09, Amendment 39-12128 (66 FR 13227,
March 5, 2001) Issued
The preambles to AD 2000-17-05, Amendment 39-11879 (65 FR 51754,
August 25, 2000); and AD 2001-04-09, Amendment 39-12128 (66 FR 13227,
[[Page 12992]]
March 5, 2001); specify that we consider the requirements ``interim
action.'' Those ADs explain that we might consider further rulemaking
if a modification is developed, approved, and available. The
manufacturer now has developed such a modification, and we have
determined that further rulemaking is indeed necessary; this proposed
AD follows from that determination.
Relevant Service Information
We reviewed Boeing Service Bulletins 767-27-0186, dated June 25,
2007 (for Model 767-200, -300, and -300F series airplanes); and 767-27-
0187, dated June 25, 2007 (for Model 767-400ER series airplanes). This
service information describes procedures for doing a general visual
inspection of the PCA bellcrank assemblies on each elevator to
determine if the bellcrank assembly has shear rivets; and installing a
solid elevator PCA bellcrank assembly or reworking the bellcrank
assembly to replace the shear rivets with solid rivets, if necessary.
This service information also describes procedures for the initial test
of the elevator PCA input rod assemblies (pogo check), and replacement
or overhaul if necessary; and an elevator PCA rigging check.
We also reviewed Boeing Service Bulletins 767-27-0200, dated June
25, 2007 (for Model 767-200, -300, and -300F series airplanes); and
767-27-0201, dated June 27, 2007 (for Model 767-400ER series
airplanes). This service information describes procedures for
repetitive testing of the elevator PCA input rod assemblies (pogo
check), and replacing or overhauling the elevator PCA input rod
assembly, if necessary.
We reviewed Boeing Service Bulletins 767-27-0202, Revision 1, dated
February 21, 2008 (for Model 767-200, -300, and -300F series
airplanes); and 767-27-0203, Revision 1, dated February 21, 2008 (for
Model 767-400ER series airplanes). This service information describes
procedures for doing repetitive checks of the elevator PCA rigging, and
adjusting the PCA input rod assemblies and structural inspection, if
necessary.
Other Relevant Rulemaking
AD 2007-24-08, Amendment 39-15274 (72 FR 67236, November 28, 2007),
was issued for Model 767 airplanes. That AD requires repetitive
measurements of the rudder and elevator freeplay, related investigative
and corrective actions if necessary, and repetitive lubrications of the
rudder and elevator components. For certain airplanes, we require
concurrent actions.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain certain requirements of AD 2000-17-
05, Amendment 39-11879 (65 FR 51754, August 25, 2000); and AD 2001-04-
09, Amendment 39-12128 (66 FR 13227, March 5, 2001). This proposed AD
would require an inspection to determine the part numbers and condition
of the bellcrank assemblies; modification or replacement of the PCA
bellcrank assembly, if necessary; and repetitive post-modification
testing and corrective actions, if necessary. This proposed AD would
also require accomplishing the actions specified in the service
information described previously, except as discussed under
``Differences Between the Proposed AD and the Service Information.''
Change to Existing AD 2001-04-09 (66 FR 13227, March 5, 2001) and AD
2000-17-05, Amendment 39-11879 (65 FR 51754, August 25, 2000)
Boeing Commercial Airplanes has received an Organization
Designation Authorization (ODA). We have revised this proposed AD to
delegate the authority to approve an alternative method of compliance
for any repair required by this proposed AD to the Boeing Commercial
Airplanes ODA rather than a Designated Engineering Representative
(DER).
Since AD 2000-17-05, Amendment 39-11879 (65 FR 51754, August 25,
2000); and AD 2001-04-09, Amendment 39-12128 (66 FR 13227, March 5,
2001); were issued, the AD format has been revised, and certain
paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:

------------------------------------------------------------------------
In addition, we have revised certain headings pertaining to
restated material throughout this AD.
Differences Between the Proposed AD and the Service Information
This proposed AD will allow for an alternate grease (BMS 3-33) when
accomplishing the actions specified in Boeing Service Bulletins 767-27-
0186 and 767-27-0187, both dated June 25, 2007.
Although Boeing Service Bulletins 767-27-0202 and 767-27-0203, both
Revision 1, both dated February 21, 2008, do not specify a corrective
action following a structural inspection, this proposed AD would
require operators to repair conditions using a method approved by the
FAA.
Costs of Compliance
We estimate that this proposed AD affects 415 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

--------------------------------------------------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary repairs or
replacements that would be required based on the results of the
proposed inspection, tests, and checks. We have no way of determining
the number of aircraft that might need these repairs or replacements.
We estimate that reworking the bellcrank assembly would take about
6 work-hours, for a labor cost of $510 per airplane; however, we have
no definitive data to determine the cost of parts required. We have
received no definitive data that would enable us to provide a cost
estimate for replacing or overhauling the elevator PCA input rod
assembly, adjusting the elevator PCA input rod assemblies, and doing
structural inspections specified in this proposed AD.
According to the manufacturer, some of the costs of this proposed
AD might be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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 are issuing this AD to prevent continued operation with yielded
or failed shear rivets in the elevator PCA bellcrank assemblies, and
to prevent certain failures or jams in the elevator system from
causing a hardover of the elevator surface, resulting in a
significant pitch upset and possible loss of control of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Functional Check
This paragraph restates the requirements of paragraph (a) of AD
2000-17-05, Amendment 39-11879 (65 FR 51754, August 25, 2000). For
Model 767-200, -300, and -300F series airplanes, line numbers 1
through 800 inclusive: Within 30 days after September 11, 2000 (the
effective date AD 2000-17-05), perform a functional check of one
shear rivet in all six elevator PCA bellcrank assemblies to
determine the condition of the shear rivets, in accordance with
Paragraph 3 of the Accomplishment Instructions of Boeing Alert
Service Bulletin 767-27A0166, dated August 17, 2000. Doing the
actions required by paragraphs (j), (k), and (l) of this AD
terminates the requirements of paragraph (g) of this AD.
(1) If all penetration depths, when measured per Figure 2 of
Boeing Alert Service Bulletin 767-27A0166, dated August 17, 2000,
are 0.50 inch or more, no further action is required by paragraph
(g) of this AD.
(2) If any penetration depth, when measured per Figure 2 of
Boeing Alert Service Bulletin 767-27A0166, dated August 17, 2000, is
0.35 inch or more, but less than 0.50 inch, rework or replace the
bellcrank assembly with a new or serviceable bellcrank assembly
within 400 flight hours after accomplishing the functional check.
After installation of a new or serviceable bellcrank assembly, and
prior to further flight, repeat the functional check of all the
bellcrank assemblies to make sure the rivets are still in good
condition (as specified in Boeing Alert Service Bulletin 767-
27A0166, dated August 17, 2000) after installation, in accordance
with Figure 2 of Boeing Alert Service Bulletin 767-27A0166, dated
August 17, 2000.
(3) If any penetration depth, when measured per Figure 2 of
Boeing Alert Service Bulletin 767-27A0166, dated August 17, 2000, is
less than 0.35 inch, prior to further flight, rework or replace the
bellcrank assembly with a new or serviceable bellcrank assembly.
After installation of a new or serviceable bellcrank assembly, and
prior to further flight, repeat the functional check of all the
bellcrank assemblies to make sure the rivets are still in good
condition (as specified in Boeing Alert Service Bulletin 767-
27A0166, dated August 17, 2000) after installation, in accordance
with Figure 2 of Boeing Alert Service Bulletin 767-27A0166, dated
August 17, 2000.
(h) Retained Repetitive Tests
This paragraph restates the requirements of paragraph (a) of AD
2001-04-09, Amendment 39-12128 (66 FR 13227, March 5, 2001), with
revised provisions for repetitive tests. For all airplanes: Within
90 days after March 20, 2001 (the effective date of AD 2001-04-09),
perform a test of the elevator PCA bellcranks to determine if an
elevator PCA is rigged incorrectly due to yielded or failed shear
rivets in a bellcrank assembly, in accordance with Boeing Alert
Service Bulletin 767-27A0168 (for Model 767-200, -300, and -300F
series airplanes) or 767-27A0169 (for Model 767-400ER series
airplanes), both dated November 21, 2000. Repeat the test thereafter
at least every 400 flight hours. As of March 20, 2001 (the effective
date of AD 2001-04-09), and until the accomplishment of the actions
required by paragraphs (j), (k), and (l) of this AD, as applicable.
Accomplishment of the repetitive tests required by paragraph (h) of
this AD are acceptable for compliance with the functional check of
the elevator system required by a certification maintenance
requirement (CMR) that is documented as Item Number 27-31-00-5B in
the Boeing 767 Maintenance Planning Document (MPD). Doing the
actions required by paragraphs (j), (k), and (l) of this AD
terminates the requirements of paragraph (h) of this AD. After
accomplishment of the actions required by paragraphs (j), (k), and
(l) of this AD, accomplishment of the repetitive tests required by
paragraph (h) of this AD are not acceptable for compliance with the
functional check of the elevator system required by a CMR that is
documented as Item Number 27-31-00-5B in the Boeing 767 MPD.
(i) Retained Follow-On Actions
This paragraph restates the requirements of paragraph (b) of AD
2001-04-09, Amendment 39-12128 (66 FR 13227, March 5, 2001). For all
airplanes: If an elevator PCA is determined to be rigged incorrectly
during any test required by paragraph (h) of this AD, before further
flight, do a one-time inspection to measure penetration depth of the
shear rivets of all three elevator bellcrank assemblies of the
affected elevator surface, in accordance with Boeing Alert Service
Bulletin 767-27A0168 (for Model 767-200, -300, and -300F series
airplanes) or 767-27A0169 (for Model 767-400ER series airplanes),
both dated November 21, 2000. Doing the actions required by
paragraphs (j), (k), and (l) of this AD terminates the requirements
of paragraph (i) of this AD.
(1) If the measured penetration depth of the shear rivets on all
bellcrank assemblies is 0.50 inch or more: Before further flight,
re-rig the elevator PCA correctly, in accordance with Boeing Alert
Service Bulletin 767-27A0168 (for Model 767-200, -300, and -300F
series airplanes) or 767-27A0169 (for Model 767-400ER series
airplanes), both dated November 21, 2000.
(2) If the measured shear rivet penetration depth on any single
bellcrank assembly is less than 0.50 inch: Before further flight,
repair the bellcrank assembly by replacing the shear rivets or
replace the bellcrank assembly, and reassemble and re-rig the
elevator control system, in accordance with Boeing Alert Service
Bulletin 767-27A0168 (for Model 767-200, -300, and -300F series
airplanes) or 767-27A0169 (for Model 767-400ER series airplanes),
both dated November 21, 2000.
(j) New Inspection and Modification
For airplanes having line numbers 1 through 901 inclusive:
Within 72 months after the effective date of this AD, do a general
visual inspection of the three PCA bellcrank assemblies on each
elevator to determine the part numbers (P/Ns) of the bellcrank
assemblies and to determine whether the bellcrank assembly has shear
rivets, in accordance with the Accomplishment Instructions of Boeing
Service Bulletin 767-27-0186, dated June 25, 2007 (for Model 767-
200, -300, and -300F series airplanes); or 767-27-0187, dated June
25, 2007 (for Model 767-400ER series airplanes).
(1) If the bellcrank assembly has P/N 252T2118-4 or 252T2118-5,
and has solid rivets, no further action is required by this
paragraph.
(2) If the bellcrank is a solid one-piece bellcrank with no
rivets, no further action is required by this paragraph.
(3) If the bellcrank assembly has P/N 252T2118-1, 252T2118-2, or
252T2118-3, and has shear rivets, before further flight, do the
action specified in either paragraph (j)(3)(i) or (j)(3)(ii) of this
AD, in accordance with the Accomplishment Instructions of Boeing
Service Bulletin 767-27-0186, dated June 25, 2007 (for Model 767-
200, -300, and -300F series airplanes); or 767-27-0187, dated June
25, 2007 (for Model 767-400ER series airplanes); except as provided
by paragraph (n) of this AD.
(i) Rework the existing bellcrank to replace the shear rivets
with solid rivets.
(ii) Install a new, solid one-piece (no rivets) bellcrank
assembly having P/N 252T2118-6.
(k) New Repetitive Functional Test (Pogo Check)
(1) For airplanes having line numbers 1 through 901 inclusive:
Before further flight after doing the inspection and applicable
corrective actions required by paragraph (j) of this AD, do a
