Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2015-12-03, which applies to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2015-12-03 requires repetitive freeplay inspections and lubrication of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. Since the FAA issued AD 2015-12-03, engineering testing revealed that the force being applied to the elevator to detect excessive freeplay was insufficient. This proposed AD would continue to require certain actions in AD 2015-12-03 for certain airplanes, and would require revising the existing maintenance or inspection program, as applicable, for certain other airplanes, to incorporate a revised or new elevator freeplay maintenance procedure, as applicable. This proposed AD would also add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2015-12-03, which applies to certain The Boeing Company Model 777-200,
-200LR, -300, and -300ER series airplanes. AD 2015-12-03 requires
repetitive freeplay inspections and lubrication of the right and left
[[Page 16655]]
elevators, rudder, and rudder tab, and related investigative and
corrective actions if necessary. Since the FAA issued AD 2015-12-03,
engineering testing revealed that the force being applied to the
elevator to detect excessive freeplay was insufficient. This proposed
AD would continue to require certain actions in AD 2015-12-03 for
certain airplanes, and would require revising the existing maintenance
or inspection program, as applicable, for certain other airplanes, to
incorporate a revised or new elevator freeplay maintenance procedure,
as applicable. This proposed AD would also add airplanes to the
applicability. The FAA is proposing this AD to address the unsafe
condition on these products.

Background
The FAA issued AD 2015-12-03, Amendment 39-18176 (80 FR 34252, June
16, 2015) (AD 2015-12-03), for certain The Boeing Company Model 777-
200, -200LR, -300, and -300ER series airplanes. AD 2015-12-03 was
prompted by the manufacturer's determination that the procedure for the
rudder freeplay inspection available at the time did not properly
detect excessive freeplay in the rudder control load loop. AD 2015-12-
03 requires repetitive freeplay inspections and lubrication of the
right and left elevators, rudder, and rudder tab, and related
investigative and corrective actions if necessary. The agency issued AD
2015-12-03 to detect and correct excessive wear in the load loop
components of the control surfaces, which could lead to excessive
freeplay of the control surfaces, flutter, and consequent loss of
control of the airplane.
AD 2015-12-03 superseded AD 2007-13-05, Amendment 39-15109 (72 FR
33856, June 20, 2007).
Actions Since AD 2015-12-03 Was Issued
Since the FAA issued AD 2015-12-03, engineering testing revealed
that the force being applied to the elevator to detect excessive
freeplay was insufficient. The original bypass test setup for the power
control unit (PCU), which used a hydraulic depressurization method, was
found to be unreliable for putting the adjacent PCU into bypass mode,
and a new elevator freeplay maintenance procedure is necessary. Model
777F airplanes were not added to the applicability in AD 2015-12-03
because there was a certification maintenance requirement (CMR) task to
accomplish the freeplay inspections for those airplanes; therefore, the
FAA has determined that it is necessary for operators to revise the
maintenance or inspection program to update the elevator freeplay
procedures for Model 777F airplanes.
FAA's Determination
The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Service Bulletin 777-27-
0062, Revision 4, dated July 15, 2021. This service information
specifies procedures for changing the elevator
[[Page 16656]]
freeplay instructions by adding changes to the input force, elevator
freeplay limit, and PCU bypass test setup.
This proposed AD would also require Boeing Special Attention
Service Bulletin 777-27-0062, Revision 2, dated January 27, 2014, which
the Director of the Federal Register approved for incorporation by
reference as of July 21, 2015 (80 FR 34253, June 16, 2015).
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Proposed AD Requirements in This NPRM
This proposed AD would retain certain requirements of AD 2015-12-03
and require accomplishing the actions specified in accordance with
updated service information, including corrective actions, such as
repairs, already described for Model 777-200, -200LR, -300, and -300ER
airplanes. This proposed AD would also add Model 777F series airplanes
to the applicability. For Model 777F series airplanes, this proposed AD
would require revising the existing maintenance or inspection program,
as applicable, to incorporate a new elevator freeplay maintenance
procedure. For information on the procedures and compliance times, see
this service information at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching
for and locating Docket No. FAA-2022-0148.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 281 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition corrective
actions specified in this proposed AD.
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, the FAA estimates the average total cost per Model
777F operator to be $7,650 (90 work-hours x $85 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.
The FAA is 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
The FAA has 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
