We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes equipped with General Electric engines. This AD was prompted by reports of cracking in barrel nuts on a forward engine mount of Model 747-8 airplanes, which shares a similar design to the forward engine mount of Model 787- 8 and 787-9 airplanes. This AD requires, for certain airplanes, replacement of the four barrel nuts of the forward engine mount on each engine. For certain other airplanes, this AD requires an inspection to determine if any forward engine mount barrel nut having a certain part number is installed; and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct cracking of the forward engine mount barrel nuts. Such cracking could result in reduced load capacity of the forward engine mount and could result in separation of an engine from the airplane and consequent loss of control of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 and 787-9 airplanes equipped with 
General Electric engines. This AD was prompted by reports of cracking 
in barrel nuts on a forward engine mount of Model 747-8 airplanes, 
which shares a similar design to the forward engine mount of Model 787-
8 and 787-9 airplanes. This AD requires, for certain airplanes, 
replacement of the four barrel nuts of the forward engine mount on each 
engine. For certain other airplanes, this AD requires an inspection to 
determine if any forward engine mount barrel nut having a certain part 
number is installed; and related investigative and corrective actions 
if necessary. We are issuing this AD to detect and correct cracking of 
the forward engine mount barrel nuts. Such cracking could result in 
reduced load capacity of the forward engine mount and could result in 
separation of an engine from the airplane and consequent loss of 
control of the airplane.

DATES: This AD is effective June 24, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 24, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company 
Model 787-8 and 787-9 airplanes equipped with General Electric engines. 
The NPRM published in the Federal Register on December 11, 2015 (80 FR 
76878) (``the NPRM''). The NPRM was prompted by reports of cracking in 
barrel nuts on a forward engine mount of Model 747-8 airplanes, which 
shares a similar design to the forward engine mount of Model 787-8 and 
787-9 airplanes. The NPRM proposed to require, for certain airplanes, 
replacement of the four barrel nuts of the forward engine mount on each 
engine. For certain other airplanes, the NPRM proposed to require an 
inspection to determine if any forward engine mount barrel nut having a 
certain part number is installed; and related investigative and 
corrective actions if necessary. We are issuing this AD to detect and 
correct cracking of the forward engine mount barrel nuts. Such cracking 
could result in reduced load capacity of the forward engine mount and 
could result in separation of an engine from the airplane and 
consequent loss of control of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to the comment.

Request To Revise the Compliance Time

    United Airlines requested that the compliance time in the NPRM for 
Group 1 airplanes be changed from 2 years to ``at next engine change.'' 
United considered the proposed compliance time to be ``expedited'' 
because it took Boeing 7 months to publish the service information 
operators would be required to use to comply with the requirements in 
the NPRM, and it took

[[Page 31849]]

the FAA 6 months to publish the NPRM. The commenter reasoned that since 
it took over 1 year from the time a solution for the unsafe condition 
was identified to the publication of the NPRM, the timeline for 
completing the corrective action is not critical and could be 
accomplished at the next scheduled engine change. United Airlines 
explained that allowing operators to replace the forward barrel nuts at 
the next engine change would reduce the cost of compliance to zero and 
would not add additional burden to operators.
    We do not agree with the commenter's request. In developing an 
appropriate compliance time for this action we considered not only the 
degree of urgency associated with addressing the subject unsafe 
condition, but the manufacturer's recommendation for an appropriate 
compliance time, the time required for the rulemaking process, and the 
practical aspect of doing the required replacement within an interval 
of time that corresponds to the typical scheduled maintenance for the 
majority of affected operators. However, under the provisions of 
paragraph (j) of this AD, we will consider requests for approval of an 
extension of the compliance time if sufficient data are submitted to 
substantiate that the new compliance time would provide an acceptable 
level of safety. We have not changed the AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed, except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin B787-81205-SB710026-00, Issue 
001, dated June 10, 2015. The service information describes procedures 
for replacing the forward engine mount barrel nuts with new, improved 
barrel nuts; doing an inspection to determine if barrel nuts having a 
certain part number are installed on the forward engine mount; and 
doing related investigative and corrective actions. 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.

Costs of Compliance

    We estimate that this AD affects 36 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                     Cost per
            Action                Labor cost        Parts cost        product         Cost on U.S.  operators

                                engines.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any related investigative 
actions required based on the results of the inspection. We have no way 
of determining the number of aircraft that might need these actions:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

Inspection (2 engines).......................  9 work-hours x $85 per hour =                $0             $765
                                                $765 for 2 engines.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that will enable us to provide 
cost estimates for the on-condition corrective actions specified in 
this AD.
    According to the manufacturer, some of the costs of this AD may 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

    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),
    (3) Will not affect intrastate aviation in Alaska, and

[[Page 31850]]

    (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.
