Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-5038; Directorate Identifier 2016-NM-029-AD; 
Amendment 39-18455; AD 2016-07-10]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 787-8 and 787-9 airplanes. This AD requires 
revising the airplane flight manual (AFM) to instruct the flightcrew to 
avoid abrupt flight control inputs in response to sudden drops in 
airspeed, and to reinforce the need to disconnect the autopilot before 
making any manual flight control inputs. This AD was prompted by 
reports indicating that in certain weather conditions with high 
moisture content or possible icing, erroneous low airspeed may be 
displayed to the flightcrew before detection and annunciation via 
engine-indicating and crew-alerting system (EICAS) messages. We are 
issuing this AD to ensure that the flightcrew avoids abrupt pilot 
control inputs in response to an unrealistic, sudden drop in displayed 
airspeed at high actual airspeed. Abrupt pilot control inputs in this 
condition could exceed the structural capability of the airplane.

DATES: This AD is effective April 14, 2016.
    We must receive comments on this AD by May 16, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Discussion

    We have received three reports of in-service displayed airspeed 
anomalies on Model 787 airplanes. We continue to investigate this issue 
with Boeing; however, the anomalous behavior is consistent with 
significant water ingestion or simultaneous icing of two or three of 
the three pitot probes. During each of the reported events, the 
displayed airspeed rapidly dropped significantly below the actual 
airplane airspeed. In normal operations, the air data reference system 
supplies the same airspeed to both the captain and first officer 
primary flight displays. During one in-service event, with autopilot 
engaged, the pilot overrode the engaged autopilot in response to the 
displayed erroneous low airspeed and made significant nose-down manual 
control inputs. In this situation, there is the potential for large 
pilot control inputs at high actual airspeed, which could cause the 
airplane to exceed its structural capability.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires revising the AFM to add a ``Non-normal Procedure'' 
for ``Airspeed Drop'' that instructs the flightcrew to avoid abrupt 
flight control inputs, and reinforces the need to disconnect the 
autopilot prior to making any manual flight control inputs.

Interim Action

    We consider this AD interim action. The airplane manufacturer is 
currently developing modifications to the display and crew alerting 
system, flight control system, and air data system that will address 
the unsafe condition identified in this AD. Once these modifications 
are developed, approved, and available, we may consider additional 
rulemaking.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
large, abrupt pilot control inputs in response to an unrealistic, 
sudden drop in displayed airspeed at high actual airspeed could exceed 
the structural capability of the airplane. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about

[[Page 18742]]

this AD. Send your comments to an address listed under the ADDRESSES 
section. Include the docket number FAA-2016-5038 and Directorate 
Identifier 2016-NM-029-AD at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 43 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

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
    (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.
