Federal Register Abstract
We are removing Airworthiness Directive (AD) 2012-26-15, which applied to certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. AD 2012-26-15 required doing various tests or checks of equipment having certain air data pressure transducers, removing equipment if necessary, and reporting the results of the tests or checks. As an option to the tests or checks, AD 2012-26-15 allowed removal of affected equipment having certain air data pressure transducers. We issued AD 2012-26-15 to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. AD 2012-26-15 reported that these errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. Since we issued AD 2012-26-15, we have received new data indicating that the safety risk is lower than originally estimated.

SUMMARY: We are removing Airworthiness Directive (AD) 2012-26-15, which
applied to certain Honeywell International Inc. air data pressure
transducers as installed on various aircraft. AD 2012-26-15 required
doing various tests or checks of equipment having certain air data
pressure transducers, removing equipment if necessary, and reporting
the results of the tests or checks. As an option to the tests or
checks, AD 2012-26-15 allowed removal of affected equipment having
certain air data pressure transducers. We issued AD 2012-26-15 to
detect and correct inaccuracies of the pressure sensors, which could
result in altitude, computed airspeed, true airspeed, and Mach
computation errors. AD 2012-26-15 reported that these errors could
reduce the ability of the flightcrew to maintain the safe flight of the
aircraft and could result in consequent loss of control of the
aircraft. Since we issued AD 2012-26-15, we have received new data
indicating that the safety risk is lower than originally estimated.
DATES: This AD becomes effective December 3, 2014.

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 Honeywell
International Inc. air data pressure transducers as installed on
various aircraft. The NPRM published in the Federal Register on May 28,
2014 (79 FR 30498). The NPRM was prompted by new data indicating that
the safety risk is lower than originally estimated. The NPRM proposed
to remove AD 2012-26-15, Amendment 39-17310 (78 FR 1735, January 9,
2013).
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received.
[[Page 64306]]
Boeing concurred with the NPRM (79 FR 30498, May 28, 2014).
Conclusion
We reviewed the available data, including 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (79 FR 30498, May 28, 2014); and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 30498, May 28, 2014).
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.
Regulatory Findings
We 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 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.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://www.regulations.gov/#!docketDetail">http://www.regulations.gov/#!docketDetail</a>;D=FAA-2014-0285; or in person at the
Docket Management Facility between 9 a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The AD docket contains this AD, any
comments received, and other information. The street address for the
