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.

Airworthiness Directives; Honeywell International Inc. Air Data 
Pressure Transducers

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; removal.

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

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.

    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
