# 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.                           ( print 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:
    - Are consistent with the intent that was proposed in the NPRM ( 79 FR 30498 , May 28, 2014); and
    - 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.
