AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model BD–700–1A10 

airplanes. This AD was prompted by a 

report that the manufacturer has 

determined that some completion 

centers used the heater/brake 

monitoring unit (HBMU) logic circuit to 

control the line voltage of the drain mast 

heaters. Since the drain mast heaters are 

connected in parallel with the number 

2 pitot static (PS) probe heater circuit, 

a number 2 PS probe heater failure may 

not be detected by the fault monitoring 

capabilities of the HBMU. This AD 

requires modification of the air data 

probes and sensors. We are issuing this 

AD to detect and correct an 

unannunciated failure of two PS probe 

heaters, which could affect 

controllability of the airplane in icing 

conditions. 

DATES: This AD becomes effective April 

1, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 1, 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 Bombardier, Inc. Model 

BD–700–1A10 airplanes. The NPRM 

published in the Federal Register on 

September 11, 2013 (78 FR 55660). The 

NPRM was prompted by a report that 

the manufacturer has determined that 

some completion centers used the 

heater/brake monitoring unit (HBMU) 

logic circuit to control the line voltage 

of the drain mast heaters. Since the 

drain mast heaters are connected in 

parallel with the number 2 pitot static 

(PS) probe heater circuit, a number 2 PS 

probe heater failure may not be detected 

by the fault monitoring capabilities of 

the HBMU. The NPRM proposed to 

require modification of the air data 

probes and sensors. We are issuing this 

AD to detect and correct an 

unannunciated failure of two PS probe 

heaters, which could affect 

controllability of the airplane in icing 

conditions. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2012–32, 

dated December 13, 2013 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

The aeroplane manufacturer has 

determined that some completion centers 

used the Heater/Brake Monitoring Unit 

(HBMU) logic circuit to control the line 

voltage of the drain mast heaters. This same 

logic circuit is also used to control the line 

voltage of the number 2 pitot static (PS) 

probe heater. Since the drain mast heaters are 

connected in parallel with the number 2 PS 

probe heater circuit, a number 2 PS probe 

heater failure may not be detected by the 

fault monitoring capabilities of the HBMU. 

The unannunciated failure of two PS probe 

heaters could adversely affect the aeroplane’s 

flight characteristics in icing conditions. 

This [Canadian] AD mandates a 

modification to the existing drain mast heater 

wiring to correct the fault-monitoring 

capabilities of the HBMU and eliminate the 

potential dormant failure of the number 2 PS 

probe heater. 

You may examine the MCAI in the 

AD docket on the Internet at http://

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 55660, September 11, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data 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 (78 FR 

55660, September 11, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 55660, 

September 11, 2013). 

Costs of Compliance 

We estimate that this AD affects 32 

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 

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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Agusta 

S.p.A. (Agusta) Model AB412 

helicopters. This AD requires visually 

inspecting the main rotor swashplate 

outer ring (outer ring) for a crack and 

replacing that outer ring if a crack 

exists. This AD is prompted by two 

cases of cracks caused by fatigue on 

certain outer rings. These actions are 

intended to prevent the failure of the 

outer ring, which would lead to loss of 

main rotor blade pitch control and 

subsequently loss of helicopter control. 

DATES: This AD becomes effective 

March 12, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD
