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–100–1A10 

(Challenger 300) airplanes. This AD was 

prompted by multiple reports of a short 

circuit between the heater element and 

the metal sheath of the pitot-static probe 

heater. This AD requires replacement of 

the left and right pitot-static probes with 

newly redesigned left and right pitotstatic probes. We are issuing this AD to 

prevent degradation of the heating 

ability of the pitot-static probe heater, 

resulting in erroneous airspeed 

indication during flight in icing 

conditions and consequent reduced 

controllability of the airplane. 

DATES: This AD becomes effective 

March 8, 2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 8, 2016.

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–100–1A10 (Challenger 300) 

airplanes. The NPRM published in the 

Federal Register on July 31, 2015 (80 FR 

45617). 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2015–04, dated March 17, 2015 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Bombardier, Inc. 

Model BD–100–1A10 (Challenger 300) 

airplanes. The MCAI states: 

There have been several reports where the 

pitot-static probe heater came on and 

remained on regardless of the heater control 

selected position. Investigation determined 

that the root cause is a short circuit between 

the heater element and the metal sheath. If 

not corrected, this condition may degrade the 

heating, resulting in erroneous Airspeed 

Indication when flying in icing condition 

[and consequent reduced controllability of 

the airplane]. 

This [Canadian] AD mandates the 

replacement of the pitot-static probes with a 

redesigned probe which will prevent this 

failure mode. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov/

#!documentDetail;D=FAA-2015-3140- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 45617, July 31, 2015) 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 (80 FR 

45617, July 31, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 45617, 

July 31, 2015). 

Related Service Information Under 1 

CFR Part 51 

Bombardier issued Service Bulletin 

100–34–38, dated January 9, 2014. The 

service information describes 

procedures for replacement of the left 

and right pitot-static probes with newly 

redesigned left and right pitot-static 

probes, part numbers 0856WC3 and 

0856WC4 respectively. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section. 

Costs of Compliance 

We estimate that this AD affects 126 

airplanes of U.S. registry. 

We also estimate that it will take 

about 12 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts will cost 

about $13,468 per product. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators to be 

$1,825,488, or $14,488 per product. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 


wgreen on DSK2VPTVN1PROD with RULES
5366 Federal Register / Vol. 81, No. 21 / Tuesday, February 2, 2016 / Rules and Regulations 

have included all costs in our cost 

estimate. 

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.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments prior to it becoming effective. 

However, we invite you to participate in 

this rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that resulted from 

adopting this AD. The most helpful

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit them only one time. We will file 

in the docket all comments that we 

receive, as well as a report summarizing 

each substantive public contact with 

FAA personnel concerning this 

rulemaking during the comment period. 

We will consider all the comments we 

receive and may conduct additional 

rulemaking based on those comments. 

Discussion 

We are adopting a new AD for Bell 

Model 429 helicopters with a T/R link 

part number (P/N) 429–012–112–101, 

–101FM, –103, or –103FM installed. 

This AD requires inspecting each T/R 

link bearing bore for any aluminum 

oxide corrosion and then cleaning the 

affected area of the T/R link and 

inspecting for any pitting. If there is any 

corrosion or any pitting, this AD 

requires replacing the T/R link. If there 

is no corrosion or pitting, this AD 

requires applying corrosion preventative 

sealant. This AD also requires a 

recurring inspection of the sealant, and 

repeating the inspection for corrosion 

and pitting if any sealant is missing. 

This AD was prompted by AD No. 

CF–2016–01, dated January 5, 2016, 

issued by Transport Canada, which is 

the aviation authority for Canada, to 

correct an unsafe condition for Bell 

Model 429 helicopters. Transport 

Canada advises of an incident in which 

a T/R link on a Model 429 helicopter 

failed, causing vibration and difficulty 

controlling the helicopter. According to 

Transport Canada, the failure was 

caused by a crack that had initiated at 

a corrosion pit between the roll staked 

lip of the bearing and the beveled edge 

of the link. Transport Canada further 

states deficiencies in the application of 

corrosion resistant finishes to the link 

during manufacturing caused the 

corrosion. 

This condition, if not detected, could 

result in failure of a link and loss of 

control of the helicopter. For these 

reasons, Transport Canada AD No. CF– 

2016–01 requires inspection of the T/R 

link and replacement of any link with 

corrosion. The Transport Canada AD 

also requires application of corrosion 

preventative sealant and reidentification of the T/R link. 

FAA’s Determination 

This helicopter has been approved by 

the aviation authority of Canada and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Canada, Transport 

Canada, its technical representative, has 

notified us of the unsafe condition 

described in the Canadian AD. We are 

issuing this AD because we evaluated 

all information provided by Transport 

Canada and determined the unsafe 

condition exists and is likely to exist or
