Identifier 2015–NM–104–AD]

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) 

airplanes, Model CL–600–2D15 

(Regional Jet Series 705) airplanes, 

Model CL–600–2D24 (Regional Jet 

Series 900) airplanes, and Model CL– 

600–2E25 (Regional Jet Series 1000) 

airplanes. This proposed AD was 

prompted by the discovery of a number 

of incorrectly calibrated angle of attack 

(AOA) transducers installed in the stall 

protection system. This proposed AD 

would require replacement of affected 

AOA transducers. We are proposing this 

AD to detect and replace incorrectly 

calibrated AOA transducers; incorrect 

calibration of the transducers could 

result in late activation of the stick 

pusher. 

DATES: We must receive comments on 

this proposed AD by December 28, 

2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2015–18, 

effective July 16, 2015 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–2C10 (Regional Jet Series 700, 701, 

& 702) airplanes, Model CL–600–2D15 

(Regional Jet Series 705) airplanes, 

Model CL–600–2D24 (Regional Jet 

Series 900) airplanes, and Model CL– 

600–2E25 (Regional Jet Series 1000) 

airplanes. The MCAI states: 

It was discovered that a number of [angle 

of attack] AOA transducers installed on 

Bombardier CL–600–2C10, CL–600–2D15, 

CL–600–2D24, and CL–600–2E25 aeroplanes 

were incorrectly calibrated due to a quality 

control problem at both the production and 

repair facilities. Incorrect calibration of the 

AOA transducer could result in a late 

activation of the stick pusher. 

This [Canadian] AD mandates the 

replacement of the incorrectly calibrated 

AOA transducer. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

4811. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc. has issued 

Bombardier Service Bulletin 670BA–27– 

069, dated March 30, 2015. The service 

information describes procedures for 

replacement of the transducers with 

correctly calibrated AOA transducers. 

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 of 

this NPRM. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of these same 

type designs.

Federal Register / Vol. 80, No. 218 / Thursday, November 12, 2015 / Proposed Rules 69897 

Costs of Compliance 

We estimate that this proposed AD 

affects 400 airplanes of U.S. registry. 

We also estimate that it would take 

about 4 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $10,000 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $4,136,000, or 

$10,340 per product. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

Bombardier, Inc.: Docket No. FAA–2015– 

4811; Directorate Identifier 2015–NM– 

104–AD.

Series 700, 701, & 702) airplanes, serial 

numbers 10002 through 10999 inclusive. 

(2) Model CL–600–2D15 (Regional Jet

stall protection system. We are issuing this 

AD to detect and replace incorrectly 

calibrated AOA transducers; incorrect 

calibration of the transducers could result in 

late activation of the stick pusher.

compliance times specified, unless already 

done. 

(g) Replacement 

Within 2,500 flight hours or 12 months,

Bombardier Service Bulletin 670BA–27–069, 

dated March 30, 2015, with correctly 

calibrated AOA transducers, in accordance 

with the Accomplishment Instructions of 

Bombardier Service Bulletin 670BA–27–069, 

dated March 30, 2015. 

(h) Parts Installation Prohibition 

As of the effective date of this AD, no 

person may install, on any airplane, an AOA 

transducer having a part number or serial 

number identified in paragraph 1.A., 

‘‘Effectivity,’’ of Bombardier Service Bulletin 

670BA–27–069, dated March 30, 2015. 

(i) Other FAA AD Provisions
