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 DHC–8–102, 

–103, –106, –201, –202, –301, –311, and 

–315 airplanes. This proposed AD was 

prompted by reports of un-annunciated 

failures of the direct current (DC) starter 

generator, which caused caution 

indicators of the affected systems to 

illuminate and prompted emergency 

descents and landings. This proposed 

AD would require, for certain airplanes, 

replacing the DC generator control units 

(GCUs) with new GCUs and replacing 

the GCU label. We are proposing this 

AD to prevent a low voltage condition 

on the left main DC bus which, during 

critical phases of flight, could result in 

the loss of flight management, 

navigation, and transponder systems, 

and could affect continued safe flight. 

DATES: We must receive comments on 

this proposed AD by August 10, 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–2014–31R2, 

dated November 11, 2014 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model 

DHC–8–102, –103, –106, –201, –202, 

–301, –311, and –315 airplanes. The 

MCAI states: 

Four occurrences of un-annunciated failure 

of the No. 1 Direct Current (DC) Starter 

Generator prompted emergency descents and 

landings resulting from the illumination of 

numerous caution indications of the affected 

systems. The functionality of the affected 

systems such as Flight Management System, 

Navigation, and transponder systems, were 

reportedly reduced or lost. Investigation 

determined the failure was a result of a low 

voltage condition of the Left Main DC Bus. 

During critical phases of flight, the loss of 

these systems could affect continued safe 

flight. 

The original issue of this [Canadian] AD 

mandated the modification [replacing certain 

DC GCUs with new GCUs and replacing 

labels] which introduces generator control 

unit (GCU) undervoltage protection. 

Revision 1 of this [Canadian] AD added a 

GCU part number to the applicability of Part 

III of this [Canadian] AD, in order to ensure 

that all units are fitted with a warning label. 

Revision 2 of this [Canadian] AD corrects 

the GCU part number in the applicability of 

Part III of this [Canadian] AD. 

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– 

1985. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued the following 

service bulletins. 

• Service Bulletin 8–24–84, Revision 

D, dated April 10, 2014. This service 

information describes incorporating 

Bombardier modification summary 

(ModSum) 8Q101710 by replacing the 


Lhorne on DSK7TPTVN1PROD with PROPOSALS
36494 Federal Register / Vol. 80, No. 122 / Thursday, June 25, 2015 / Proposed Rules 

GCU with a new GCU, and replacing the 

GCU label for airplanes having certain 

Phoenix DC power GCU part numbers. 

• Service Bulletin 8–24–89, Revision 

C, dated November 4, 2014. This service 

information describes incorporating 

Bombardier ModSum 8Q101925 by 

replacing the GCU with a new GCU, and 

replacing the GCU label for airplanes 

having certain Goodrich DC power GCU 

part numbers. 

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 the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

affects 92 airplanes of U.S. registry. 

We also estimate that it would take 

about 3 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 up to $12,098 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be up to $1,136,476, or 

up to $12,353 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

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

1985; Directorate Identifier 2014–NM– 

214–AD. 

(a) Comments Due Date 

We must receive comments by August 10, 

2015. 

(b) Affected ADs

Label 

For airplanes having Phoenix DC GCU part 

number GC–1010–24–5DIV or GC–1010–24– 

5DV installed: Within 6,000 flight hours or 

36 months after the effective date of this AD,
