Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2014–20– 

01, for certain Bombardier, Inc. Model 

CL–600–2B16 (CL–601–3A, CL–601–3R, 

and CL–604 Variants) airplanes. AD 

2014–20–01 currently requires 

repetitive inspections for any fuel leak 

in the right-hand landing lights 

compartment, and related investigative 

and corrective actions if necessary. AD 

2014–20–01 also provides for an 

optional replacement of the connector of 

the fuel boost pump canister of the 

auxiliary power unit (APU), which 

terminates the repetitive inspections. 

Since we issued AD 2014–20–01, we 

have determined that a terminating 

action for the repetitive inspections is 

necessary. This proposed AD would 

retain the repetitive inspections for any 

fuel leak in the right-hand landing lights 

compartment and the related 

investigative and corrective actions, and 

would require replacing the connector 

of the fuel boost pump canister of the 

APU. We are proposing this AD to 

detect and correct fuel leaks in the righthand landing lights compartment, 

which, in combination with the heat 

generated by the taxi lights and landing 

lights on the ground reaching the autoignition temperature of the fuel, could 

result in ignition of any fuel or fumes 

present in the right-hand landing lights 

compartment. 

DATES: We must receive comments on 

this proposed AD by November 9, 2015.

Discussion 

On September 19, 2014, we issued AD 

2014–20–01, Amendment 39–17974 (79 

FR 59640, October 3, 2014). AD 2014– 

20–01 requires actions intended to 

address an unsafe condition on certain 

Bombardier, Inc. Model CL–600–2B16 

(CL–601–3A, CL–601–3R, and CL–604 

Variants) airplanes. The preamble of AD 

2014–20–01 specified that we 

considered the actions an interim action 

and that we were considering requiring 

‘‘a replacement of the connector of the 

fuel boost pump canister of the APU, 

and applicable corrective actions, which 

would constitute terminating action for 

the repetitive inspections required by 

this AD action.’’ 

Since we issued AD 2014–20–01, 

Amendment 39–17974 (79 FR 59640, 

October 3, 2014), we have determined 

that further rulemaking is indeed 

necessary; this proposed AD follows 

from that determination. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2014–21, 

dated July 10, 2014 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model CL– 

600–2B16 (CL–601–3A, CL–601–3R, and 

CL–604 Variants) airplanes. The MCAI 

states: 

Bombardier, Inc. has discovered fuel 

leakage in the auxiliary power unit (APU) 

fuel Boost Pump (BP) canister connector 

cavity. On some of those aeroplanes, leakage 

was also noticed at the APU fuel BP electrical 

conduit connection in the right hand landing 

light compartment. The root cause of the 

subject fuel leak is identified to be the 


tkelley on DSK3SPTVN1PROD with PROPOSALS
57544 Federal Register / Vol. 80, No. 185 / Thursday, September 24, 2015 / Proposed Rules 

improper length of the female connector 

keyway located in the fuel BP canister, 

causing a shift of the electrical harness and 

its seals. 

Available data indicates that on a hot day, 

due to the heat generated by the taxi light 

and/or landing lights on the ground, 

temperature in the landing light 

compartment can reach the fuel auto ignition 

temperature. Therefore, presence of any fuel 

in the right hand landing light compartment 

is considered to be a safety hazard [fuel or 

fumes present in the right-side landing lights 

compartment might ignite] that warrants 

mitigating action. 

In order to help mitigate the potential 

safety hazard precipitated by any fuel leakage 

in the right hand landing light compartment, 

Bombardier, Inc., has revised the Aircraft 

Flight Manual (AFM) through Temporary 

Revisions (TRs) 604/38 and 605/20 dated 16 

June 2014 to restrict the operation of Taxi 

and Landing lights on the ground. Transport 

Canada issued Emergency [Canadian] AD 

CF–2014–17 [(http://ad.easa.europa.eu/ad/

CF-2014-17) which corresponds to FAA AD 

2014–15–17, Amendment 39–17919 (79 FR 

44268, July 31, 2014] to mandate 

incorporation of the above AFM TRs. 

To address the root cause of the subject 

fuel leakage from the APU fuel boost pump 

canister wiring conduit, Bombardier, Inc. 

issued Alert Service Bulletin (ASB) A605– 

28–008 that requires periodic [repetitive 

general visual] inspection[s] for fuel leaks 

and [applicable related investigative and 

corrective actions and] eventual the 

replacement of the discrepant fuel BP 

canister connectors [including related 

investigative and corrective actions] on 

affected aeroplanes. The ASB has been 

revised to include an additional inspection of 

the new connector wiring for damage and 

this [Canadian] AD is issued to mandate the 

compliance with ASB A605–28–008 Revision 

2 requirements. 

We also included compliance times for 

the terminating action. 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– 

3634. 

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. 

The actions required by AD 2014–20– 

01, Amendment 39–17974 (79 FR 

59640, October 3, 2014), and retained in 

this proposed AD take about 2 workhours per product, at an average labor 

rate of $85 per work-hour. Required 

parts cost $0 per product. Based on 

these figures, the estimated cost of the 

actions that are required by AD 2014– 

20–01 is $170 per product. 

We also estimate that it would take 

about 22 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 $0 per product. Based 

on these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $172,040, or $1,870 per product. 

According to the manufacturer, some 

of the costs of this proposed 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 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 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.
