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 BD–700–1A10 

and BD–700–1A11 airplanes. This 

proposed AD was prompted by reports 

of operator inability to open the main 

passenger door following severe hot 

soak conditions. This proposed AD 

would require the incorporation of a 

new configuration to the passenger door 

external handle detent to enhance the 

performance across the full range of the 

airplane operating temperatures. We are 

proposing this AD to prevent thermal 

expansion and permanent deformation 

at severe hot soak conditions, creating 

high friction between the spring pot 

housing and the slider that could result 

in inability to open the main passenger 

door and impede evacuation in the 

event of an emergency. 

DATES: We must receive comments on 

this proposed AD by February 29, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2015–03, 

dated March 13, 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– 

700–1A10 and BD–700–1A11 airplanes. 

The MCAI states: 


asabaliauskas on DSK5VPTVN1PROD with PROPOSALS
Federal Register / Vol. 81, No. 8 / Wednesday, January 13, 2016 / Proposed Rules 1585 

There have been reports where operators 

experienced an inability to open the main 

passenger door following severe hot soak 

conditions. 

Investigation determined that the nylon 

slider in the plunger assembly of the door 

handle is susceptible to thermal expansion 

and permanent deformation at severe hot 

soak conditions, creating high friction 

between the spring pot housing and the 

slider. 

This condition, if not corrected, could 

result in an inability to open the main 

passenger door and could impede evacuation 

in the event of an emergency. 

This [Canadian] AD mandates the 

incorporation of a new configuration to the 

passenger door external handle detent to 

enhance the performance across the full 

range of the aeroplanes operating 

temperatures. 

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– 

8435. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc. has issued the 

following service information: 

• Bombardier Service Bulletin 700– 

1A11–52–021, Revision 01, dated 

February 3, 2015. 

• Bombardier Service Bulletin 700– 

52–044, Revision 01, dated February 3, 

2015. 

• Bombardier Service Bulletin 700– 

52–5008, Revision 01, dated February 3, 

2015. 

• Bombardier Service Bulletin 700– 

52–6008, Revision 01, dated February 3, 

2015. 

The service information describes 

procedures to incorporate a new 

configuration to the passenger door 

external handle detent. 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. 

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 60 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 $0 per product. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 

operators to be $20,400, or $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.

require replacement of affected spoiler 

PCUs. We are proposing this AD to 

prevent cracking of the spoiler PCUs 

that could lead to the loss of multiple 

flight controls and landing gear systems.
