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–8–400 

series airplanes. This proposed AD was 

prompted by cases of on-ground failure 

of the screw cap or end cap of hydraulic 

accumulators on other airplane models, 

resulting in high-energy impact damage 

to adjacent systems and structure. This 

proposed AD would require inspecting 

for a part number and replacing the 

affected parking brake hydraulic 

accumulator, and relocating the parking 

brake accumulator, on the subject 

airplanes. We are proposing this AD to 

prevent failure of the screw caps and/or 

end caps of the parking brake hydraulic 

accumulator, which could result in 

damage to the airplane’s primary 

structures, with potential adverse effect 

on the airplane’s controllability. 

DATES: We must receive comments on 

this proposed AD by September 17, 

2012. 

ADDRESSES: You may send comments 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–2012–04, 

dated January 13, 2012 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Seven cases of on-ground hydraulic 

accumulator/screw cap/end cap failure have 

been experienced on CL–600–2B19 (CRJ) 

aeroplanes, resulting in loss of the associated 

hydraulic system and high-energy impact 


TKELLEY on DSK3SPTVN1PROD with PROPOSALS
45982 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Proposed Rules 

damage to adjacent systems and structure. To 

date, the lowest number of flight cycles 

accumulated at the time of failure has been 

6991. 

Although there have been no failures to 

date on any DHC–8 aeroplanes, similar 

accumulators to those installed on the CL– 

600–2B19, Part Number (P/N) 08–60197–001 

(Parking Brake Accumulator), are installed on 

the aeroplanes listed in the Applicability 

section of this Airworthiness Directive (AD). 

It was also found that some of these 

accumulators may be affected by 

manufacturing non-conformances. 

A detailed analysis of the systems and 

structure in the potential line of trajectory of 

a failed screw cap/end cap for the 

accumulator has been conducted. It has been 

identified that the worst-case scenarios 

would be the damage to the aeroplane’s 

primary structures, which could have an 

adverse effect on the controllability of the 

aeroplane. 

This AD mandates the [inspection for part 

and serial numbers and] replacement of the 

affected hydraulic accumulators and the 

relocation of the parking brake accumulator. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier, Inc. has issued Service 

Bulletin 84–32–87, Revision B, dated 

November 22, 2011; and Service 

Bulletin 84–32–88, dated February 16, 

2011. Goodrich has issued Service 

Bulletin 08 60197 001–32–70 R2, dated 

February 1, 2011. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

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 

Based on the service information, we 

estimate that this proposed AD would 

affect about 83 products of U.S. registry. 

We also estimate that it would take 

about 17 work-hour 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 $5,205 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$551,950, or $6,650 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 3 work-hours and require parts 

costing $4,643, for a cost of $4,898 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

2. The FAA amends § 39.13 by adding 

the following new AD: 

Bombardier, Inc.: Docket No. FAA–2012–

(d) Subject 

Air Transport Association (ATA) of 

America Code 32: Landing Gear. 

(e) Reason 

This AD was prompted by cases of onground hydraulic accumulator/screw cap/ 

end cap failure, resulting in high-energy 

impact damage to adjacent systems and 

structure. We are issuing this AD to prevent 

failure of the screw caps and/or end caps of 

the hydraulic and parking brake 

accumulators, which could result in damage 

to the airplane’s primary structures, with 

potential adverse effect on the airplane’s 

controllability.

For airplanes having serial numbers 4001 

through 4337 inclusive: Within 1,200 flight 

hours or 6 months after the effective date of 

this AD, whichever comes first, inspect the 

parking brake hydraulic accumulator to 

determine the part number and serial 

number. Inspect to determine the part 

number and serial number in accordance 

with the Accomplishment Instructions of
