Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. The existing 

AD currently requires a one-time 

inspection of the shafts of the main 

landing gear (MLG) side-brace fittings to 

detect corrosion, and the forward and 

aft bushings in the left-hand and righthand MLG side-brace fittings to detect 

discrepancies. The existing AD also 

requires corrective and related actions if 

necessary. Since we issued that AD, we 

have received reports that the side brace 

fitting shafts of the MLG continue to 

fail. This proposed AD would require 

repetitive detailed inspections for 

corrosion and damage of the MLG sidebrace fitting and replacing the sidebrace fitting shaft with the re-designed 

side-brace fitting shaft of the MLG if 

necessary. This AD would also require 

eventual replacement of certain sidebrace fitting shafts with the re-designed 

part. Replacement with a re-designed 

side-brace fitting shaft of the MLG is 

terminating action for the repetitive 

inspections. We are proposing this AD 

to prevent fractures of the side-brace 

fitting shafts of the MLG, and possible 

collapse of the MLG. 

DATES: We must receive comments on 

this proposed AD by July 27, 2012.

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On October 20, 2004, we issued AD 

2004–22–23, Amendment 39–13851 (69 

FR 64856, November 9, 2004). That AD 

required actions intended to address an 

unsafe condition on Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. 

Since we issued AD 2004–22–23, 

Amendment 39–13851 (69 FR 64856, 

November 9, 2004), we received reports 

that the side-brace fitting shaft of the 

MLG continued to fail which meant the 

existing AD did not adequately address 

the unsafe condition. Transport Canada 

Civil Aviation (TCCA), which is the 

aviation authority for Canada, has 

issued Canadian Airworthiness 

Directive CF–2011–39, dated October 

25, 2011 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Due to the failure of the main landing gear 

(MLG) side brace fitting shaft, caused by 

corrosion, [TCCA] Airworthiness Directive 

(AD) CF–2002–41 was issued to require 

inspection and if needed, parts replacement. 

However, the existing MLG side-brace fitting 

shafts continued to fail. Failure of the MLG 

side brace fitting shaft could result in the 

collapse of the main landing gear. 

This [TCCA] directive mandates the 

repetitive detailed visual inspection [for 

cracking and corrosion] of the MLG side 

brace fitting and the incorporation of the redesigned MLG side brace fitting shaft part 

number (P/N) 605R10247–3 as the 

terminating action. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 601R–57–052, dated July 28, 

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 584 products of U.S. 

registry. We estimate that it would take 

about 10 work-hours per product to 

comply with the new basic 

requirements of this proposed AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $0 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 

$496,400, or $850 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 14 work-hours and require parts 

costing $3,860, for a cost of $5,050 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.

Airworthiness Directives; Fokker 

Services B.V. 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 

Fokker Services B.V. Model F.28 Mark 

0070 and 0100 airplanes. This proposed 

AD was prompted by reports of burned 

contacts in a certain production break 

plug and its corresponding receptacle. 

This proposed AD would require 

modifying galley power supply wiring 

by disconnecting it from the affected 

plug/receptacle and reconnecting the 

power supply wiring through splices. 

We are proposing this AD to prevent a 

high electrical load which may lead to 

overheating of the galley power supply 

wiring and/or the electrical connector 

and consequent smoke or fire in the 

galley area, which could result in 

damage to the airplane and injury to 

occupants. 

DATES: We must receive comments on 

this proposed AD by July 27, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to
