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

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Model SAAB 2000 Airplanes. This 

proposed AD was prompted by reports 

that environmentally friendly de-icing 

agents used on certain electrical 

connectors and braids could cause 

corrosion damage. This proposed AD 

would require performing in certain 

locations a detailed inspection for 

corrosion of the electrical and 

electronics installation, and if corrosion 

is found repairing each affected harness 

braid or replacing each affected 

component and/or wiring harness. We 

are proposing this AD to detect and 

correct corrosion of critical system 

wiring, which could result in arcing 

and, in combination with other factors, 

a fire and consequent damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by April 13, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2011–0079, 

dated May 5, 2011 (referred to after this 

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

condition for the specified products. 

The MCAI states: 

Environmentally friendly de-/anti-icing 

agents (acetates or formats) are a known 

cause of corrosion damage to components of 

the Electrical Wiring Interconnection System 

(EWIS) on aeroplanes. 

Investigations by SAAB have identified 

certain electrical connectors and braids 

which are susceptible to such damage, in 

zones 191 and 192 of the center wing 

fuselage and in zones 323, 332 and 342, 

affecting the wiring harnesses of elevator and 

rudder servos. 

This condition, if not detected and 

corrected, could lead to damage of critical 

system wiring, possibly resulting in arcing 

and, in combination with other factors, a fire 

and consequent damage to, or loss of, the 

aeroplane. 

To address this unsafe condition, SAAB 

have issued Service Bulletin (SB) 2000–92– 

005 and SB 2000–92–006 to provide 

instructions to detect unacceptable corrosion 

on electrical and electronic installation 

wiring. 

For the reasons described above, this 

[EASA] AD requires a one-time [detailed] 

inspection of the affected components in the 

designated area, the reporting of all 

inspections results to SAAB and, depending 

on findings, appropriate corrective action 

[repair or replacement]. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Saab AB, Saab Aerosystems has 

issued Service Bulletins 2000–92–005, 

Revision 01, dated March 1, 2011; and 

2000–92–006, Revision 01, dated 

August 18, 2010. 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 10 products of U.S. registry. 

We also estimate that it would take 

about 360 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$306,000, or $30,600 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 40 work-hours and require parts 

costing $12,454, for a cost of $15,854 

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.

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus Model A300 B4–103, B4–203, 

and B4–2C airplanes, and Model B4– 

600, B4–600R, and F4–600R series 

airplanes, and Model C4–605R Variant F 

airplanes (collectively called A300–600 

series airplanes). This proposed AD was 

prompted by reports of cracking in the 

forward lug of the main landing gear 

(MLG) rib 5 aft bearing attachment. This 

proposed AD would require repetitive 

inspections for cracking of the left-hand 

(LH) and right-hand (RH) wing MLG rib 

5 aft bearing forward lugs and repair if 

necessary. We are proposing this AD to 

detect and correct cracking of the LH 

and RH wing MLG rib 5 aft bearing 

forward lugs which, if not corrected,
