Airworthiness Directives; Airbus 

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 

Airbus Model A300 series airplanes; 

Model A300 B4–600, B4–600R, and F4– 

600R series airplanes, and Model A300 

C4–605R Variant F airplanes 

(collectively called Model A300–600 

series airplanes). This proposed AD was 

prompted by a report that cracking was 

found in area 2 of the frame base fittings 

between frame 41 and frame 46. This 

proposed AD would require a check of 

maintenance records to determine if 

certain repairs were done in area 1 of 

the frame brace fittings, and, for affected 

airplanes, a detailed inspection for 

cracking in area 2 of the frame base 

fittings between frame 41 and frame 46, 

and repair if necessary. We are 

proposing this AD to detect and correct 

cracking in area 2 of the frame base 

fittings between frame 41 and frame 46, 

which could adversely affect the 

structural integrity of the airplane. 

DATES: We must receive comments on 

this proposed AD by June 28, 2013.

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 2012–0229, 

dated October 31, 2012 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

During accomplishment of Airbus SB 

[service bulletin] A300–53–6111, which 

addresses detailed visual inspections of the 

lower frame fittings between Frame (FR) 41 

and FR 46, on one A300–600 aeroplane a 

crack was detected in the area 2 of the foot 

of frame FR 46 at junction radius level. 

This frame, that was previously repaired 

due to a crack finding in the area 1, was not 

due to be inspected before reaching the postrepair inspection threshold, i.e., 45,400 FC 

[flight cycles], from repair embodiment. 

It has been determined that the current 

repairs proposed in Airbus SB A300–53– 

6111 and Airbus [SB] A300–53–0337 are of 

limited effect to prevent cracking in the area 

2 of the lower frame fittings. 

Consequently, as a temporary action and 

until an improvement of the existing repairs 

is made available, this [EASA] AD requires 

a one-time detailed visual inspection [for 

cracking] of [the] frame base fittings that were 

repaired in accordance with Airbus SB 

A300–53–0337, original issue or Rev. 1, or 

Airbus SB A300–53–6111 original issue up to 

Rev. 4 * * *. 

The unsafe condition is cracking in 

the frame base fittings, which could 

adversely affect the structural integrity 

of the airplane. The required actions 

include repairing any cracking found. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Alert Operators 

Transmission (AOT) A53W001–12, 

dated July 4, 2012, including 

Appendices 1, 2, and 3. 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. 

Differences Between This Proposed AD 

and the MCAI 

Although EASA AD 2012–0229, dated 

October 31, 2012, specifies to contact 

the manufacturer for instructions to 

repair certain conditions, this proposed 

AD would require repairing those 

conditions using a method approved by 

either the Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA; or EASA (or its 

delegated agent). 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 124 products 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. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$42,160, or $340 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

up to 350 work-hours and require parts 

costing up to $56,469 for a cost of 

$86,219 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 supersede an 

existing airworthiness directive (AD) 

that applies to all Rolls-Royce plc (RR) 

model RB211 Trent 553–61, 553A2–61, 

556–61, 556A2–61, 556B–61, 556B2–61,

–524G3–T–19, –524H–T–36, and 

–524H2–T–19 turbofan engines that 

have a high-pressure (HP) compressor 

stage 1 to 4 rotor disc installed, with a 

certain part number (P/N) installed. The 

existing AD requires repetitive 

inspections of the axial dovetail slots, 

and follow-on corrective action 

depending on findings. This proposed 

AD expands the population of affected 

parts. This proposed AD also changes, 

for the purposes of this AD, the 

definition of ‘‘engine shop visit.’’ We are 

proposing this AD to detect cracks in 

the HP compressor stage 1 and 2 disc 

posts, which could result in failure of 

the disc post and HP compressor blades, 

damage to the engine, and damage to the 

airplane.
