Airworthiness Directives; Airbus

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 A330–243, –243F, –341, 

–342, and –343 airplanes equipped with 

Rolls-Royce Trent 700 engines. This 

proposed AD was prompted by reports 

of extensive damage to engine air intake 

cowls as a result of acoustic panel 

collapse. This proposed AD would 

require repetitive inspections of the 

three inner acoustic panels of both 

engine air intake cowls to detect 

disbonding, and corrective actions if 

necessary. We are proposing this AD to 

detect and correct disbonding, which 

could result in detachment of the engine 

air intake cowl from the engine leading 

to ingestion of parts, which could cause 

failure of the engine, and consequent 

reduced controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 6, 2012. 

ADDRESSES: You may send comments by 

any of the following methods:

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 2011–0173, 

dated September 13, 2011 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

Two operators of A330 aeroplanes fitted 

with Rolls-Royce Trent 700 engines reported 

finding extensive damage to engine air intake 

cowls as a result of acoustic panel collapse, 

most probably caused by panel disbonding. 

This condition, if not detected and 

corrected, could lead to the detachment of 

the engine air intake cowl from the engine, 

possibly resulting in ingestion of parts by, 

and consequence damage to, the engine, or 

injury to persons on the ground. 

For the reasons described above, this 

[EASA] AD requires repetitive special 

detailed inspections (tap tests) of the 3 inner 

acoustic panels of both engine air intake 

cowls to detect any disbonding and, 

depending on findings, applicable corrective 

actions. 

The unsafe condition is detachment of 

the engine air intake cowl from the 

engine, which could result in ingestion 

of parts causing failure of the engine, 

and consequent reduced controllability 

of the airplane. Corrective actions 

include repair or replacement of the 

affected engine air intake cowl. The 

compliance time for replacing an engine 

air intake cowl that is damaged beyond 

certain damage limits is before further 

flight. For damage that is below certain 

specified damage limits, the compliance 

time for repetitive inspections is 

between 10 flight cycles and 267 flight 

cycles, or the affected unit is specified 

to be repaired before further flight. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A330–71–3024, Revision 01, 

dated September 27, 2011. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

Rolls-Royce plc has issued Alert 

Service Bulletin RB. 211–71–AG419, 

including Appendix 1, dated May 10, 

2011. 

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 22 products of U.S. registry. 

We also estimate that it would take 

about 20 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 

$37,400, or $1,700 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

up to 34 work-hours for a cost of up to 

$2,890 per product. We have received 

no definitive data that would enable us 

to provide parts cost estimates for the 

on-condition actions specified in this 

proposed AD. 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.
