Airworthiness Directives; BAE

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

BAE SYSTEMS (OPERATIONS) 

LIMITED Model BAe 146 and Model 

Avro 146–RJ airplanes. This proposed 

AD was prompted by reports of cracking 

and surface anomalies of the fuselage 

skin at the water trap/air drier unit of 

the forward discharge valve due to 

corrosion. This proposed AD would 

require repetitive detailed inspections 

for bulging, surface anomalies, and 

cracking of the fuselage skin adjacent to 

the discharge valves, repair if necessary, 

and application of additional sealant in 

the affected area if necessary. We are 

proposing this AD to detect and correct 

bulging, surface anomalies, and cracking 

that could propagate towards the 

forward discharge valve outlet and 

result in the failure of the fuselage skin, 

leading to a possible sudden loss of 

cabin pressure. 

DATES: We must receive comments on 

this proposed AD by May 21, 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 2011–0099, 

dated May 26, 2011 (referred to after 

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

condition for the specified products. 

The MCAI states: 

An operator has reported the cracking and 

surface anomalies (bulges and/or dents) of 

the fuselage skin at the water trap/air drier 

unit of the forward discharge valve located 

between Frames 22 and 23 and between 

stringers 22 and 23. 

Further investigation established that these 

surface anomalies (bulges and/or dents) were 

due to corrosion beneath the water trap/air 

drier unit that has resulted in cracking of the 

fuselage skin. A crack at the subject location 

could propagate towards the forward 

discharge valve outlet and result in the 

failure of the fuselage skin leading to a 

possible sudden loss of cabin pressure. 

For the reasons described above, this 

[EASA] AD mandates an initial and repetitive 

[detailed] inspections [for bulging, surface 

anomalies, and cracking] of the fuselage skin 

adjacent to the front and rear discharge 

valves, the accomplishment of the associated 

correctives actions [repair] if applicable and 

the application of an additional sealant in the 

affected area. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

BAE SYSTEMS (OPERATIONS) 

LIMITED has issued Inspection Service 

Bulletin ISB.21–162, Revision 1, dated 

September 16, 2010; Subject 53–00–00, 

‘‘Fuselage, General Description,’’ of 

Chapter 53, ‘‘Fuselage,’’ of the BAE 

SYSTEMS BAe 146 Series/AVRO 146– 

RJ Series Structural Repair Manual for 

Series 100–200, Revision 66, dated 

October 15, 2011; and Subject 53–00–

rmajette on DSK2TPTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 66 / Thursday, April 5, 2012 / Proposed Rules 20573 

15, 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 1 product of U.S. registry. 

We also estimate that it would take 

about 8 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 

$680, or $680 per product. We have 

received no definitive data that would 

enable us to provide cost estimates for 

the on-condition (repair) actions 

specified in this proposed AD. 

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 that this AD: 

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.
