Airworthiness Directives; BAE 

SYSTEMS (OPERATIONS) LIMITED

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 Avro 146– 

RJ airplanes. This proposed AD was 

prompted by a report of a crack found 

on the left-hand sidewall well on the 

nose landing gear (NLG). This proposed 

AD would require performing a 

repetitive high frequency eddy current 

inspection of the stiffeners on the lefthand sidewall on the NLG gear bay for 

cracks, and repair or replace the 

sidewall if necessary. Replacing the 

sidewall with a certain sidewall part 

number constitutes a terminating action 

for the repetitive inspections. We are 

proposing this AD to detect and correct 

failure of the sidewall, which could 

result in consequent in-flight rapid 

decompression of the cabin and injury 

to the passengers. 

DATES: We must receive comments on 

this proposed AD by April 20, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the

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 2011–0097, 

dated May 25, 2011 (referred to after 

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

condition for the specified products. 

The MCAI states: 

During accomplishment of EASA AD 

2007–0305 on an Avro 146–RJ85, a corner 

crack was found on the left hand Nose 

Landing Gear (NLG) sidewall well. The crack 

was located on one of the sidewall stiffeners 

adjacent to the area being inspected. In this 

instance, the cracking was severe enough to 

warrant replacement of the sidewall. 

Analysis has shown that these types of cracks 

are likely to exist or develop in other 

aeroplanes of the same design. 

This condition, if not detected and 

corrected, could result in failure of the 

sidewall and consequent in-flight rapid 

decompression of the cabin and injury to its 

occupants. 

For the reasons described above, this 

[EASA] AD requires repetitive [high 

frequency eddy current] inspections of the 

stiffeners [for cracks] on the left hand NLG 

sidewall. This [EASA] AD also introduces an 

optional terminating action for the repetitive 

inspections. 

The corrective actions include 

repairing or replacing the sidewall with 

a new sidewall. 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.53–229, Revision 1, dated 

November 22, 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. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

This proposed AD specifies not 

installing certain sidewalls after the 

installation of a new sidewall is done. 

This proposed AD does not allow 

installation of certain sidewalls as of the 

effective date of this proposed AD. 

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 2 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 

$170. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 2 work-hours and require parts 

costing $8,850, for a cost of $9,020 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.

and detect failure of the sidewall, which 

could result in consequent in-flight rapid 

decompression of the cabin and injury to the

the inspection thereafter at intervals not to 

exceed 12,000 flight cycles, except as 

provided in paragraph (i) of this AD. 

(h) Repair 

If, during any inspection required by 

paragraph (g) of this AD, any crack is found 

in the sidewall stiffeners, before further flight 

repair the sidewall stiffeners, using a method 

approved by either the Manager, 

International Branch, ANM 116, Transport 

Airplane Directorate, FAA; or the EASA (or 

its delegated agent); or do the replacement 

specified in paragraph (i) of this AD. 

(i) Optional Replacement 

Replacement of the sidewall stiffeners, 

with sidewall P/N HC537L0002–006, on any 

airplane, in accordance with the 

Accomplishment Instructions of BAE 

SYSTEMS (OPERATIONS) LIMITED 

Inspection Service Bulletin ISB.53–229,

P/N HC537L0002–000, –002, or –004, 

HC537H8021–000, –002, or –004, or 

HC537H8018–000, on any airplane. 

(k) Credit for Previous Actions 

This paragraph provides credit for 

inspections and replacements, as specified in 

paragraphs (g) and (i) of this AD, if those 

actions were performed before the effective 

date of this AD using BAE SYSTEMS 

(OPERATIONS) LIMITED Inspection Service 

Bulletin ISB.53–229, dated July 8, 2010. 

(l) Other FAA AD Provisions 

The following provisions also apply to this 

AD:

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the International Branch, send it to ATTN: 

Todd Thompson, Aerospace Engineer,

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective
