AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all BAE 

Systems (Operations) Limited Model 

BAe 146 and Avro 146–RJ series 

airplanes. This proposed AD was 

prompted by a report of a cracked pickup bracket of the forward outboard 

pylon of the number 1 engine due to 

stress corrosion. This proposed AD 

would require repetitive inspections 

and, depending on findings, repair of 

the pylon pick-up brackets. We are 

proposing this AD to detect and correct 

cracking of the pick-up bracket, which 

could result in the engine pylon 

separating from the wing, with 

consequent damage to the airplane and 

reduced controllability. 

DATES: We must receive comments on 

this proposed AD by September 16, 

2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

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

instructions for submitting comments.

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 2012–0136, 

dated July 20, 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: 

While carrying out a scheduled 

environmental inspection, an operator found 


ehiers on DSK2VPTVN1PROD with PROPOSALS-1
46302 Federal Register / Vol. 78, No. 147 / Wednesday, July 31, 2013 / Proposed Rules 

a cracked number 1 engine forward outboard 

pylon pick-up bracket. Cracks were present 

on the upper flange of the bracket running 

between all 3 attachment bolt holes. 

Subsequent investigation revealed that the 

cause of cracking was stress corrosion. 

Cracking of the pylon pick-up brackets at the 

top and bottom flanges could reduce the 

capability of the brackets to support the 

ultimate sideload, particularly if cracking is 

present on more than one flange. 

This condition, if not detected and 

corrected, could result in the engine pylon 

separation from the wing, likely resulting in 

damage to [and controllability of] the 

aeroplane and possible injury to persons on 

the ground. 

* * * * * 

For reasons described above, this AD 

requires the inspection and, depending on 

findings, repair of the affected pylon pick-up 

brackets. 

The inspection includes a special 

detailed inspection with a videoscope. 

Corrective actions can include replacing 

any affected pylon pick-up brackets, and 

doing any follow-on skin repairs. 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.57–073, Revision 1, dated January 

27, 2012; and Revision 2, dated March 

8, 2012. 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 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, or $170 per product. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition 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 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.

Airworthiness Directives; Fokker 

Services B.V. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Fokker Services B.V. Model F.28 Mark 

0070 and 0100 airplanes. This proposed 

AD was prompted by a design review, 

which revealed that, under certain 

failure conditions, wiring in the main 

fuel tank could develop a short circuit 

that might cause a hot spot on the 

wiring conduit or puncture the wiring 

conduit wall. This proposed AD would 

require installing fuses in the power 

supply wiring and/or return wiring for 

various components in the fuel system; 

and revising the airplane maintenance 

program by incorporating critical design 

configuration control limitations. We 

are proposing this AD to prevent an 

ignition source in the main fuel tank 

vapor space, which could result in a 

fuel tank explosion and consequent loss 

of the airplane. 

DATES: We must receive comments on 

this proposed AD by September 16, 

2013. 

ADDRESSES: You may send comments by 

any of the following methods:
