62658 Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

In 2003, a number of reports had been 

received concerning broken wires and 

corroded connectors in the SAAB 340 main 

landing gear (MLG) emergency release 

system. The investigation results showed that 

these were due to improper repairs and 

installations, not conforming to the approved 

type design. 

This condition, if not corrected, could 

inhibit the functioning of the separation bolt, 

preventing proper release of the MLG during 

an emergency situation, possibly resulting in 

damage to aeroplane during landing and 

injury to the occupants. 

* * * * *

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

As required by current certification 

standards, each transport aeroplane has 

passenger compartment exit signs and 

emergency lighting strips installed to locate 

the emergency exits. A number of these strips 


srobinson on DSK4SPTVN1PROD with PROPOSALS

and signs are not electrically powered, but 

are self illuminated by means of a hydrogen 

isotope, known as Tritium. As this isotope 

decays over time, these signs will [lose] their 

brightness. 

To remain compliant with regulations, 

Tritium exit signs and lighting strips should 

be replaced when their brightness has 

deteriorated below accepted levels. 

Currently, the Maintenance Review Board 

(MRB) Maintenance Planning Document does 

not include an inspection task for signs and 

strips containing Tritium. 

This condition, if not detected and 

corrected, could result in insufficiently bright 

exit signs and lighting strips, preventing safe 

evacuation during an emergency, possibly 

resulting in injury to occupants. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by November 25, 

2011. 

ADDRESSES: You may send comments by

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 2010–0261, 

dated December 9, 2010 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

As required by current certification 

standards, each transport aeroplane has 

passenger compartment exit signs and 

emergency lighting strips installed to locate 

the emergency exits. A number of these strips 

and signs are not electrically powered, but 

are self illuminated by means of a hydrogen 

isotope, known as Tritium. As this isotope 

decays over time, these signs will [lose] their 

brightness. 

To remain compliant with regulations, 

Tritium exit signs and lighting strips should 

be replaced when their brightness has 

deteriorated below accepted levels. 

Currently, the Maintenance Review Board 

(MRB) Maintenance Planning Document does 

not include an inspection task for signs and 

strips containing Tritium. 

This condition, if not detected and 

corrected, could result in insufficiently bright 

exit signs and lighting strips, preventing safe 

evacuation during an emergency, possibly 

resulting in injury to occupants. 

To correct this unsafe condition, EASA 

issued AD 2010–0200, which required [a 

detailed visual] inspection of the brightness 

of all Tritium exit signs and strips and, 

depending on findings, replacement of 

insufficiently bright signs and lighting strips. 

Following the issuance of [EASA] AD 

2010–0200, Fokker Services discovered that 

one Service Bulletin (SB), SBF100–33–023, 

contained errors in the two groups of 

aeroplane serial numbers and, consequently, 

in the related instructions for those 

aeroplanes in that SB. 

For the reasons described above, this new 

[EASA] AD retains the requirements of EASA 

AD 2010–0200, which is superseded, amends 

the Applicability and refers to Revision 1 of 

SBF100–33–023 for the accomplishment 

instructions. 

Note: The MRB document will be updated 

before July 2011 to include an appropriate 

maintenance task to ensure that the Tritium 

exit signs and lighting strips meet the 

minimum brightness requirements. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Fokker Services B.V. has issued 

Service Bulletins SBF50–33–038, dated 

July 5, 2010; and SBF100–33–023, 

Revision 1, dated November 4, 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 AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD.

62660 Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 4 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour 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 

$340, or $85 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 2 work-hours and require parts 

costing $833, for a cost of $1,003 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); and 

3. 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.

Subject 

(d) Air Transport Association (ATA) of 

America Code 33: Lights. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

As required by current certification 

standards, each transport aeroplane has 

passenger compartment exit signs and 

emergency lighting strips installed to locate 

the emergency exits. A number of these strips 

and signs are not electrically powered, but 

are self illuminated by means of a hydrogen 

isotope, known as Tritium. As this isotope 

decays over time, these signs will [lose] their 

brightness. 

To remain compliant with regulations, 

Tritium exit signs and lighting strips should 

be replaced when their brightness has 

deteriorated below accepted levels. 

Currently, the Maintenance Review Board 

(MRB) Maintenance Planning Document does 

not include an inspection task for signs and 

strips containing Tritium. 

This condition, if not detected and 

corrected, could result in insufficiently bright 

exit signs and lighting strips, preventing safe 

evacuation during an emergency, possibly 

resulting in injury to occupants. 

* * * * * 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Within six months after the effective 

date of this AD, do a detailed visual 

inspection of the tritium exit signs and 

emergency lighting strips for required 

brightness, in accordance with the 

Accomplishment Instructions of Fokker 

Service Bulletin SBF50–33–038, dated July 5, 

2010; or SBF100–33–023, Revision 1, dated 

November 4, 2010; as applicable. If any exit 

signs or emergency lighting strips are 

insufficiently bright, before further flight, 

replace the exit signs or emergency lighting 

strips, in accordance with the 


srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules 62661 

Accomplishment Instructions of Fokker 

Service Bulletin SBF50–33–038, dated July 5, 

2010; or SBF100–33–023, Revision 1, dated 

November 4, 2010; as applicable. A review of 

airplane maintenance records is acceptable in 

lieu of the inspection in this paragraph if the 

tritium exit signs and emergency lighting 

strips can be conclusively determined to 

have been manufactured in 2003 or earlier, 

from that review; however, the replacement 

in this paragraph must be accomplished 

before further flight after doing the review. 

Parts Installation 

(h) As of the effective date of this AD, no 

person may install any tritium exit signs or 

emergency lighting strips if the 

manufacturing date is seven years or more 

before the intended installation date, or if the 

manufacturing date cannot be determined; 

unless the tritium exit sign or emergency 

lighting strip has been inspected in 

accordance with paragraph (g) of this AD, 

and does not need replacement.

Airworthiness Directives; The Boeing 

Company Model 767–200 and –300 

Series 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 

Model 767–200 and 767–300 series 

airplanes. This proposed AD would 

require installing cargo bulkhead 

supports, ceiling supports, secondary 

dam support, drainage tubing, and 

ceiling panels to the forward lower lobe 

in the forward cargo compartment. This 

proposed AD was prompted by reports 

of water accumulation in the forward 

lower lobe of the forward cargo 

compartment. We are proposing this AD 

to prevent water from accumulating in 

the forward lower lobe of the forward 

cargo compartment and entering the 

adjacent electronic equipment bay, 

which could result in an electrical short 

and the potential loss of several 

functions essential for safe flight. 

DATES: We must receive comments on 

this proposed AD by November 25, 

2011. 

ADDRESSES: You may send comments by 

any of the following methods:
