Authority: 49 U.S.C. 106(g), 40113, 44701, 

44702, 44704. 

The Proposed Special Conditions 

Accordingly, the Federal Aviation 

Administration (FAA) proposes the 

following special conditions as part of 

the type certification basis for the 

Boeing Model 747–8 airplanes. 

In addition to the provisions of 14 

CFR part 25, the following special 

conditions are proposed: 

1. The extendable escape slide must 

receive TSO–C69c or latest TSO 

authorization published at the time of 

TSO application for the Door 1 Slide. 

2. In addition to the requirements of 

§ 25.810(a)(1)(iii) for usability in 

conditions of landing gear collapse, the 

deployed escape slide in the extended 

mode must demonstrate an evacuation 

rate of 45 persons per minute per lane 

at the sill height corresponding to 

activation of the extension. 

3. In lieu of the requirements of 

§ 25.810(a)(1)(iv), the escape slide with 

the extendable section activated must be 

capable of being deployed in 22-knot 

winds directed from the critical angle, 

with the airplane on all its landing gear, 

with the assistance of one person on the 

ground. Two deployment scenarios 

must be addressed as follows: 

(a) Extendable section is activated 

during the inflation time of the basic 

slide and, 

(b) Extendable section is activated 

after the basic slide is completely 

inflated. 

4. Pitch sensor tolerances and 

accuracy must be taken into account 

when demonstrating compliance with 

§ 25.1309(a) for the escape slide in both 

extended and unextended modes. 

5.(a) There must be a ‘‘slide extension’’ 

warning such that the cabin crew is 

immediately made aware of the need to 

deploy the extendable section of the 

slide. The ability to provide such a 

warning must be available for ten 

minutes after the airplane is 

immobilized on the ground. 

(b) There must be a positive means for 

the cabin crew to determine that the 

extendable portion of the slide has been 

fully erected. 

6. Whenever passengers are carried on 

the main deck of the airplane, there 

must be a cabin crewmember stationed 

on each side of the airplane located near 

each Door 1 Exit. This special condition 

must be included in the airplane flight 

manual as a limitation.

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

extension of the comment period. 

SUMMARY: We are revising an earlier 

NPRM 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: 

It has been found that moisture may 

accumulate and freeze, under certain 

conditions, in the gap between the AOA vane 

base assembly and the stationary ring of the 

sensor’s body. If freezing occurs both AOA 

sensors may get stuck and the Stall Warning 

Protection System (SWPS) will be no longer 

effective without alerting. This may result in 

inadvertent aerodynamic stall and loss of 

controllability of the airplane. 

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 June 24, 2011.

mstockstill on DSKH9S0YB1PROD with PROPOSALS

26960 Federal Register / Vol. 76, No. 90 / Tuesday, May 10, 2011 / Proposed Rules 

Discussion 

We proposed to amend 14 CFR part 

39 with an earlier NPRM for the 

specified products, which was 

published in the Federal Register on 

January 31, 2011 (76 FR 5298). That 

earlier NPRM proposed to require 

actions intended to address the unsafe 

condition for the products listed above. 

Since that NPRM was issued, 

EMBRAER issued new service 

information that adds actions to inspect 

the sensor area and apply sealant 

around the sensors and also adds 

additional airplanes to the applicability. 

The Ageˆncia Nacional de Aviac ̧a ̃o 

Civil—Brazil (ANAC), which is the 

aviation authority for Brazil, has issued 

Notice of Proposed Regulation (NPR) 

NPR/AD 2011–500–02, dated March 31, 

2011, to add additional information 

from the revised service information to 

correct an unsafe condition for the 

specified products. The NPR states: 

It has been found that moisture may 

accumulate and freeze, under certain 

conditions, in the gap between the AOA vane 

base assembly and the stationary ring of the 

sensor’s body. If freezing occurs both AOA 

sensors may get stuck and the Stall Warning 

Protection System (SWPS) will be no longer 

effective without alerting. This may result in 

inadvertent aerodynamic stall and loss of 

controllability of the airplane. 

Since this condition may occur in other 

airplanes of the same type and affects flight 

safety, a corrective action is required. Thus, 

sufficient reason exists to request compliance 

with this AD in the indicated time limit. 

You may obtain further information by 

examining the NPR in the AD docket. 

Relevant Service Information 

Embraer—Empresa Brasileira de 

Aeronautica S.A. has issued PHENOM 

Service Bulletin SB No.: 500–27–0006, 

Revision No.: 02, dated January 14, 

2011. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

Comments 

We have considered the following 

comments received on the earlier 

NPRM. 

Service Information Revision 

Embraer commented that new 

requirements to inspect the sensor area 

and apply sealant around the interface 

between the angle of attack (AOA) 

covers and the new AOA sensors were 

included in a revision to the service 

information referenced in the earlier 

NPRM. If the new requirements in the 

revised service information were not 

included in the proposed NPRM action, 

the new AOA sensors could be subject 

to the same behavior as the old AOA 

sensors. Embraer suggests changing the 

proposed NPRM to include the actions 

and procedures required by the new 

revised service information. 

We agree with this comment. If we do 

not incorporate the additional actions 

and procedures required by the revised 

service information, moisture could still 

accumulate and freeze, under certain 

conditions, in the gap between the new 

AOA vane base assembly and the 

stationary ring of the new sensor’s body. 

This condition could cause the sensors 

to get stuck and cause the Stall Warning 

Protection System to no longer be 

effective. We propose the use of 

PHENOM Service Bulletin SB No.: 500– 

27–0006, Revision No.: 02, dated 

January 14, 2011, which incorporates 

the actions previously proposed and 

adds additional actions and procedures 

to require inspecting the sensor area and 

applying sealant around the interface 

between the AOA covers and the AOA 

sensors. 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Certain changes described above 

expand the scope of the earlier NPRM. 

As a result, we have determined that it 

is necessary to reopen the comment 

period to provide additional 

opportunity for the public to comment 

on the proposed AD. 

Differences Between This Proposed 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. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 101 products of U.S. registry. 

We estimate that 85 products of U.S. 

registry would require the modification 

and that it would take about 9.5 workhours per product to comply with the 

modification requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Required parts 

would cost about $1,550 per product. 

Based on these figures, we estimate 

the cost of the modification requirement 

of the proposed AD on U.S. operators to 

be $200,387.50, or $2,357.50 per 

product. 

We estimate that 101 products of U.S. 

registry would require an inspection for 

sealant application. We estimate it 

would take .5 hours to comply with the 

inspection requirements of this 

proposed AD. 

Based on these figures, we estimate 

the cost of the inspection for the sealant 

application requirement of the proposed 

AD on U.S. operators to be $4,292.50, or 

$42.50 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1.5 work-hours and require parts 

costing $50, for a cost of $177.50 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 

mstockstill on DSKH9S0YB1PROD with PROPOSALS

Federal Register / Vol. 76, No. 90 / Tuesday, May 10, 2011 / Proposed Rules 26961 

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.

2. The FAA amends § 39.13 by adding 

the following new AD: 

Embraer—Empresa Brasileira de 

Aeronautica S.A.: Docket No. FAA– 

2011–0088; Directorate Identifier 2010– 

CE–072–AD. 

Comments Due Date

Aeronautica S.A. (EMBRAER) EMB–500 

airplanes, serial numbers 50000005 through 

50000217, 50000219 through 50000221, and 

50000226. 

Note 1: In-production effectivity—Empresa 

Brasileira de Aeronautica S.A. (EMBRAER) 

EMB–500 airplanes, serial numbers 

500000218, 50000222 through 50000225, 

50000227, and on, have incorporated the 

proposed actions of this AD at the factory 

and are not included in the applicability of 

this AD. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 27: Flight Controls. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

It has been found that moisture may 

accumulate and freeze, under certain 

conditions, in the gap between the AOA vane 

base assembly and the stationary ring of the 

sensor’s body. If freezing occurs both AOA 

sensors may get stuck and the Stall Warning 

Protection System (SWPS) will be no longer 

effective without alerting. This may result in 

inadvertent aerodynamic stall and loss of 

controllability of the airplane. 

Since this condition may occur in other 

airplanes of the same type and affects flight 

safety, a corrective action is required. Thus, 

sufficient reason exists to request compliance 

with this AD in the indicated time limit. 

The MCAI requires replacement of both 

Angle of Attack (AOA) sensors and cover 

plates, inspection of the sensor area, and, if 

needed, application of sealant between the 

AOA covers and the AOA sensors. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) For Group I airplanes: Within 300 hours 

time-in-service (TIS) after the effective date 

of this AD or within 12 months after the 

effective date of this AD, whichever comes 

first, do the following actions following part 

I of PHENOM Service Bulletin SB No.: 500– 

27–0006, Revision No.: 02, dated January 14, 

2011: 

(i) Replace the left hand (LH) and the right 

hand (RH) AOA sensors P/N C–100117–2 

with LH and RH AOA sensors P/N C– 

100117–3. 

(ii) Replace the LH cover plate P/N 500– 

01702–401 and the RH cover plate P/N 500– 

01702–402 with LH cover plate P/N 500– 

01702–403 and RH cover plate P/N 500– 

01702–404. 

(iii) If, before the effective date of this AD, 

the replacement actions required in 

paragraphs (f)(1)(i), and (ii) of this proposed 

AD have already been done following 

PHENOM Service Bulletin SB No.: 500–27– 

0006, dated September 2, 2010, and/or 

PHENOM Service Bulletin SB No.: 500–27– 

0006, Revision No.: 01, dated November 29, 

2010, we will allow ‘‘unless already done’’ 

credit for corrective actions already done. 

(4) For group I and group II airplanes: 

Within 300 hours TIS after the effective date 

of this AD or within 12 months after the 

effective date of this AD, whichever comes 

first, inspect the interface between the AOA 

covers and the AOA sensors, and, if the 

sealant is missing, clean the areas and apply 

new sealant following part II of PHENOM 

Service Bulletin SB No.: 500–27–0006, 

Revision No.: 02, dated January 14, 2011. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. Send information to

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above that would 

supersede an existing AD. 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: 

* * * [C]racks * * * in sections 13 to 18 of 

the fuselage between rivets of longitudinal 

lap joints between frames 18 and 80 which 

could affect the structural integrity of the 

fuselage if not corrected. 

* * * * * 

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 June 24, 2011.

Discussion 

On December 20, 1989, we issued AD 

90–01–10, Amendment 39–6448 (55 FR 

261, January 4, 1990). That AD required 

actions intended to address an unsafe 

condition on the products listed above. 

Since we issued AD 90–01–10, Airbus 

has refined the inspection program for 

cracking at areas of the fuselage defined 

in AD 90–01–10 as ‘‘special areas’’ 

(paragraph A.1. of AD 90–01–10), 

‘‘standard areas’’ (paragraph A.2. of AD 

90–01–10), and ‘‘modified or repaired 

areas’’ (paragraph A.3. of AD 90–01–10). 

The new inspection program is designed 

to allow airplanes to reach their limit of 

validity (LOV). Certain compliance 

times are reduced and certain other 

compliance times are extended. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2007–0091, 

dated April 10, 2007, and corrected June 

23, 2008 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

This Airworthiness Directive (AD) is issued 

in order to prevent cracks development in 

sections 13 to 18 of the fuselage between 

rivets of longitudinal lap joints between 

frames 18 and 80 which could affect the 

structural integrity of the fuselage if not 

corrected. 

This new AD: 

—Retains the requirements of DGAC AD 

1989–061–092(B)R4 [which corresponds to 

FAA AD 90–01–10], which is cancelled; 

—Takes into account a new inspection 

program as detailed in AIRBUS Service 

Bulletins (SB) A300–53–0211 Revision 7, 

which will allow A300 aircraft to reach the 

Limit of Validity (LOV). 

This AD has been republished to correctly 

refer to SB A300–53–0211 in Note 2 of the 

Compliance section. 

The inspection program consists of 

repetitive detailed inspections for 

disbonding and cracking of the fuselage 

inner doubler; eddy current and 

ultrasonic inspections of the fuselage 

longitudinal lap joints for cracking; and 

repair if necessary (i.e., repairing any 

cracking or disbonding, or contacting 

Airbus for repair instructions and doing 

the repair). You may obtain further 

information by examining the MCAI in 

the AD docket.
