52948 Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2015–18–01 Vulcanair S.p.A.: Amendment 

39–18259; Docket No. FAA–2015–3656; 

Directorate Identifier 2015–CE–027–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective September 22, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Vulcanair S.p.A. 

Models P.68R airplanes, serial numbers 458/ 

R and subsequent, certificated in any 

category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 34: Navigation. 

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

issued by the aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as a 

discrepancy in the climb performance 

reported in the airplane flight manual (AFM) 

and/or pilots operating handbook (POH) in 

the actual performance of the airplane. We 

are issuing this AD to correct the AFM by 

inserting the proper climb performance data 

into the manual, which if not corrected could 

result in over-estimation of the airplane’s rate 

of climb, resulting in impact with 

obstructions or terrain. 

(f) Actions and Compliance 

Unless already done, within 30 days after 

the effective date of this AD, insert pages 5– 

1 through 5–34, into Section 5, Revision 27, 

dated April 23, 2015, of the Vulcanair 

Aircraft P.68R POH/AFM, NOR10.707–30C, 

Revision 17, dated July 22, 2013; and pages 

1 through 42, into Supplement F, in Section 

8, Revision 27; dated April 23, 2015, of the 

Vulcanair Aircraft P.68R POH/AFM,

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777–200 

and –300 series airplanes equipped with 

Pratt and Whitney engines. This AD was 

prompted by reports of blocked drain 

lines at the engine forward strut that 

caused flammable fluid to accumulate 

in a flammable leakage zone. This AD 

requires repetitive functional checks for 

blockage of the forward strut drain line 

and doing corrective actions if 

necessary, and a one-time cleaning of 

certain forward strut drain lines. This 

AD also provides an optional 

replacement of the drain lines and 

installation of insulation blankets, and a 

revision of the maintenance or 

inspection program, as applicable, to 

incorporate a certain airworthiness 

limitation, which would terminate the 

repetitive checks of the forward strut 

drain line. We are issuing this AD to 

detect and correct blockage of forward 

strut drain lines, which could cause 

flammable fluids to collect in the 


asabaliauskas on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations 52949 

forward strut area and potentially cause 

an uncontrolled fire or cause failure of 

engine attachment structure and 

consequent airplane loss. 

DATES: This AD is effective October 7, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 7, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 777–200 and –300 series 

airplanes equipped with Pratt and 

Whitney engines. The NPRM published 

in the Federal Register on August 7, 

2014 (79 FR 46201). The NPRM was 

prompted by reports of blocked drain 

lines at the engine forward strut that 

caused flammable fluid to accumulate 

in a flammable leakage zone. The NPRM 

proposed to require repetitive functional 

checks for blockage of the forward strut 

drain line and doing corrective actions 

(including cleaning or replacing any 

blocked drain lines) if necessary, and a 

one-time cleaning of certain forward 

strut drain lines. We are issuing this AD 

to detect and correct blockage of 

forward strut drain lines, which could 

cause flammable fluids to collect in the 

forward strut area and potentially cause 

an uncontrolled fire or cause failure of 

engine attachment structure and 

consequent airplane loss. 

This AD requires revisions to certain 

operator maintenance documents to 

include new actions (e.g., inspections). 

Compliance with these actions is 

required by 14 CFR 91.403(c). For 

airplanes that have been previously 

modified, altered, or repaired in the 

areas addressed by this AD, the operator 

may not be able to accomplish the 

actions described in the revisions. In 

this situation, to comply with 14 CFR 

91.403(c), the operator must request 

approval for an alternative method of 

compliance according to paragraph (l) of 

this AD. The request should include a 

description of changes to the required 

inspections that will ensure the 

continued operational safety of the 

airplane. 

Related Rulemaking 

On September 23, 2014, we issued AD 

2014–20–10, Amendment 39–17983 (79 

FR 60331, October 7, 2014), for certain 

The Boeing Company Model 777–200 

and –300 series airplanes. AD 2014–20– 

10 superseded AD 2013–11–14, 

Amendment 39–17474 (78 FR 35749, 

June 14, 2013). AD 2014–20–10 

currently requires repetitive general 

visual inspections of the strut forward 

dry bay for the presence of hydraulic 

fluid, and related investigative and 

corrective actions (including checking 

drain lines for blockage due to hydraulic 

fluid coking; cleaning or replacing drain 

lines to allow drainage) if necessary; 

and adds airplanes to the applicability. 

AD 2014–20–10 was prompted by 

reports of hydraulic fluid contamination 

(including contamination caused by 

hydraulic fluid in its liquid, vapor, and/ 

or solid (coked) form) found in the strut 

forward dry bay. The actions required 

by 2014–20–10 are intended to detect 

and correct hydraulic fluid 

contamination of the strut forward dry 

bay, which could result in hydrogen 

embrittlement of the titanium forward 

engine mount bulkhead fittings, and 

consequent inability of the fittings to 

carry engine loads and resulting in 

engine separation. Hydrogen 

embrittlement also could cause a 

through-crack formation across the 

fittings through which an engine fire 

could breach into the strut, resulting in 

an uncontained strut fire. 

On December 22, 2014, we issued AD 

2015–01–01, Amendment 39–18062 (80 

FR 3158, January 22, 2015) for certain 

The Boeing Company Model 777–200 

and –300 series airplanes. AD 2015–01– 

01 superseded AD 2011–09–11, 

Amendment 39–16673 (76 FR 24354, 

May 2, 2011). AD 2015–01–01 currently 

requires repetitive inspections for 

hydraulic fluid contamination of the 

interior of the strut disconnect 

assembly; repetitive inspections for 

discrepancies of the interior of the strut 

disconnect assembly, if necessary; 

repetitive inspections of the exterior of 

the strut disconnect assembly for cracks, 

if necessary; and corrective action if 

necessary. AD 2015–01–01 also 

provides an optional terminating action 

for the inspections and adds, for certain 

airplanes, an inspection of the side and 

top cover plates to determine if all cover 

plate attach fasteners have been 

installed, installing any missing 

fasteners including doing an inspection 

for damage, and repair if necessary. 

AD 2015–01–01, Amendment 39– 

18062 (80 FR 3158, January 22, 2015) 

was prompted by reports of side and top 

cover plates installed with missing 

fastener bolts, which could result in an 

unsealed opening on the system 

disconnect assembly. The actions 

required by AD 2015–01–01 are 

intended to detect and correct hydraulic 

fluid contamination, which could cause 

cracking of titanium parts in the system 

disconnect assembly. The actions of 

2015–01–01 are also intended to detect 

and correct missing fasteners, which 

could result in unsealed openings on 

the system disconnect assembly. Both 

unsafe conditions can compromise the 

engine firewall and result in fire hazards 

for both the engine compartment and 

the strut. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM (79 FR 46201, 

August 7, 2014) and the FAA’s response 

to each comment. 

Request To Add Service Information as 

Optional Terminating Action 

Boeing and Japan Airlines (JAL) 

requested that we add Boeing Special 

Attention Service Bulletin 777–71– 

0055, dated June 12, 2014, as a 

terminating action to the NPRM (79 FR 


asabaliauskas on DSK5VPTVN1PROD with RULES
52950 Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations 

46201, August 7, 2014). Boeing 

specifically requested that this service 

information be added in the 

Supplementary Information—Interim 

Action section and as a second 

paragraph to paragraph (i) of the NPRM. 

Boeing requested that paragraph (i) of 

the NPRM state that accomplishment of 

Boeing Special Attention Service 

Bulletin 777–71–0055, dated June 12, 

2014, terminates the requirements of 

Boeing Special Attention Service 

Bulletin 777–54–0027, Revision 1, dated 

September 12, 2013, and is an 

alternative means of compliance with 

this AD. 

We agree. Boeing Special Attention 

Service Bulletin 777–71–0055, dated 

June 12, 2014, which has since been 

revised as Revision 1, dated April 15, 

2015, describes procedures that address 

the identified unsafe condition. These 

procedures include removing the 

forward strut drain lines; cleaning the 

left systems disconnect, strut forward 

lower spar, and forward fireseal pan 

drain lines; installing new forward strut 

drain lines and insulation blankets; and 

doing a functional leak check of the 

forward strut drain lines, and repair if 

any leaking is found. 

We have added new paragraph (i) to 

this AD to provide optional terminating 

action and redesignated subsequent 

paragraphs accordingly. Paragraph (i) of 

this AD states that accomplishment of 

Boeing Special Attention Service 

Bulletin 777–71–0055, Revision 1, dated 

April 15, 2015, along with a revision of 

the maintenance or inspection program, 

as applicable, to incorporate a certain 

airworthiness limitation, terminates the 

requirements of paragraph (g)(1) of this 

AD at the modified area only. 

We have also added new paragraph (j) 

of this AD to specify that no alternative 

actions or intervals may be used after 

incorporating the airworthiness 

limitation unless the actions or intervals 

are approved as an alternative method 

of compliance (AMOC) in accordance 

with the procedures specified in 

paragraph (l) of this AD. We 

redesignated subsequent paragraphs 

accordingly. 

We have also added new paragraph 

(k) to this AD to give credit for actions 

required by paragraph (i) of this AD, if 

those actions were performed before the 

effective date of this AD using Boeing 

Special Attention Service Bulletin 777– 

71–0055, dated June 12, 2014. We 

redesignated subsequent paragraphs 

accordingly. 

In addition, we updated the ‘‘Interim 

Action’’ paragraph in the 

SUPPLEMENTARY INFORMATION section of 

the preamble of this final rule 

accordingly. 

Request To Remove Requirement To 

Clean Forward Strut Drain Line 

All Nippon Airways (ANA) requested 

that we revise the NPRM (79 FR 46201, 

August 7, 2014) to remove the phrase 

‘‘clean the forward strut drain line’’ 

from paragraph (g)(1) of the NPRM. 

ANA stated that cleaning the forward 

strut drain line is not required if part 1, 

condition 1, in paragraph 3.B ‘‘Work 

Instructions,’’ of Boeing Special 

Attention Service Bulletin 777–54– 

0027, Revision 1, dated September 12, 

2013, is met. 

We agree because condition 1 is met 

when 354 or more ounces of water are 

collected within 2 minutes after the start 

of pouring water for the functional 

check of the forward strut drain line. 

Cleaning the blocked drain line is part 

of the corrective actions in condition 2 

as specified in Boeing Special Attention 

Service Bulletin 777–54–0027, Revision 

1, dated September 12, 2013. This 

change does not compromise safety or 

the intent of the AD, therefore, we have 

removed the phrase ‘‘clean the forward 

strut drain line,’’ from paragraph (g)(1) 

of this final rule. 

Request To Allow Alternate Tee Fitting 

Part Numbers 

ANA requested the NPRM (79 FR 

46201, August 7, 2014) include three 

part numbers of the tee fitting. ANA 

indicated that paragraph 2.C., of Boeing 

Special Attention Service Bulletin 777– 

54–0027, Revision 1, dated September 

12, 2013, states BACT16BR120612J tee 

fitting is required if replacement is 

necessary. ANA stated tee fittings 

having part numbers 

BACT16BR120612J, 

BACT16BR120612JN, and 

AS4139J120612 may be used according 

to a Boeing product standard parts list. 

We agree because the tee fitting part 

number BACT16BR120612J listed in 

Boeing Special Attention Service 

Bulletin 777–54–0027, Revision 1, dated 

September 12, 2013, is obsolete. We 

have added text to paragraph (g)(1) of 

this AD to allow alternate tee fitting part 

numbers BACT16BR120612JN and 

AS4139J120612, as long as the 

installation of the forward strut drain 

lines is accomplished in accordance 

with the Accomplishment Instructions 

of Boeing Special Attention Service 

Bulletin 777–54–0027, Revision 1, dated 

September 12, 2013. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

46201, August 7, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 46201, 

August 7, 2014). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Interim Action 

We consider this AD interim action. 

The manufacturer has issued Boeing 

Special Attention Service Bulletin 777– 

71–0055, Revision 1, dated April 15, 

2015, which describes a modification 

that addresses the unsafe condition 

identified in this AD. This service 

information is an optional action in this 

AD. If final action is later identified, we 

might consider further rulemaking.

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 

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.

(d) Subject 

Air Transport Association (ATA) of 

America Code 54, Nacelles/pylons. 

(e) Unsafe Condition 

This AD was prompted by reports of 

blocked drain lines at the engine 

forward strut that caused flammable 

fluid to accumulate in a flammable 

leakage zone. We are proposing this AD 

to detect and correct blockage of 

forward strut drain lines, which could 

cause flammable fluids to collect in the 

forward strut area and potentially cause 

an uncontrolled fire or cause failure of 

engine attachment structure and 

consequent airplane loss. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless 

already done. 

(g) Functional Check, Cleaning, and 

Corrective Actions

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Empresa Brasileira de Aeronautica S.A. 

(Embraer) Model EMB–135BJ airplanes. 

This AD was prompted by a 

determination that more restrictive fuel 

limitations are needed. This AD requires 

revising the maintenance or inspection 

program to incorporate new compliance 

times and fuel limitations. We are 

issuing this AD to detect and correct 

fatigue cracking of various structural 

elements and prevent ignition sources 

in the fuel system. 

DATES: This AD becomes effective 

October 7, 2015. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Empresa Brasileira de 

Aeronautica S.A. (Embraer) Model 

EMB–135BJ airplanes. The NPRM 

published in the Federal Register on 

August 26, 2014 (79 FR 50857). The 

NPRM was prompted by a 

determination that more restrictive fuel 

limitations are needed. The NPRM 

proposed to require revising the 

maintenance or inspection program to 

incorporate new compliance times and 

fuel limitations. We are issuing this AD 

to detect and correct fatigue cracking of 

various structural elements and prevent 

ignition sources in the fuel system. 

The Ageˆncia Nacional De Aviac ̧a ̃o 

Civil (ANAC), which is the aviation 

authority for Brazil, has issued Brazilian 

Airworthiness Directive 2013–12–02, 

effective December 27, 2013 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Empresa Brasileira de 

Aeronautica S.A. (Embraer) Model 

EMB–135BJ airplanes. The MCAI states: 

This [Brazilian] AD was prompted by a 

new revision to the Airworthiness 

Limitations Requirements of the Maintenance 

Planning Guide (MPG–1483). We are issuing 

this [Brazilian] AD to allow timely detection 

and correction of fatigue cracking of various 

structural elements, and to allow the 

necessary preclusion of ignition sources in 

the fuel system. 

Required actions include revising the 

maintenance or inspection program, as 

applicable, to incorporate new 

compliance times and fuel limitations. 

You may examine the MCAI in the AD 

docket on the internet at http:// 

www.regulations.gov/#!docketDetail;

D=FAA-2014-0586. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 50857, August 26, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

50857, dated August 16, 2014) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 50857, 

dated August 16, 2014). 

Related Service Information Under 1 

CFR Part 51 

Embraer has issued the following 

service information.
