Airworthiness Directives; British 

Aerospace Regional Aircraft Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for British 

Aerospace Regional Aircraft Model 

Jetstream Model 3201 airplanes. This 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued 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 the in-service special 

detailed inspection technique required 

for the Jetstream 3200’s life extension 

program was delayed; consequently, the 

in-service special detailed inspection 

technique is not formally part of the life 

extension program and may therefore 

not be accomplished as intended. We 

are issuing this AD to require actions to 

address the unsafe condition on these 

products. 

DATES: This AD is effective September 

21, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of September 21, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to adding an AD that would 

apply to British Aerospace Regional 

Aircraft Model Jetstream Model 3201 

airplanes. The NPRM was published in 

the Federal Register on May 26, 2015 

(80 FR 29988). The NPRM proposed to 

correct an unsafe condition for the 

specified products and was based on 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country. 

The MCAI states: 

The Jetstream 3200 Life Extension 

Programme (LEP) permits the airframe life 

limit to be extended from 45 000 flight cycles 

(FC) to 67 000 FC. Entry into the LEP requires 

operators to accomplish inspections specified 

in the Jetstream 3200 Supplemental 

Structural Inspections Document (SSID). 

SSID task 57–10–227 is the inspection 

requirement for the wing main spar at Rib 36. 

The threshold for task 57–10–227 is 48 000 

FC, with a repeat interval of 16 800 FC, using 

a Special Detailed Inspection (SDI). 

Development of the in-service SDI technique 

required for SSID task 57–10–227 was 

delayed by BAE Systems (Operations) Ltd, as 

a result of which it is not formally part of the 

LEP and may therefore not be accomplished 

as intended. 

This condition, if not corrected, could lead 

to cracks in the wing main spar remaining 

undetected, possibly resulting in failure of 

the wing and loss of the aeroplane. 

To address this potential unsafe condition, 

BAE Systems (Operations) Ltd issued SB 57– 

JA140140 to provide SDI instructions for the 

wing main spar at Rib 36, which includes a 

reduced repeat inspection interval. 

For the reasons described above, this AD 

requires repetitive inspections of the wing 

main spar around Rib 36 to detect cracks and, 

depending on findings, accomplishment of 

the applicable corrective action(s). 

The SSID will be revised in due 

course to include the SDI. The MCAI 

can be found in the AD docket on the 

Internet at: http://www.regulations.gov/

#!documentDetail;D=FAA-2015-1744- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 29988, May 26, 2015) 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 the 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 (80 FR 

29988, May 26, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 29988, 

May 26, 2015). 

Related Service Information Under 1 

CFR Part 51 

We reviewed British Aerospace 

Regional Aircraft British Aerospace 

Jetstream Series 3100 & 3200 Service 

Bulletin 57–JA140140, Original Issue, 

dated: June 26, 2014. The service 

information describes procedures for 

inspections of the wing main spar 

around Rib 36 to detect cracks and, 

depending on findings, accomplishment 

of the applicable corrective action(s). 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section of 

this AD. 

Costs of Compliance 

We estimate that this AD will affect 

22 products of U.S. registry. We also 

estimate that it will take about 96 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $179,520, or $8,160 per product. 

We have no way of determining any 

necessary follow-on actions, costs, or 

the number of products that may need 

these actions. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 80, No. 158 / Monday, August 17, 2015 / Rules and Regulations 49131 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591. ATTN: Information 

Collection Clearance Officer, AES–200. 

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 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 this AD: 

(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.

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: 

2015–16–06 British Aerospace Regional 

Aircraft: Amendment 39–18231; Docket 

No. FAA–2015–1744; Directorate 

Identifier 2015–CE–016–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective September 21, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to British Aerospace 

Regional Aircraft Jetstream Model 3201 

airplanes, all serial numbers, that are: 

(1) Certificated in any category; and 

(2) Modified in service following BAE 

Systems (Operations) Ltd Service Bulletin 

(SB) 05- JM8229. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 57: Wings. 

(e) Reason 

This AD was prompted by 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 the inservice special detailed inspection technique 

required for the Jetstream 3200’s life 

extension program was delayed; 

consequently, the in-service special detailed 

inspection (SDI) technique is not formally 

part of the life extension program and may 

therefore not be accomplished as intended. 

We are issuing this AD to detect and correct 

cracking in the wing main spar, which could 

result in structural failure of the wing with 

consequent loss of control. 

(f) Actions and Compliance 

Unless already done, do the following 

actions as specified in paragraphs (f)(1) 

through (f)(3) of this AD: 

(1) Before accumulating a total of 53,950 

flight cycles (FC) on the airplane or within 

the next 50 FC after September 21, 2015 (the 

effective date of this AD), whichever occurs 

later, and repetitively thereafter at intervals 

not to exceed 14,300 FC, accomplish an eddy 

current (EC) and an x-ray inspection of the 

wing main spar around rib 36 following the 

instructions of British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 57– 

JA140140, Original Issue, dated June 26, 

2014. For the purposes of this AD, owner/

operators who do not track total FC must 

multiply the total number of airplane hours 

time-in-service (TIS) by 0.75 to calculate the 

cycles. 

(2) If any crack or corrosion is found 

during any inspection required by paragraph 

(f)(1) of this AD, before further flight, contact 

BAE Systems (Operations) Ltd for FAAapproved repair instructions approved 

specifically for this AD and accomplish those 

instructions. You can find contact 

information for BAE Systems (Operations) 

Ltd in paragraph (i)(3) of this AD. Use the 

Operator Report Form and follow the 

instructions in British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 57– 

JA140140, Original Issue, dated: June 26, 

2014. 

(3) Repair of an airplane as required in 

paragraph (f)(2) of this AD does not terminate 

the repetitive inspections required in 

paragraph (f)(1) of this AD for that airplane, 

unless the approved repair instructions state 

otherwise. 

(g) Other FAA AD Provisions 

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

4090; email: email: doug.rudolph@faa.gov. 

Before using any approved AMOC on any 

airplane to which the AMOC applies, notify 

your appropriate principal inspector (PI) in 

the FAA Flight Standards District Office 

(FSDO), or lacking a PI, your local FSDO. 

(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 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to adding an AD that would 

apply to British Aerospace Regional 

Aircraft Model Jetstream Series 3101 

and Jetstream Model 3201 airplanes. 

The NPRM was published in the 

Federal Register on June 9, 2015 (80 FR 

32510). The NPRM proposed to correct 

an unsafe condition for the specified 

products and was based on mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country. 

The MCAI states: 

The review of the BAE production drawing 

for main landing gear (MLG) fitting 

installation identified a risk of omitting 

installation of a countersunk washer under 

the head of the MLG trunnion cap tension 

bolts, potentially causing fatigue in the bolt 

shank under the head of such tension bolt(s). 

This condition, if not detected and 

corrected, could lead to failure of the bolt(s), 

thereby compromising the structural integrity 

of the other MLG tension bolts holding the 

MLG in place, possibly resulting in collapse 

of the MLG on take-off or landing with 

consequent damage to the aeroplane and 

injury to occupants. 

Although so far, no in-service bolt head 

failures have been reported since entry in to 

service of the type design in 1986, to address 

this potential unsafe condition, BAE Systems 

(Operations) Ltd issued Service Bulletin (SB) 

57–JA120141 to provide inspection 

instructions. 

For the reasons described above, this AD 

requires inspection and, depending on 

findings, replacement of the MLG trunnion 

cap tension bolts. 

The MCAI can be found in the AD 

docket on the Internet at: http://
