ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for British 

Aerospace Regional Aircraft Jetstream 

Series 3101 and Jetsream 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 

missing countersunk washers under the 

head of the main landing gear trunnion 

cap tension bolts that could cause 

fatigue in the bolt shanks. 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 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://

www.regulations.gov/

#!documentDetail;D=FAA-2015-2048-

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 32510, June 9, 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 

32510, June 9, 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 32510, 

June 9, 2015). 

Related Service Information Under 1 

CFR Part 51 

We reviewed British Aerospace 

Regional Aircraft British Aerospace 

Jetstream Series 3100 & 3200 Service 

Bulletin 57–JA120141, REVISION 1, 

dated April 8, 2014. The service 

information describes procedures for 

inspection and replacement of main 

landing gear trunnion cap tension bolts. 

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 

66 products of U.S. registry. We also 

estimate that it will take about 6 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 $33,660, or $510 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 1 work-hour and require parts 

costing $1,200, for a cost of $1,285 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 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.

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: 

2015–16–05 British Aerospace Regional 

Aircraft: Amendment 39–18230; Docket 

No. FAA–2015–2048; Directorate 

Identifier 2015–CE–015–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 Series 3101 and 

Jetsream Model 3201 airplanes, all serial 

numbers, certificated in any category. 

(d) Subject

condition on an aviation product. The MCAI 

describes the unsafe condition as missing 

countersunk washers under the head of the 

main landing gear (MLG) trunnion cap 

tension bolts that could cause fatigue in the 

bolt shanks. We are issuing this AD to detect 

and correct missing countersunk washers, 

which 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 airplane and injury 

to occupants. 

(f) Actions and Compliance 

Unless already done, do the actions in 

paragraphs (f)(1) through (f)(4) of this AD, 

including all subparagraphs, following the 

Accomplishment Instructions in British 

Aerospace Jetstream Series 3100 & 3200 

Service Bulletin 57–JA120141, REVISION 1,

ACTION: Final rule. 

SUMMARY: This action expands the 

lateral boundary of restricted area R– 

3804B, Fort Polk, LA, and raises the 

restricted area ceiling to, but not 

including 10,000 feet mean sea level 

(MSL). The expanded restricted area 

airspace will contain new live fire 

ranges to support mission requirements 

of the U.S. Army in order to fully 

exploit the capabilities of modern 

weapons systems and complex training 

scenarios that replicate conditions 

encountered during military 

deployments today. This action also 

amends time of designation for R– 

3804A and R–3804B to better reflect 

when the restricted areas are in use by 

the U.S. Army and when the airspace is 

available to nonparticipants. Lastly, this
