Aerospace Regional Aircraft Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2007–08– 

06 for British Aerospace Regional 

Aircraft Models HP.137 Jetstream Mk.1, 

Jetstream Series 200 and 3101, and 

Jetstream Model 3201 airplanes. This 

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 the need for airworthiness 

limitations for critical components in 

the main and nose landing gear 

assemblies. We are issuing this 

proposed AD to require actions to 

address the unsafe condition on these 

products.

Discussion 

We issued AD 2007–08–06, 

Amendment 39–15023 (72 FR 18565; 

April 13, 2007) (‘‘AD 2007–08–06’’). 

That AD required actions intended to 

address an unsafe condition on British 

Aerospace Regional Aircraft Models 

HP.137 Jetstream Mk.1, Jetstream Series 

200 and 3101, and Jetstream Model 3201 

airplanes and was based on mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country. 

Since we issued AD 2007–08–06, new 

part numbers have been introduced into 

service that allow for a change in the life 

limits requirements in the airworthiness 

limitations. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No.: 

2017–0157, dated August 25, 2017 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

The airworthiness limitations for critical 

Main Landing Gear and Nose Landing Gear 

components installed on Jetstream 3100 and 

3200 aeroplanes, which are approved by 

EASA, are currently defined and published 

in BAE Systems (Operations) Ltd Service 

Bulletin (SB) 32–JA981042. These 

instructions have been identified as 

mandatory actions for continued 

airworthiness. Failure to accomplish these 

instructions could result in an unsafe 

condition. 

Previously, EASA issued AD 2006–0087 to 

require implementation of the airworthiness 

limitations for critical landing gear 

components as specified in BAE Systems 

(Operations) Ltd SB 32–JA981042 at Revision 

5. 

Since that AD was issued, two new Part 

Numbers (P/N) were introduced into service 

(alternative port and starboard axles P/N 

AIR141958 and P/N AIR141959 specific to 

Jetstream 3200). Consequently, BAE Systems 

(Operations) Ltd published SB 32–JA981042 

Revision 7 (later revised) to introduce the 

associated life limits, and to introduce a life 

limit for the steering jack piston, which was 

found missing in the SB at Revision 5. 


ethrower on DSK3G9T082PROD with PROPOSALS
Federal Register / Vol. 82, No. 204 / Tuesday, October 24, 2017 / Proposed Rules 49145 

For the reason described above, this 

[EASA] AD retains the requirements of AD 

2006–0087, which is superseded, and 

requires implementation of the airworthiness 

limitations as specified in BAE Systems 

(Operations) Ltd SB 32–JA981042 at Revision 

9 (hereafter referred to as ‘the SB’ in this AD). 

Related Service Information Under 1 

CFR Part 51 

BAE Systems (Operations) Limited 

has issued British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 32– 

JA981042, Revision No. 9, dated July 11, 

2017, which contains instructions for 

replacing main landing gear 

components within specified life limits. 

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 NPRM. 

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. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 26 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours 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 $4,420, or $170 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 6 work-hours and require parts 

costing $5,000, for a cost of $5,510 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to small airplanes and 

domestic business jet transport 

airplanes to the Director of the Policy 

and Innovation Division. 

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), 

(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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 

removing Amendment 39–15023 (72 FR 

18565; April 13, 2007), and adding the 

following new AD: 

British Aerospace Regional Aircraft: Docket 

No. FAA–2017–0993; Product Identifier 

2017–CE–026–AD. 

(a) Comments Due Date 

We must receive comments by December 8, 

2017. 

(b) Affected ADs 

This AD replaces AD 2007–08–06, 

Amendment 39–15023 (72 FR 18565; April 

13, 2007) (‘‘2007–08–06’’). 

(c) Applicability 

This AD applies to British Aerospace 

Regional Aircraft Models HP.137 Jetstream 

Mk.1, Jetstream Series 200 and 3101, and 

Jetstream Model 3201 airplanes, all serial 

numbers, certificated in any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 32: Landing Gear. 

(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 need for 

airworthiness limitations for critical 

components in the main and nose landing 

gear assemblies. We are issuing this AD to 

introduce new replacement part numbers and 

incorporate new limitations for the 

replacement part numbers to prevent failure 

of the main and nose landing gear, which 

could result in loss of control. 

(f) Actions and Compliance 

Unless already done, do the following 

actions listed in paragraphs (f)(1) through (4) 

of this AD: 

(1) For all affected airplane models: Before 

further flight after the effective date of this 

AD, replace each component part in the main 

and nose landing gear assemblies as 

applicable to airplane model and 

configuration before exceeding the applicable 

life limit, following the Accomplishment 

Instructions in BAE Systems British 

Aerospace Jetstream Series 3100 and 3200 

Service Bulletin 32–JA981042 Rev 9, dated 

July 11, 2017. 

(2) For the affected Model Jetstream 3201 

airplanes: Within 50 hours after the effective 

date of this AD, replace alternative port and 

starboard axles part numbers (P/N) 

AIR141958 and P/N AIR141959 that have 

exceeded the applicable life limits as shown 

in table 5 of BAE Systems British Aerospace 

Jetstream Series 3100 and 3200 Service

Bulletin 32–JA981042 Rev 9, dated July 11, 

2017. 

(3) For all affected airplane models: Before 

further flight after the effective date of this 

AD, revise the FAA-approved maintenance 

program (instructions for continued 

airworthiness) on the basis of which the 

operator or the owner ensures the continuing 

airworthiness of each operated airplane, as 

applicable to the airplane model, by 

incorporating the limitations described in 

BAE Systems British Aerospace Jetstream 

Series 3100 and 3200 Service Bulletin 32– 

JA981042 Rev 9, dated July 11, 2017, as 

applicable to the airplane model and 

depending on the airplane configuration. 

(4) For all airplanes: The compliance times 

in paragraphs (f)(1) and (2) of this AD are 

presented in flight cycles (landings). If the 

total flight cycles have not been kept, 

multiply the total number of airplane hours 

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

cycles. For the purposes of this AD: 

(i) 100 hours TIS × .75 = 75 cycles; and 

(ii) 1,000 hours TIS × .75 = 750 cycles. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A318–111 and –112 

airplanes; Model A319–111, –112, –113, 

–114, and –115 airplanes; Model A320– 

211, –212, –214, and –216 airplanes; 

and Model A321–111, –112, –211, –212, 

and –213 airplanes. This proposed AD 

was prompted by a review of 

maintenance instructions for a blend 

repair of the snout diameter of the main 

beam assembly of the forward engine 

mount that would create an excessive 

gap between the bearing mono-ball and 

the snout. This proposed AD would 

require modifying the main beam 

assembly of the forward engine mount. 

We are proposing this AD to address the 

unsafe condition on these products.
