**SUPPLEMENTARY INFORMATION**

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to all British Aerospace Regional Aircraft Jetstream Model 3201 airplanes. That NPRM was published in the Federal Register on April 14, 2014 (79 FR 20832), and proposed to supersede AD 2007–10–16, Amendment 39–15057 (72 FR 27953, May 18, 2007).

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 Series 3200 Aircraft Maintenance Manual (AMM), includes Chapter 05–10–05 ‘‘Airworthiness Limitations, Description and Operation’’. The maintenance tasks and limitations contained in this chapter have been identified as mandatory actions for continued airworthiness and EASA issued AD 2007– 0074 to require operators to comply with those instructions.

Since that AD was issued, BAE Systems (Operations) Ltd amended Jetstream Series 3200 AMM Chapter 05–10–05 to introduce life limitations for the main landing gear radius rod mounting shaft assemblies and to incorporate wing structure inspections previously introduced through BAE Systems (Operations) Ltd Service Bulletin (SB) SB 51– JA020940. In addition, a new table was introduced to provide extended fatigue life limitations for structural items for aeroplanes entered into a life extension programme. Reference to BAE Systems (Operations) Ltd SB 32–JA981042 was updated from Revision 7 to Revision 8 to reflect increased life limits of the nose landing gear.

Failure to comply with the new and more restrictive instructions could result in an unsafe condition.

For the reasons described above, this EASA AD retains the requirements of EASA AD 2007–0074, which is superseded, and requires implementation of the maintenance requirements and/or airworthiness limitations as specified in Chapter 05–10–05 of the Jetstream Series 3200 AMM at Revision
29.


### The MCAI can be found in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0241-
0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 20832, April 14, 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 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 (79 FR 20832, April 14, 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 20832, April 14, 2014). Costs of Compliance

We estimate that this AD will affect 14 products of U.S. registry. We alsoestimate that it will take about 1 workhour per product to comply with the basic requirements of this AD of inserting the document into the Airworthiness Limitations section of the Instructions for Continued Airworthiness. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $1,190, or $85 per product.

We have no way of determining the cost to replace the life limited parts and to do the applicable maintenance tasks on each airplane. 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. Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0241; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the **ADDRESSES** 

### section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39
