Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2011-21-06 for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 2011-21-06 required revising the maintenance program. This new AD requires a new revision of the maintenance or inspection program. This AD was prompted by a determination that the life limit of certain main landing gear components must be reduced, and certain post-repair inspections of critical structure are necessary. We are issuing this AD to prevent failure of certain structurally significant items, including the main landing gear and nose landing gear, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in a fuel tank explosion and consequent loss of the airplane.

DATES:

This AD is effective May 16, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 16, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of November 23, 2011 (76 FR 64788, October 19, 2011).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2011-21-06, Amendment 39-16829 (76 FR 64788, October 19, 2011) (“AD 2011-21-06”). AD 2011-21-06 applied to all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. The NPRM published in the Federal Register on May 8, 2015 (80 FR 26484) (“the NPRM”).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0043, dated February 21, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. The MCAI states:

The Jetstream J41 Aircraft Maintenance Manual (AMM), includes the following chapters:

05-10-10 “Airworthiness Limitations”,

05-10-20 “Certification Maintenance Requirements”, and,

05-10-30 “Critical Design Configuration Control Limitations (CDCCL)—Fuel System”.

The maintenance tasks and limitations contained in these chapters have been identified as mandatory actions for continued airworthiness and EASA issued AD 2010-0098 [dated May 27, 2010 (http://ad.easa.europa.eu/​ad/​2010-0098) which corresponds to FAA AD 2011-21-06, Amendment 39-16829 (79 FR 64788, October 19, 2011)] to require operators to comply with those instructions.

Since that [EASA] AD was issued, BAE Systems (Operations) Ltd issued Revision 37 of the AMM amending Chapter 05-10-10 to revise and reduce the life limit of certain main landing gear components. In addition, Revision 38 of the AMM was issued to amend Chapters 05-10-00 and 05-10-10 introducing inspections to be accomplished after implementation of some repairs affecting fatigue strength of critical structure. Failure to comply with the new and more restrictive actions could result in an unsafe condition.

For the reasons described above, this [EASA] AD, which supersedes EASA AD 2010-0098, requires implementation of the maintenance requirements and/or airworthiness limitations as specified in the defined parts of Chapter 05 of the AMM at Revision 38.

The unsafe condition is the failure of certain structurally significant items, including the main landing gear and nose landing gear, which could result in reduced structural integrity of the airplane; and fuel vapor ignition sources, which could result in a fuel tank explosion and consequent loss of the airplane. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-1279.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Explanation of Change to NPRM

Since we issued the NPRM, we discovered an incorrect reference to “paragraph (j)” in paragraph (i)(3) of the proposed AD. The correct reference is to “paragraph (i),” and we have changed this AD accordingly.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD with the change described previously and for minor editorial changes. We have determined that these changes:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

We reviewed Subjects 05-10-10, “Airworthiness Limitations”; 05-10-20, “Certification Maintenance Requirements”; and 05-10-30, “Critical Design Configuration Control Limitations (CDCCL)—Fuel System”; of Chapter 05, “Airworthiness Limitations,” of the BAE Systems (Operations) Limited J41 AMM, Revision 38, dated September 15, 2013. This service information describes procedures for inspections of structurally significant items and the fuel system. 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.Start Printed Page 21265

Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.

The actions required by AD 2011-21-06, Amendment 39-16829 (76 FR 64788, October 19, 2011), and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2011-21-06 is $85 per product.

We also estimate that it would take about 1 work-hour 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 this AD on U.S. operators to be $340, or $85 per product.

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 that 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.
