Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2004-06-01, which applied to certain Dornier Model 328-100 series airplanes; and AD 2009-06-09, which applied to all Dornier Model 328-100 series airplanes. AD 2004-06-01 required replacement of the existing main landing gear (MLG) leg assembly with a modified assembly. AD 2009-06-09 required modifying the MLG main body and trailing arm bushings, and revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD continues to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective May 26, 2020.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 26, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0270, dated October 30, 2019 (“EASA AD 2019-0270”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all 328 Support Services GmbH Model 328-100 airplanes.

EASA AD 2019-0270 also specifies that it takes over the applicable requirements of EASA AD 2006-0197, dated July 11, 2006 (which corresponds to FAA AD 2008-17-01 R1, Amendment 39-16106 (74 FR 63569, December 4, 2009) (“AD 2008-17-01 R1”); and EASA AD 2010-0054, dated March 25, 2010 (which corresponds to Start Printed Page 21758FAA AD 2012-01-08, Amendment 39-16920 (77 FR 3583, January 25, 2012) (“AD 2012-01-08”). Accomplishing the existing maintenance or inspection program revision required in this AD terminates the requirements of AD 2008-17-01 R1 and AD 2012-01-08 for Model 328-100 series airplanes.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2004-06-01, Amendment 39-13527 (69 FR 13715, March 24, 2004) (“AD 2004-06-01”); and AD 2009-06-09, Amendment 39-15845 (74 FR 12249, March 24, 2009) (“AD 2009-06-09”). AD 2004-06-01 applied to certain Dornier Model 328-100 series airplanes; and AD 2009-06-09, applied to all Dornier Model 328-100 series airplanes. The NPRM published in the Federal Register on February 3, 2020 (85 FR 5906). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a EASA AD. The FAA is issuing this AD to address the potential failure of parts, which could lead to reduced control of the airplane; and to address the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.

Clarification of Paragraph (i) of This AD

Once the existing maintenance or inspection program is revised as required by paragraph (g) of this AD, paragraph (i) of this AD does not allow for the later use of alternative actions or intervals unless these alternative actions or intervals are approved as specified in “Ref. Publications” section of EASA AD 2019-0270. Paragraph (i) of the proposed AD used the word “except” to describe the allowance for alternative actions or intervals. To make the language consistent with the language in the “Ref. Publications” section of EASA AD 2019-0270, the FAA has changed the wording to “unless they are approved.”

Conclusion

The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:

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

Related IBR Material Under 1 CFR Part 51

EASA AD 2019-0270 describes, among other actions, airworthiness limitations for certification maintenance requirements that include, among other items, safe life limits and fuel tank system limitations. This material 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.

Costs of Compliance

The FAA estimates that this AD affects 21 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the agency has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. The FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours × $85 per work-hour).

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.

The FAA is 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

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) Will not affect intrastate aviation in Alaska, and

(3) 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.
