Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2009-13-04 for RUAG Aerospace Services GmbH Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 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 excessive wear on the guide pin of the power lever or condition lever, which could cause functional loss of the flight idle stop. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective September 30, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of September 30, 2016.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to RUAG Aerospace Services GmbH Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes. That NPRM was published in the Federal Register on June 1, 2016 (81 FR 34927), and proposed to supersede AD 2009-13-04, Amendment 39-15943 (74 FR 29116; June 19, 2009) (“AD 2009-13-04”).

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 (EASA AD No.: 2009-0031R1) states that:

Excessive wear on a guide pin of a power lever was detected during inspections. The failure of a power lever or condition lever guide pin could cause functional loss of the flight idle stop.

This condition, if not corrected, could lead to inadvertent activation of the beta mode in flight, possibly resulting in loss of control of the aeroplane.

Prompted by this finding, RUAG issued Alert Service Bulletin (ASB) ASB-228-279 to provide inspection instructions. Consequently, EASA issued AD 2009-0031 to require repetitive detailed inspections of the guide pins of the power levers and condition levers, and replacement of any pin that exceeds the allowable wear-limits.

Since that AD was issued, further analysis has determined that the inspection interval, in case of no pin replacement, can be extended and RUAG published Revision 1 of ASB-228-279, which also included landings (expressed in this AD as flight cycles—FC) as a determining factor.

For the reason described above, this AD revises EASA AD 2009-0031, amending the compliance times without changing the technical requirements, and also introducing some editorial changes for standardization.

EASA revised the MCAI (EASA AD No.: 2009-0031R2) to incorporate changes to the applicability. The FAA had already incorporated these changes in the NPRM so no changes to the final rule are necessary.

The MCAI can be found in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-6983.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (74 FR 29116; June 19, 2009) 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 Start Printed Page 58830changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (74 FR 29116; June 19, 2009) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (74 FR 29116; June 19, 2009).

Related Service Information Under 1 CFR Part 51

We reviewed the RUAG Aerospace Services GmbH Dornier 228 Alert Service Bulletin No. ASB-228-279, revision 1, dated September 22, 2015. The service information describes procedures for repetitive inspections of the guide pins of the power and condition levers and replacement of those pins if necessary. 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 the AD.

Costs of Compliance

We estimate that this AD will affect 18 products of U.S. registry. We also estimate that it would take about 20 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $10 per product.

Based on these figures, we estimate the cost of the AD on U.S. operators to be $30,780, or $1,710 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 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.
