Rule

Airworthiness Directives; 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Airplanes

Action

Final Rule.

Summary

We are adopting a new airworthiness directive (AD) for all 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 airplanes. This proposed AD was prompted by several runway excursion incidents and a single accident where the power lever could not be operated as intended during the landing roll-out on Model Dornier 328-100 airplanes. This proposed AD would require a modification of the engine control box assembly. We are proposing this AD to prevent runway excursion, which could result in damage to the airplane and injury to the occupants.

SUPPLEMENTARY INFORMATION: Back to Top

Discussion Back to Top

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 31, 2011 (76 FR 54145). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Several runway excursion incidents and a single accident have occurred in the past with Dornier 328-100 aeroplanes, where the power lever could not be operated as intended during the landing roll-out. * * *

Recurrence of such an event under similar conditions, if not corrected, could result in further cases of runway excursion, possibly resulting in damage to the aeroplane and injury to the occupants.

A modification to the power lever control box [i.e., engine control box assembly] has been designed to prevent further power lever handling difficulties.

For the reasons described above, this [EASA] AD requires a modification of the power lever control box as a retrofit for the entire fleet of 328-100 aeroplanes.

The required actions also include revising the airplane flight manual (AFM) to include Dornier 328-100 Temporary Revisions (TR) 04-078, 04-079, and 04-080, all dated March 15, 2010, to the Abnormal Procedures section of the Dornier (328 Support Services) 328-100 AFM; and Dornier 328-100 TRs 05-064, 05-065, and 05-066, all dated February 13, 2009, to the Normal Procedures section of the Dornier (328 Support Services) 328-100 AFM. You may obtain further information by examining the MCAI in the AD docket.

Comments Back to Top

We gave the public the opportunity to participate in developing this AD. We considered the comment received.

Request To Change Work Hours Back to Top

328 Support Services GmbH requested we revise the Cost of Compliance section of the NPRM (76 FR 54145, August 31, 2011). The commenter stated that the estimate of 79 work-hours specified in the NPRM is too low and should be changed to 99 work-hours as specified in 328 Support Services Service Bulletin SB-328-76-486, Revision 3, dated April 7, 2010.

We agree that the number of work hours required is higher than our previous estimate. The cost impact information in this AD has been revised to indicate this higher amount.

Conclusion Back to Top

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information Back to Top

Although the MCAI specifies doing an inspection for discrepancies, 328 Support Services Service Bulletin SB-328-76-486, Revision 3, dated April 7, 2010, does not include this action. The off-wing inspection included in the MCAI is not required to address the unsafe condition. The modification addresses the identified unsafe condition. Therefore, this AD does not include that requirement.

Although the MCAI and service information do not include revising the AFM, this AD includes that requirement. The TRs specified below introduce pre-flight operational tests of the warning system modification, along with abnormal procedures that provide guidance to the flightcrew in the event of various potential warning system faults. These procedures must be adopted at the same time the modification is installed to ensure proper use and operation of the power lever warning system. This has been coordinated with EASA.

  • Dornier 320-100 TR 04-078, dated March 15, 2010, for the nuisance power lever aural alert.
  • Dornier 328-100 TR 04-079 and 04-080, both dated March 15, 2010, for the engine indication and crew alerting system (EICAS) caution “Proxi System.”
  • Dornier 328-100 TRs 05-064, 05-065, and 05-066, all dated February 13, 2009, for the power level aural alert test.

Costs of Compliance Back to Top

We estimate that this AD will affect 20 products of U.S. registry. We also estimate that it will take about 99 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $35,700 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $882,300, or $44,115 per product.

Authority for This Rulemaking Back to Top

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 Back to Top

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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
