Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 and -300 series airplanes, that requires replacement of certain flight data recorder (FDR) and cockpit voice recorder (CVR) impact switches with certain new impact switches. This action is necessary to prevent the loss of data recorded on the FDR and CVR, which, in the event of an accident, could result in the inability to retrieve data from the FDR and CVR during the accident investigation. This loss of data could hinder the identification of the unsafe condition which caused the accident, and prevent the FAA from developing and mandating actions to prevent additional accidents caused by that same unsafe condition.

DATES:

Effective April 18, 2003.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of April 18, 2003.

SUPPLEMENTARY INFORMATION:

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Dornier Model 328-100 and -300 series airplanes was published in the Federal Register on December 10, 2002 (67 FR 75822). That action proposed to require replacement of certain flight data recorder (FDR) and cockpit voice recorder (CVR) impact switches with certain new impact switches.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public.

Conclusion

The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.

Cost Impact

The FAA estimates that 53 Model 328-100 series airplanes and 48 Model 328-300 series airplanes of U.S. registry would be affected by this AD, that it will take approximately 1 work hour per airplane to accomplish the required replacement, and that the average labor rate is $60 per work hour. Required parts will cost approximately $1,346 per airplane. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $142,006, or $1,406 per airplane.

The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions.

Regulatory Impact

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.

328-300 series airplanes3105 through 3223 inclusive.

Note 1:

This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance: Required as indicated, unless accomplished previously.

To prevent the loss of data recorded on the flight data recorder (FDR) and cockpit voice recorder (CVR), which, in the event of accident, could result in the inability to retrieve data from the FDR and CVR during the accident investigation, and hinder the identification of the unsafe condition which caused the accident, accomplish the following:

Switch Replacement

(a) For Model 328-100 series airplanes: Within 12 months after the effective date of this AD, replace the FDR and CVR 3g-impact switches, with new, 6g-impact switches, per the Accomplishment Instructions of Dornier Service Bulletin SB-328-31-390, dated September 6, 2001.

(b) For Model 328-300 series airplanes: Within 12 months after the effective date of this AD, replace the FDR and CVR 3g-impact switches, with new, 6g-impact switches, per the Accomplishment Instructions of Dornier Service Bulletin SB-328J-31-118, dated September 6, 2001.

Alternative Methods of Compliance

(c) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Operations Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116.

Note 2:
