Start Preamble

AGENCY:

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

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, -300F, and -400ER series airplanes. The existing AD currently requires an inspection to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This proposed AD would add airplanes and, for certain airplanes, require additional inspections to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source inside the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

DATES:

We must receive comments on this proposed AD by April 28, 2011.

Discussion

On October 19, 2009, we issued AD 2009-22-13, amendment 39-16066 (74 FR 55755, October 29, 2009), for certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes. That AD requires an inspection to determine if certain motor operated valve (MOV) actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. That AD resulted from fuel system reviews conducted by the manufacturer. We issued that AD to prevent an ignition source inside the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Actions Since Existing AD Was Issued

Since we issued AD 2009-22-13, Boeing issued a revision to Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008 (which was referenced as a source of service information in AD 2009-22-13). Boeing Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010, corrects the group configuration assignment for certain airplanes, adds airplanes to the effectivity, and adds additional work for certain airplanes that accomplished Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008; or Boeing Service Bulletin 767-28A0090, Revision 1, dated April 1, 2010. The actions described in Boeing Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010, are similar to those described in Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008.Start Printed Page 13535

The airplanes that were assigned to the wrong group configuration (Group 3 instead of Group 2) and accomplished the requirements of AD 2009-22-13 in accordance with Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008, need to do additional inspections to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary, in accordance with Boeing Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010 (the new group configuration has more work packages than the old group configuration).

The airplanes that were assigned to the wrong group configuration (Group 4 instead of Group 1) in Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008; or Boeing Service Bulletin 767-28A0090, Revision 1, dated April 1, 2010; and accomplished actions using either of those service bulletins need to do additional inspections to determine if certain MOV actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary, in accordance with Boeing Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010 (the new group configuration has more work packages than the old group configuration).

FAA's Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to develop on other airplanes of the same type design. For this reason, we are proposing this AD, which would supersede AD 2009-22-13 and would retain the requirements of the existing AD. This proposed AD would also require, for certain airplanes, accomplishing the actions specified in the Boeing Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010, described previously.

Costs of Compliance

There are about 398 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this proposed AD.

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspection for presence of MOV actuators (required by AD 2009-22-13)Between 2 and 4 work-hours × $85 per hour = Between $170 and $340noneBetween $170 and $340Between $67,660 and $135,320.

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 have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:

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); 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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
