2014-22979. Airworthiness Directives; The Boeing Company Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, -300F, and -400ER airplanes. This AD was prompted by reports indicating that a standard access door was located where an impact-resistant access door was required, and stencils were missing from some impact-resistant access doors. This AD requires an inspection of the wing fuel tank access doors to determine whether impact-resistant access doors are installed in the correct locations, and to replace incorrectly installed doors with impact-resistant access doors. This AD also requires an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. In addition, this AD requires revising the maintenance program to incorporate changes to the airworthiness limitations section. We are issuing this AD to correct the unsafe condition on these products.

DATES:

This AD is effective November 5, 2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 5, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 767-200, -300, -300F, and -400ER airplanes. The SNPRM published in the Federal Register on July 2, 2014 (79 FR 37681). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on August 12, 2013 (78 FR 48826). The NPRM proposed to require an inspection of the left-and right-hand wing fuel tank access doors to determine whether impact-resistant access doors are installed in the correct locations, and to replace incorrectly installed doors with impact-resistant access doors. The NPRM also proposed to require an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. In addition, the NPRM proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. The NPRM was prompted by reports indicating that a standard access door was located where an impact-resistant access door was required, and stencils were missing from some impact-resistant access doors. The SNPRM proposed to revise the NPRM by adding airplanes to the applicability. We are issuing this AD to prevent foreign object penetration of the fuel tank from uncontained engine failure or tire debris, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comments received. Boeing and FedEx Express supported the SNPRM (79 FR 37681, July 2, 2014).

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed, except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the SNPRM (79 FR 37681, July 2, 2014) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the SNPRM (79 FR 37681, July 2, 2014).

Costs of Compliance

We estimate that this AD affects 436 airplanes of U.S. registry. We estimate the following costs to comply with this AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Inspection	Up to 7 work-hours × $85 per hour = $595	$0	$595	$259,420
Maintenance program revision	1 work-hour × $85 per hour = $85	0	85	37,060

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements:

On-Condition Costs

Action	Labor cost	Parts cost	Cost per product
Replacement per door	3 work-hours × $85 per hour = $255	$8,000	$8,255
Stencil and index marker	9 work-hours × $85 per hour = $765	0	765

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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

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 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.
