**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  We are superseding airworthiness directive (AD) 87–02–07, which applied to all The Boeing Company Model 737–100 and –200 series airplanes. AD 87–02–07 required replacement of certain underwing fueltank access covers with stronger, fireresistant covers. This new AD also requires inspecting fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations, inspecting application ofstencils and index markers of impactresistant access doors, doing corrective actions if necessary, revising the maintenance program, and adding airplanes to the applicability. This AD was prompted by reports of standardaccess doors installed where impactresistant access doors are required, and reports of impact-resistant doors without stencils. We are issuing this AD to prevent foreign object penetration of the wing tank, which could lead to a fuel leak near ignition sources (engine, hot brakes), consequently leading to a fuel-fed fire.

**DATES :**  This AD is effective August 20,
2013.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 20, 2013.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 87–02–07, Amendment 39–5506 (Docket No. 86– NM–175–AD; 52 FR 518, January 7, 1987), (‘‘AD 87–02–07’’). AD 87–02–07 applied to the specified products. The NPRM published in the Federal Register on April 10, 2013 (78 FR 21279). The NPRM proposed to continue to require replacement of certain underwing fuel tank access covers with stronger, fire-resistant covers. The NPRM also proposed to require inspecting fuel tank access doors to determine that impact-resistant access doors are installed in the correct


### 42416 Federal Register / Vol. 78, No. 136 / Tuesday, July 16, 2013 / Rules and Regulations

locations, inspecting application ofstencils and index markers of impactresistant access doors, doing corrective actions if necessary, revising the maintenance program, and adding airplanes to the applicability.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Concurrence With NPRM (78 FR 21279, April 10, 2013)

Boeing stated that it concurs with the content of the NPRM (78 FR 21279, April 10, 2013).

Conclusion

We reviewed the relevant data, considered the comment 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 NPRM (78 FR 21279, April 10, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 21279, April 10, 2013). Costs of Compliance

We estimate that this AD affects 128 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspect, replace, and apply stencil and index

Revise maintenance program ......................... 1 work-hour × $85 per hour = $85 ................ 0 85 10,880

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 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.
List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2013– 0115–E, dated May 28, 2013 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:
Reports have been received that rivets with insufficient shear (about 50% shear allowable) were delivered from the supplier
