**Airworthiness Directives; the Boeing Company Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are superseding Airworthiness Directive (AD) 89–12–10, for certain The Boeing Company Model 747 airplanes. AD 89–12–10 required replacement of certain underwing fueltank access doors with stronger, fireresistant doors. This new AD requires inspecting certain fuel tank access doors for installation of impact-resistant doors, and stencils and index markers; corrective actions if necessary; revising the maintenance program to incorporate certain new airworthiness limitations; and adding airplanes to the applicability. This AD was prompted by a report of a standard access door installed instead of an impact-resistant access door and stencils missing from some impact-resistant access doors and adjacent wing skin. We are issuing this AD to prevent foreign object penetration of the fuel tank, 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.

**DATES :**  This AD is effective September 9,
2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 9, 2014.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 89–12–10, Amendment 39–6230 (Docket No. 88– NM–57–AD; 54 FR 23643, June 2, 1989). AD 89–12–10 applied to certain The Boeing Company Model 747 100, 747– 200, 747–300, and 747SP series airplanes. The NPRM published in the Federal Register on September 25, 2013 (78 FR 58962). 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 and adjacent wing skin. 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 replacement of any standard door with an impact-resistant access door if necessary. The NPRM also proposed to require an inspection for the presence ofstencils and index markers on impactresistant access doors, and application of new stencils or index markers if necessary. The NPRM also proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. The NPRM also proposed to add airplanes to the applicability. We are issuing this AD to prevent foreign object penetration of the fuel tank, 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. The following presents the comments received on the proposal (78 FR 58962, September 25, 2013) and the FAA’s response to each comment.
Request To Revise Maintenance Planning Data (MPD) Document Number

United Airlines requested that we revise the MPD document number specified in paragraph (h)(1) of the NPRM (78 FR 58962, September 25, 2013) to reference Boeing 747–400 MPD Document D621U400–9, Revision August 2012. United Airlines pointed out that the airworthiness section of the document is located in Section 9 of the document identified as D621U400–9.

We agree with the commenter for the reason provided. We have revised paragraph (h)(1) of this final rule accordingly. Request To Reference Aircraft Maintenance Manual (AMM)

British Airways (BA) stated the AMM would be a better location for an appropriate task than the maintenance program. BA stated that Task 57–AWL– 01, ‘‘Impact-Resistant Fuel Tank AccessDoors,’’ of Sub-section B.2, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Section B, ‘‘Airworthiness Limitations (AWLs)—Fuel Systems,’’ of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), of the D621U400–9 Boeing 747–400 Maintenance Planning Data (MPD) Document D621U400–9, Revision August 2012, does not have a fixed interval or a defined inspection type, but simply requires that the access panels are verified to be impact resistant prior to installation. BA stated that this cannot be described as scheduled maintenance and does not consider the best place for this Critical Design Configuration Control Limitation (CDCCL) to be an operator’s maintenance program. BA stated that many CDCCL items are satisfied through the AMM rather than with a maintenance program task. BA gave an example of CDCCL Task 28–AWL–16, ‘‘Fuel Tank Access Doors Configuration’’ of Sub-section B.1, ‘‘AWLs—Fuel System Ignition Prevention,’’ of Section B, ‘‘Airworthiness Limitations (AWLs)— Fuel Systems,’’ of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), of the D621U400–9 Boeing 747–400 Maintenance Planning Data (MPD) Document D621U400–9, Revision August 2012, which also relates to fuel tank access door installation and has no fixed interval; however, this CDCCL requirement is satisfied through the AMM procedure relating to these panels, and not through a task in an operator’s maintenance
program.

We infer that the commenter is requesting that Task 57–AWL–01, ‘‘Impact-Resistant Fuel Tank AccessDoors,’’ of Sub-section B.2, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Section B, ‘‘Airworthiness Limitations (AWLs)—Fuel Systems,’’ of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), of the D621U400–9 Boeing 747–400 Maintenance Planning Data (MPD) Document D621U400–9, Revision August 2012, contain a reference to the AMM similar to CDCCL Task 28–AWL–16, ‘‘Fuel Tank Access Doors Configuration’’ of Sub-section B.1, ‘‘AWLs—Fuel System Ignition Prevention,’’ of Section B, ‘‘Airworthiness Limitations (AWLs)— Fuel Systems,’’ of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), of the D621U400–9 Boeing 747–400 Maintenance Planning Data (MPD) Document D621U400–9, Revision August 2012.

We disagree with the request to add an AMM reference. The requirement specified in Task 57–AWL–01 identifies the safety critical item to be maintained and does not mandate a specific AMM. The inclusion of a reference to an AMM is not necessary. However, operators may refer to the AMMs that are referenced in CDCCL Task 28–AWL–16. We have not changed this AD in this regard.
Clarification of Inspection Area

Paragraph (g)(2) of the NPRM (78 FR 58962, September 25, 2013) proposed to require an inspection for the presence ofstencils and index markers on impactresistant access doors, and application of new stencils or index markers if necessary. As specified in Boeing Service Bulletin 747–28–2315, dated January 11, 2012, the stencils and index markers are located on the doors and adjacent wing skin. Therefore, we have revised paragraph (g)(2) of this AD to specify doing an inspection for the presence of stencils and index markers on impact-resistant access doors and adjacent wing skin. We have also clarified in the **SUMMARY** section and Discussion paragraph of the

**SUPPLEMENTARY INFORMATION** section that the AD was prompted by a report of a standard access door installed instead of an impact-resistant access door and stencils missing from some impact-resistant access doors and adjacent wing skin.
Clarification of Maintenance Program Revision

Paragraph (h) of the NPRM (78 FR 58962, September 25, 2013) specifies that the actions specified in paragraphs (h)(1) and (h)(2) of the NPRM must be done; however, the affected airplane models were not identified. We have revised paragraph (h)(1) of this AD to specify that the actions are applicable for Model 747–400, 747–400D, 747– 400F series airplanes. We have also revised paragraph (h)(2) of this AD to specify that the actions are applicable for Model 747–100, 747–100B, 747– 100B SUD, 747–200B, 747–200C, 747– 200F, 747–300, 747SR, and 747SP series airplanes.


### 45326 Federal Register / Vol. 79, No. 150 / Tuesday, August 5, 2014 / Rules and Regulations

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 58962, September 25, 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 58962, September 25, 2013).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.
Costs of Compliance

We estimate that this AD affects 189 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

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

Inspection .......................................... Up to 13 work-hours × $85 per hour = $1,105 ........... $0 Up to $1,105 ..... Up to $208,845. Maintenance program revision .......... 1 work-hour × $85 per hour = $85 .............................. $0 $85 ................... $16,065.

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:



### O N 

### -C ONDITION 

### C OSTS

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 (14 doors) ............................ 17 work-hours × $85 per hour = $1,445 ...................... $0 1,445

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

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

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for Fuji Heavy Industries, Ltd. Models FA–200– 160, FA–200–180, and FA–200–180AO airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as deterioration of brake performance due to seal defects caused by deterioration due to age of the O-rings of the brake master cylinder. We are issuing this AD to require actions to address the unsafe condition on these products.

**DATES :**  This AD is effective September 9,
2014.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of September 9, 2014.
