AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.

SUMMARY:

We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. The NPRM proposed to supersede AD 2003-13-01, which currently requires an inspection to detect cracks and fractures of the outboard hinge fitting assemblies on the trailing edge of the inboard main flap, and follow-on and corrective actions if necessary. For certain airplanes, AD 2003-13-01 also requires inspecting to determine if a tool runout option has been performed in the area. The NPRM proposed to reduce a certain compliance time and adds airplanes to the applicability. The NPRM also provided optional terminating action for certain inspections. The NPRM was prompted by reports of hinge assembly fractures found before certain required compliance times in AD 2003-13-01. This action revises the NPRM by reducing repetitive inspection intervals for certain airplanes and limiting the inspection area. We are proposing this supplemental NPRM (SNPRM) to prevent the inboard aft flap from separating from the wing and potentially striking the airplane, which could result in damage to the surrounding structure and potential personal injury. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

DATES:

We must receive comments on this SNPRM by November 13, 2014.

Discussion

We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 767-200, -300, and -300F, and -400ER series airplanes. The NPRM published in the Federal Register on February 9, 2012 (77 FR 6685). The NPRM proposed to supersede AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003). The NPRM proposed to continue to require an inspection to detect cracks and fractures of the outboard hinge fitting assemblies on the trailing edge of the inboard main flap, and follow-on and corrective actions if necessary; and, for certain airplanes, a one-time inspection to determine if a tool runout option has been performed in the area. The NPRM also reduced compliance times on certain airplanes (Model 767-400ER series airplanes), revised the applicability, and added an optional terminating action.

Actions Since Previous NPRM (77 FR 6685, February 9, 2012) Was Issued

Since we issued the NPRM (77 FR 6685, February 9, 2012), we have received reports of hinge assembly fractures found before the current inspection interval on Model 767-200, -300, and -300F series airplanes.

Comments

We gave the public the opportunity to comment on the NPRM (77 FR 6685, February 9, 2012). The following presents the comments received on the NPRM and the FAA's response to each comment.

Support for the NPRM (77 FR 6685, February 9, 2012)

An anonymous commenter supported the NPRM (77 FR 6685, February 9, 2012).

Request To Revise Applicability

American Airlines requested that we revise the applicability of the NPRM (77 FR 6685, February 9, 2012) to identify specific flap serial numbers instead of airplane line numbers. The commenter stated that a flap removed from the hinge assembly could then be installed on a different airplane.

We partially agree. We agree that the subject flaps are rotable parts that may be removed and reinstalled on different Start Printed Page 58295airplanes after compliance with the AD. We have therefore added new paragraph (q) in this SNPRM (and redesignated subsequent paragraphs) to prohibit installation of an inboard main flap unless it has been inspected and repaired in accordance with the requirements of this SNPRM. But we do not agree to change the applicability as requested because this AD action applies to the airplane, not a component.

Since the flight cycles on the flaps may not be tracked by some operators, we mandated a compliance time tied to the total flight cycles of the airplane. Operators may request approval of an alternative compliance time, however, if the actual accumulated flight cycles on reinstalled flaps are known.

Request To Specify Additional Airplanes Subject to Repetitive Inspection Requirement

Boeing noted that paragraph (n) of the NPRM (77 FR 6685, February 9, 2012) specifies repetitive detailed and/or eddy current inspections for Model 767-400ER series airplanes. Boeing requested that we revise paragraph (n) of the NPRM to add the following revised service information: Boeing Alert Service Bulletin 767-57A0076, Revision 3, dated April 4, 2012 (for Models 767-200, -300, and -300F airplanes); and Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 2012 (for Model 767-400ER series airplanes). Boeing noted that this revised service information improves crack detection by clarifying the HFEC inspection area, based on a recent finding of a crack located along the edge of the inspection area on a Model 767-300 series airplane. We infer that Boeing wants us to revise paragraph (n) of the NPRM to add Model 767-200, -300, and -300F series airplanes.

In addition, paragraph (o) of the NPRM (77 FR 6685, February 9, 2012) specifies a new optional terminating action. Boeing requested that we revise that paragraph to include terminating action for Model 767-200, -300, and -300F series airplanes (in addition to Model 767-400ER series airplanes), and to refer to Boeing Alert Service Bulletins 767-57A0076, Revision 3, dated April 4, 2012; and 767-57A0079, Revision 2, dated March 23, 2012.

Further, Boeing requested that we revise paragraph (p) of the NPRM (77 FR 6685, February 9, 2012) to provide credit for previous actions done using Boeing Service Bulletin 767-57A0076, Revision 2, dated November 22, 2006; and Boeing Service Bulletin 767-57A0079, Revision 1, dated May 6, 2010.

We agree with the requests, for the reasons provided by the commenter. We have revised paragraphs (n) and (o) in this SNPRM to add the referenced airplanes and service information. For information on the procedures and compliance times, see Boeing Alert Service Bulletin 767-57A0076, Revision 3, dated April 4, 2012; and 767-57A0079, Revision 2, dated March 23, 2012; at http://www.regulations.gov by searching for and locating Docket No. FAA-2012-0108.

We also have revised paragraph (p) of this SNPRM to provide credit for Boeing Service Bulletin 767-57A0076, Revision 2, dated November 22, 2006; and Boeing Service Bulletin 767-57A0079, Revision 1, dated May 6, 2010. We have determined that accomplishment of the actions specified in this revised service information before the effective date of the AD would provide an adequate level of safety.

Request for Approval of AMOCs

Boeing, American Airlines, and UPS requested that AMOCs previously approved for paragraph (i) of AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), be considered acceptable for compliance with the requirements of paragraphs (g), (h), and (i) of the NPRM (77 FR 6685, February 9, 2012).

We agree. We have determined that the referenced AMOCs would provide an adequate level of safety. We have included this provision in new paragraph (r)(4) of this SNPRM.

FAA's Determination

We are proposing this SNPRM because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Certain changes described above expand the scope of the NPRM (77 FR 6685, February 9, 2012). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM.

Proposed Requirements of This SNPRM

This SNPRM would require accomplishing the actions specified in Boeing Alert Service Bulletin 767-57A0076, Revision 3, dated April 4, 2012; and 767-57A0079, Revision 2, dated March 23, 2012.

Costs of Compliance

We estimate that this proposed AD affects 440 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Retained detailed inspections10 work-hours × $85 per hour = $850 per inspection cycle$0$850 per inspection cycle$374,000 per inspection cycle.
Retained detailed and eddy current inspections13 work-hours × $85 per hour = $1,105 per inspection cycle$0$1,105 per inspection cycle$486,200 per inspection cycle.

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

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 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 this 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),

(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.

As of the effective date of this AD, only Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 2012, may be used for the inspection.

(h) Retained Follow-On/Corrective Actions

This paragraph restates the requirements of paragraph (b) of AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), with revised service information. Following the initial inspections required by paragraph (g) of this AD, perform applicable follow-on and corrective actions at the times specified in Figure 1 of Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001 (for Model 767-200, -300, and -300F series airplanes); or Boeing Alert Service Bulletin 767-57A0079, dated June 20, 2002 (for Model 767-400ER series airplanes); until the initial inspection required by paragraph (n) of this AD is accomplished and repeat thereafter at the applicable times specified in paragraph (n) of this AD. Do the follow-on and corrective actions (including repetitive inspections and replacement of the fittings with new fittings) in accordance with Part 1 or Part 2 of Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001; or Boeing Service Bulletin 767-57A0076, Revision 3, dated April 4, 2012 (for Model 767-200, -300, and -300F series airplanes); or Boeing Alert Service Bulletin 767-57A0079, dated June 20, 2002, or Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 2012 (for Model 767-400ER series airplanes); except as required by paragraph (i)(2) of this AD. For Model 767-200, -300, and -300F series airplanes: If the fitting has the tool runout, and no cracking or fracture is found during the inspection, this AD requires no further action for that hinge fitting. As of the effective date of this AD, for the actions required by this paragraph, only Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 2012, may be used for Model 767-400ER series airplanes; and only Boeing Alert Service Bulletin 767-57A0076, Start Printed Page 58297Revision 3, dated April 4, 2012, may be used for Model 767-200, -300, and -300F airplanes.

(i) Retained Exceptions to Service Bulletin Procedures

This paragraph restates the requirements of paragraph (c) of AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003). The following exceptions specified in paragraphs (i)(1) and (i)(2) of this AD apply.

(1) Where the terminating action in Part 3 of Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001; and Revision 3, dated April 4, 2012; and Boeing Alert Service Bulletin 767-57A0079, dated June 20, 2002; Revision 1, dated May 6, 2010; and Revision 2, dated March 23, 2012; as applicable; is specified as corrective action, this AD requires that the terminating action, if required, be accomplished before further flight.

(2) Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001; and Revision 3, dated April 4, 2012; specify to contact Boeing before the terminating action is done as corrective action for any cracking or fracture found on a Model 767-200, -300, or -300F series airplane with the tool runout. However, this AD requires that any such crack or fracture on those airplanes be repaired in accordance with Part 3 of Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001; or Revision 3, dated April 4, 2012. This AD does not require a report.
