List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

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

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 

### 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):

Airbus: Docket No. FAA–2015–3990; Directorate Identifier 2014–NM–255–AD.

(a) Comments Due Date

We must receive comments by December 3,
2015.
(b) Affected ADs

None. (c) Applicability

This AD applies to Airbus Model A320– 214, –232, and –233 airplanes; and Airbus Model A321–211 and –231 airplanes, certificated in any category, having manufacturer serial numbers (MSNs) 5583, 5598, 5602, 5604, 5608, 5610, 5613 through 5622 inclusive, 5624 through 5627 inclusive, 5629 through 5632 inclusive, 5634 through 5636 inclusive, 5638, 5640 through 5644 inclusive, 5646 through 5649 inclusive, 5651 through 5653 inclusive, 5655, 5657 through 5661 inclusive, 5663, 5665, 5667, 5670, 5672, 5673, and 5675.
(d) Subject

Air Transport Association (ATA) of America Code 25, Equipment/Furnishings.

(e) Reason

This AD was prompted by reports of incorrect installation of jiffy joint connectors on cables connected to certain passenger service units (PSU), which could cause the passenger oxygen container to malfunction if the connector becomes disengaged during flight due to vibration. We are issuing this AD to prevent failure of the door of the passenger oxygen container to open in the event of airplane decompression, resulting in lack of oxygen supply and consequent injury to occupants. (f) Compliance

Comply with this AD within the compliance times specified, unless already done.
(g) Inspection and Related Investigative and Corrective Actions

Within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first, do an inspection to identify the part number and serial number of each PSU and if an affected part number or serial number is found, do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320– 25–1B20, dated October 9, 2014. Do all applicable related investigative and corrective actions within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first. An affected PSU part number or serial number is one listed in Appendix 1 of Airbus Operations GmbH Vendor Service Bulletin Z315H–25–004, dated September 26, 2014. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and serial number of the PSU can be conclusively determined from that review.

(h) Clarification of Vendor Service Information

Appendix 1 of Airbus Operations GmbH Vendor Service Bulletin Z315H–25–004, dated September 26, 2014, identifies Attachment 1 as the list of affected PSU part numbers and serial numbers. Also, the ‘‘List of Attachments’’ in Appendix 1, specifies Attachment 1 as Table 4, however ‘‘Attachment 1’’ and ‘‘Table 4’’ do not appear on any of the pages of the list of affected PSU part numbers and serial numbers, nor does a date. Furthermore, the pagination of the list of affected PSU part numbers and serial numbers is independent of the pagination of Airbus Operations GmbH Vendor Service Bulletin Z315H–25–004, dated September 26,
2014.
(i) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2015–0117, dated June 24, 2015; corrected August 7, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318; A319; A320; and A321 series airplanes. The MCAI states:

Reports have been received indicating premature ageing of certain chemical oxygen generators, Part Number (P/N) 117042–XX (XX representing any numerical value), manufactured by B/E Aerospace. Some operators reported that when they tried to activate generators, some older units failed to activate. Given the number of failed units reported, all generators manufactured in 1999, 2000 and 2001 were considered unreliable.

This condition, if not corrected, could lead to failure of the generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to aeroplane occupants.

To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A35N006–14, making reference to B/ E Aerospace Service Information Letter (SIL) D1019–01 (currently at Revision 1) and B/E Aerospace Service Bulletin (SB) 117042–35–
001.

Consequently, EASA issued AD * * * (later revised) to require identification and replacement of the affected oxygen generators.

Since EASA AD 2014–0275R1 [ http:// ad.easa.europa.eu/ad/2014-0275R1 ] was issued, and following new investigation results, EASA have decided to introduce a life limitation concerning all P/N 117042–XX chemical oxygen generators, manufactured by B/E Aerospace.

For the reason described above, this [EASA] AD retains the requirements of the EASA AD 2014–0275R1, which is superseded, expands the scope of the [EASA] AD to include chemical oxygen generators manufactured after 2001, and requires their removal from service before exceeding 10 years since date of manufacture.



### You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015–
3989.

Related Service Information Under 1 CFR Part 51

Airbus has issued Alert AOT A35N006–14, dated December 10, 2014, including Appendix 01.

B/E Aerospace Inc. has issued Service Bulletin 117042–35–001, dated December 10, 2014.

This service information describes procedures to replace certain passenger chemical oxygen generators. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** 

### section of this NPRM. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs.


## 63138 Federal Register / Vol. 80, No. 201 / Monday, October 19, 2015 / Proposed Rules

Costs of Compliance

We estimate that this proposed AD affects 953 airplanes of U.S. registry.

We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $390 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $533,680, or $560 per product. Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with, a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this proposed AD is 2120– 0056. The paperwork cost associated with this proposed AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this proposed AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES–200. 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. List of Subjects in 14 CFR Part 39

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Notice of proposed rulemaking (NPRM).

**SUMMARY** 

### : We propose to supersede Airworthiness Directive (AD) 2014–17– 51, for certain Bombardier, Inc. Model CL–600–2B16 airplanes. AD 2014–17– 51 currently requires inspecting the inboard flap fasteners of the hinge-box forward fitting at Wing Station (WS) 76.50 and WS 127.25 to determine the orientation and condition of the fasteners, as applicable, and replacement or repetitive inspections of the fasteners if necessary. AD 2014–17– 51 also provides for optional terminating action for the requirements of that AD. Since we issued AD 2014– 17–51, we have determined that additional action is necessary. This proposed AD would also require accomplishment of the previously optional terminating action. We are proposing this AD to detect and correct incorrectly oriented or fractured fasteners, which could result in premature failure of the fasteners attaching the inboard flap hinge-box forward fitting; failure of the fasteners could lead to the detachment of the flap hinge box and the flap surface, and consequent loss of control of the airplane.

**DATES** 

### : We must receive comments on this proposed AD by December 3, 2015.
