**[Docket No. FAA–2013–0460; Directorate Identifier 2012–NM–222–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes** 

**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 all Saab AB, Saab Aerosystems Model 340B airplanes. The NPRM proposed to require an inspection of the stick pusher rigging and an adjustment to the correct setting if necessary. The NPRM was prompted by a report that the elevator position quoted in an aircraft maintenance manual is incorrect and a report that the trunnion at the lower part of the control column was installed incorrectly. This action revises the NPRM by proposing to require an inspection of the installation of the trunnion and the stick pusher rigging, and corrective actions if necessary. We are proposing this AD to correct the rigging of the elevator position of the stick pusher to reduce the probability of a negative effect on the handling quality during stall, which could result in reduced controllability of the airplane. Since these actions impose an additional burden over that proposed in the NPRM and at the request of a commenter, 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 proposed AD by September 26,
2014.

Discussion

We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to all Saab AB, Saab Aerosystems Model 340B airplanes. The NPRM published in the Federal Register on June 3, 2013 (78 FR 33010). The NPRM proposed to require actions intended to correct the rigging of the elevator position of the stick pusher to reduce the probability of a negative effect on the handling quality during stall, which could result in reduced controllability of the airplane.
Actions Since Previous NPRM (78 FR 33010, June 3, 2013) Was Issued

Since we issued the NPRM (78 FR 33010, June 3, 2013), it has been reported that on some airplanes, during implementation of Saab Service Bulletin 340–27–105, Revision 01, dated August 31, 2012, the trunnion at the lower part of the control column was installed incorrectly, which prevented proper inspection of the stick pusher rigging.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0253, dated October 18, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI
states:

The standard stick pusher maximum elevator position of a SAAB 340B, prior to delivery, is set at 7.5 degrees trailing edge down. It was recently discovered that this value has been incorrectly referenced in the SAAB 340B Aircraft Maintenance Manual (AMM), which quotes an elevator position of 4 degrees trailing edge down for all aeroplanes, which is the correct value for SAAB SF340A aeroplanes only.


### 47026 Federal Register / Vol. 79, No. 155 / Tuesday, August 12, 2014 / Proposed Rules

If a SAAB 340B aeroplane has been rerigged in accordance with current AMM procedure, there is a possibility that the deflection of the elevator will be less than intended.

This condition, if not corrected, will affect the stall characteristics on the outer part of the envelope at maximum flap setting and aft centre of gravity (CG) configuration, possibly resulting in reduced control of the aeroplane.

To address this potential unsafe condition, SAAB AB Aeronautics issued Service Bulletin (SB) 340–27–105 to reduce the probability of a negative effect on the handling quality during stall. Consequently, EASA issued AD 2012–0256 [http:// www.regulations.gov/ #!documentDetail;D=FAA-2013-0460-0002] to require a one-time inspection of the stick pusher rigging and, depending on findings, adjustment to the correct setting.

Since that [EASA] AD was issued, it has been reported that on some aeroplanes, during implementation of SB 340–27–105, the trunnion at the lower part of the control column was incorrectly installed. This prevents proper inspection of the stick pusher rigging.

Prompted by this finding, SAAB issued SB 340–27–115 with instructions for all aeroplanes, regardless whether SB 340–27– 105 has been accomplished or not.

For the reasons described above, this AD retains the requirements of EASA AD 2012– 0256, which is superseded, but requires the use of the improved and expanded instructions specified in SAAB SB 340–27–

115.

The required actions include a detailed inspection of the installation of the trunnion at the lower part of the control column and the stick pusher rigging, and corrective actions if necessary. Corrective actions include adjusting to the correct setting, and repair. 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–2013–
0460.

Relevant Service Information

Saab AB, Saab Aerosystems has issued Service Bulletin 340–27–115, dated July 19, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

Comments

We gave the public the opportunity to comment on the NPRM (78 FR 33010, June 3, 2013). The following presents the comment received on the NPRM and the FAA’s response to each comment. Request To Delay Issuance of AD

Saab AB, Saab Aerosystems (Saab) requested that the issuance of the final rule be delayed until new service information is introduced.

As stated previously, Saab Service Bulletin 340–27–115, dated July 19, 2013, has been issued, which supersedes Saab Service Bulletin 340– 27–114, dated July 8, 2013; and Saab Service Bulletin 340–27–105, Revision 01, dated August 31, 2012. We have revised paragraphs (g) and (h) of this SNPRM to refer to Saab Service Bulletin 340–27–115, dated July 19, 2013, as the appropriate source of service information for the proposed requirements. FAA’s Determination and Requirements of This SNPRM

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 the same type design.

Certain changes described above expand the scope of the NPRM (78 FR 33010, June 3, 2013). 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. ‘‘Contacting the Manufacturer’’ Paragraph in This SNPRM

Since late 2006, we have included a standard paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD.

The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/ operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved.

In an NPRM having Directorate Identifier 2012–NM–101–AD (78 FR 78285, December 26, 2013), we proposed to prevent the use of repairs that were not specifically developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to the FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase ‘‘its delegated agent’’ to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD.

One commenter to the NPRM having Directorate Identifier 2012–NM–101–AD (78 FR 78285, December 26, 2013) stated the following: ‘‘The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.’’

This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19.

To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it ‘‘Contacting the Manufacturer.’’ This paragraph now clarifies that for any requirement in this SNPRM to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, the European Aviation Safety Agency (EASA), or Saab AB, Saab Aerosystems’ EASA DOA.

The Contacting the Manufacturer paragraph also clarifies that, if approved by the DOA, the approval must include the DOA-authorized signature. The DOA signature indicates that the data and information contained in the documentare EASA-approved, which is also FAAapproved. Messages and other information provided by the manufacturer that do not contain the DOA-authorized signature approval are not EASA-approved, unless EASA


### 47027 Federal Register / Vol. 79, No. 155 / Tuesday, August 12, 2014 / Proposed Rules

directly approves the manufacturer’s message or other information.

This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers’ service instructions that are ‘‘Required for Compliance’’ with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance.

We also have decided not to include a generic reference to either the ‘‘delegated agent’’ or ‘‘design approval holder (DAH) with State of Design Authority design organization approval,’’ but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH throughout this SNPRM. Costs of Compliance

We estimate that this SNPRM affects 109 airplanes of U.S. registry.

We estimate that it would take about 12 work-hours per product to comply with the basic requirements of this SNPRM. The average labor rate is $85 per work-hour. Required parts would cost about $10 per product. Based on these figures, we estimate the cost of this SNPRM on U.S. operators to be $112,270, or $1,030 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 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 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

**RIN 2120–AA64**

**Airworthiness Directives; Airbus Airplanes** 

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

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a determination that the maintenance actions for airplane systems susceptible to aging must be mandated. This proposed AD would require revising the maintenance or inspection program to incorporate more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to mitigate the risks associated with aging effects of airplane systems. Such aging effects could change the characteristics leading to an increased potential for failure, which could result in failure of certain life limited parts, and could reduce the structural integrity or reduce controllability of the airplane.

**DATES :**  We must receive comments on this proposed AD by September 26,
2014.

**ADDRESSES :**  You may send comments by any of the following methods:
