# AGENCY:

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

# ACTION:

Final rule.

# SUMMARY:

We are adopting a new airworthiness directive (AD) for all Saab AB, Saab Aerosystems Model 340B airplanes. This AD 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 AD requires an inspection of the stick pusher rigging and an inspection of the installation of the trunnion and the stick pusher rigging, and corrective actions if necessary. We are issuing 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.

# DATES:

This AD becomes effective February 9, 2015.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 9, 2015.

# SUPPLEMENTARY INFORMATION:

## Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Saab AB, Saab Aerosystems Model 340B airplanes. The SNPRM published in the **Federal Register** on August 12, 2014 (79 FR 47025). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the **Federal Register** on June 3, 2013 (78 FR 33010).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, 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 on all Saab AB, Saab Aerosystems Model 340B airplanes. 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.

If a SAAB 340B aeroplane has been re-rigged 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 [EASA] 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.

You may examine the MCAI in the AD docket on the Internet at *http://www.regulations.gov/​#!documentDetail;​D=​FAA-2013-0460-0005*.

## Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (79 FR 47025, August 12, 2014) or on the determination of the cost to the public.

## Conclusion

We reviewed the relevant data 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 SNPRM ( 79 FR 47025 , August 12, 2014) for correcting the unsafe condition; and
    - Do not add any additional burden upon the public than was already proposed in the SNPRM ( 79 FR 47025 , August 12, 2014).

## Costs of Compliance

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

We also estimate that it will take about 12 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $10 per product. Based on these figures, we estimate the cost of this AD 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 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.       ( print page 154)    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 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 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.
