Federal Register Abstract
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.

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 [<a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;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 <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;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:
<bullet> Are consistent with the intent that was proposed in the
SNPRM (79 FR 47025, August 12, 2014) for correcting the unsafe
condition; and
<bullet> 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.
[[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.
