Airworthiness Directives; Saab AB, Saab Aerosystems 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 
Saab AB, Saab Aerosystems Model 340B airplanes. This proposed AD was 
prompted by a report that the elevator position quoted in an aircraft 
maintenance manual is incorrect for Saab 340B airplane. This proposed 
AD would require an inspection of the stick pusher rigging and an 
adjustment to the correct setting 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.

DATES: We must receive comments on this proposed AD by July 18, 2013.

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

Discussion

    The European Aviation Safety Agency (EASA), which is the aviation 
authority for the Member States of the European Community, has issued 
EASA Airworthiness Directive 2012-0256, dated December 3, 2012 
(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.
    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.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the stick pusher rigging and, depending on 
findings, adjustment to the correct setting.

The reference in the aircraft maintenance manual (AMM) for setting the 
maximum elevator position of the stick pusher of SAAB 340B model was 
corrected in December 2012 to show the correct value of 7.5 degrees 
trailing edge down. The revised AMM showing the correct value was 
provided to the operators of Saab 340B Model airplanes by the 
manufacturer. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Saab has issued Service Bulletin 340-27-105, Revision 01, dated 
August 31, 2012. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

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

[[Page 33011]]

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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 109 products of U.S. registry. We also estimate that 
it would take about 12 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 $10 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these parts. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $112,270, or $1,030 per product.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
