Airworthiness Directives; Fairchild Aircraft, Inc. SA226 and 
SA227 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment supersedes Airworthiness Directive (AD) 97-23-
01, which currently requires the following on Fairchild Aircraft, Inc. 
(Fairchild Aircraft) SA226 and SA227 series airplanes that are equipped 
with a certain Simmonds-Precision pitch trim actuator or a certain 
Barber-Colman pitch trim actuator: repetitively measuring the freeplay 
of the pitch trim actuator and repetitively inspecting the actuator for 
rod slippage; immediately replacing any actuator if certain freeplay 
limitations are exceeded or rod slippage is evident; and eventually 
replacing the actuator regardless of the inspection results. This AD 
retains the actions of AD 97-23-01, and adds these requirements on 
airplanes with different design pitch trim actuators installed. This AD 
is the result of the manufacturer developing different design pitch 
trim actuators and the Federal Aviation Administration (FAA) 
determining that these actuators should be subject to the actions of AD 
97-23-01. The actions specified by this AD are intended to detect 
excessive freeplay or rod slippage in the pitch trim actuator, which, 
if not detected and corrected, could result in pitch trim actuator 
failure and possible loss of control of the airplane.

DATES: Effective April 10, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of April 10, 2000.

ADDRESSES: Service information that applies to this AD may be obtained

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This AD

    A proposal to amend part 39 of the Federal Aviation Regulations (14 
CFR part 39) to include an AD that would apply to Fairchild Aircraft 
SA226 and SA227 series airplanes that are equipped with a certain 
Simmonds-Precision pitch trim actuator or Barber-Colman pitch trim 
actuator was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on October 6, 1999 (64 FR 54242). The NPRM proposed 
to supersede AD 97-23-01, Amendment 39-10188 (62 FR 59277, November 3, 
1997). AD 97-23-01 currently requires the following on Fairchild 
Aircraft SA226 and SA227 series airplanes that are equipped with a 
certain Simmonds-Precision pitch trim actuator:

--repetitively measuring the freeplay of the pitch trim actuator and 
repetitively inspecting the actuator for rod slippage;
--immediately replacing any actuator if certain freeplay limitations 
are exceeded or rod slippage is evident; and
--eventually replacing the actuator regardless of the inspection 
results.

    In addition, AD 98-19-15 R1, Amendment 39-11507 (65 FR 1540, 
January 11, 2000), currently requires incorporating the following 
information into the applicable Airplane Flight Manual (AFM) on 
Fairchild SA226 and SA227 airplanes that are equipped with Barber-
Colman pitch trim actuators, P/N 27-19008-001/-004 or P/N 27-19008-002/
-005 (these pitch trim actuators are affected by AD 97-23-01):
    <bullet> ``Limit the maximum indicated airspeed to maneuvering 
airspeed (Va) as shown in the appropriate airplane flight manual 
(AFM).''
and
    <bullet> ``The minimum crew required is two pilots.''
    The NPRM proposed to retain the requirements of AD 97-23-01, but 
would add these requirements on airplanes with the improved design 
pitch trim actuators installed.
    The NPRM was the result of the manufacturer developing different 
design pitch trim actuators and the Federal Aviation Administration 
(FAA) determining that these actuators should be subject to the actions 
of AD 97-23-01.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.

The FAA's Determination

    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. The FAA has determined that these minor 
corrections will not change the meaning of the AD and will not add any 
additional burden upon the public than was already proposed.

Cost Impact

    The FAA estimates that 508 airplanes in the U.S. registry will be 
affected by this AD. The only cost impact that this AD imposes upon the 
public over that already required by AD 97-23-01 is that incurred 
through the addition of the requirements on airplanes with the improved 
design pitch trim actuators installed. The costs of this AD on those 
airplanes that have these improved design pitch trim actuators 
incorporated will be less than that already required by AD 97-23-01 on 
airplanes with other pitch trim actuators installed.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and (3) 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. A copy of the final evaluation prepared for this 
action is contained in the Rules Docket. A copy of it may be obtained 
by contacting the Rules Docket at the location provided under the 
caption ADDRESSES.
