Airworthiness Directives; M7 Aerospace LP SA226 and SA227 Series 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) to 
supersede AD 98-19-15 R1 and AD 2000-03-17, which apply to M7 Aerospace 
LP SA226 and SA227 series airplanes equipped with certain pitch trim 
actuators. AD 98-19-15 R1 currently requires you to incorporate changes 
into the Limitations Section of the FAA-approved airplane flight manual 
(AFM) if certain part number (P/N) pitch trim actuators are installed. 
AD 2000-03-17 requires repetitive inspections and repetitive 
replacements of the pitch trim actuator. The repetitive inspection and 
repetitive replacement times vary depending on the combination of 
airplane model and pitch trim actuator P/N installed. Since we issued 
AD 98-19-15 R1 and AD 2000-03-17, we have determined that reliance on 
critical repetitive inspections on aging commuter-class airplanes 
carries an unnecessary safety risk when a design change exists that 
could eliminate or, in certain instances, reduce the number of those 
critical inspections. Consequently, this AD retains all of the actions 
of the previously referenced ADs, places life limits on certain P/N 
pitch trim actuators, and requires the replacement of certain P/N pitch 
trim actuators with one of an improved design. Once installed, the 
improved design pitch trim actuator will terminate the AFM limitations 
in this AD and reduce the repetitive inspection and repetitive 
replacement requirements. We are issuing this AD 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. We 
are also issuing this AD to lessen the severity of pitch upset if a 
pitch trim actuator mechanical failure occurs. These conditions could 
lead to possible loss of control.

DATES: This AD becomes effective on September 7, 2007.

SUPPLEMENTARY INFORMATION: 

Discussion

    On April 20, 2007, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to M7 Aerospace LP SA226 and SA227 series airplanes 
equipped with certain pitch trim actuators. This proposal was published 
in the Federal Register as a notice of proposed rulemaking (NPRM) on 
April 30, 2007 (72 FR 21171). The NPRM proposed to supersede AD 98-19-
15 R1 and AD 2000-03-17 with a new AD that would retain all of the 
actions of the previously referenced ADs but limit the part numbers of 
the pitch trim actuators that can be used for replacement. The NPRM 
also proposed placing a life limit on Barber-Coleman pitch trim 
actuators P/N 27-19008-001, P/N 27-19008-002, P/N 27-19008-004, and P/N 
27-19008-005. The NPRM proposed to require you to use the service 
information described previously to perform these actions.

Comments

    We provided the public the opportunity to participate in developing 
this AD. We received no comments on the proposal or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 307 airplanes in the U.S. 
registry.
    This AD requires pitch trim actuators to have a combination of 
inspections, overhaul, and/or replacement. We have presented the fleet 
cost as the lowest cost based on all airplanes needing the inspection 
and the highest cost based on all airplanes needing the overhaul. The 
actual fleet cost will be somewhere between the lowest and highest 
fleet cost presented. We have no way of determining the number of 
airplanes needing replacement. (See below for airplane replacement 
cost.)
    We estimate the following costs to do the inspection or overhaul:

----------------------------------------------------------------------------------------------------------------
                                                                                  Total cost per   Total cost on
                 Labor cost                               Parts cost                 airplane     U.S. operators
----------------------------------------------------------------------------------------------------------------
For inspection: 4 work-hours x $80 per hour  None...............................            $320         $98,240
 = $320.
For overhaul: 4 work-hours x $80 per hour =  $9,000.............................           9,320       2,861,240
 $320.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that are required through the actions of this AD. We have no way of 
determining the number of airplanes that may need this replacement:

------------------------------------------------------------------------
                                                             Total cost
                 Labor cost                    Parts cost   per airplane
------------------------------------------------------------------------
4 work-hours x $80 per hour = $320..........      $64,000       $64,320
------------------------------------------------------------------------

    The replacement estimate is based on replacing the pitch trim 
actuator with a new Simmonds-Precision P/N DL5040M8 pitch trim 
actuator. If the pitch trim actuator is replaced with a different P/N 
FAA-approved pitch trim actuator or a zero-timed FAA-approved pitch 
trim actuator the cost to the owner/operator could be less.
    The estimated costs represented in the above actions include the 
costs associated with AD 98-19-15 R1, AD 2000-03-17, and the costs of 
this AD. The added cost impact this AD imposes upon an owner/operator 
over that already required by AD 98-19-15 R1 and AD 2000-03-17 is the 
eventual replacement of the pitch trim actuator if the airplane 
currently has installed a Barber-Coleman pitch trim actuator P/N 27-
19008-001, P/N 27-19008-002, P/N 27-19008-004, or P/N 27-19008-005.

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 AD.

Regulatory Findings

    We have 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;

[[Page 43141]]

    2. Is not a ``significant rule'' under the 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.
    We prepared a summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2006-25927; Directorate Identifier 2006-CE-52-AD'' in your 
request.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
98-19-15 R1, Amendment 39-11507 (65 FR 1540, January 11, 2000), and AD 
2000-03-17, Amendment 39-11576 (65 FR 8037, February 17, 2000); and by 
adding the following new AD:

2007-16-03 M7 Aerospace LP (Type Certificate No. A5SW, A8SW, and 
A18SW formerly held by Fairchild Aircraft Incorporated): Amendment 
39-15142; Docket No. FAA-2006-25927; Directorate Identifier 2007-CE-
52-AD.

Effective Date

    (a) This AD becomes effective on September 7, 2007.

Affected ADs

    (b) This AD supersedes the following ADs:
    (1) AD 98-19-15 R1, Amendment 39-11507; and
    (2) AD 2000-03-17, Amendment 39-11576.

Applicability

    (c) This AD applies to all Models SA226-AT, SA226-T, SA226-T(B), 
SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, 
SA227-DC (C-26B), SA227-PC, and SA227-TT airplanes, all serial 
numbers, that:
    (1) are certificated in any category; and
    (2) are equipped with pitch trim actuator Barber-Coleman part 
number (P/N) 27-19008-001, Barber-Coleman P/N 27-19008-002, Barber-
Coleman P/N 27-19008-004, Barber-Coleman P/N 27-19008-005, Barber-
Coleman P/N 27-19008-006, Barber-Coleman P/N 27-19008-007, Simmonds-
Precision P/N DL5040M5, Simmonds-Precision P/N DL5040M6, or 
Simmonds-Precision P/N DL5040M8.

Unsafe Condition

    (d) This AD results from reports of mechanical failure of the 
pitch trim actuator causing the horizontal stabilizer to move to 
full aircraft nose up. We are issuing this AD 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. 
We are also issuing to lessen the severity of pitch upset if a pitch 
trim actuator mechanical failure occurs. These conditions could lead 
to possible loss of control. In addition, we are issuing to 
eliminate the use of certain pitch trim actuators that require 
frequent critical inspections or replacements.

Compliance

    (e) To address this problem, you must do the following, unless 
already done:
    (1) For airplanes with a Barber-Coleman pitch trim actuator P/N 
27-19008-001, P/N 27-19008-002, P/N 27-19008-004, or P/N 27-19008-
005: Before further flight after September 25, 1998 (the effective 
date of AD 98-19-15), incorporate the text in paragraphs (e)(1)(i) 
and (e)(1)(ii) of this AD into the Limitations Section of the FAA-
approved airplane flight manual (AFM). The owner/operator holding at 
least a private pilot certificate as authorized by section 43.7 of 
the Federal Aviation Regulations (14 CFR 43.7) may insert the 
information specified in paragraphs (e)(1)(i) and (e)(1)(ii) of this 
AD into the AFM Limitations Section. This may be done by inserting a 
copy of this AD into the AFM. Make an entry into the aircraft 
records showing compliance with this portion of the AD in accordance 
with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
    (i) ``Limit the maximum indicated airspeed to maneuvering 
airspeed (Va) as shown in the appropriate airplane flight manual 
(AFM)''; and
    (ii) ``The minimum crew required is two pilots.''

    Note 1: Fairchild Service Letter 226-SL-017, Fairchild Service 
Letter 227-SL-033, and Fairchild Service Letter CC7-SL-023, all FAA 
Approved: August 26, 1998; Revised: September 2, 1998, address the 
subject matter of this AD.


    Note 2: The before further flight compliance time of paragraph 
(e)(1) of this AD is retained from AD 98-19-15 R1.


    Note 3: Installation of any FAA-approved pitch trim actuator 
other than the Barber-Coleman P/N 27-19008-001, P/N 27-19008-002, P/
N 27-19008-004, or P/N 27-19008-005 terminates the requirements of 
paragraph (e)(1) of this AD.

    (2) For all airplanes: Do the following actions at the times 
specified in the initial inspection or overhaul column and the 
repetitive inspection or overhaul column in table 1 of this AD:
    (i) For airplanes equipped with a Simmonds-Precision pitch trim 
actuator P/N DL5040M5, P/N DL5040M6, or P/N DL5040M8: Measure the 
freeplay of the pitch trim actuator and inspect the pitch trim 
actuator for rod slippage using the INSTRUCTIONS section of 
Fairchild Aircraft SA226 Series Service Letter (SL) 226-SL-005 or 
Fairchild Aircraft SA227 Series SL 227-SL-011, both Revised: August 
3, 1999; or Fairchild Aircraft SA227 Series Service Letter CC7-SL-
028, Issued: August 12, 1999, as applicable.
    (ii) For airplanes equipped with Barber-Colman pitch trim 
actuators P/N 27-19008-001, P/N 27-19008-002, P/N 27-19008-004, or

actuator using the INSTRUCTIONS section of Fairchild Aircraft SA226 
Series SL 226-SL-014, Fairchild Aircraft SA227 Series SL 227-SL-031, 
or Fairchild Aircraft SA227 Series SL CC7-SL-021; all Revised: 
February 1, 1999; as applicable.

    Note 4: The actions in paragraphs (e)(2)(i) and (e)(2)(ii) of 
this AD are the same as the actions in AD 2000-03-17. The only 
difference between this AD and AD 2000-03-17 is the addition of life 
limits to Barber-Coleman pitch trim actuators P/N 27-19008-001, P/N 
27-19008-002, P/N 27-19008-004, or P/N 27-19008-005.

    (iii) For airplanes equipped with Barber-Colman pitch trim 
actuators P/N 27-19008-006 or P/N 27-19008-007: Overhaul the pitch 
trim actuator following the applicable maintenance manual.
    (3) For all airplanes: Before further flight, replace the pitch 
trim actuator following the applicable maintenance manual when any 
of the following occurs:
    (i) The pitch trim actuator is inspected following paragraphs 
(e)(2)(i) and (e)(2)(ii) of this AD and the freeplay limitations are 
exceeded, rod slippage is found, or a ratcheting sound occurs, as 
specified in the applicable service letters; or
    (ii) The installed pitch trim actuator reaches its repetitive 
replacement time as specified in table 1 in paragraph (e)(4) of this 
AD.
    (4) Table 1 below presents the pitch trim actuators that could 
be installed and the compliance times for the initial inspections or 
overhaul, repetitive inspections or overhaul, and repetitive 
replacements required by this AD:
