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

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes Airworthiness Directive (AD) 2001-
20-14, which currently requires you to replace the brake shuttle valves 
with parts of improved design and install a shield over the hydraulic 
lines on certain Fairchild Aircraft SA226 and SA227 series airplanes. 
AD 2001-20-14 also requires you to replace the rubber fuel hose with a 
metal device for certain SA226 series airplanes. This AD is the result 
of FAA incorrectly referencing Model SA226--T(A) airplanes and 
inadvertently omitting certain serial numbers of Model SA227--AC 
airplanes from the applicability of AD 2001-20-14. This AD retains the 
actions of AD 2001-20-14, corrects the reference of Model SA226--T(A) 
airplanes and adds additional Model SA227--AC airplanes to the 
applicability section of the AD. The actions specified by this AD are 
intended to correct potential brake shuttle valve problems, which could 
cause the brake assembly to drag and overheat. Hydraulic or fuel line 
damage could then occur if the overheated brake assembly is retracted 
into the main wheel well with a consequent fire if the hydraulic or 
fuel lines ruptured.

DATES: This AD becomes effective on June 6, 2002.
    The Director of the Federal Register previously approved the 
incorporation by reference of certain publications listed in the 
regulations as of November 21, 2001 (66 FR 52020, October 12, 2001).

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA received a report of an accident involving a Fairchild 
Model SA226--TC airplane where the flight crew lost control of the 
airplane at low altitude during the final approach for landing. Prior 
to the accident, the flight crew reported a loss of hydraulic pressure 
and a fire on the left side of the airplane. The report of this 
accident caused us to issue AD 2001-20-14, Amendment 39-12462 (66 FR 
52020, October 12, 2001). This AD requires the following on certain 
Fairchild Aircraft SA226 and SA227 series airplanes:

--Replace the brake shuttle valves with parts of improved design 
(except on airplanes with an anti-skid/power brake system);
--Install a shield over the hydraulic lines; and
--Replace the rubber fuel hose with a metal device on certain SA226 
series airplanes.

What Has Happened Since AD 2001-20-14 To Initiate This Action?

    The FAA incorrectly referenced Model SA226--T(A) airplanes and 
inadvertently omitted certain serial numbers of Model SA227--AC 
airplanes from the applicability of AD 2001-20-14. In particular, we 
referenced serial numbers T(A)249 through T(A)291 as Model SA226--T(A) 
airplanes. These serial numbers should be T249 through T291, except 
T276, as Model SA226--T airplanes. We also restricted the applicability 
of Model SA227--AC airplanes to serial numbers AC406, AC415, AC416, and 
AC420 through AC599. Any Model SA227--AC airplane incorporating a 
serial number from AC600 through AC789 should also be affected by the 
actions of AD 2001-20-14.

What Is the Potential Impact if FAA Took No Action?

    Original design brake shuttle valves, if not replaced with improved 
design valves, could cause the wheel brakes to drag and overheat. This 
could result in hydraulic or fuel line damage if the overheated brake 
assembly is retracted into the main wheel wells. A consequent fire 
could occur if the hydraulic or fuel lines ruptured.

Has FAA Taken Any Action to This Point?

    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 
certain Fairchild Aircraft SA226 and SA227 series airplanes. This 
proposal was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on December 27, 2001 (66 FR 66828). The NPRM proposed 
to supersede AD 2001-20-14 with a new AD that would retain the actions 
of AD 2001-20-14, would correct the reference to Model SA226--T(A) 
airplanes, and would include additional Model SA227--AC airplanes in 
the Applicability section of the AD.

Was the Public Invited To Comment?

    The FAA encouraged interested persons to participate in the making 
of this amendment. We did not receive any comments on the proposed rule 
or on our determination of the cost to the public.

FAA's Determination

What Is FAA's Final Determination on This Issue?

    After careful review of all available information related to the 
subject presented above, we have determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. We have determined that these minor 
corrections:

--Provide the intent that was proposed in the NPRM for correcting the 
unsafe condition; and
--Do not add any additional burden upon the public than was already 
proposed in the NPRM.

Cost Impact

How Many Airplanes Does This AD Impact?

    We estimate that this AD affects 186 SA226 Series airplanes and 72 
SA227 Series airplanes in the U.S. registry for total of 258 affected 
airplanes.

What Is the Cost Impact of This AD on Owners/Operators of the Affected 
Airplanes?

    We estimate the following costs to accomplish the replacement and 
installation:

 $3,300.
----------------------------------------------------------------------------------------------------------------

    The only difference between AD 2001-20-14 and this AD is the 
expanded applicability of Model SA227-AC airplanes that we 
inadvertently omitted from the ``Applicability'' section of AD 2001-20-
14. However, the estimated number of total airplanes affected has not 
changed. The only impact this AD will have over that already required 
by AD 2001-20-14 is the burden to the owners/operators of the cost of 
the actions on the additional airplanes.

Compliance Time of This AD

What Will Be the Compliance Time of This AD?

    The compliance time of this AD is at whichever of the following 
that occurs later:

--Within 500 hours time-in-service (TIS) after the effective date of 
this AD or AD 2001-20-14, as applicable; or
--Within 6 months after the effective date of this AD or AD 2001-20-14, 
as applicable.

Why Is the Compliance Time of This AD Presented in Both Hours TIS and 
Calendar Time?

    The affected airplanes are used in both general aviation and 
commuter operations. Those commuter operators may accumulate 500 hours 
TIS on the airplane in less than 2 months and many owners have numerous 
affected airplanes in their fleets. We have determined that the dual 
compliance time:

--Gives all owners/operators of the affected airplanes adequate time to 
schedule and accomplish the actions in this AD; and
--assures that the unsafe condition referenced in this AD will be 
corrected within a reasonable time period without inadvertently 
grounding any of the affected airplanes.

Regulatory Impact

Does This AD Impact Various Entities?

    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.

Does This AD Involve a Significant Rule or Regulatory Action?

    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.
