DEPARTMENT OF TRANSPORTATION
14 CFR Part 39

[Docket No. 93-CE-03-AD]


Airworthiness Directives; Fairchild Aircraft SA26, SA226, and 
SA227 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This document withdraws a notice of proposed rulemaking (NPRM) 
that would have revised AD 93-19-06, which requires repetitively 
inspecting acrylic cabin and cockpit windows for cracks on Fairchild 
Aircraft SA26, SA226, and SA227 series airplanes, and, if cracks are 
found that exceed certain limits, replacing that window. The revision 
document was proposed to more fully define the crack limits and 
establish clearer repetitive inspection intervals under those crack 
limits for the affected airplanes. Several incident reports of cockpit 
side window failures on the affected airplanes that were in compliance 
with AD 93-19-06 has prompted the FAA to propose a modification to 
these windows in another AD action, which would supersede the current 
AD. The FAA is withdrawing the current NPRM and issuing another NPRM to 
propose this modification.

FOR FURTHER INFORMATION CONTACT: Mr. Hung Viet Nguyen, Aerospace 
Engineer, FAA, Airplane Certification Office, 2601 Meacham Boulevard, 
Fort Worth, Texas 76193-0150; telephone (817) 222-5155; facsimile (817) 
222-5959.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations to include an airworthiness directive (AD) that 
would apply to Fairchild Aircraft SA26, SA226, and SA227 series 
airplanes was published in the Federal Register on March 30, 1994 (59 
FR 14795). The action proposed to revise AD 93-19- 06, Amendment 39-
8705, to more fully define the crack limits and establish clearer 
repetitive inspection intervals under those crack limits for the 
affected airplanes. AD 93-19-06 requires repetitively inspecting 
acrylic cabin and cockpit windows for cracks on certain Fairchild 
Aircraft SA26, SA226, and SA227 series airplanes, and, if cracks are 
found that exceed certain limits, replacing that window. The actions 
are accomplished in accordance with the following service bulletins 
(SB), as applicable:

    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.
    Since issuance of the NPRM, the FAA has received several incident 
reports of cockpit side window failures on the affected airplanes. All 
of the airplanes involved in the referenced incidents are in compliance 
with AD 93-19-06. After a review of all available information related 
to the incidents referenced above, the FAA is proposing a modification 
to these windows in another AD action that would supersede AD 93-19-06, 
and is withdrawing the current NPRM.
    Withdrawal of this NPRM constitutes only such action, and does not 
preclude the agency from issuing another notice in the future or commit 
the agency to any course of action in the future.
    Since this action only withdraws an NPRM, it is neither a proposed 
rule nor a final rule and therefore, is not covered under Executive 
Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979).

03-AD, published in the Federal Register on March 30, 1994 (59 FR 
14795), is withdrawn.

    Issued in Kansas City, Missouri, on February 14, 1995.
