[Docket No. 96-CE-54-AD; Amendment 39-10821; AD 98-08-25 R1]
RIN 2120-AA64
Airworthiness Directives; Twin Commander Aircraft Corporation
500, 680, 690, and 695 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Direct final rule; confirmation of effective date.
-----------------------------------------------------------------------
SUMMARY: This action confirms the effective date of Airworthiness
Directive (AD) 98-08-25 R1, which applies to certain Twin Commander
Aircraft Corporation (Twin Commander) 500, 680, 690, and 695 series
airplanes. AD 98-08-25 R1 requires replacing the nose landing gear
(NLG) drag link bolt with an approved heat-treated bolt that has the
manufacturer's serial number, manufacture date, and the last three
digits of the drawing number (055) on the bolt head; and changing the
bolt part number (P/N) to be installed on Models 690D and 695A from P/N
ED10055 to P/N 750076-1. This AD was the result of the FAA
inadvertently transposing the serial numbers of the 4 affected Model
695A airplanes. The actions specified in this AD are intended to
prevent the NLG from collapsing due to failure of a drag link bolt,
which could result in loss of control of the airplane during landing
operations.
EFFECTIVE DATE: January 5, 1999.

SUPPLEMENTARY INFORMATION: The FAA published this direct final rule
with request for comments in the Federal Register on October 9, 1998
(63 FR 54347). The FAA uses the direct final rulemaking procedure for a
non-controversial rule where the FAA anticipates that there will be no
adverse public comment. This direct final rule advised the public that
no adverse comments were anticipated, and that unless a written adverse
comment, or a written notice of intent to submit such an adverse
comment, was received within the comment period, the regulation would
become effective on January 5, 1999. No adverse comments were received,
and thus this notice confirms that this final rule becomes effective on
that date.
Issued in Kansas City, Missouri, on December 29, 1998.
