Federal Aviation Administration
14 CFR Part 39
[Docket No. 95-NM-190-AD; Amendment 39-9398; AD 95-20-51]
Airworthiness Directives; Boeing Model 767-200 and -300 Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; extension of comment period.
-----------------------------------------------------------------------
SUMMARY: This document announces an extension of the comment period for
Airworthiness Directive (AD) 95-20-51, applicable to all Model 767-200
and -300 series airplanes. That AD invites comments concerning the
requirement to inspect the lower half of the aft trunnion of the main
landing gear (MLG) to detect damage, cracking, missing pieces, or
corrosion; and correction of discrepancies. This extension of the
comment period is necessary to afford all interested persons an
opportunity to present their views on the requirements of that AD.
DATES: Effective October 17, 1995, to all persons except those persons
to whom it was made immediately effective by telegraphic AD T95-20-51,
issued September 25, 1995.
Comments for inclusion in the Rules Docket must be received on or
before February 12, 1996.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-103,
Attention: Rules Docket No. 95-NM-190-AD, 1601 Lind Avenue SW., Renton,
Washington 98055-4056.
Information concerning this AD may be examined at the FAA,
Transport Airplane Directorate, 1601 Lind Avenue SW., Renton,
Washington; or at the Office of the Federal Register, 800 North Capitol
Street NW., suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: James G. Rehrl, Aerospace Engineer,
Airframe Branch, ANM-120S, FAA, Transport Airplane Directorate, Seattle
Aircraft Certification Office, 1601 Lind Avenue, SW., Renton,

SUPPLEMENTARY INFORMATION: On October 4, 1995, the FAA issued AD 95-20-
51, amendment 39-9398 (60 FR 53109, October 12, 1995), applicable to
all Boeing Model 767-200 and -300 series airplanes, which requires that
operators perform an external general visual inspection of the lower
half of the aft trunnion of the main landing gear (MLG) to detect
damage, cracking, missing pieces, or corrosion emanating from the aft
trunnion bushing fillet seal or from the aft trunnion crossbolt hole.
That AD invites comments on regulatory, economic, environmental, and
energy aspects of the rule. -
That action was prompted by reports of fractures of the outer
cylinder aft trunnion due to stress corrosion cracking. This condition,
if not corrected, could result in collapse of the MLG due to the
problems associated with stress corrosion cracking in the aft trunnion
assembly; collapse of the MLG could lead to loss of control of the
airplane during landing, taxiing, and takeoff. -
Since the issuance of that AD, a commenter to the rule requested an
extension of the comment period. The commenter states that the
additional time would provide the public with time to study the
requirements of the AD and prepare comments for the Rules Docket. -
The FAA has considered this request and finds it appropriate to
extend the comment period to give all interested persons additional
time to examine the requirements of the AD and submit comments.
Accordingly, the comment period for AD 95-20-51 is extended to February
12, 1996. It should be noted that the effective date of AD 95-20-51 was
October 17, 1995; this action does not change that date. Since no other
portion of that AD or regulatory information has been changed, the
entire rule is not being republished.
Issued in Renton, Washington, on November 28, 1995.

Transport Airplane Directorate, Aircraft Certification Service.
