Airworthiness Directives; McCauley Propeller Systems 1A103/TCM
Series Propellers
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), that is applicable to McCauley Propeller Systems 1A103/TCM series
propellers. That AD currently requires an initial inspection for cracks
in the propeller hub in accordance with a dye penetrant inspection
procedure, replacement of propellers with cracks that do not meet
acceptable limits, rework of propellers with cracks that meet
acceptable limits, and repetitive inspections of all affected
propellers. This amendment allows additional rework operations to be
performed at more than one bolt hole location. This amendment is
prompted by the need to clarify the requirement to use a steel backing
plate and Mylar gasket during installation of the propeller, and to
relax the replacement requirements. The actions specified in the
proposed AD are intended to prevent propeller separation due to hub
fatigue cracking, which can result in loss of control of the airplane.
DATES: Effective July 17, 2003. The incorporation by reference of
certain publications listed in the regulations is approved by the
Director of the Federal Register as of July 17, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from McCauley Propeller Systems, 3535 McCauley Drive, PO

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 97-06-16,
Amendment 39-9973 (62 FR 16064, April 4, 1997), which is applicable to
McCauley Propeller Systems 1A103/TCM series propellers, was published
in the Federal Register on September 27, 2002 (67 FR 61043). That
action proposed to require:
[sbull] An initial inspection for cracks in the propeller hub in
accordance with a dye penetrant inspection procedure.
[sbull] Replacement of propellers with cracks that do not meet
acceptable limits.
[sbull] Rework of propellers with cracks that meet acceptable
limits.
[sbull] Painting of the propeller hub before installation of the
propeller.
[sbull] Repetitive inspections of all affected propellers.
[sbull] Installation of a steel backing plate and Mylar gasket
during installation of the propeller.
These actions must be done in accordance with McCauley Propeller
Systems Alert Service Bulletin (ASB) 221C, dated September 7, 1999.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
One commenter agrees with the NPRM as written.
[[Page 35156]]
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule as proposed.
Economic Analysis
There are approximately 6,100 propellers of the affected design in
the worldwide fleet. The FAA estimates that approximately 3,000
propellers installed on airplanes of U.S. registry will be affected by
this AD. The FAA also estimates that it will take approximately 3 work
hours per propeller to perform the required actions, and that the
average labor rate is $60 per work hour. Required parts would cost
approximately $17 per propeller. Based on these figures, the total cost
of the AD to U.S. operators is estimated to be $591,000 per year.
Regulatory Analysis
This final rule does not have federalism implications, as defined
in Executive Order 13132, because it would 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. Accordingly,
the FAA has not consulted with state authorities prior to publication
of this final rule.
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 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. A final evaluation has been prepared for this action
and it 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.
