SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
A number of propeller blade outer sleeves
have been found with cracks since 1996.
Testing has shown that blade retention
integrity is not affected by this cracking.
However, this condition, if not detected and
corrected, can lead to blade counterweight
release, possibly resulting in damage to the
aircraft and injury to occupants or persons on
the ground.
We are issuing this AD to prevent blade
counterweight release, which could
result in injury or damage to the
airplane.
DATES: This AD becomes effective
April 7, 2010.
ADDRESSES: The Docket Operations
office is located at Docket Management
Facility, U.S. Department of
Transportation, 1200 New Jersey
Avenue, SE., West Building Ground
Floor, Room W12–140, Washington, DC
20590–0001.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) and a supplemental
NPRM to amend 14 CFR part 39 to
include an AD that would apply to the
specified products. That NPRM was
published in the Federal Register on
June 30, 2008 (73 FR 36819), and the
supplemental NPRM was published in
the Federal Register on May 18, 2009
(74 FR 23131). Those NPRMs proposed
to correct an unsafe condition for the
specified products. The MCAI states
that:
A number of propeller blade outer sleeves
have been found with cracks since 1996.
Testing has shown that blade retention
integrity is not affected by this cracking.
However, this condition, if not detected and
corrected, can lead to blade counterweight

release, possibly resulting in damage to the
aircraft and injury to occupants or persons on
the ground.
Comments
We gave the public the opportunity to
participate in developing this AD. We
responded to the comments received on
the NPRM, in the supplemental NPRM.
We considered the one comment
received on the supplemental NPRM, as
follows:
Claim That Tracking of Individual
Propeller Blades Is Not Required
One commenter, a private citizen,
states that if the proposed AD was
rewritten against the propeller
assembly, instead of the propeller
blades, then all four propeller blades are
inspected at the same time, and tracking
of individual propeller blades is not
required. Also, because the propeller
blades could be moved from propeller to
propeller, a requirement to inspect all
four propeller blades at the time the
propeller is assembled, ‘‘zeroing out’’ the
inspection, would prevent any propeller
blade in the assembly from exceeding its
inspection interval.
We do not agree. Since the propeller
blade log cards are with the propeller
blades, it is appropriate in writing the
AD against the propeller blades; not the
propeller assembly. Also, since the AD
is related to propeller blade inspections,
and propeller assembly total time is
independent of propeller blade total
time, tracking propeller assembly time
could result in a propeller blade
exceeding the 1,600 flight hour or
15,000 flight hour time-in-service
inspection interval. We did not change
the AD.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD as proposed.
Costs of Compliance
Based on the service information, we
estimate that this AD will affect about
292 propellers installed on airplanes of
U.S. registry. We also estimate that it
will take 0.5 work-hour per propeller to
visually inspect for cracks. The average
labor rate is $80 per work-hour. Based
on these figures, we estimate the cost of
the AD on U.S. operators to be $11,680.
