Federal Register Abstract
We are superseding Airworthiness Directive (AD) 2001-12- 18 for certain CASA Model CN-235 series airplanes. AD 2001-12-18 required modification of the rigging of the engine control cable assembly and replacement of either the entire engine control cable assembly or a segment of the control cables. This new AD would retain the requirements of AD 2001-12-18. This new AD also requires repetitive replacements of each power lever and condition lever Teleflex cable with a new or serviceable part, and removes airplanes from the applicability. This AD was prompted by reports of new occurrences of cable disruption on a certain part number; the disruption is caused by microcracks along the cable surface. We are issuing this AD to prevent fatigue of the engine control cables, leading to breakage of the cables, which could result in reduced controllability of the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2001-12-18, Amendment 39-12274 (66 FR 33014,
June 20, 2001) (``AD 2001-12-18''). AD 2001-12-18 applied to certain
CASA Model CN-235 series airplanes. The NPRM published in the Federal
Register on January 19, 2016 (81 FR 2783) (``the NPRM'').
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2014-0262, dated December 5, 2014 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for certain Airbus
Defense and Space S.A. Model CN-235-100 and -200 airplanes. The MCAI
states:
Three occurrences of cable disruption were reported in 1999. The
failed parts, having a part number (P/N) 7-44728-20, were part of
the engine control system assembly P/N 7-44728-12. Two cables were
connected to the Power Lever and one cable to the Condition Lever
control. Service records of the affected parts showed that each
cable accumulated more than 14,000 flight cycles (FC).
The subsequent investigation determined that the disruption was
attributed to fatigue related crack.
This condition, if not corrected, could lead to failure of the
engine control system resulting in a loss of the affected engine
control.
Prompted by this unsafe condition, DGAC [Direcci[oacute]n
General de Aviaci[oacute]n Civil] Spain issued AD 03/00 [which
corresponds to FAA AD 2001-12-18] to require rigging of the throttle
stops, and one-time replacement of the affected engine control cable
assembly (P/N 7-44728-12), or the affected cable (P/N 7-44728-20)
before exceeding 12,000 FC.
After that [DGAC Spain] AD was issued, a new occurrence of cable
(P/N 72830-20) disruption was reported. In that case, the affected
cable was part of the Condition Lever control and had accumulated
8,497 flight hours (FH) and 8,858 FC. Fractographic analysis of the
affected cable identified that the fatigue nucleation seemed to have
been induced by microcracks along the cable surface. Additionally,
another case of control cable (P/N 72830-20) failure was reported,
where the affected part accumulated 9,936 FH and 10,552 FC and was
part of the Power Lever control. Investigation of the latter case
identified again a fatigue nucleation to be the cause of the cable
failure.
To address this potentially unsafe condition, Airbus Military
issued Alert Operators Transmission (AOT) AOT-CN235-76-0001 to
provide a repetitive replacement interval and instructions.
For the reasons described above, this [EASA] AD retains the
requirements of DGAC Spain AD No. 03/00, which is superseded, but
requires repetitive replacement [at reduced thresholds] of the
affected Teleflex cables.
You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2015-
8465.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Clarification of Applicability
We have clarified the Applicability in paragraph (c) of this AD.
For Model CN-235 airplanes, the affected serial numbers (S/N) are C-001
through C-015 inclusive. We have removed S/N C-074 for Model CN-235
airplanes because there are no Model CN-235 airplanes with that serial
number.
For Model CN-235-100 and -200 airplanes, the affected serial
numbers are C-016 through C-073 inclusive. We have removed S/Ns C-001
through C-015 inclusive and C-074 for CN-235-100 and -200 airplanes
because there are no Model CN-235-100 and -200 with those serial
numbers.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting this AD with the changes described
previously and minor editorial changes. We have determined that these
minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR Part 51
Airbus Defense and Space S.A. has issued Airbus Military Alert
Operators
[[Page 34878]]
Transmission AOT-CN235-76-0001, dated May 27, 2014. This service
information describes repetitive replacements of each power lever and
condition lever Teleflex cable having a certain part number with a new
or serviceable part. This service information also provides a new life
limit of 5,000 flight cycles. This service information is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 3 airplanes of U.S. registry.
The rigging required by AD 2001-12-18, and retained in this AD
takes about 8 work-hours per product, at an average labor rate of $85
per work-hour. Based on these figures, the estimated cost of the
rigging that was required by AD 2001-12-18 is $680 per product.
The replacement required by AD 2001-12-18, and retained in this AD
takes about 47 work-hours per product, at an average labor rate of $85
per work-hour. Required parts cost about $1,444 per product. Based on
these figures, the estimated cost of the replacement that was required
by AD 2001-12-18 is $5,439 per product.
We also estimate that it would take about 47 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts would cost about $6,480 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $31,425, or $10,475 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will 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.
For the reasons discussed above, I certify that this AD:
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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
