14 CFR Part 39
[Docket No. 2002-CE-23-AD; Amendment 39-13772; AD 2004-17-01]
RIN 2120-AA64
Airworthiness Directives; Cessna Aircraft Company Models 208 and
208B Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA supersedes Airworthiness Directive (AD) AD 2002-22-17,
which applies to all Cessna Aircraft Company (Cessna) Models 208 and
208B airplanes; and AD 2003-21-04, which applies to certain Cessna
Models 208 and 208B airplanes. This AD requires you to repetitively
inspect the flap bellcranks for cracks and eventually replace these
bellcranks. The installation of a newly designed bellcrank to increase
the life limits is terminating action for the repetitive inspections.
This AD is the result of these developments: Since FAA issued AD 2002-
22-17 and AD 2003-21-04, Cessna designed a new flap bell crank with a
life limit of 40,000 landings instead of 7,000 landings. Also, FAA has
done more analysis and examination of cracks and missing/incomplete
welds in all of the bell cranks. This failure could lead to damage to
the flap system and surrounding structure and result in reduced or loss
of control of the airplane.
DATES: This AD becomes effective on September 26, 2004.
As of December 31, 2002 (67 FR 68508, November 12, 2002), the
Director of the Federal Register approved the incorporation by
reference of Cessna Service Bulletin No. CAB02-1, dated February 11,
2002.
As of October 21, 2003 (68 FR 59707, October 17, 2003), the
Director of the
[[Page 50057]]
Federal Register approved the incorporation by reference of the
following:
Cessna Caravan Service Bulletin No.: CAB03-11, Revision 1, dated
September 24, 2003;
Cessna Caravan Service Bulletin No.: CAB02-12, revision 1, dated
January 27, 2003; and
Cessna Caravan Service Kit No.: SK208-148A, dated January 27, 2003

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The need to reduce the life limit
and repetitively inspect the inboard forward flap bellcrank on Cessna
Models 208 and 208A airplanes caused us to issue AD 2002-22-17,
Amendment 39-12944 (67 FR 68508, November 12, 2002); and AD 2003-21-04,
Amendment 39-13339 (68 FR 59707, October 17, 2003).
Since FAA issued AD 2002-22-17 and AD 2003-21-04, Cessna has
designed a new flap bellcrank, part number (P/N) 2622311-7, with a life
limit of 40,000 landings (instead of 7,000 landings). The new flap
bellcrank (P/N 2622311-7) may be substituted for the older flap
bellcranks, P/N 2622281-2, 2622281-12, or 2692001-2. Installation of
this new flap bellcrank will eliminate the need for repetitive
inspections.
What is the potential impact if FAA took no action? Cracks in the
bellcrank could result in failure of this part. This failure could lead
to damage to the flap system and surrounding structure and result in
reduced or loss of control of the airplane.
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to all Cessna Models 208 and 208B
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on July 28, 2003 (68 FR 44252).
The NPRM proposed to revise AD 2002-22-17 by proposing a new AD that
would:
--Retain the actions from AD 2003-21-04, and add all flap bellcranks to
the applicability;
--Retain the requirements of AD 2002-22-17; and
--Provide the option of installing the 40,000 landings life limit
bellcranks.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. The following
presents the comments received on the proposal and FAA's response to
each comment:
Comment Issue No. 1: Identify the New Flap Bellcrank (Part Number (P/N)
2622311-16)
What is the commenter's concern? The commenter writes that
including by P/N this new flap bellcrank, which has a 40,000 landings
life limit, in paragraph (f)(2)(ii) of the AD would be a good idea. We
conclude that the commenter wants this specific bellcrank identified by
part number to make this an obvious alternative bellcrank.
What is FAA's response to the concern? We are not incorporating the
commenter's recommendation because the proposal already identifies the
intent. The FAA already allows installation of any new design flap
bellcrank by the words ``* * *Or FAA approved equivalent P/N.'' If we
included this P/N, we would be obligated to revise the AD every time a
new part was designed including part manufacturer approvals (PMAs).
Therefore, we are not changing the final rule AD action based on
this comment.
Comment Issue No. 2: Allow Welding of Any Bellcrank With Missing Welds
What is the commenter's concern? The commenter recommends that FAA
change the AD to allow welding of the bellcrank following Cessna
Caravan Service Bulletin CAB03-11, Revision 1, dated September 24,
2003, except for the right hand inboard forward bellcrank. The
commenter writes that this welding should be allowed since Cessna
identifies welding in the above service bulletin.
What is FAA's response to the concern? The FAA disagrees with the
commenter's recommendation. The FAA has determined that the unsafe
condition is prevented through inspection of the applicable Bellcranks,
with necessary replacements.
Therefore, we are not changing the final rule AD action based on
this comment.
Comment Issue No. 3: Include Visual Inspection of the Aileron Bellcrank
What is the commenter's concern? The commenter recommends that in
this AD that FAA allow inspection of the aileron bellcrank since Cessna
Caravan Service Bulletin CAB04-3 requires visual inspection of the
aileron bellcrank.
What is FAA's response to the concern? We disagree with the
commenter's recommendation. Based on FAA's evaluation to this point,
the unsafe condition is prevented through the inspections specified in
the AD, with necessary replacement. The FAA will consider alternative
methods of compliance (AMOC) on a case-by-case basis.
We are not changing the final rule AD action based on this comment.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for the
changes discussed above and minor editorial corrections. We have
determined that these changes and minor corrections:
--Are consistent with the intent that was proposed in the NPRM for
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many airplanes does this AD impact? We estimate that this AD
affects 1,300 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected airplanes? For the actions retained from AD 2003-21-04, and
the addition of all
[[Page 50058]]
bellcranks to the applicability, we estimate the following costs to do
this inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
2 workhours x $65 per hour = $130. No cost for parts... $130 $130 x 1,300 = $169,000
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements of
the right inboard forward flap bellcrank (P/N 2622311-7, alternate P/N
2622311-16) that would be required based on the results of this
inspection. We have no way of determining the number of airplanes that
may need this replacement:
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary replacements of
the left outboard flap bellcrank (P/N 2622091-17) that would be
required based on the results of this inspection. We have no way of

For the requirements from AD 2002-22-17 that you repetitively
inspect the inboard forward flap bellcranks for cracks, eventually
replace these bellcranks, and provides the option of installing the new
design flap bellcrank to increase the life limits and terminate the
repetitive inspections, we estimate the following costs to do the
inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65... No cost for parts... $65 $65 x 1,300 = $84,500
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any replacements using the
same flap bellcrank (P/N 2622281-2, 2622281-12, 2692001-2, or FAA-
approved equivalent P/N) that will be required based on the inspection
or the reduced life limits:
--------------------------------------------------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Total cost per airplane Total cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
3 workhours x $65 per hour = $195....... $1,793 $195 + $1,793 = $1,988 $1,988 x 1,300 = $2,584,400
--------------------------------------------------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any replacements using the
new flap bellcrank (P/N 2622311-7 or FAA-approved equivalent P/N) that
will be required based on the inspection or the reduced life limits. We
have no way of determining the number of airplanes that may need this
replacement with the new flap bellcrank:
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Total cost per airplane
----------------------------------------------------------------------------------------------------------------
3 workhours x $65 per hour = $195............ $1,845 $195 + $1,845 = $2,040
