Airworthiness Directives; the Cessna Aircraft Company Models 402C
and 414A Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) to
supersede emergency AD 2005-05-51 and AD 2000-23-01 for The Cessna
Aircraft Company (Cessna) Models 402C and 414A airplanes. This AD
contains the same information as emergency AD 2005-05-52 and publishes
the action in the Federal Register. It requires you to eddy current
inspect the forward wing spars and visually inspect the aft and
auxiliary spars. This AD is the result of extensive cracks found on
three wing spars of the affected airplanes. We are issuing this AD to
detect and correct cracking in the wing spars before the cracks grow to
failure. Such a wing failure could result in the wing separating from
the airplane with consequent loss of control of the airplane.
DATES: This AD becomes effective on March 21, 2005, to all affected
persons who did not receive emergency AD 2005-05-52, issued March 2,
2005. Emergency AD 2005-05-52 contained the requirements of this
amendment and became effective immediately upon receipt. As of March
21, 2005, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in the
regulations.
We must receive any comments on this AD by April 30, 2005.

SUPPLEMENTARY INFORMATION: What events caused previous FAA AD action?
The FAA has received reports of (and is analyzing data from) cracks
found in the wings of two Cessna Model 402C airplanes.
On the first airplane, early information indicates the airplane had
severe cracking on its left wing in the vicinity of the forward spar
and outboard engine beam. The main lower spar cap had completely failed
at about Wing Station (WS) 114. The airplane also had cracks in the
lower wing skin and the web splice doubler. Also found were two popped
rivets: one between the heat shield and the wing skin and another
between the factory installed web splice doublers and web. The airplane
had 20,355 total hours time-in-service (TIS).
During the airplane's most recent flights before the cracking was
found, the pilot noticed that roll trim was required. The flights
required the pilot to use aileron trim for level flight to keep the
wings level. The airplane landed safely and inspection revealed the
cracks.
On the second airplane, fatigue cracks were found at about WS 114
in the main lower spar cap of another Model 402C airplane that had over
20,000 total hours TIS. Fatigue analysis shows that similar fatigue
cracks could also develop in the wings of the Model 414A airplanes.
Airworthiness Directive (AD) 2000-23-01, Amendment 39-11971 (65 FR
70645), required repetitive visual inspections of the forward, aft, and
auxiliary wing spars for cracks on Cessna Model 402C airplanes. These
inspections are at intervals not to exceed 110 hours TIS.
Logbook records indicated that both airplanes with cracked spars
were in compliance with AD 2000-23-01.
The FAA's analysis of the incidents presented above showed that, in
the interim, the inspections of AD 2000-23-01 should be done more
frequently and particular attention paid to certain areas.
Therefore, FAA issued Emergency AD 2005-05-51 to detect and correct
cracking in the wing spars of the Cessna Models 402C and 414A airplanes
before the cracks grow to failure. Such a wing failure could result in
the wing separating from the airplane with consequent loss of control
of the airplane.
Emergency AD 2005-05-51 superseded AD 2000-23-01 and:
Required the visual inspections of the forward, aft, and
auxiliary wings spars for cracks more frequently on Model 402C
airplanes including special emphasis areas;
Added inspection requirements for the Model 414A
airplanes; and
Included provisions to position the airplane to a home
base, hangar, maintenance facility, etc.
Emergency AD 2005-05-51 did not affect those airplanes that
incorporate a spar strap modification on each wing following the
original release of (or a later FAA-approved revision to) Cessna
Service Bulletin MEB02-5 and Cessna Service Kit SK402-47 (currently at
MEB02-5 Revision 2 and SK402-47B).
What has caused this particular AD action? Emergency AD 2005-05-51
was considered an interim action to immediately require visual
inspection of the forward, aft, and auxiliary wing spars for cracks.
The intent was to detect immediate and existing cracking before it grew
to wing failure.
The FAA has also received a report of a third crack found at WS 112
on a Model 402C airplane.
Cessna has developed new inspection techniques (eddy current) for
the forward spar that are more effective at detecting cracks before the
structural integrity of the wing is compromised. These inspection
techniques will allow for longer intervals between repetitive
inspections than in emergency AD 2005-05-51.
Recent fatigue analysis that Cessna did (and the FAA reviewed)
reveals that eddy current inspections of the forward wing spars
combined with visual inspections of the aft and auxiliary spars will
address the unsafe condition of these airplanes until long-term
continued operational safety is assured through the Cessna-developed
and FAA-approved spar strap modifications. Specifically:
The eddy current inspection will replace the visual
inspection of the forward spar that emergency AD 2005-05-51 currently
requires; and
The visual inspections of the aft and auxiliary spars will
be maintained from emergency AD 2005-05-51, but will only be required
repetitively every 100 hours TIS instead of every 15 hours TIS.
Cessna has issued the following service information to include
procedures to eddy current inspect the Models 402C and 414A airplanes:
Cessna Service Bulletin MEB99-3, Revision 2, dated
February 28, 2005 (Model 402C); or
Cessna Service Bulletin MEB00-7, Revision 2, dated
February 28, 2005 (Model 414A).
The FAA's Determination
After careful review of all available information related to the
subject presented above, including the above-referenced service
bulletins, FAA has determined that:
The forward wings spars should be inspected using eddy
current methods on Cessna Models 402C and 414A airplanes;
The visual inspections of the aft and auxiliary spars
should be maintained from emergency AD 2005-05-51 (but not inspected as
often); and
AD action should be taken to detect and correct cracking
in the wing spars before the cracks grow to failure. Such a wing
failure could result in the wing separating from the airplane with
consequent loss of control of the airplane.
Consequently, we issued emergency AD 2005-05-52 to supersede
emergency AD 2005-05-51.
Why is it important to publish this AD? The FAA found that
immediate corrective action was required, that notice and opportunity
for prior public comment were impracticable and contrary to the public
interest, and that good cause existed to make the AD effective
immediately by individual letters issued on March 2, 2005, to all known
U.S. operators of Cessna Models 402C and 414A airplanes. These
[[Page 13364]]
conditions still exist, and the AD is published in the Federal Register
as an amendment to section 39.13 of the Federal Aviation Regulations
(14 CFR 39.13) to make it effective to all persons.
Comments Invited
Will I have the opportunity to comment before you issue the rule?
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``Docket No. FAA-2005-20513;
Directorate Identifier 2005-CE-07-AD'' in the subject line of your
comments. If you want us to acknowledge receipt of your mailed
comments, send us a self-addressed, stamped postcard with the docket
number written on it; we will date-stamp your postcard and mail it back
to you. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it. If a person contacts us through a
nonwritten communication, and that contact relates to a substantive
part of this AD, we will summarize the contact and place the summary in
the docket. We will consider all comments received by the closing date
and may amend the AD in light of those comments.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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 AD.
Regulatory Findings
Will this AD impact various entities? We have 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.
Will this AD involve a significant rule or regulatory action? 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); 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.
We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``Docket No. FAA-2005-20513; Directorate Identifier 2005-CE-07-AD'' in
your request.

(a) This AD becomes effective on March 21, 2005, to all affected
persons who did not receive emergency AD 2005-05-52, issued March 2,
2005. Emergency AD 2005-05-52 contained the requirements of this
amendment and became effective immediately upon receipt.
Are Any Other ADs Affected by This Action?
(b) This AD supersedes the following:
(1) Emergency AD 2005-05-51, issued February 20, 2005; and
(2) AD 2000-23-01, Amendment 39-11971.
What Airplanes Are Affected by This AD?
(c) This AD affects Model 402C and 414A airplanes, all serial
numbers, that:
(1) are certificated in any category; and
(2) do not incorporate a spar strap modification on each wing
spar following the original release of (or a later FAA-approved
revision to) Cessna Service Bulletin MEB02-5 and Cessna Service Kit
SK402-47 (currently at MEB02-5 Revision 2 and SK402-47B).
What Is the Unsafe Condition Presented in This AD?
(d) This AD is the result of extensive cracks found on three
wing spars of the affected airplanes. We are issuing this AD to
detect and correct cracking in the wing spars before the cracks grow
to failure. Such a wing failure could result in the wing separating
from the airplane with consequent loss of control of the airplane.
What Must I Do to Address This Problem?
(e) Visual Inspections for all Model 402C airplanes With Fewer
than 15,000 Hours Total Time-in-service (TIS): Initially inspect
upon accumulating 10,000 hours TIS on the airplane or at the next
inspection that would have been required by AD 2000-23-01 or
emergency AD 2005-05-51, whichever occurs later. Repetitively
inspect thereafter at intervals not to exceed 110 hours TIS until
accumulating 15,000 hours TIS:
(1) Perform both a visual external and internal inspection of
the forward, aft, and auxiliary wing spars for cracks.
(2) Do these visual inspections following the Accomplishment
Instructions section of Cessna Service Bulletin MEB99-3 (Model
402C), Revision 2, dated February 28, 2005.
(3) When doing the inspections, pay particular attention to the
following areas:
(i) Just Outboard of the Engine Beam
(A) The main lower spar cap at Wing Station (WS) 114.
(B) The three rivets on both the inboard and outboard sides of
WS 114 (total of six rivets) in the main lower spar cap as viewed
from the access hole.
(C) The main spar web at WS 112.5.
(ii) Just Inboard of the Inboard Engine Beam
(A) The main lower spar cap between WS 80 and WS 89.
(B) The two attach bolts on the main spar just inboard of the WS
89.18 rib.
(f) Eddy Current and Visual Inspections: Perform eddy current
inspections of the forward wing spars combined with visual
inspections of the aft and auxiliary spars. Do these inspections
following the Accomplishment Instructions section of Cessna Service
Bulletin MEB99-3 (Model 402C) or Cessna Service Bulletin MEB00-7
(Model 414A), both at Revision 2 and both dated February 28, 2005.

Wichita Aircraft Certification Office (ACO), by fax: (316) 946-4107.
(i) Include a report for ``cracks found'' or ``no cracks found''
on the initial inspection; and
(ii) Include a report only for ``cracks found'' on the
repetitive inspections.
(2) The report must include your name and a contact phone
number, the results of the findings, a description of any cracking
found, the airplane serial number, and the total number of hours TIS
on the airplane. The ``Lower Wing Spars and Skin Inspection Report''
included in Cessna Service Bulletin MEB99-3 and MEB00-7 may be
utilized for this reporting requirement.
May I Request an Alternative Method of Compliance?
(i) You may request a different method of compliance or a
different compliance time for this AD by following the procedures in
14 CFR 39.19. Unless FAA authorizes otherwise, send your request to
your principal inspector. The principal inspector may add comments
and will send your request to the Manager, Wichita Aircraft
Certification Office (ACO), FAA.
