Airworthiness Directives; 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 AD 2005-05-52 (70 FR 13362, March 21, 2005), which applies to 
all Cessna Aircraft Company (Cessna) Models 402C and 414A airplanes. AD 
2005-05-52 currently requires you to eddy current inspect the forward 
wing spars and visually inspect the aft and auxiliary spars. This AD is 
the result of fatigue and crack growth analyses of the wings of these 
airplanes, recent cracks found on Model 402C airplanes, and the FAA's 
determination that repetitive inspections and a wing spar modification 
are necessary to address the unsafe condition. Consequently, this AD 
would require repetitive eddy current inspections, visual inspections, 
and a spar strap modification on each wing. You must retain the actions 
of AD 2005-05-52 until you do the modifications of this AD. The actions 
specified by this AD are intended to prevent wing spar cap failure 
caused by undetected fatigue cracks. Such failure could result in loss 
of a wing with consequent loss of airplane control. FAA is also issuing 
AD 2005-12-12 to require the spar strap modification and long-term 
inspections on Models 401, 401A, 402, 402A, 402B, 411, and 411A 
airplanes.

DATES: This AD becomes effective on June 22, 2005.
    As of June 22, 2005, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.
    We must receive any comments on this AD by August 3, 2005.

SUPPLEMENTARY INFORMATION:

What Events Have Caused This AD?

Initial AD Action

    FAA issued AD 99-11-13 (64 FR 29781, June 3, 1999), requiring 
inspections of the forward, aft, and auxiliary wing spars for cracks on 
Cessna Models 402C airplanes with repair or replacement as necessary. 
AD 99-11-13 also required the operator to report the results of the 
inspections to FAA. AD 99-11-13 resulted from an accident where the 
right wing of a Cessna 402C failed just inboard of the nacelle at Wing 
Station (WS) 87. Investigation revealed fatigue cracking of the forward 
main spar that initiated at the edge of the front spar forward lower 
spar cap. FAA determined the spar cap cracking could continue to 
develop over the life of the affected airplanes and issued AD 2000-23-
01, Amendment 39-11971 (65 FR 70645, November 27, 2000), to require 
repetitive inspections of the forward, aft, and auxiliary wing spars 
for cracks on Cessna Models 402C airplanes with repair or replacement 
as necessary.
    Accomplishment of the actions mandated by AD 2000-23-01 required 
following Cessna Service Bulletin MEB99-3, dated May 6, 1999.

Wing Analysis

    Cessna analyzed the wing, including fatigue and crack growth 
analyses, on the affected airplanes. Analysis included:

--A determination of the probable location and modes of damage based on 
analytical results, available test data, and service information;
--Classical fatigue analyses;
--Crack growth and residual strength analyses including use of linear 
elastic fracture mechanics methods;
--Full-scale ground testing to validate analytical models; and
--A flight strain survey to develop stress spectra used in the 
analyses.

    Based on the analysis, Cessna found that the eddy current method 
will not find the crack until it is .03 inch longer than the critical 
crack length. When the crack reaches the critical length, it is not 
reliably detectable because it is under the head of the fastener. Once 
the main spar cap is severed, the remaining structure will no longer 
meet the residual strength requirements. Wing separation could then 
occur under loading conditions less than those established for the 
design limit load.
    Cessna reported only one instance where use of the NDI eddy current 
procedure detected cracks. There are other reported instances where 
cracks were detected visually on the aft flange in the wheel well area. 
The access doubler flanges cover a large percentage of the forward spar 
flange, hampering the effectiveness of visual inspections.
    To meet industry NDI standards, cracks need to be found on Cessna 
Models 402C and 414A airplanes through NDI inspection methods with a 
90-percent probability of detection at a 95-percent confidence level.
    Cessna's analysis indicates the probability and confidence levels 
are not being met. The FAA concurs.

Action Based on Cessna's Analysis

    We issued proposals to amend part 39 of the Federal Aviation 
Regulations (14 CFR part 39) to include two ADs that would apply to 
Cessna Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, and 
414A airplanes. These proposals (Docket Nos. 2002-CE-05-AD and 2002-CE-
57-AD) published in the Federal Register as notices of proposed 
rulemaking (NPRMs) on May 15, 2003 (68 FR 26239 and 68 FR 26244). The 
NPRMs proposed the following:
     Docket No. 2002-CE-05-AD: applied to Cessna Models 401, 
401A,

[[Page 34326]]

401B, 402, 402A, 402B, 411, and 411A airplanes and proposed to 
supersede AD 79-10-15 with a new AD that would require one of the 
following (depending on the aircraft configuration):
[check] For airplanes that do not incorporate one of the specified 
Cessna Service Kits: repetitively inspect the wing spar caps for 
fatigue cracks and repair or replace the wing spar caps as necessary 
and incorporate a spar strap modification on each wing spar; or
[check] For airplanes that incorporate one of the specified Cessna 
Service Kits: repetitively inspect the wing spar caps and straps for 
fatigue cracks and repair or replace the wing spar caps and straps as 
necessary.
[check] Docket No. 2002-CE-57-AD: applied to Cessna Models 402C and 
414A airplanes and proposed to supersede AD 2000-23-01 with a new AD 
that would require you to:
[check] Inspect the wing spar caps for fatigue cracks;
[check] Repair or replace the wing spar caps as necessary; and
[check] Incorporate a spar strap modification on each wing spar.
    The FAA invited interested persons to participate in the 
development of these amendments during the original 75-day comment 
periods. We extended the comment periods for another 30 days and then 
reopened the comment periods for another 60 days. We received numerous 
comments on the NPRMs.
    In addition, FAA held two public meetings: One on March 3 and 4, 
2004, in Herndon, Virginia, and another on August 18, 2004, in Kansas 
City, Missouri. The public meetings allowed an open flow of 
communication among FAA, the public, and industry on issues related to 
the NPRMs.
    After analyzing all information related to this subject, FAA 
decided not to issue the ADs as proposed, and that the best way to 
address the unsafe condition is for FAA, the public, and industry to 
develop alternative solutions to address the unsafe condition.
    Therefore, FAA withdrew the two NPRMs and gathered the necessary 
information to address the situation. That information led to FAA's 
determination, at that time, to initiate AD action against the Models 
401, 401A, 401B, 402, 402A, 402B, 411, and 411A airplanes; and not 
against the Models 402C and 414A airplanes. The plan was to address the 
action through the regular rulemaking process with a notice of proposed 
rulemaking.

Most Recent Service History

    In 2005, the FAA received reports of (and analyzed data from) 
cracks found in the wings of two Cessna Model 402C airplanes.
    On the first airplane, information indicated 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 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 to maintain level flight. 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.
    Logbook records indicated that both airplanes with cracked spars 
were in compliance with AD 2000-23-01. The FAA received a third report 
of another cracked spar found at WS 114 on one of the two Model 402C 
incident airplanes.
    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 
incorporated 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).

Long-Term Continued Operational Safety

    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 immediately detect 
existing cracking before it grew to wing failure.
    Cessna 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 allow for longer intervals between repetitive inspections 
than in emergency AD 2005-05-51. Based on this, FAA issued AD 2005-05-
52, Amendment 39-14022 (70 FR 13362, dated March 21, 2005).
    However, based on the analysis and recent service history, the FAA 
has determined that the long-term operational safety of the Cessna 
airplanes addressed by AD 2005-05-52 can only be assured through the 
incorporation of a spar strap modification and long-term repetitive 
inspections. Since the Models 402C and 414A airplanes have a similar 
type design to that of Models 401, 401A, 401B, 402, 402A, 402B, 411, 
and 411A airplanes, FAA is also issuing AD 2005-12-12 to require the 
spar strap modification and long-term repetitive inspections on those 
airplanes.
    What is the potential impact if FAA took no action? Wing spar cap 
failure caused by undetected fatigue cracks could result in loss of a 
wing with consequent loss of airplane control.
    Is there service information that applies to this subject? Cessna 
has issued the following: Cessna Multi-engine Service Bulletin MEB02-5, 
Revision 2, dated August 2, 2004, and Service Kit SK402-47B, dated 
August 2, 2003.
    This service information includes procedures for inspecting lower 
wing spar caps and incorporating a spar strap modification.

FAA's Determination and Requirements of the AD

    What has FAA decided? We have evaluated all pertinent information 
and identified an unsafe condition that is likely to exist or develop 
on other products of this same type design.
    Since the unsafe condition described previously is likely to exist 
or develop on other Cessna Aircraft Company Models 402C and 414A 
airplanes of the same type design, we are issuing this AD to detect and 
correct wing spar cap failure caused by undetected fatigue cracks. Such 
failure could result in loss

[[Page 34327]]

of a wing with consequent loss of airplane control.
    What does this AD require? This AD supersedes AD 2005-05-52 with a 
new AD that incorporates the actions in the previously-referenced 
service bulletins and retains the actions of AD 2005-05-52 until you do 
the modifications of this AD.
    Why do the compliance times of this AD range between 400 hours TIS 
and 800 hours TIS? We have established the compliance times based on 
risk analysis that also allows for compliance scheduling. The 
compliance time range is based on total hours TIS, which will address 
those high-usage airplanes first.
    We are issuing this AD as a final rule; request for comments 
instead of a notice of proposed rulemaking (NPRM). We have evaluated 
comments from the previous AD actions on this subject and the two 
public meetings as well as the incidents that have occurred since 
(e.g., the actions of Emergency AD 2005-05-52). Based on this, FAA has 
determined that addressing the unsafe condition with public comment 
prior to issuing this AD action is impracticable. The FAA will evaluate 
any new comments received and amend the AD as necessary.
    How does the revision to 14 CFR part 39 affect this AD? On July 10, 
2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 
22, 2002), which governs 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.

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-05-21177; Directorate 
Identifier 2005-CE-26-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 
other information as included in the Regulatory Evaluation) 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 ``AD 
Docket FAA-05-21177; Directorate Identifier 2005-CE-26-AD'' in your 
request.
