14 CFR Part 39

[Docket No. FAA-2012-1330; Directorate Identifier 2012-CE-006-AD; 
Amendment 39-17470; AD 2013-11-10]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cessna Aircraft Company (Cessna) (previously COLUMBIA or LANCAIR) 
Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. This AD was 
prompted by reports that during maximum braking, if the brakes lock up 
and a skid occurs, a severe oscillatory yawing motion or ``wheel walk'' 
may develop, which could result in further significant structural 
damage to the airplane. This AD requires insertions into the pilot's 
operating handbook (POH) and the airplane maintenance manuals (AMM) 
regarding proper use of the brakes and inspection of the aft fuselage. 
We are issuing this AD to correct the unsafe condition on these 
products.

DATES: This AD is effective July 26, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 26, 2013.

ADDRESSES: For service information identified in this AD, contact

Kansas 67277; telephone: (316) 517-5800; fax (316) 517-7271; Internet:

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That

[[Page 37449]]

NPRM published in the Federal Register on December 21, 2012 (77 FR 
75590). That NPRM proposed to require insertions into the pilot's 
operating handbook (POH) and the airplane maintenance manuals (AMM) 
regarding proper use of the brakes and inspection of the aft fuselage.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request To Modify the Landing Gear

    Paul Rene LaChance stated that while supportive of the AD, he 
believes it to be too late and does not go far enough. He commented 
that he had experienced such an incident himself. Maximum braking had 
occurred. Afterward, the airplane was flown for a short flight with the 
pilot unaware of the severe tail damage, and the tail almost came off. 
The commenter states we should require modification of the airplane 
with the main landing gear oriented vertical rather than the current 
forward tilt.
    We do not agree with this comment. The controllability of the 
aircraft is not in question if the pilot reduces brake pressure in the 
event of a wheel walking event. The procedures in the AD will ensure 
pilots are aware of appropriate actions and what inspections are 
required if such an event occurs. The commenter may provide 
substantiating data and apply for an alternative method of compliance 
(AMOC) following the procedures in paragraph (i) of this AD to 
implement a design modification.

AD Is Not Necessary and Should Be Withdrawn

    Darryl James Taylor, Steven Masters, William Paul Boyd, Paul 
Harrington, George Richard Wilhelmsen, Todd Thompson, Larry D. Fenwick, 
and Thomas Clare who is President of the Cessna Advanced Aircraft Club 
(CAAC), requested we withdraw the NPRM (77 FR 75590, December 21, 2012) 
because it is unnecessary, does not add to safety, and is ineffective. 
The AD would affect 726 airplanes, and there have only been five 
occurrences out of thousands of landings over the past nine years. The 
commenters do not feel this is statistically significant. Since the AD 
comes several years after an isolated incident, the AD addresses no 
real safety concern. Appropriate notices have already been incorporated 
in POH manuals per Cessna Service Bulletin SB 10-11-01, dated August 
17, 2010. The commenters feel it is unlikely that additional notes to 
the POH or placards will be an effective solution.
    We do not agree with this comment. The wheel walking 
characteristics are highly unusual. We are unaware of any other 
airplane model that has experienced such an event. Currently, the 
events are relatively well publicized, but they may be forgotten or 
unknown to future pilots without previous knowledge about the airplane. 
Adding the changes to the POH and maintenance manual and mandating the 
aft fuselage inspection will assure that someone does not take off 
again after an event without having the airplane inspected. The added 
changes will also help the pilot better know how to handle the airplane 
if the wheel walk event does occur. The AD process is the only means 
where the FAA can require all owner/operators to incorporate all the 
necessary changes and conduct the required inspection. However, owner/
operators that have already incorporated the POH changes per the Cessna 
service bulletin may receive credit for certain actions required by 
this AD.

Engineering Solution Needed

    Darryl James Taylor, William Paul Boyd, Paul Herrington, George 
Richard Wilhelmsen, and Larry D. Fenwick commented that maximum braking 
is considered panic braking where the pilot instinctively reacts to an 
adverse condition, and they feel the real issue is proper maintenance 
training. The braking issue occurs only when the gear bushings have 
slipped completely out, and maintenance shops do not know what they are 
looking at. In which case, the solutions in the AD will be ineffective. 
Probably, the landings were not made under ideal or normal conditions, 
and the pilots may have exceeded operational specifications during 
landing. This issue should have an engineering solution such as anti-
lock brakes, which could prevent brake lock-up and avoid the adverse 
condition. It would address maximum braking, no matter what the cause. 
The anti-lock system would include slotted wheels and Hall sensors and 
change the current braking system. The cost would be justified because 
of the reduced risk of structural damage.
    We do not agree with this comment. Although we would consider a 
design change as an AMOC, we have determined that the requirements in 
this AD are sufficient to address the unsafe condition. The commenters 
may provide substantiating data and apply for an AMOC following the 
procedures in paragraph (i) of this AD to implement a modification as 
an acceptable level of safety to address the unsafe condition.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 75590, December 21, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 75590, December 21, 2012).

Costs of Compliance

    We estimate that this AD affects 726 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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,

[[Page 37450]]

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

    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 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.
