Start Preamble

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.

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 Start Printed Page 37449NPRM 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, Start Printed Page 37450Part 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.
