2015-28198. Airworthiness Directives; Quest Aircraft Design, LLC Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Quest Aircraft Design, LLC Model KODIAK 100 airplanes. This proposed AD was prompted by a report of limited control yoke movement of the elevator control system due to cushion edging jammed in the elevator control anti-rotation guide slot. This proposed AD would require repetitively inspecting the elevator control system cushion edging for proper condition; replacing the cushion edging; and at a specified time terminating the repetitive inspections by installing wear pads on the elevator bearing assemblies. We are proposing this AD to correct the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by December 21, 2015.

Discussion

We received a report that, during a preflight inspection, an operator noted limited travel of the control yoke on a Quest Aircraft Design, LLC Model KODIAK 100 airplane. Upon further inspection of the control yoke system forward of the control yoke, cushion edging was found jammed in the elevator control anti-rotation guide slot. The jammed edging prevented the control yoke from having full nose up and nose down travel. The operator also reported the same problem on a different KODIAK 100 airplane in which the cushion edging plastic portion separated from the metal track.

Investigation revealed that over time the cushion edging may become worn and degrade. This condition, if not corrected, could result in failure of the elevator control system cushion edging, which could restrict elevator control yoke movement and cause loss of control.

Relevant Service Information

We reviewed Quest Aircraft KODIAK Mandatory Service Bulletin SB14-07, dated August 26, 2014; Quest Aircraft Field Service Instruction, Elevator Control System—Cushion Edging Inspection, Report No. FSI-105, Revision 00, not dated; Quest Aircraft KODIAK 100 Recommended Service Bulletin SB15-01, dated March 26, 2015; and Quest Aircraft Field Service Instruction, Yoke Anti-Rotation Guide Wear Pad Upgrade, Report No. FSI-108, Revision 00, not dated. The service information describes procedures for repetitively inspecting the cushion edging installed on the elevator control anti-rotation guide for proper condition, wear, and security, and replacing if necessary; and removing the cushion edging and installing wear pads on the pilot and co-pilot arms of the elevator bearing assemblies as a terminating action to the repetitive inspections of the cushion edging. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM.

FAA's Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified in the service information described previously.

Costs of Compliance

We estimate that this proposed AD affects 60 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Inspect the cushion edging on each side of the elevator control anti-rotation guide slot	.5 work-hour × $85 per hour = $42.50 per inspection	Not applicable	$42.50 per inspection	$2,550 per inspection.
Required terminating action for repetitive inspections—replace cushion edging with wear pads	3 work-hours × $85 per hour = $255	$200	$455	$27,300.

We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need this replacement:

On-Condition Costs

Action	Labor cost	Parts cost	Cost per product
Replace cushion edging	1 work-hour × $85 per hour = $85	$20	$105

According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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, 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

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

(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),

(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.

List of Subjects in 14 CFR Part 39
