AD 2018-14-01

We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Models PA-46-600TP (M600) airplanes. This AD requires inserting temporary airspeed limitations into the pilot's operating handbook, installing a temporary placard, inspecting rivets on the cockpit canopy above the left and right cockpit side windows, and installing a repair kit based on the findings of the rivet inspection. This AD was prompted by a report of undersized fasteners installed during manufacturing. We are issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Discussion

We received a report from Piper that some rivets installed through the fuselage skin at the cockpit area during manufacture are below the minimum required strength on certain Model PA-46-600TP (M600) airplanes. This condition, if not corrected, could result in failure of the skin joint resulting in loss of pressurization or fuselage structural failure. We are issuing this AD to correct the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

We reviewed Piper Aircraft, Inc. Service Bulletin No. 1318B, dated June 7, 2018. The service bulletin describes procedures for incorporating temporary airspeed limitations into the pilot's operating handbook (POH) and fabricating and installing an airspeed limitations placard on the airplane until an inspection is completed and a minimum of 16 specific rivets are replaced. The service bulletin also describes procedures for the inspection of the rivets on thecockpit canopy above the left and right cockpit side window and the replacement of the rivets. This service information is reasonably available because the

[[Page 31851]]

interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

FAA's Determination

We are issuing 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.

AD Requirements

This AD requires inserting temporary airspeed limitations into the POH, installing a temporary placard with the airspeed limitations in the cockpit, inspecting the rivets on the cockpit canopy above the left and right cockpit side windows, and installing a repair kit based on the findings of the inspection.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because undersized and understrength rivets through the fuselage skin at the cockpit area could result in failure of the skin joint, which could result in loss of pressurization or fuselage structural failure. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, we find that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

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 send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2018- 0606 and product identifier 2018-CE-018-AD at the beginning of your comments.
We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. We will consider all comments received by the closing date and may amend this final rule because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this final rule.

Costs of Compliance

We estimate that this AD affects 31 airplanes, of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost productoperators ---------------------------------------------------------------------------------------------------------------- Insert airspeed limitations into .5 work-hour x $85 Not applicable........... $42.50 $1,317.50
the POH and install an airspeed per hour = $42.50.
temporary placard. Inspect the size of the cockpit 2 work-hours (1 Not applicable........... 170 5,270
side window rivets. work-hour on each
side) x $85 per
hour = $170. ----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. Each airplane would require one of the kits on each side based on the inspection. We have presented what the cost on U.S. operators would be for each kit on both sides even though each airplane would have one of the two kits on each side and could have different kits on each side. This would make the total cost on U.S. operators significantly less, but we have no way of determining how many would require each kit.

----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Replace rivets using Rivet 16 work-hours (8 work- $6 ($3 each side).... $1,366 $42,346
Replacement Kit, Piper part hours each side) x
number P/N 88623-701. $85 per hour =
$1,360. Replace rivets using Rivet 60 work-hours (30 244 ($122 each side). 5,344 165,664
Replacement Kit, Piper part work-hours each
number P/N 88624-701. side)x $85 per hour
= $5,100. ----------------------------------------------------------------------------------------------------------------

According to the manufacturer, some of the costs of this 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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has

[[Page 31852]]

delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division.

Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have asubstantial 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.
