Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
We propose to revise airworthiness directive (AD) 2014-12-11 for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. AD 2014-12-11 currently requires revising the Rotorcraft Flight Manual (RFM) to include the appropriate operating limitations for performing Class D external load-combination operations. As published, AD 2014-12-11 references an incorrect date for Revision No. 12 of Sikorsky RFM SA S92A-RFM-003, Part 1. This proposed AD would correct the error while retaining the requirements of AD 2014-12-11. These proposed actions are intended to require appropriate operating limitations to allow operators to perform Class D external load-combination operations, including human external cargo, in this model helicopter that now meets the Category A performance standard.
We must receive comments on this proposed AD by November 12, 2014.
You may send comments by any of the following methods:

Start Supplemental Information
We invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time.
We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive.
AD 2014-12-11, amendment 39-17872 (79 FR 45085, August 4, 2014), applies to Sikorsky Model S-92A helicopters and requires revising the RFM to include the appropriate operating limitations for performing Class D external load-combination operations. When AD 2014-12-11 was published, an incorrect reference to the date of the RFM revision appeared in the text of the rule.
Specifically, the AD included the following under paragraph (f), Credit for Actions Previously Completed: “Incorporation of the changes contained in Sikorsky RFM SA S92A-RFM-003, Part 1, Revision No. 12, approved March 21, 2005, before the effective date of this AD is considered acceptable for compliance with the corresponding actions specified in paragraph (e) of this AD.” As published, the reference to March 21, 2005, is incorrect. The correct approval date for Revision 12 is December 9, 2010.
The FAA has determined that it is appropriate to revise AD 2014-12-11 to correct the RFM approval date. This revision would clarify any confusion regarding which RFM revision is acceptable to obtain credit for previous actions.
No other part of the preamble or regulatory information has been changed. The final rule would be reprinted in its entirety for the convenience of affected operators.
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.
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, 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 to the extent that it justifies making a regulatory distinction; 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.
We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39—AIRWORTHINESS DIRECTIVES
Start Amendment Part
1. The authority citation for part 39 continues to read as follows: End Amendment Part
Start Amendment Part
2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2014-12-11, Amendment 39-17872 ( 79 FR 45085, August 4, 2014), and by adding the following new AD:End Amendment Part
Sikorsky Aircraft Corporation: Docket No. FAA-2009-1088; Directorate Identifier 2008-SW-76-AD.
This AD applies to Sikorsky Aircraft Corporation Model S-92A helicopters, certificated in any category.
(b) Unsafe Condition
This AD defines the unsafe condition as an inaccurate Rotorcraft Flight Manual (RFM) provision, which was approved without appropriate limitations for this model helicopter for carrying Class D external rotorcraft-load combinations, including Human External Cargo (HEC), when this model helicopter was not certificated to Category A one-engine inoperative (OEI) performance standards, including fly away Start Printed Page 63857capabilities after an engine failure, which is required for carrying HEC.
(c) Affected ADs
This AD revises AD 2014-12-11, Amendment 39-17872 (79 FR 45085, August 4, 2014).
(d) Comments Due Date
We must receive comments by November 12, 2014.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
(f) Required Actions
Within 90 days, revise the Operating Limitations section of Sikorsky Rotorcraft Flight Manual (RFM) SA S92A-RFM-003, Part 1, Section I, by inserting a copy of this AD into the RFM or by making pen and ink changes, as follows:
(1) In the “Types of Operation” section, beneath Hoist, add the following: “The hoist equipment certification installation approval does not constitute approval to conduct hoist operations. Operational approval for hoist operations must be granted by the Federal Aviation Administration. No cabin seats may be installed in front of station 317 when conducting Human External Cargo hoist operations, which requires Category A performance capabilities.”
(2) In the “Flight Limits” section, add the following: “ “HOIST” When conducting Human External Cargo operations, which require category ‘A' performance capabilities, the minimum hover height is 20 feet AGL and the maximum hover height is 80 feet AGL. “HOIST” The collective axis must remain uncoupled when conducting Human External Cargo, which requires category `A' performance capabilities, for the period of time that the person is off the ground or water and not in the aircraft. This can be accomplished by either uncoupling the collective axis or by the pilot depressing the collective trim switch during the pertinent portion of the maneuver.”
(3) In the “Weight Limits” section:
(i) Remove the following: “NOTE: The 150 pound hoist decrement does not preclude Cat A operations at a gross weight of 26,500 pounds with a hoist installed. If conditions permit, the pilot may go to the right of the 26,500 line on Figure 1-2 to determine a maximum gross weight up to 26,650 and then subtract 150 pounds.”
(ii) Add the following: “NOTE: If conditions permit, the pilot may go to the right of the 26,500 pound line on Figure 1-2 to determine the maximum gross weight and then subtract a 150 pound hoist decrement. The maximum gross weight for category `A' operations cannot exceed 26,500 pounds (12,020 kilograms).”
(iii) Add the following and insert Figure 1 to Paragraph (f)(3)(iii) of this AD: “ “HOIST” Maximum gross weight for Human External Cargo, which requires category `A' performance capabilities, is limited to the gross weight determined in accordance with the following Figure 1 to Paragraph (f)(3)(iii) of this AD for your altitude and temperature with the air-conditioner, anti-ice, and bleed air turned off.”
Note 1 to paragraph (f)(3)(iii) of this AD:
Figure 1 to Paragraph (f)(3)(iii) of this AD becomes Figure 1-2A when inserted in the “Weight Limits” section of your RFM.
