Airworthiness Directives; Sikorsky 

Aircraft Corporation Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Sikorsky Aircraft Corporation (Sikorsky) 

Model S–76C helicopters. This 

proposed AD would require inspecting 

the engine collective position 

transducer (CPT). This proposed AD is 

prompted by reports of wear of the CPT 

that has resulted in several One Engine 

Inoperative (OEI) incidents. The 

proposed actions are intended to detect 

and prevent an unsafe condition on 

these products. 

DATES: We must receive comments on 

this proposed AD by November 13, 

2017. 

ADDRESSES: You may send comments by 

any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

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. 

Discussion 

We propose to adopt a new AD for 

Sikorsky Model S–76C helicopters with 

a Turbomeca, S.A., Arriel 2S1 or Arriel 

2S2 engine and with a CPT part number 

(P/N) 76900–01821–104 installed. This 

proposed AD is prompted by 20 reports 

of One Engine Inoperative (OEI) 

incidents resulting from wear of a CPT. 

One of these incidents resulted in a 

rejected takeoff to an unprepared site. A 

CPT provides signals to the Digital 

Engine Control Units (DECU) to 

anticipate power demand. A worn CPT 

can send an erroneous signal to the 

DECU. This condition can cause a 

power split between the two engines 

and a subsequent OEI condition, which 

can result in an emergency landing. 

Accordingly, this proposed AD would 

require initial and recurring inspections 

of the CPTs, and depending on the 

outcome of the inspections, replacing 

the CPT. The proposed actions are 

intended to detect wear of a CPT prior 

to it causing an OEI condition and 

possible emergency landing. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all known relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type designs. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Sikorsky S–76 

Helicopter Alert Service Bulletin (ASB) 

76–73–8, Revision A, dated December 4, 

2015 (ASB 76–73–8A), which specifies 

a one-time inspection of total resistance, 

linearity resistant movement, excitation 

voltage, and differential voltage of the 

CPTs using CPT Text Box P/N 76700– 

40009–042. 

We also reviewed Sikorsky 

Maintenance Manual, SA 4047–76C–2, 

Temporary Revision No. 73–07, dated 

August 17, 2016 (TR 73–07), which 

specifies procedures for removing, 

installing, and adjusting the CPTs, and 

inspections of total resistance, linearity 

resistant movement, excitation voltage, 

and differential voltage of the CPTs. TR 

73–07 also divides the procedures by

Sikorsky Special Service Instructions 

(SSI) No. 76–96, dated August 19, 2016, 

which is not incorporated by reference 

in this proposed AD. 

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. 

Other Related Service Information 

We reviewed Sikorsky S–76 

Helicopter ASB 76–73–8, Basic Issue, 

dated August 21, 2015 (ASB 76–73–8). 

ASB 76–73–8 contains the same 

procedures as ASB 76–73–8A; however, 

ASB 76–73–8A updates Sikorsky’s 

contact information for submitting a 

purchase order. 

We also reviewed Sikorsky SA 4047– 

76C–2–1, Temporary Revision No. 5– 

181, dated August 21, 2015 (TR 5–181); 

Task 5–20–00 of Sikorsky Airworthiness 

Limitations and Inspection 

Requirements, Publication No. SA 

4047–76C–2–1, Revision 24, dated 

December 15, 2015 (Task 5–20–00); and 

Section 73–22–04 of Chapter 73 Engine 

Fuel and Control, of Sikorsky 

Maintenance Manual, SA 4047–76C–2, 

Revision 31, dated December 15, 2015 

(Section 73–22–04). TR 5–181 specifies 

adding CPT inspections referenced in 

Section 73–22–04 to the 300-hour 

inspection checklist contained in Task 

5–20–00. 

We reviewed Sikorksy Safety 

Advisory No. SSA–S76–11–0002, dated 

May 17, 2011. This service information 

provides precautionary instructions to 

minimize hazardous situations that 

might result from an unreliable CPT. 

We reviewed Sikorsky SSI No. 76–96, 

dated August 19, 2016, which specifies 

procedures to modify CPT Test Box 

P/N 76700–40009–042 and re-identify it 

as P/N 76700–40009–043. This one-time 

modification reduces the instructions to 

inspect the CPT and improves the 

inspection accuracy. 

We also reviewed Sikorsky SSI No. 

76–87, dated July 24, 2015, and SSI No. 

76–87A, Revision A, dated August 21, 

2015. These SSIs specify a one-time 

inspection of total resistance, linearity 

resistant movement, excitation voltage, 

and differential voltage of the CPTs 

using CPT Text Box P/N 76700–40009– 

042. 

Proposed AD Requirements 

This proposed AD would require 

initial and recurring inspections of each 

CPT by measuring resistance, linearity 

resistance movement, and differential 

voltage, and depending on the outcome 

of the inspections, replacing the CPT. 

Differences Between This Proposed AD 

and the Service Information 

Sikorsky ASB 76–73–8A and TR 73– 

07 specify using and returning 

Sikorsky’s CPT data sheet to Sikorsky. 

This proposed AD would not require 

using Sikorsky’s CPT data sheet or 

returning a data sheet to Sikorsky. TR 

73–07 specifies adjusting the CPT 

transducers. This proposed AD would 

not require adjusting the CPT 

transducers. TR 73–07 specifies 

returning a failed CPT to Sikorsky. This 

proposed AD would not require 

returning a failed CPT to Sikorsky. 

Interim Action 

We consider this proposed AD to be 

an interim action. The design approval 

holder is currently developing a 

modification that will address the 

unsafe condition identified in this 

proposed AD. Once this modification is 

developed, approved, and available, we 

might consider additional rulemaking. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 90 helicopters of U.S. 

Registry. We estimate that operators 

may incur the following costs in order 

to comply with this AD. Labor costs are 

estimated at $85 per work-hour. The 

inspections would take about 3.75 workhours for an estimated cost of $319 per 

helicopter and $28,710 for the U.S. fleet 

per inspection cycle. Replacing a CPT 

would take about 6 work-hours and 

parts would cost $3,072 for an estimated 

replacement cost of $3,582. 

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, 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.
