Airworthiness Directives; Hamilton 

Standard Division and Hamilton 

Sundstrand Corporation Propellers 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Hamilton Standard Division model 6/ 

5500/F and 24PF and Hamilton 

Sundstrand Corporation model 14RF, 

14SF, 247F, and 568F series propellers. 

This proposed AD was prompted by the 

amount of corrosion detected during 

major inspections (MIs). This proposed 

AD would require incorporating 

inspections, based on a calendar time, 

into the propeller maintenance 

schedule. We are proposing this AD to 

prevent corrosion that could result in 

propeller failure and loss of airplane 

control. 

DATES: We must receive comments on 

this proposed AD by July 22, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2013–0262; Directorate Identifier 2013– 

NE–13–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD 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 proposed AD. 

Discussion 

We received reports about increased 

corrosion detected during MIs of 

Hamilton Standard Division model 6/ 

5500/F and 24PF and Hamilton 

Sundstrand Corporation model 14RF, 

14SF, 247F, and 568F series propellers. 

The propellers were found to 

accumulate fewer flight hours per year 

as they aged. The longer time between 

MIs contributes to an increased 

potential for corrosion to accumulate to 

critical limits. Hamilton Sundstrand 

developed, and we approved, six 

Airworthiness Limitations Sections 

(ALSs) of the applicable maintenance 

manuals to date. Each ALS establishes 

the new compliance times for MIs of the 

blades and hubs by adding a calendar 

time limit for the inspection. This 

condition, if not corrected, could result 

in propeller failure and loss of airplane 

control. 

Relevant Service Information 

We reviewed the Hamilton 

Sundstrand ALS in Maintenance 

Manual P5185, Revision 13, dated 

December 13, 2011; P5206, Revision 9, 

dated February 22, 2013; P5186, 

Revision 12, dated January 20, 2012; 

P5207, Revision 2, dated June 28, 2012; 

P5188, Revision 10, dated January 14, 

2013; and P5189, Revision 8, dated 

March 26, 2013. The ALS in these 

maintenance manuals lists the MIs for 

the associated propellers and prescribe 

a seven-year calendar time limit interval 

for MI of propeller blades and hubs. 

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 

incorporating a seven-year calendar 

time limit, between MIs of propeller 

blades and hubs, into the propeller 

maintenance schedule, within 45 days 

after the effective date of the AD. 

Differences Between the Proposed AD 

and the Service Information 

The updated maintenance manuals 

require that an MI of the blades and 

hubs be performed at the published 

flight hours or no later than seven years 

since the date since installation (DSI). 

The DSI will begin at initial installation 

after the most recent MI or initial 

installation after production. This 

proposed AD would require that the 

Hamilton Sunstrand propeller models, 

with an approved update to the 

maintenance manual ALS, have 45 days 

after the effective date of the AD to 

incorporate the seven-year calendar 

time limit. These models/manuals are: 

14RF–9/P5186, 14RF–21/P5189, 14SF– 

5/P5188, 14SF–7/P5185, 14SF–11E/ 

P5207, and 568F–1/P5206. This 

proposed AD would also require that 

the Hamilton Sundstrand and Hamilton 

Standard propeller models, without 

approved updates to the maintenance 

manual ALS, incorporate the seven-year 

calendar time limit into the propeller 

maintenance schedule within one year 

after the effective date of the AD. These 

models/manuals are: Hamilton Standard 

24PF/61–12–01 and 6/5500/F/P5190, 

and Hamilton Sundstrand 14RF–19/ 

P5199, 14RF–37/P5209, 14SF–11/ 

P5196, 14SF–15/P5197, 14SF–23/P5197, 

14SF–17/P5198, 14SF–19/P5198, 247F– 

1/P4202, 247F–1E/P5204, 247F–3/ 

P5205, 568F–1/P5214, 568F–5/P5203, 

and 568F–7/P5211. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 1,044 propeller/hub 

combinations installed on airplanes of 

U.S. registry. We also estimate that it 

would take about 160 hours per 

propeller to perform one MI. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

the proposed AD on U.S. operators to be 

$14,198,400. 

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 to the extent that it justifies 

making a regulatory distinction, and 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 100 / Thursday, May 23, 2013 / Proposed Rules 30797 

(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.
