14 CFR Part 39 

[Docket No. FAA-2013-0262; Directorate Identifier 2013-NE-13-AD] 

RIN 2120-AA64 

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 model6/5500/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 i 

propeller failure and loss of airplane control. 

DATES: We must receive comments on this proposed AD by [INSERT DATE 60 

DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. 

ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 

and 11.45, by any ofthe following methods: 

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202-493-2251. 

• Mail: U.S. Department of Transportation, Docket Operations, M-30, West 

Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, D 

20590.
