14 CFR Part 39 

[Docket No. FAA-2013-0130; Directorate Identifier 2013-NE-07-AD] 

RIN 2120-AA64 

Airworthiness Directives; Hartzell Propeller, Inc. Propellers 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking (NPRM). 

SUMMARY: We propose to adopt a new airworthiness directive (AD) for Hartzell 

Propeller, Inc. propeller models HC-(1 , D)2(X, V, MV)20-7, HC-(1, D)2(X, V, MV)20-8 

and HC-(1, D)3(X, V, MV)20-8. This proposed AD was prompted by failures ofthe 

propeller hydraulic bladder diaphragm and resulting engine oil leak. This proposed AD 

would require replacement of the propeller hydraulic bladder diaphragm. We are 

proposing this AD to prevent propeller hydraulic bladder diaphragm rupture, loss of 

engine oil, damage to the engine, and ~loss of the airplane. 

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.
