AD: Hartzell

AD NUMBER: 2007-24-14
MANUFACTURER: Hartzell
SUBJECT: Airworthiness Directive 2007-24-14
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. Model HC-5N-3( ), HC-E5N-3( )(L), and HC-E5B-5( ) propellers.

This AD requires a one time eddy current inspection of the propeller hub mounting bolt holes and replacement of the propeller hub if cracked.

This AD results from the discovery of a five-bladed propeller hub with a large crack on the mounting flange of the hub.

We are issuing this AD to prevent propeller hub failure, blade separation, damage to the airplane, and possible loss of airplane control.
