The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. steel hub turbine propellers, with any counterweight slug attachment bolts, part number (P/N) B-3386-14H, LFC manufacturing lot 224, installed. This AD requires identifying and removing all counterweight slug attachment bolts, P/N B-3386-14H, LFC manufacturing lot 224, from service and installing serviceable bolts. This AD results from two reports of failure of the bolts that attach the propeller blade counterweight slug, and separation of the counterweight slug which led to propeller vibration and damage to the propeller spinner. We are issuing this AD to prevent separation of the propeller blade counterweight slug, which could lead to injury and damage to the airplane.
You are responsible for having the actions required by this AD performed within 50 flight hours after the effective date of this AD, unless the actions have already been done.
Identify and remove all propeller blade counterweight slug bolts, P/N B-3386-14H, LFC manufacturing lot 224, from service, and install serviceable bolts.
(g) Use paragraphs 3.A.(1) through 3.A.(4)(b) 5 of the Accomplishment Instructions of Hartzell Propeller Inc. ASB No. HC-ASB-61-313, Revision 2, dated March 27, 2009, to do the identification, removals from service, and installations.
For the purpose of this AD, a serviceable propeller blade counterweight slug bolt is a P/N B-3386-14H bolt with an LFC manufacturing lot other than lot 224.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
