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 27 March 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. Note 2: FAA AD 2009-10-14 Amdt 39-15910 dated 8 May 2009 refers. Compliance: Within 50 flight hours after the effective date of this AD, unless the actions have already been done. This Airworthiness Directive becomes effective on 30 July 2009. Background: 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. Investigation by Hartzell Propeller Inc. revealed that the bolts failed due to a bolt manufacturing defect. The issuing of this AD is intended to prevent separation of the propeller blade counterweight slug, which could lead to injury and damage to the aeroplane.
