Planning Information
The bulletin specifies that certain Hartzell steel hub turbine propeller models are affected, particularly those with B-3386-14H bolts from LFC manufacturing lot 224. It clarifies that bolts from other lots or manufacturers are not affected. Compliance with previous versions of the bulletin exempts certain applications from this revision.
Reason
The bulletin warns that bolt failures have been reported, leading to counterweight slug separation from the propeller, which poses a significant safety risk. The failure was attributed to a manufacturing defect in the bolts from a specific lot.
Compliance
The document mandates a one-time visual inspection of the affected bolts within 50 flight hours of the original issue date (November 17, 2008). It requires immediate quarantine of any affected bolts found in inventory.
Accomplishment Instructions
Instructions for performing on-wing inspections and bolt replacements are provided. The procedures must be carried out by certified personnel, and specific torque values for the bolts are detailed. The document emphasizes that affected bolts must not be reused in any propeller application.
Material Information
The bulletin lists the part number for the affected bolts (B-3386-14H) and specifies the need for stainless steel safety wire for securing the bolts after replacement.
Safety notes
- Bolt failure may result in counterweight slug separation from the propeller, leading to serious injury or death.
- Perform all inspections in accordance with the most recent revision of this Alert Service Bulletin.
