[Correction] DECOMATIC Titanium Bolts
Summary
EASA Safety Information Bulletin 2020-08 is a correction notice regarding DECOMATIC titanium bolts manufactured between May and December 2013. These bolts, identified by specific part numbers listed in the bulletin, were produced with an improper heat treatment process that may cause hydrogen embrittlement leading to premature failure. The bulletin applies to all aeronautical products using these affected bolts and aims to raise awareness among manufacturers, maintenance organizations, and operators.
What Changed
This document republishes the original Safety Information Bulletin 2020-08 to correct a typographical error in the part number listing in Appendix 1. No new regulatory requirements are introduced; the correction ensures accurate identification of affected DECOMATIC titanium bolts.
Why It Matters
The bulletin is important because hydrogen embrittlement in titanium bolts can compromise the structural integrity of aeronautical products, potentially leading to unsafe conditions. Aviation professionals, including maintenance and production organizations, need to identify and remove these affected parts to maintain airworthiness and safety. Accurate part number information is critical for effective inventory checks and reporting.
What To Do
Maintenance and production organizations should inspect their inventories for the affected DECOMATIC titanium bolts listed in Appendix 1 and scrap any found, including those with unknown manufacturing dates. They should also verify if any affected bolts have been installed on aircraft and report such findings to the relevant Type Certificate or Supplemental Type Certificate holders referencing this bulletin. No mandatory compliance deadline is specified as the bulletin provides information and recommendations only.
