From the EASA Website:
What are the plans of EASA in regards of the guidance relating to components’ Time between overhaul (TBO) extension?
The Decision 2013/025/R of the Executive Director of the Agency of 11 September 2013 "Recommended practice for TBO extension’"was published by EASA in September 2013. Two months later, in December 2013, the ED Decision 2013/034/R cancelled the ED Decision 2013/025/R - "Recommended practice for TBO extension". That was done in reply to implementation difficulties reported by some NAAs. Afterwards EASA has decided to include the guidance related to the extension of the TBO into the framework of the Rulemaking task Part-M GA Task Force (Phase II).
