EASA SIB NE-14-30: Eastman Chemical Company (ECC) purchase of British Petroleum (BP) Turbine Engine Oil Products

What to do

Operators and maintenance personnel should accept Eastman Turbo Oil products listed in the bulletin as equivalent to the corresponding BP Turbo Oils for use on certificated aircraft engines and accessories. They should continue to use existing BPTO stocks while transitioning to ETO products as needed. No immediate compliance deadline is specified, but users should monitor oil stock consumption and update documentation accordingly.

Summary

The Special Airworthiness Information Bulletin SAIB: NE-14-30 issued by the FAA on October 1, 2014, informs aviation stakeholders about the Eastman Chemical Company (ECC) purchase of British Petroleum (BP) turbine engine oil products. The bulletin confirms that Eastman Turbo Oils (ETOs) are identical to the approved BP Turbo Oils (BPTOs) and are approved for use on certificated aircraft and engines. This applies to turbine engines and accessories using these oils.

What changed

This bulletin announces that ECC acquired BP's turbine engine oil manufacturing facilities and approved formulations, continuing production under the Eastman Turbo Oil brand with identical specifications. The FAA recognizes that airworthiness approvals for BPTOs apply equally to the corresponding ETO products. The BPTO brand names will remain listed alongside ETOs in qualification databases for a transition period.

Why it matters

This information is important for operators, maintenance organizations, and compliance teams to ensure continued use of approved turbine engine oils without interruption or additional certification requirements. It clarifies that switching to Eastman Turbo Oils does not affect airworthiness approvals, supporting operational continuity and regulatory compliance. It also helps manage inventory and procurement decisions during the brand transition.
