SPECIAL AIRWORTHINESS

INFORMATION BULLETIN SUBJ: Engine Oil SAIB: NE-14-30 Date: October 1, 2014 This is information only. Recommendations aren’t mandatory.

Introduction This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, repair stations, and flight standards district offices of the Eastman Chemical Company (ECC) purchase of British Petroleum (BP) turbine engine oil products. These products are approved for use on certificated aircraft and engines. ECC purchased the manufacturing facilities and approved oil formulations from BP that are utilized to produce these aviation oils. The FAA determined that Eastman Turbo Oils (ETOs) listed in this SAIB are identical to approved BP Turbo Oils (BPTOs). We also determined that airworthiness approvals for use on aircraft, aircraft turbine engines, and accessories associated with BPTOs are applicable to the corresponding ETOs.

At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

Background ECC purchased the BPTO business assets on June 2, 2014. The ECC acquisition included all BPTO assets and facilities. ECC will continue to produce turbine engine oil products at the production plant, using the identical formulations, processes, base stocks, and additives (including the same material sources) as the approved BPTO products. The SAE E34 Qualified Product Group and the Department of the Navy recently approved adding the ETO brand names corresponding to the existing approved BPTO products to the AS5780 and Navy Qualified Products Database (QPD). The BPTO brand names will remain on the AS5780 and Navy QPD for several years to allow time for users to consume current oil stocks.

Recommendation You can use the following ETO products, since they are identical to the corresponding BPTOs. The airworthiness approvals associated with the corresponding BPTO products are applicable to the ETO products when determining acceptability for use on aircraft engines and accessories:
