Lycoming Engines - Approved Lubricating Oils - AMOC to FAA AD 80-04-03R2
Summary
Lycoming Engines - Approved Lubricating Oils - AMOC to FAA AD 80-04-03R2 is a Special Airworthiness Information Bulletin that addresses approved lubricating oils for Lycoming O-320-H, O-360-E, LO-360-E, TO-360-E, and LTO-360-E series engines. It updates the names of certain approved additized oils and adds a new oil to the approved list. The bulletin clarifies compliance options for engine oil additives as an alternative method of compliance (AMOC) to FAA Airworthiness Directive 80-04-03 R2.
What Changed
The bulletin changes the name of Phillips 66 Type 100 AW oil to Phillips 66 Victory Aviation Oil 100 AW and adds Phillips 66 Victory Aviation Oil AW 20W-50AW to the approved oils list. It also includes a note with contact information for obtaining additional AMOCs related to engine lubricating oils. The list of 15 approved additized oils as AMOCs to AD 80-04-03 R2 paragraph b.1 is updated accordingly.
Why It Matters
This bulletin matters because it provides operators and maintenance personnel with updated information on approved engine lubricating oils that meet FAA AD 80-04-03 R2 requirements for anti-wear additive protection. Using these approved oils ensures compliance with FAA regulations and maintains engine protection during start-up and operation. It also clarifies limitations and procedures for oil changes and additive replenishment, helping to avoid unsafe conditions and regulatory non-compliance.
What To Do
Operators of affected Lycoming engines should use only the approved additized oils listed in the bulletin or comply with the additive replenishment requirements of AD 80-04-03 R2. They must maintain the same brand and formula of oil between 50-hour service intervals or follow specified procedures if switching oils. If extending oil change intervals, the Textron Lycoming additive LW-16702 must be added to maintain compliance. Contact the FAA New York Aircraft Certification Office for alternative compliance methods if needed.
