Recommendations aren’t mandatory. Introduction This Revised Special Airworthiness Information Bulletin clarifies information (see revision marks below) previously published in SAIB NE-06-31, February 27, 2006, and advises you, owners and operators of Lycoming Engines (Lycoming) O-320-H, O- 360-E, LO-360-E, TO-360-E, LTO-360-E series engines of the following approval of an alternative method of compliance (AMOC) to the requirements of Airworthiness Directive (AD) 80-04-03 R2. All other information remains the same. We have determined that the anti-wear additive contained in the engine lubricating oils listed in Table 1 of this SAIB are the same as Lycoming additive LW-16702 and therefore meet the requirements of Lycoming Service Bulletin 446B, 446C, and 446D. We have approved engine oil change to these oil brands as an AMOC to the requirements of AD 80-04-03 R2, paragraph b.1, with the limitations described below. Background These approved oils contain an additive that is identical to Lycoming’s additive LW-16702, which AD 80-04-03 R2 requires to be added to certain O-360 engine models at each 50-hour oil service interval. We determined that the use of engine lubricating oils listed in Table 1 provide the necessary anti-wear protection at engine start-up and therefore satisfies the intent of the AD. We’ve listed the nine approved additized oils in Table 1.

Use of this AMOC is not mandatory, however, if you elect to use any of the oils listed in Table 1 of this SAIB, or any of the other approved additized oils when complying with AD 80-04-03 R2, the following limitations are applicable: • If you elect to use approved additized oil at the 50-hour oil service interval, we require that you use the same brand and formula additized oil for any makeup oil additions performed during the service interval. • If the same brand and formula approved additized oil is unavailable for make-up, a maximum of 2 quarts of a Lycomingapproved oil listed in Lycoming Service Instruction No. 1014M can be added between 50-hour oil service intervals. • If you add more than 2 quarts of a Lycoming-approved oil listed in Lycoming Service Instruction No. 1014M during the 50-hour oil service interval, then we require that you add Textron Lycoming additive LW-16702. • If you extend the oil service interval beyond 50 hours, we require that you add Textron Lycoming additive LW-16702 at 50 hours to maintain compliance with the AD. • Use only additized oil from containers that have been marked with a statement identifying it as having been approved as an AMOC to the requirements of AD 80-04-03 R2, paragraph b.1.
