Special Bulletin on Cylinder Mounting Studs for Lycoming Engines

Monday, March 31st, 2014

This Special Airworthiness Information Bulletin NE-14-13 (SAIB) alerts you, owners, operators, and certificated repair facilities of Lycoming Engines of the possible failure of engine thru-studs, and/or cylinder mounting studs. 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. FAA Recommendations: 1. Inspect cylinder studs and thru-studs, for corrosion pits and missing cadmium plating. 2. Follow the cylinder installation instructions in the Lycoming overhaul manual or Lycoming Service Instruction No. 1029D. 3. Use Lycoming special tools, or their equivalent, to torque the cylinder nuts. 4. When using the special wrenches to torque cylinder nuts, ensure the wrenches do not contact the cylinder or other parts of the engine. Wrench contact can result in a correct torque indicated by the torque wrench, but the actual torque applied to the nut, and the clamping force, will be lower than required. 5. When accessible, inspect the crankcase main bearing mating surfaces for fretting. Lycoming has advised that no fretting is allowed. pdf icon NE-14-13.pdf

FAA Bulletin on Lycoming LO360, O360, TO360, LTO360 and O320 Engines

Thursday, October 20th, 2011

This Revised Special Airworthiness Information Bulletin NE-06-31R5 alerts 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 that the name of one of the approved additized lubricating oils listed in Table 1 of this SAIB was changed. ConocoPhillips changed the name of Phillips 66 Type 100 AW to Phillips 66 Victory Aviation Oil 100 AW and we changed the name in Table 1 of this SAIB. The oils listed in Table 1 of this SAIB are approved as AMOCs to the requirements of airworthiness directive (AD) 80-04-03 R2, paragraph b.1. All other information remains the same.

FAA Bulletin Update on Magneto Distributor for Lycoming Engines

Friday, April 1st, 2011

Revised Special Airworthiness Information Bulletin NE-08-26R3 (SAIB) alerts you, owners, operators, and certificated repair facilities of Lycoming four, six, and eight cylinder reciprocating engines with a Teledyne Continental Motors (TCM) (formerly Bendix) Series D2000 and D3000 Dual Magneto (2 magnetos with a single drive), of the possibility for the magneto to separate from the engine. Several conditions identified could result in separation of the magneto from the engine, which will result in the loss of power. These engines can be identified by the letter “D” in the 4th or 5th character in the engine model’s suffix. This revision updates the Lycoming Service Instruction (SI) No. from 1508B to SI 1508C. All other information remains the same.

Most of the problems have occurred in Lycoming IO-360-A1B6D and IO-360-A3B6D engines installed on Mooney M20J-201 and Cessna 177RG airplanes, although the potential for magneto separation exists on any engine with a TCM Dual Magneto installed.
