SAIB: NE-08-26R3 of Lycoming four, six, and eight cylinder reciprocating engines with a Teledyne Continental Motors (TCM) Series D2000 and D3000 Dual Magneto (2 magnetos with a single drive)

This Revised Special Airworthiness Information Bulletin (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.

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

SAIB: CE-11-06 Main Landing Gear – Tires and Wheels

This Special Airworthiness Information Bulletin (SAIB) alerts you, registered owners and operators of small airplanes, to follow established safety criteria, guidance, and data when modifying your aircraft with tires that are oversized compared to the original equipment Federal Aviation Administration- (FAA-) approved type design.

Oversized tires have been FAA approved by supplemental type certificates (STC) and field approvals on numerous small aircraft types for an assortment of reasons, such as maintaining ground clearance when installing larger propellers or improving landing performance for unique conditions.

These oversized tires have customarily been referred to as “Tundra” tires.

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

Investigation of a recent accident highlights the need for reminding operators of part 23 certificated airplanes that oversized tire modifications require analysis and substantiation as well as periodic inspections to prevent unsafe conditions.

This SAIB reiterates the criteria to apply when evaluating the use of oversized tires and for determining the appropriate requirements to obtain necessary FAA approval.

FAA-2006-24785 Lycoming Engines Reciprocating Engines

We are superseding an existing airworthiness directive (AD) for certain Lycoming Engines (L)O-360, (L)IO-360, AEIO-360, O-540, IO-540, AEIO-540, (L)TIO-540, IO-580, and IO-720 series reciprocating engines.

That AD currently requires replacing certain crankshafts in the affected engines.

This AD continues to require replacing certain crankshafts, corrects the start date of affected engine models in Lycoming Mandatory Service Bulletin (MSB) No. 569A to the start date in Supplement No. 1 to Lycoming MSB No. 569A, dated May 27, 2009, and includes additional (formerly experimental) IO-390, AEIO-390, and AEIO-580 series engine models having affected crankshafts.

This AD was prompted by Lycoming Engines discovering that the start date of affected engine models in MSB No. 569A is incorrect and the need to include additional engine models having the affected crankshafts.

We are issuing this AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.

FAA-2011-0139 B/E Aerospace, Continuous Flow Passenger Oxygen Mask Assembly

We are adopting a new airworthiness directive (AD) for the products listed above, except for those that are currently affected by similar action through any of five ADs applicable to Boeing products. This AD requires an inspection/records check to determine the manufacturer and part number of the oxygen mask assemblies installed, an inspection to determine the manufacturing date and modification status if certain oxygen mask assemblies are installed, and corrective action for certain oxygen mask assemblies. This AD was prompted by a report that several oxygen mask assemblies with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the oxygen mask assembly from fracturing and separating, which could inhibit oxygen flow to the masks. This condition could consequently result in occupants developing hypoxia following a depressurization event.

FAA-2011-0126 Lycoming Engines and Teledyne Continental Motors (TCM) Turbocharged Reciprocating Engines

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting certain Lycoming and TCM reciprocating engines with certain Hartzell Engine Technologies, LLC (HET) turbochargers installed, and disassembly and cleaning of the turbocharger center housing and rotating assembly (CHRA) cavities of affected turbochargers. This AD was prompted by a turbocharger failure due to machining debris left in the cavities of the CHRA during manufacture. We are issuing this AD to prevent seizure of the turbocharger turbine, which could result in damage to the engine, and smoke in the airplane cabin.
