4 Glossary Teledyne Continental Motors, Inc. A-2. Glossary Term Airworthiness Approval Tag Burning Burr Chafing Crack Critical Service Bulletin Dent Dynamic Seal Elongate Erosion Fretting Galling Grooved Surface Hydraulic Lock Mandatory Service Bulletin FAA Tag that identifies a part or group of parts that has been deemed airworthy by an authorized FAA representative. In reference to the engine valves, indicates roughening or erosion due to high temperature gases escaping past valve faces. In other instances, it indicates drawing of the temper of steel parts to a soft (blue) condition, as a result of overheating, during an absence of lubrication on moving surfaces, such as gear teeth subject to high loading. Sharp or rough projection of metal. Condition caused by a rubbing action between adjacent or contacting parts under light pressure which results in wear. Partial separation of material usually caused by vibration, overloading, internal stresses, improper assembly, or fatigue. Service document based on determination by the product manufacturer to constitute a threat to continued safe operation of an aircraft or to persons or property on the ground unless the owner or operator takes some specific action (inspection, repair, replacement, etc.). Documents in this category are candidates for incorporation into an Airworthiness Directive issued by the FAA. Rounded depressed, pushed-in area on a surface. Cylinder seal that consists of the piston rings to the cylinder wall seal. To stretch out or lengthen. Wearing away of material due to flow, hot gases, grit, or chemicals. Surface erosion caused by slight movement between two parts that are fastened together. Severe chafing or fretting that results in transfer of metal from one part to another; usually caused by slight movement of mated parts that have limited relative motion and are under heavy loads. Shallow channels, wider than scratches and usually smooth resulting from wear affected by concentrated contact stress. Condition where fluid accumulates in the induction system or the cylinder assembly. The liquid restricts the piston from traveling during the compression stroke. Damage to the engine occurs when the other cylinders fire, which forces the piston in the fluid-filled cylinder through the compression stroke. Damage to an engine from hydraulic lock can be extensive due to the extreme stress load and can adversely affect connecting rods, pistons, cylinder assemblies, piston pins, the crankcase, and the crankshaft. Service document relating to known or suspected hazards to safety that have been incorporated in whole or in part into an Airworthiness Directive (AD) issued by the FAA, or have been issued at the direction of the FAA by the manufacturer requiring compliance with an already-issued AD (or an equivalent issued by another country s airworthiness authority).

5 Teledyne Continental Motors, Inc. Glossary Term Nick Peening Pitting Propeller Strike Runout Scoring Service Bulletin Service Information Directive Service Information Letter Spalling Static Seal Technical Standard Order Sharp-sided gouge or depression with a V-shaped bottom. Series of blunt depressions in a surface. Formation of pockets of corrosion products on the surface of a metal. Any incident that requires repair (other than minor dressing of the blade) to a propeller blade. Either the propeller strikes an object or an object strikes the propeller and causing a propeller imbalance. Propeller strikes are serious because they can result in engine failure. Even if the propeller still continues to rotate, other components critical to engine operation may be damaged. Eccentricity or wobble of a rotating part; eccentricity of two bored holes or two shaft diameters; a hole or bushing out of square with a flat surface. Runout is usually measured with a dial indicator, and limits stated indicate full deflection of indicator needle in one revolution of part or indicator support. Deep grooves in a surface caused by abrasion from fine hard particles wedged between moving surfaces, as in a bearing and journal, or caused by galling when a moving part is not supplied with lubricant. Service document that contains information considered by the product manufacturer to constitute a substantial improvement to the inherent safety of an aircraft or component of an aircraft; also includes updates of instructions for continued airworthiness. Service document that contains information determined by the manufacturer to be of value to an owner/operator in the use of a product by enhancing safety, maintenance, or economy. Service information communiqué that may be of use to the owner/operator or maintainer of the aircraft. Distress to a loaded surface where chips of the hardened surface are broken out. Vital seal in the engine cylinder that consists of valve-to-valve seat seals, spark plug-to-spark plug port seals, and cylinder head-to-barrel seal FAA-designated number and identification mark indicating that the part or appliance meets applicable design standards and was manufactured in accordance with the requirements of FAR 21 Subpart O.
