A-2. Glossary

Term Definition

AirworthinessApproval Tag

FAA Tag 8130-3 that identifies a part or group of parts that has been deemedairworthy by an authorized FAA representative.

Burning In reference to the engine valves, indicates roughening or erosion due to hightemperature gases escaping past valve faces. In other instances, it indicatesdrawing 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.

Burr Sharp or rough projection of metal.

Chafing Condition caused by a rubbing action between adjacent or contacting parts under light pressure which results in wear.

Crack Partial separation of material usually caused by vibration, overloading, internalstresses, improper assembly, or fatigue.

Critical ServiceBulletin

Service document based on determination by the product manufacturer toconstitute 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 arecandidates for incorporation into an Airworthiness Directive issued by the FAA.

Dent Rounded depressed, pushed-in area on a surface.

Dynamic Seal Cylinder seal that consists of the piston rings to the cylinder wall seal.

Elongate To stretch out or lengthen.

Erosion Wearing away of material due to flow, hot gases, grit, or chemicals.

Fretting Surface erosion caused by slight movement between two parts that are fastenedtogether.

Galling Severe chafing or fretting that results in transfer of metal from one part toanother; usually caused by slight movement of mated parts that have limitedrelative motion and are under heavy loads.

Grooved Surface Shallow channels, wider than scratches and usually smooth resulting from wear affected by concentrated contact stress.

Hydraulic Lock Condition where fluid accumulates in the induction system or the cylinder assembly. The liquid restricts the piston from traveling during the compressionstroke. Damage to the engine occurs when the other cylinders fire, which forces

the piston in the fluid-filled cylinder through the compression stroke. Damage toan engine from hydraulic lock can be extensive due to the extreme stress loadand can adversely affect connecting rods, pistons, cylinder assemblies, pistonpins, the crankcase, and the crankshaft.

Mandatory ServiceBulletin

Service document relating to known or suspected hazards to safety that havebeen incorporated in whole or in part into an Airworthiness Directive (AD) issuedby 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 byanother country’s airworthiness authority).

Term Definition

Nick Sharp-sided gouge or depression with a V-shaped bottom.

Peening Series of blunt depressions in a surface.

Pitting Formation of pockets of corrosion products on the surface of a metal.

Propeller Strike Any incident that requires repair (other than minor dressing of the blade) to apropeller blade. Either the propeller strikes an object or an object strikes thepropeller and causing a propeller imbalance. Propeller strikes are seriousbecause they can result in engine failure. Even if the propeller still continues torotate, other components critical to engine operation may be damaged.

Runout Eccentricity or wobble of a rotating part; eccentricity of two bored holes or twoshaft diameters; a hole or bushing out of square with a flat surface. Runout isusually measured with a dial indicator, and limits stated indicate full deflection of indicator needle in one revolution of part or indicator support.

Scoring Deep grooves in a surface caused by abrasion from fine hard particles wedgedbetween moving surfaces, as in a bearing and journal, or caused by galling whena moving part is not supplied with lubricant.

Service Bulletin Service document that contains information considered by the productmanufacturer to constitute a substantial improvement to the inherent safety of anaircraft or component of an aircraft; also includes updates of instructions for continued airworthiness.

Service InformationDirective

Service document that contains information determined by the manufacturer to beof value to an owner/operator in the use of a product by enhancing safety,maintenance, or economy.

Service InformationLetter

Service information communiqué that may be of use to the owner/operator or maintainer of the aircraft.

Spalling Distress to a loaded surface where chips of the hardened surface are broken out.

Static Seal Vital seal in the engine cylinder that consists of valve-to-valve seat seals, sparkplug-to-spark plug port seals, and cylinder head-to-barrel seal

Technical StandardOrder

FAA-designated number and identification mark indicating that the part or appliance meets applicable design standards and was manufactured inaccordance with the requirements of FAR 21 Subpart O.
