AC 43 - 204 8/14/97 Appendix H
ENGINE VISUAL INSPECTION GLOSSARY (Courtesy of Pratt & Whitney) GLOSSARY OF TERMS: The following defines terms used in this Master and other VIS's.
Abrasion: A rubbing away of coating material which may or may not expose base metal.
Back-To-Back Imperfections: Imperfections on the opposite faces of a specific wall (or weld) which normally are opposite each other (see Figure H-
1). This condition is considered evidence of a single thru-wall imperfection.
If it is obvious that discontinuities on opposite faces are caused by the same defect. Even though offset, this condition is considered back-to-back (see Figure H-2).
Figure H-1. Single Thru-Wall Figure H-2. Back-To-Back Bellmouth: Taper condition formed on ID of a hole at the opposite end of the hole from which a punch or blanking die enters.
Blending: An operation which removes an irregularity from a surface, resulting in a shallow, smooth depression.
Blister: A localized lifting of coating, plating, fiberglass, or paint, appearing as a bulge that may break when probed.
Bottomed Imperfection: Pit, cavity or hole in which the bottom can be seen.
Braze Crack: Linear fracture of the braze surface.
Braze Fillet: Braze in a joint creating a smooth transition between the details being joined.
Braze Joint: Area between details to be joined by brazing.
Braze Porosity: A group of closely-spaced, small voids (internal pores) in the braze joint or fillet open to the braze surface.
rage 2
8/14/97 A0 43-204 Appendix H Braze Rippling: A condition of the braze surface characterized by unevenness and irregular appearance with peaks and valleys that are gradual in nature, like ripples on a pond.
Braze Void: Unfilled space in braze material in which a bottom is visible.
Broach Mark: A straight depressed imperfection without tears, caused by the broaching operation (See Tool Mark).
Burate; hay chirain seatsuling from pabbin gagainst a hard, smooth Burnishing: Mechanical smoothing of a surface, usually by rubbing.
Burn Marks: Localized indication of excessive heating (e.g., blue to blueblack discoloration) due to excessive dwell time of a tool at that location, or electrical arcing due to improper contact between an electrode and the part.
Burn Out: Electro-chemical machining erosion beyond the desired feature profile.
Burr: A fragment of metal which remains attached to the surface after a machining or riveting operation.
Burst: Cracks caused by rupture extending outward from a central point.
Chain Porosity: Porosity in linear alignment.
Chatter Mark: Recurring undulations or irregularities that result from vibratory interactions of the tool and a typical machined surface.
Chips or Chipping: Discrete particles of a coating which have been removed by mechanical means.
Clearly Separated: Imperfections which are not touching when viewed with the unaided eye.
Cluster: Two or more imperfections, clearly separated, which can be contained within a circle of the maximum diameter allowed by the assigned standard. A cluster, or group of clusters which can be contained within the allowed circle shall be counted as one imperfection.
Cold Shut: Intermittent or continuous lines caused by unused material.
Corrosion: Surface is pitted and discolored, caused by unwanted chemical or electrochemical action.
AC 43-204 8/14/97 Appendix H Crack: Linear imperfection in the form of a narrow break or fissure of the surface.
Crater: A depression at the termination of a weld bead.
Crazing: A network of minute cracks appearing in the coating of coated parts.
Delamination: A separation of the layers in a layered material.
Dent: A surface depression normally having rounded edges, corners, and bottom, caused by the impact of some object.
Depressed Imperfection: Imperfection below the general surface of the part; may have either smooth or irregular (sharp) edges or bottom (See Dent or Pit).
Die Break or Breakway: A rough surface caused by breaking away of metal by a punch or blade during a blanking or shearing operation.
Draw Mark: Linear, trough-like grooves which result from the action of die imperfections or foreign material on the drawn material.
Dross: Linear imperfections or imperfections in the form of branching or irregular patterns, caused by impurities or oxides in a cast material.
Erosion: The carrying away of material by the flow of gases, fluids or solids.
Excess Braze: Braze material beyond the joint fillet; sometimes referred to as a run, streak or flash.
Fissure: Linear imperfection in the form of a narrow separation of surface material.
Flaking: Raised areas of coating or plating on a coated or plated part, indicative of poor bonding.
Foreign Material: Any solid or liquid material not integral to a part.
Such material may or may not be adherent to a surface or passage.
Forging Mark: Ridges or grooves on the external surface of a part caused by foreign material or irregularities on the forming die.
Formed Depression: A change in surface level caused by mismatch of adjoining die segments.
Appendix H Fretting Corrosion: A rapid oxidation of surfaces caused by movement of closely fitted parts. It is characterized by surfaces exhibiting colors ranging from black to brick red, depending upon severity and/or time of exposure to fretting corrosion.
Fusion Line: Interface of the weld bead and parent metal.
Fusion Zone: The weld bead formed by the melting of filler metal and parent metal, or of parent metal only.
Galling: An advanced case of fretting corrosion where there is transfer of material from one to the other of closely fitted surfaces, causing damage to both surfaces.
Gas Path: Engine airstream area.
Gouge: Relatively wide trough-like depression caused by tearing away of the surface by another object.
Grinding: An operation that removes material by the use of an abrasive material to produce a predetermined size.
Groove: A narrow cut in a surface.
Heat Affected Zone: The zone on each side of the weld bead on both the weld deposit and melt thru sides, when applicable. The width of the heataffected zone shall be one half the width of the weld bead. See Figure H-3.
