PART I - INSTRUCTIONS

Introduction:

The National Transportation Safety Board (NTSB) Coding Manual is a source document for codes to be used in the Board's main frame computer for storage and retrieval of information concerning the findings of aviation accidents. This revision of the coding manual contains suggested changes that were received in the Regional Operations and General Aviation Division (AS-20). Procedures are in effect to update the manual on a periodic basis. Suggestions for changes or corrections should be forwarded to the Senior Analyst(s) in AS-20. Suggestions may be forwarded by using the form at the end of this manual or by telephone.

The codes are normally sent to the main frame computer through a network system by using the ADMS program. Entry of codes may be made by the individual investigator by using his (or her) PC or by personnel in AS-20. A computer matrix is provided in the ADMS program for entry of codes. The codes should be entered in the matrix to correspond with the sequence in which they led to the accident/incident.

Computerized findings are published for each accident and incident in a brief format (Brief-of-Accident or Brief-of-Incident). Each brief includes findings, which are identified in a sequence-of-events as occurrences, phases, causes, factors, and/or events. A probable cause statement is also published to provide a narrative presentation of the NTSB findings.

The codes and respective printout data are listed in the coding manual in an alphabetical order, within the respective categories, rather than in a sequential or number order. Printout data is listed in upper-case letters, whereas explanatory notes (that do not print out) are in parenthesis with lower-case wording.

The previous publication of the this manual was in January 1995. Codes that have been added or changed (since the previous publication) are annotated as follows:

General Instructions:

As previously noted, the codes in this manual are intended to be used to describe the sequence-of-events of each accident and/or incident. All entries in the sequence-of-events (and brief narrative) must be substantiated by information that is documented in the Factual Report or is available in other accessible documents or publications.

Multiple occurrences, causes, factors and/or events may be used in each sequence-of-events to describe the findings. Each occurrence is coded separately and a corresponding phase of operation must be entered with each occurrence; as of the date of this publication, only five occurrences can be recorded for each mishap. There must be at least one occurrence and one cause identified with each accident or incident. The occurrences must be chronologically numbered. For accidents with multiple causes, there is no provision to show the magnitude of each cause with respect to the others. Likewise, there is no provision to show the relative magnitude of multiple factors. For retrieval purposes, elements of the probable cause (PC) statement should be coded in the sequence-of-events, if feasible.

The number of findings and the size of the PC statement are limited by the amount of space available on the second page of the computer printout. Depending on the number of occurrences and number of lines used in the probable cause statement, about 15 to 43 causes/factors/events can be listed for any one accident or incident.

The sequence-of-events matrix (see: Sequence-of-Events Worksheet, Part III) contains entry spaces for codes in the following sections:

Each section of the matrix contains columns of spaces. The spaces in the left column of each section are for "subject" codes. The long spaces to the right of the subject spaces are for modifiers/persons. The short spaces in the middle of each section are used to describe whether the subjects are causes or factors by entering "C" or "F" codes. These may be left blank, if the subject is neither a cause nor a factor, but merely an event.

Formerly, the main frame (DEC 10) computer (using System 1022) was programmed to allow entry of restricted information in the data base that would not print out in the briefs. This was accomplished by putting an "X" in the middle space to denote the restricted information. This information was stored in the computer for use as statistical information only. Currently, there is no requirement for entry of restricted data, and the VAX/MV-4 computer (using System 1032) has not been programmed for entry of this information. The data base, however, still contains restricted information that was previously entered via the DEC 10.

Within each section of the matrix, each line entry must be completed in its entirety; i.e., each subject code must be followed by a modifier and/or person code. Sections IA and IB are used to list the primary events/findings that led to the accident or incident. Sections II and III are used to further define or explain a primary event or finding that is listed in Section IA or IB.

Section IA is used to identify the primary non-people-related findings. It contains columns of spaces to enter non-people-related subjects and modifiers. However, a code is available to allowed the modifier to be left blank, if needed. The non-people-related subjects are grouped in the following categories:

Section IB identifies the primary finding(s) that are people related. This section normally contains a subject, modifier, and person, although codes are available for the modifier and person to be left blank. However, the blank code for a person should only be used when no other person code can be supported by the factual report. A blank modifier code is only used in conjunction with a blank person code.

Sections II and III are used for the direct and indirect underlying findings. They are normally coded with a subject and a person (or institution), but codes are available for the person code to be left blank. Any number of underlying findings can be related to a primary finding in Section IA and/or IB. However, underlying findings in Sections II or III should only be used when they are related to a primary finding in Section IA and/or IB.

The computer system was previously programmed so that when more than one finding was entered on the same line, findings in sections/columns to the right would be indented to show a relationship. This feature is no longer available. Print-outs from the codes are now (without indentation), beginning with the first code entered on the left in line one of the matrix followed by those to the right and below.

Mandatory Conventions:

The coding manual is designed to provide a great degree of latitude and flexibility in formulating the findings. However, certain conventions should be followed to logically present some sequences-of-events.

For NTSB retrieval of multiengine aircraft information, the phrase "TOTAL LOSS OF ENGINE POWER" and "PARTIAL LOSS OF ENGINE POWER" are to be used in reference to the specific engine(s) being addressed, rather than to the overall power of the aircraft. Specifically, for a situation involving total loss of power for mechanical reasons in one engine of a multiengine aircraft, the code for that occurrence would be 351 (for "LOSS OF ENGINE POWER(TOTAL) - MECH FAILURE/MALFUNCTION"). Also, codes are provided in the aircraft section to identify the number of engines affected on multiengine aircraft. The following codes are intended for use with multiengine aircraft findings:

For occurrences involving loss of engine power in multiengine aircraft, one of the above codes would normally be used as the first entry (subject) in the sequence-of-events (in Section IA); an exception would be when the number of engines that lost power was unknown. These (subject) codes should be modified by Code 1220 (blank code), so that no modifier will print out. Typically, losses of power in more than one engine would be coded as separate occurrences, except when more than one engine loses power at the same time for the same reason. If the occurrence resulted in all engines losing power (i.e., fuel exhaustion), then Code 16908 (ALL ENGINES) should be used (even if the aircraft had two or three engines, though there are codes for two and three engines).

For example, consider a turbine disk failure of the No. 1 engine of a Boeing 727 that resulted in a total loss of power of that engine; then shortly thereafter, partial loss of power occurred in the No. 2 and No. 3 engines due to a fuel system problem.

In coding this scenario, there would be two occurrences involving loss of power; i.e. the first occurrence would be coded "LOSS OF ENGINE POWER (TOTAL)- MECH FAILURE/MALFUNCTION." The first subject code for this occurrence would be 16905, (ONE ENGINE), which would be modified by Code 1220 (blank space). Of course, additional findings would follow to describe the appropriate cause(s) and/or factor(s).

The second occurrence would be coded "LOSS OF ENGINE POWER (PARTIAL) - MECHANICAL FAILURE/MALF." The first subject code for the second occurrence would be 16906 (TWO ENGINES) followed by Code 1220 (blank space).

For single-engine aircraft accidents/incidents, there is no reason to provide a code for the number of engine, since "one engine" would be obvious.

A progressive loss of power may be considered a single event. For example, a bearing failure may result in a partial loss of power at first, but the power loss could deteriorate until there was a total loss of power. For all practical purposes, this would be one occurrence.

Whenever an occurrence mandates a forced landing, the next occurrence in the sequence-of-events would normally be "FORCED LANDING" (180). The associated phase of operation will often be "EMERGENCY DESCENT/LANDING" (576), but the phase could be "MANEUVERING - TURN TO LANDING AREA (EMERGENCY)" (583), "EMERGENCY LANDING AFTER TAKEOFF" (575), "EMERGENCY LANDING" (574), or "LANDING" (570). Forced landings are often presented with no other findings listed for that occurrence. However, there are some typical findings that are occasionally used with forced landings, if they are appropriate and substantiated; i.e., "EMERGENCY PROCEDURE - NOT FOLLOWED - PILOT IN COMMAND" if and when appropriate, and "AUTOROTATION - PERFORMED - PILOT IN COMMAND" when a helicopter is involved in an autorotation during a forced landing.

Code 502, "STANDING - STARTING ENGINE(S)," is used for hand propping/runaway accidents. The typical convention for coding this situation would be as follows:

For occurrences involving carburetor ice, the sequence-of-events should include the environmental condition and the events leading to the situation as well as listing the cause/factor(s). The following is a typical convention for mechanical loss of power due to carburetor heat control failure and subsequent carburetor ice:

For nonmechanical loss of power due to improper use of the carburetor heat by the pilot:


PART II - DEFINITIONS

ABRUPT MANEUVER: An intentional maneuver that directly results in personal injury or aircraft damage.

ALTITUDE DEVIATION, UNCONTROLLED: For an occurrence in which there is a loss of control that results in a loss or gain in the altitude, but recovery is accomplished (i.e., autopilot malfunction of airliner that results in altitude deviation & injury to unbelted occupant).

COLLECTIVE BIAS: A mechanism, system, or function of a helicopter that automatically adjusts engine power to maintain rotor rpm, when an increase or decrease in collective is made. (The mechanism is also known as a throttle/collective correlator box.)

DITCHING: A planned event in which a flight crew knowingly makes a controlled emergency landing in water. (Excludes float plane landings in normal water landing areas.)

DRAGGED WING, ROTOR, POD, FLOAT, OR TAIL: Use as a first occurrence only, when this results in an aircraft accident or incident during taxi, takeoff, or landing. (Not used in conjunction with a hard landing or after a gear collapse or ground loop/swerve.)

DYNAMIC ROLLOVER: Ground rollover mishap of a helicopter, which results from a cumulative effect of dynamic forces. These forces cause a roll reaction that results in the helicopter exceeding its static rollover angle.

ENGINE TEARAWAY: An occurrence in which one or more engines are torn away from an aircraft, but not due to contact with an external object. (Includes tearaway due to internal damage from foreign object damage.)

FORCED LANDING: An emergency landing involving circumstances in which the pilot does not have the option to selectively choose the time and appropriate location for landing. (See "precautionary landing" for circumstances in which the pilot has the time and option to choose an appropriate landing area.)

GEAR COLLAPSE: Collapse of the landing gear due to mechanical failure other than malfunction of the retracting system. When the landing gear collapses as a result of a hard landing, the gear collapse will be the subsequent (second) occurrence.

FIRE/EXPLOSION: Use as an occurrence for fire, explosion, or heavy smoke occurring in flight, and for aircraft fires occurring on the ground, except those resulting from impact.

GEAR RETRACTION: Retraction of the landing gear (on ground or runway) due to malfunction of the retraction system, or due to inadvertent or premature retraction by the crew. (Gear retraction on takeoff will be coded as gear retraction in the takeoff phase, and will not be recorded as a wheels-up landing. Excludes intentional gear retractions.)

GO-AROUND: A maneuver following an uncompleted approach, which involves transition to a climbing flightpath.

GROUND LOOP: An involuntary uncontrolled (abrupt) turn of an aircraft, while moving along the ground (i.e., ground taxiing or moving on the takeoff or landing run).

GROUND RESONANCE: Dangerous natural vibration of a helicopter on the ground, caused by stiffness and frequency of the landing gear legs, amplifying the primary frequency of the main rotor. (Includes the self-excited vibration of a helicopter, occurring whenever the frequency of oscillation of the blades about the lead-lag hinges of an articulated rotor becomes the same as the natural frequency of the fuselage.)

HARD LANDING: Stalling onto or flying into a runway or other intended landing area with abnormally high vertical speed. For rotorcraft, includes "tail-down" landings and those where the main rotor contacts the tail boom on landing.

HEIGHT/VELOCITY CURVE: Fundamental plot of indicated airspeed against altitude, which is included in the helicopter flight manual; indicates region(s) from which safe autorotative descent is possible, normally assuming zero wind, sea level, and maximum takeoff weight.

HELIPAD: Prepared area (of land, water or structure) designated as a takeoff/landing area for helicopters (no facilities other than markings needed); includes truck or trailer that is routinely used as heliport.

HELIPORT: A facility used for operating, basing, housing, and maintaining helicopters.

IN-FLIGHT ENCOUNTER WITH WEATHER: Weather encountered that is not normal to the intended phase of operation. Use as an occurrence only when it leads to an accident or incident. (Excludes: vortex turbulence and operations in normal crosswind or IFR conditions.)

MISSING AIRCRAFT: For purposes of coding, a missing aircraft is one that is presumed to have crashed, and the location of the crash is unknown. If credible witness(es) or pieces of wreckage can reasonably verify the accident and location, then the aircraft would not be considered as missing.

NOSE DOWN: When an aircraft noses down on the ground, water, or runway without going inverted.

NOSE OVER: When an aircraft goes inverted on the ground, water, or runway, while taxiing or on takeoff or landing.

NOTAR SYSTEM: Helicopter "No Tail Rotor" System. (For McDonnell Douglas Helicopters: consists of an enclosed variable pitch fan driven by the transmission, a circulation control tail boom, direct-jet thruster, and vertical stabilators.)

OCCURRENCE: Distinct major event of relative significance that leads to an accident or incident.

ON-GROUND ENCOUNTER WITH WEATHER: An occurrence involving weather that is not normal to the phase of operation. (Excludes: vortex turbulence, jet/prop blast, and normal IFR or crosswind conditions.)

OVERRUN: The continuation of aircraft movement beyond the end of the runway; i.e., overrunning the intended landing or takeoff area. (Used in takeoff and landing phases.)

PHASE OF OPERATION: The point in aircraft operations during which an occurrence takes place.

PIBAL: Small balloon launched to check wind direction before takeoff of hot air balloon to assist in visualizing ground track relative to anticipated flightpath.

PRECAUTIONARY LANDING: A landing involving a sense of urgency due to an emergency or pending emergency, in which the pilot has the option and time to selectively choose an appropriate landing area.

PROPELLER FAILURE/MALFUNCTION: An occurrence concerning failure or malfunction of a propeller blade, hub, or related part, including separation or overspeeding of a propeller, or failure of a propeller system. (Note: When propeller failure results from engine seizure, crankshaft failure, etc., the occurrence should be coded as an engine failure.)

ROLL OVER: Refers to rotorcraft only. Includes tilting with the main rotor blades striking the ground.

ROTOR FAILURE/MALFUNCTION: An occurrence concerning failure or malfunction of a rotor blade, hub, or related part, including separation or overspeeding of a rotor or failure of the rotor drive system.

SETTLING WITH POWER: A condition of helicopter power settling, in which hover power required exceeds power available, normally resulting from an attempt to hover out of ground effect with insufficient power available to compensate for elevation, temperature, and/or humidity.

UNAPPROVED PART: A part, component, or material that has not been manufactured in accordance with the approval procedures in FAR 21.305 or repaired in accordance with FAR Part 43; does not conform to an approved type design; or does not conform to established industry or U.S. specifications (standard parts). Examples of an unapproved part include, but are not limited to: (1) Counterfeit or fraudulently marked parts, components, or materials; (2) Parts shipped directly to users by a manufacturer, supplier, or distributor who does not hold, or operate under the authority of, a production approval for the part; and (3) Parts that have been maintained or repaired and returned to service by persons or facilities not authorized under FAR Parts 43 or 145.

UNDERSHOOT: A condition that occurs during an approach to landing that results in an inadvertent landing or contact with the ground or an object short of the runway or intended landing area, normally due to misjudgment of distance, speed, and/or altitude on final approach. For IFR approaches, an undershoot will occur only after the field or intended landing area is in sight. An undershoot will always be followed by a subsequent occurrence; i.e., in-flight collision with object or terrain, etc. (Does not include occurrences in which the aircraft could not have reached the intended landing area; i.e. after loss of engine power.)

VORTEX RING STATE: An area of nonuniform and unsteady airflow around a rotating main rotor or tail rotor in which the rotor is affected by an induced velocity of airflow that approaches or exceeds the airflow being produced by the affected rotor. It is characterized by a sudden requirement for increased power and/or rotor pitch when airflow from the affected rotor is forced back through and around the rotor.

WHEELS-UP LANDING: Code as an occurrence when the landing gear is not lowered and locked before contact with the ground/runway during a landing. (Excludes inadvertent retraction on the ground and retractions due to failure or malfunction of the gear assembly and/or retracting mechanism. Includes intentional wheels-up landing and inability to extend the gear due to malfunction of the gear extension system.)

VLOF "Lift-off speed"

VMCG "Minimum control speed on the ground" The minimum speed at which, the critical engine having been made suddenly inoperative at that speed and having been recognized by the pilot, it is possible to maintain control of the airplane with the engine still inoperative, using primary aerodynamic controls alone, and thereafter maintain a straight path parallel to that originally intended.

VMCA "Minimum control speed" The minimum speed at which, when the critical engine is suddenly made inoperative at that speed, it is possible to recover control of the airplane with the engine still inoperative and to maintain it in a straight flight at a speed, either with zero yaw or with an angle of bank not in excess of 5o.

VYSE "Best rate-of-climb single-engine speed"

VXSE "Best angle-of-climb single-engine speed"

VS "Stalling speed" The minimum speed in flight at which the airplane can develop a lift equal to the weight of the airplane.

VSO "The power off stall speed" or minimum steady flight speed in the landing configuration.

VFE "Maximum flap extended speed"

VLO "Maximum landing gear extension/retraction speed"

VLE "Maximum landing gear extended speed"

VA "Design maneuvering speed" The maximum speed for which the aircraft is designed for full abrupt control deflection without incurring structural damage.

VMO "Maximum operating limit speed"

VNE "Never-exceed speed"

VREF "Landing approach speed" The indicated airspeed that the aircraft should be at 50 feet above the landing area in the landing configuration. (1.3 x VSO)

VR "Rotation speed"

Vtoss "Takeoff safety speed" (Category A helicopter)

V1 "Takeoff decision speed" (Formerly denoted as critical engine failure speed.) The speed at which, should the critical engine fail, the pilot could elect to abandon the takeoff or continue.

V2 "Takeoff safety speed" A reference speed obtained after lift-off at which the required one-engine-inoperative climb performance can be achieved.

V2MIN "Minimum takeoff safety speed" (1.15 x VS for two and three engine propeller-driven aircraft or 1.10 x VS for four engine propeller-driven aircraft or 1.10 x VMCA, whichever is greater.)
