Part Failures

Record and track component failures for reliability analysis. Each failure record captures the part, failure type, hours and cycles at failure, affected aircraft, corrective action taken, and mean time between failures (MTBF). This data feeds into part reliability reports and helps identify recurring failure patterns across the fleet.

Part Failures list showing part numbers, descriptions, serial numbers, failure type badges, failure date, hours at failure, cycles at failure, aircraft reg, and MTBF
2Filter & Columns
ColumnDescription
Part NumberThe failed part (links to detail).
DescriptionPart description from the master.
Serial NumberSerial of the failed unit (if serialised).
Failure TypeBadge: Mechanical, Electrical, Fatigue, Corrosion, Wear, Other.
Failure DateWhen the failure occurred.
Hours at FailureComponent hours at the time of failure.
Cycles at FailureComponent cycles at the time of failure.
Aircraft RegAircraft on which the failure occurred.
MTBFMean time between failures (hours).
Filter by Failure Type to identify recurring patterns. The search box matches part number, serial number, description, and aircraft registration.

FieldRequiredDescription
PartYesSelect the failed part from the dropdown.
Failure TypeYesMechanical, Electrical, Fatigue, Corrosion, Wear, or Other.
Failure DateYesDate the failure was discovered (defaults to today).
Part Failure form with part selector, failure type, failure date, serial number, aircraft reg, hours at failure, cycles, MTBF, reported by, description, and action taken fields
4Failure Details
FieldRequiredDescription
Serial NumberNoSerial of the failed component.
Aircraft RegNoRegistration of the aircraft (e.g. VT-ABC).
Hours at FailureNoComponent flight hours at failure (e.g. 4523.5).
Cycles at FailureNoComponent flight cycles at failure.
MTBFNoMean time between failures in hours.
Reported ByNoName of person who reported the failure.
DescriptionNoDetailed description of the failure mode and symptoms.
Action TakenNoCorrective action performed (e.g. “replaced with P/N ABC-456”).
While most fields are optional, recording serial number, hours at failure, and description is strongly recommended for meaningful reliability analysis.

Click Record Failure to save. Part failures are log-only records — there is no workflow or status progression.

Part failure records feed into the Part Reliability report, which shows failure rates, MTBF trends, and top failing components across the fleet.

6Failure Types
TypeDescriptionCommon Examples
MechanicalPhysical/structural failure.Bearing seizure, gear tooth breakage, shaft fracture.
ElectricalElectrical or electronic failure.Wiring chafe, relay failure, connector corrosion.
FatigueCyclic stress failure over time.Crack propagation, metal fatigue, stress fractures.
CorrosionMaterial degradation from environment.Pitting, exfoliation, filiform, intergranular.
WearGradual material loss from use.Brake pad wear, bushing erosion, seal degradation.
OtherFailure not covered by above categories.Foreign object damage, operator error, manufacturing defect.
