33 cards. Read the term and the definition here. The deck at the top of this page is optional.

Type Certificate

An FAA approval certifying that a product's design meets the applicable airworthiness standards. It defines the approved type design against which conformity of each produced aircraft is judged.

Supplemental Type Certificate

An approval of a major design change to a type-certified product. The STC holder owns and controls the approved data for that change.

Airworthiness Directive

A mandatory rule issued under 14 CFR Part 39 requiring corrective action on affected aircraft. Compliance is required unless an alternative method of compliance is approved.

Preventive Maintenance Scope

Limited to the items listed in Part 43 Appendix A paragraph (c). It may be performed by a certificated pilot or mechanic on aircraft not operated under Parts 121, 129, or 135.

Major Alteration Definition

An alteration that might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other airworthiness qualities. Major repairs are judged by the same standard.

Repair Station Manuals

A Part 145 repair station must maintain a repair station manual and a quality control manual. Both must be current and consistent with each other and with the regulation.

Accountable Manager

The Part 145 person with corporate authority ensuring all maintenance, preventive maintenance, and alterations can be financed and performed to the required standard.

Continuous Airworthiness Maintenance Program

A Part 121 operator's FAA-approved program derived from its maintenance manual. It defines scheduled and unscheduled maintenance tasks, intervals, and responsibilities.

Inspection Authorization Privileges

An IA holder may approve for return to service only work within IA scope and must personally inspect that work before signing the approval.

Contract Maintenance Oversight

A contract maintenance provider working for a Part 121 operator must perform under the operator's continuous airworthiness maintenance program and be listed in the operator's manual.

Reliability Program Alert Level

A threshold set for a monitored parameter. Exceeding it triggers investigation and corrective action, and supports adjustment of maintenance intervals based on statistical analysis.

MSG-3 Task Categories

Tasks classified as lubrication or servicing, operational or visual checks, inspection or functional checks, and restoration, applied to systems, structures, and zonal areas.

Maintenance Review Board Report

Establishes initial minimum scheduled maintenance intervals for an aircraft type. An operator's approved program must be at least as stringent as the MRB report.

Hard-Time versus On-Condition

Hard-time items are removed or overhauled at a fixed limit regardless of condition. On-condition items are inspected at intervals and may continue in service if within limits.

MEL Rectification Intervals

Deferred items are tracked against MEL or CDL category intervals, designated A, B, C, or D, which set the maximum allowable time before rectification.

Principal Structural Element

A structural element that contributes significantly to carrying flight, ground, or pressurization loads and whose failure could reduce structural integrity.

Fail-Safe Design

A design approach assuming a principal structural element can fail while remaining structure carries limit load until the failure is found by inspection.

Damage Tolerance

The ability of structure to sustain design loads in the presence of fatigue, corrosion, or accidental damage until that damage is detected and repaired.

Outflow Valve Function

Modulates cabin discharge air to control cabin pressure differential and rate of change. Pressurization safety depends on this regulation and on relief valves.

Magnetic Particle Inspection

Detects surface and near-surface discontinuities in ferromagnetic materials only. It cannot be used on nonmagnetic materials such as aluminum or austenitic stainless steel.

Eddy Current Inspection

Detects surface and near-surface cracks in conductive materials, including around fastener holes. It uses electromagnetic induction rather than a couplant.

Ultrasonic Inspection

Detects internal discontinuities and measures material thickness. It requires a couplant and knowledge of the material's sound velocity for interpretation.

Functional versus Operational Check

A functional check verifies an item operates within specified limits at the time of the check. An operational check verifies it performs its intended function.

Approved Data for Major Repair

Major repairs require approved data such as an STC, DER-approved repair, or structural repair manual data designated as approved. Minor repairs may use acceptable data.

FAA Form 337 Purpose

Records major repairs and major alterations. A copy goes to the aircraft owner and, where required, is filed with the FAA.

Progressive Inspection Approval

A progressive inspection program must be FAA approved and must cover the same scope as the original inspection program over the complete cycle.

Maintenance Record Entry Content

Must describe the work performed and the completion date, and include the signature and certificate number of the person approving the work for return to service.

AD Compliance Record

Must identify the AD number and revision, the method of compliance, and the compliance date, and must be retained with the aircraft records.

Life-Limited Part Records

Must document total cycles and hours accumulated and must accompany the part when it is transferred to another aircraft or owner.

SMS Four Components

Safety policy, safety risk management, safety assurance, and safety promotion. Together they form the framework for managing safety risk in an organization.

SHEL Model

Describes interfaces among software, hardware, environment, and liveware (people). Mismatches at these interfaces are recognized sources of human error.

Just Culture

Distinguishes human error from at-risk and reckless behavior, applying corrective action proportionate to the behavior rather than punishing honest error.

Safety Risk Matrix

Rates severity from negligible to catastrophic and likelihood from improbable to frequent, producing a risk index used to prioritize hazard mitigation.
