Continuous Airworthiness Maintenance Program Requirements

Continuous Airworthiness Maintenance Program requirements apply to specific categories of FAA-regulated operators and, at their core, oblige each covered operator to build a written program containing ten defined elements, staff it with qualified management personnel, document it through an approved manual and operations specifications, and win FAA authorization through a structured multi-phase certification process. The program is not a periodic inspection checklist. It is a closed-loop maintenance system the operator must run and continuously verify for the entire service life of every aircraft on the certificate.

Who Must Run a CAMP

The requirement is triggered by the operating rule and the aircraft, not by choice. All domestic, flag, and supplemental air carriers under 14 CFR Part 121 must develop and follow a CAMP regardless of fleet size or aircraft type. Part 121 operators conducting Extended Operations with two-engine airplanes carry an added layer: a separate ETOPS continuous airworthiness maintenance program for each airplane-engine combination, authorized through their operations specifications.¹

Under 14 CFR Part 135, the trigger is aircraft size. Commuter and on-demand operators flying aircraft type-certificated for ten or more passenger seats, excluding pilot seats, must follow the maintenance program in sections 135.415 through 135.443, which mirrors the Part 121 CAMP structure.² Part 135 operators flying aircraft with nine or fewer passenger seats fall under an Approved Aircraft Inspection Program instead, which is an inspection program rather than the broader inspection-and-maintenance structure that defines a CAMP.³

Part 125 applies to U.S.-registered civil airplanes seating 20 or more passengers or with a maximum payload capacity of 6,000 pounds or more when common carriage is not involved. These operators maintain their aircraft under programs meeting the FAA’s airworthiness standards, though the regulatory structure differs somewhat from Part 121.⁴

Fractional ownership programs under Part 91 Subpart K may maintain aircraft under a CAMP as provided in 14 CFR 91.1411. Owners and operators of large airplanes, turbojet multiengine airplanes, turbopropeller-powered multiengine airplanes, and turbine-powered rotorcraft under Part 91 select an inspection program under section 91.409(f). The 91.409(f)(4) option, a custom program approved by the Administrator, can resemble a CAMP in scope, but it is a distinct approval pathway and not a CAMP.⁵

The Ten Program Elements

A CAMP must contain ten elements. The FAA evaluates all ten before granting approval, and while exact regulatory language varies slightly between Part 121, 135, and 91 Subpart K, the functional structure is the same.⁶

Maintenance instructions covering routine and non-routine work on airframes, engines, propellers, appliances, and emergency equipment.
An organizational chart showing responsibility from line mechanics through senior management.
A maintenance schedule setting intervals for inspections, overhauls, and component replacements.
Maintenance methods standardizing how each task is performed across locations and shifts.
A recordkeeping system documenting every action, inspection result, and component change.
A training program covering initial qualification and recurrent skills for maintenance personnel.
An administrative control system managing work assignments, scheduling, and day-to-day operations.
A Continuing Analysis and Surveillance System, known as CASS.
A maintenance program effectiveness assessment reviewing whether the program is meeting its safety objectives.
A contract maintenance oversight program for any work outsourced to third parties.

The elements interlock. A deficiency found by the surveillance system triggers corrective action, which feeds back into updated instructions and training. The FAA looks for that closed-loop logic during review, and operators who treat the ten as separate paperwork items tend to stall during certification.

CASS: The Ongoing Requirement

CASS is the element that most often trips operators up because the work continues long after initial approval. The FAA defines it as a continuous, safety-based, closed-loop cycle of surveillance, investigation, data collection, analysis, corrective action, monitoring, and feedback.⁷

The operator has to collect two kinds of information. Performance verification comes from audits of work in progress, individual maintenance transactions, and broader systems. Effectiveness verification comes from operational data: maintenance-related delays, component failure rates, discrepancy rates after heavy maintenance visits, and trend analysis.

When a problem surfaces, the operator conducts a root cause analysis rather than patching the symptom. The department responsible for the deficiency develops the corrective action plan so the people closest to the work own the fix. That plan must name who is responsible, set a completion date, specify the data that will confirm success, and account for possible unintended consequences. Immediate safety issues require immediate action; less severe findings may have 30 to 60 days for implementation. Follow-up audits verify the fix worked, and a finding can only be closed once effectiveness is confirmed. If the fix fails, the cycle restarts.⁸

Management Personnel Requirements

The FAA will not approve a CAMP without qualified people running the maintenance organization. Under 14 CFR 119.65, a Part 121 certificate holder must have qualified individuals serving full-time in at least five positions: Director of Safety, Director of Operations, Chief Pilot for each aircraft category, Director of Maintenance, and Chief Inspector. Those titles must appear in the operations specifications, and personnel changes must be reported to the responsible Flight Standards office within 10 days.⁹

The Director of Maintenance qualifications are especially detailed. The person must hold a mechanic certificate with airframe and powerplant ratings, at least one year of experience in a position responsible for returning aircraft to service, at least one year of supervisory experience maintaining the same category and class the operator flies, and three years of relevant maintenance experience within the past six years. Those three years must include work on large aircraft with ten or more passenger seats or at a certificated airframe repair station rated for the same category and class.¹⁰

The FAA may approve a different management structure if the operator can show it will maintain the highest degree of safety with the alternative, based on the kind of operation, number and type of aircraft, and area of operations.⁹

Manual and Operations Specifications

Every operator needs a maintenance manual that shows, in writing, how the organization satisfies the ten elements. The regulations specify what the manual must contain: the method for performing routine and non-routine maintenance, a designation of required inspection items, procedures for reinspection of work performed after previous inspection findings, standards for acceptance or rejection, and instructions preventing the same person from both performing a required inspection item and inspecting it.¹¹

The manual must include the organizational chart, a list of any outside entities performing maintenance or inspections, and procedures ensuring that no inspector’s decision on a required inspection can be overridden except by supervisory personnel within the inspection unit or a person with overall administrative responsibility for both inspection and maintenance. Work interruption procedures are required so that maintenance stopped mid-task gets properly completed before the aircraft returns to service.¹¹

The Operations Specifications are the document that records the FAA’s authorization for the operator’s specific program scope. Every field has to reflect the operator’s actual aircraft tail numbers, engine types, and organizational roles. Templates and guidance sit in the FAA’s Flight Standards Information Management System.¹²

How the FAA Approves the Program

Approval runs through a five-phase certification process laid out in FAA Order 8900.1. The pre-application phase begins when the operator submits a formal application letter with a pre-application checklist, which prompts the FAA to assign a Certification Project Team.¹³

Phase 2, Formal Application. The FAA reviews the complete application package, holds a formal application meeting, and verifies that gate requirements are met before proceeding.
Phase 3, Design Assessment. Inspectors evaluate whether the operator’s systems are designed to comply with regulations and safety standards. The FAA considers this the most critical phase because it tests whether policies and procedures actually manage risk.
Phase 4, Performance Assessment. The operator demonstrates the systems work in practice through demonstration events, aircraft conformity evaluations, tabletop exercises, and proving tests.
Phase 5, Administrative Functions. Once the operator has corrected significant unsatisfactory items and proven full capability, the FAA issues the air carrier certificate and signs the approved operations specifications.

The principal inspector or another aviation safety inspector with signature authority signs the OpSpecs. That signature is the moment the drafted procedures become a legally binding framework, and the operator receives a copy as formal confirmation the program is authorized.¹⁴

Reliability Programs Are Optional

A reliability program is a tool, not a requirement. Operators running a CAMP may elect to use statistical reliability methods to set their own maintenance schedule intervals instead of submitting fixed time limitations for individual FAA acceptance.¹⁵

The option is open to Part 121 carriers, Part 135 operators subject to CAMP requirements, and Part 91 Subpart K operators maintaining aircraft under a CAMP. There is no minimum fleet size. An operator that chooses this path must obtain FAA acceptance of the reliability standards and receive OpSpecs or Management Specifications authorizing its use. Intervals can then move with actual performance data, extending when trends support it and shortening when failure rates climb.¹⁵

Penalties for Non-Compliance

Enforcement runs from administrative remedies through certificate revocation. The FAA adjusts civil penalty maximums for inflation. Under the adjustment effective December 30, 2024, a violation by a person other than an individual or small business concern carries a maximum civil penalty of $75,000 per violation. Individuals and small business concerns face a maximum of $1,875 per violation. Knowing presentation of a nonconforming aircraft for an initial airworthiness certificate can reach $1,212,278.¹⁶

Beyond fines, the FAA can suspend or revoke a certificate. A fixed-duration suspension is a disciplinary measure. An indefinite suspension keeps the operator from exercising any certificate privileges until it demonstrates it meets required standards again. Revocation means the FAA has determined the operator is no longer qualified to hold the certificate at all. Most enforcement cases begin with an opportunity for informal procedures, such as a conference with an FAA attorney, and many settle without full litigation. Operators with a pattern of CAMP deficiencies get far less favorable treatment than those with an isolated lapse.¹⁷
