Dry Lease and Sham Lease Issues in Aviation Litigation

Leasing structures in aviation—particularly dry leases and so-called sham leases—create recurring doctrinal disputes over operational control, regulatory compliance, and liability allocation. These arrangements matter because they can obscure which entity exercised operational authority over maintenance, crew, and flight operations at the time of an accident. The issue frequently intersects with federal regulatory frameworks, FAA certification and leasing rules, and evidentiary determinations regarding control and responsibility.

Conceptual Overview

Aviation leasing is not merely a financial mechanism; it is also a regulatory classification that can influence which party bears operational authority and may affect how legal responsibility is analyzed. A true dry lease transfers possession of the aircraft without crew and is intended to place operational control with the lessee, subject to the actual conduct of the parties. By contrast, a sham lease is generally understood as a nominal arrangement that purports to shift responsibility while factual control remains with the lessor or another entity.

The distinction is doctrinally significant because operational control is frequently a significant factor in aviation accident liability analysis, though courts may also consider ownership, agency relationships, contractual undertakings, and jurisdiction-specific doctrines. Courts and regulators therefore examine the substance of the relationship rather than the contractual label. Where a lease structure is inconsistent with actual operational conduct, it may be disregarded for regulatory purposes and may be treated differently in civil litigation depending on the claims asserted and the governing law.

Operational or Legal Context

Dry leasing is commonly used in general aviation, charter-adjacent structures, and certain corporate fleet arrangements. Under a legitimate dry lease, the lessee is generally expected to assume responsibility for:

• Providing crew
• Maintaining the aircraft in compliance with applicable FAA requirements
• Exercising operational decision-making authority

In contrast, sham lease characterizations often arise in enforcement or litigation contexts where an arrangement appears structured in a way that may avoid regulatory obligations—such as those imposed under Part 135—by characterizing a flight as private or shifting nominal control to a customer or affiliated entity. The FAA has long scrutinized such arrangements, particularly where the lessor continues to supply crew, dictate flight operations, or manage scheduling.

These issues frequently emerge in multi-entity structures involving aircraft management companies, charter operators, and special-purpose ownership entities. The formal lease agreement may not reflect the practical reality of how the aircraft is operated on a day-to-day basis, and that divergence often becomes central to both regulatory analysis and civil discovery.

Regulatory or Doctrinal Framework

The Federal Aviation Regulations define “operational control” as the exercise of authority over initiating, conducting, or terminating a flight. This concept is central to evaluating lease validity, but it is ultimately a factual determination based on how the parties actually operate. FAA guidance and enforcement practice emphasize that operational control cannot be reassigned through contract if the factual circumstances indicate otherwise.

Key considerations in this analysis may include:

• Whether the lessee actually selects and controls the crew
• Who bears responsibility for maintenance and airworthiness compliance
• How flights are scheduled and authorized
• Whether compensation is being received in a manner implicating commercial operation rules

Where a lease arrangement is inconsistent with these factors, the FAA may treat the operation as noncompliant with applicable commercial-operation requirements. That can lead to enforcement consequences, including certificate-related action in appropriate circumstances. In subsequent litigation, those regulatory issues may also become relevant as part of the factual record, although regulatory noncompliance does not automatically establish civil liability, and regulatory compliance does not automatically defeat it.

The analysis may also intersect with federal preemption principles, but any such effect is claim-specific and jurisdiction-specific. The allocation of responsibility under FAA regulations may inform how courts analyze certain state-law theories, yet it does not create a uniform rule displacing all parallel tort claims. That broader issue is discussed in federal preemption in aviation product liability.

Litigation or Evidentiary Significance

In accident litigation, leasing disputes often become threshold issues that shape party alignment and liability exposure. Courts do not rely solely on the lease document; instead, they may examine operational evidence such as:

• Crew employment and training records
• Maintenance logs and oversight structures
• Dispatch communications and scheduling authority
• Insurance policies and named insured designations

Discovery frequently reveals discrepancies between contractual language and operational practice. Where such discrepancies exist, plaintiffs may argue that the lease is a façade designed to obscure actual control or avoid regulatory obligations. Defendants, in turn, may rely on documented allocation of responsibilities, operational procedures, and evidence of FAA-aligned practices to support the legitimacy of the arrangement.

Expert testimony is frequently used to interpret FAA regulations and industry practices, particularly on questions of operational control, crew authority, and management-company functions. In some cases, these issues may substantially affect summary-judgment analysis or trial allocation of fault. Even so, agency findings and investigative material are not necessarily dispositive, and their use may remain subject to applicable evidentiary limitations.

Relevance to Aviation Accident Litigation

Leasing structure disputes are especially consequential in complex, multi-party aviation cases. Determining who exercised operational control can affect not only liability analysis, but also indemnity positions, insurance coverage disputes, and procedural posture. These issues frequently arise in cases involving charter operations, aircraft management companies, and corporate flight departments.

In the context of aviation accident cases involving charter or managed-aircraft structures, sham lease allegations can reshape the case by expanding the pool of potentially responsible parties and reframing how operational conduct is understood. A detailed discussion of how these operational-control questions are analyzed is addressed in the firm’s article on operational control in private, charter, and managed aircraft. They may also affect how investigative findings—such as those developed through the NTSB investigation process—are evaluated alongside the broader evidentiary record.
