Terms & Conditions

Last Updated: March 2026

1. Acceptance of Terms

By accessing and using Online Aviation Library (onlineaviationlibrary.com), you accept and agree to be bound by the terms and conditions of this agreement. If you do not agree to these terms, please do not use our website or purchase our products.

2. Our Mission & Purpose

Online Aviation Library, operated by Sicuro Publishing, is a legacy preservation project founded by aerospace engineers committed to preserving aviation technical documentation for the global community. We are not a commercial vendor—we are archival partners dedicated to ensuring aviation knowledge is preserved, organized, and accessible to restorers, researchers, historians, museums, and enthusiasts worldwide.

Our Role: We acquire documentation from the aviation community (collectors, estates, archives, professionals), reassemble scattered materials into coherent collections, elevate the documentation with engineering context and professional organization, and share it with everyone who needs it.

Community Service Commitment: We work alongside type clubs, owner associations, museums, and Type Certificate holders as inclusive partners—not competitors. Our goal is official recognition as a trusted community service organization preserving aviation heritage.

3. Product Description & Use

What We Provide: Structured digital aviation documentation collections including historical aircraft technical manuals, blueprints, engineering drawings, maintenance procedures, and parts catalogs. Each collection is professionally organized with engineering rigor, historical context, variant mapping, and curated indexing.

Scope and Purpose: These materials are provided for historical reference, research, restoration guidance, and archival purposes. Content consists of original or reproduced documentation from aircraft operational periods, now preserved in electronic format and organized for modern access.

Living Collections with Free Lifetime Updates: Our collections are never "finished." As we acquire additional documentation, technical bulletins, or variant-specific materials, we update collections and provide free lifetime updates to all purchasers. Your one-time purchase guarantees access to all future additions and improvements.

Not for Active Airworthiness Compliance: These historical materials are NOT intended for current certification, repair, or airworthiness compliance on aircraft still in service. For active aircraft, consult current Type Certificate holders, regulatory authorities (FAA, EASA, Transport Canada, etc.), and approved maintenance organizations for up-to-date airworthiness data, Service Bulletins, and Airworthiness Directives.

Content Accuracy: Information is provided for reference only. We do not guarantee completeness, accuracy, or currency of historical materials. Users must independently verify all technical data before application. Historical documentation reflects
