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 specialist aviation documentation business built around a legacy preservation mission. Founded by aerospace engineers committed to preserving aviation technical documentation, Sicuro Publishing reflects more than 25 years of professional experience devoted to acquiring, preserving, organizing, and making historical aviation technical documentation 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 Commitment: We work alongside type clubs, owner associations, museums, and Type Certificate holders as inclusive specialist preservation partners — not competitors.
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Scope and Purpose: These materials are provided for historical reference, research, restoration-research guidance, and archival purposes.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. Historical documentation may have been revised, superseded, withdrawn, or replaced. Persons performing regulated aviation maintenance, repair, modification, or certification must independently obtain and use the current technical data required by the applicable authority, manufacturer, Type Certificate holder, or other authorized source. 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 standards, procedures, and specifications applicable at the time of original publication.
