About Us
Preserving Aviation Heritage for the Global Community
Online Aviation Library, operated by Sicuro Publishing, exists to preserve aviation technical documentation and make it accessible to the worldwide community of restorers, researchers, historians, museums, educators, and enthusiasts. We are not vendors—we are archival partners committed to ensuring that aviation knowledge is preserved, organized, and shared with all who seek to understand and maintain these magnificent machines.
Our Mission
Founded by aerospace engineers who lived the industry's triumphs and challenges, Sicuro Publishing represents a legacy commitment to the aviation sector. We understand what these documents mean because we've worked in the field—designing, building, and preserving aircraft knowledge throughout our careers. This is our way of giving back to the community that shaped us.
Our mission is simple: preserve aviation heritage and democratize access to technical documentation. We believe aviation knowledge should be organized, structured, and accessible to the community. Every manual we preserve, every blueprint we organize, every collection we curate serves the greater goal of keeping aviation history alive and accessible.
Our Vision and System
We recognize that many individuals and companies make a living providing aviation information—and we respect that ecosystem. We do more because we have a vision: to preserve aviation documentation that risks being lost as the community moves forward.
The aviation community is always looking ahead—new technologies, modern aircraft, current certifications. But in that forward momentum, critical historical documentation gets overlooked, forgotten, or lost. Estate sales scatter collections. Archives close. Knowledge holders pass away. Documents deteriorate in basements and hangars.
We look back to preserve what others overlook.
We are not a museum. We are an active documentation preservation service that:
- Buys from the community - We acquire documentation from collectors, estates, archives, and aviation professionals before it's lost
- Rescues overlooked materials - We preserve documents the community has moved past but future restorers will desperately need
- Reassembles scattered information - We reconnect documents separated by decades and geography into coherent collections
- Elevates the documentation - We add engineering context, historical background, variant mapping, and professional indexing
- Preserves for the future - We ensure today's "old paperwork" becomes tomorrow's essential restoration reference
- Shares with the community - We make organized collections accessible to everyone who needs them
Our system brings engineering discipline to preservation:
- Structured collections organized by variant, production period, and system coverage
- Engineering norms and standards from the original production era
- Clear scope definition—you know exactly what's included
- Professional indexing and folder hierarchies
- Curated selection based on technical relevance
- Continuous acquisition - We never stop looking for overlooked documentation to preserve
Why Preservation Matters
The aviation community moves forward—and that's good. But someone must look back and preserve what's being left behind.
What happens without preservation:
- Estate sales scatter lifetime collections across dozens of buyers
- Archives close and documents disappear into storage or disposal
- Knowledge holders retire or pass away, taking institutional memory with them
- Original manufacturers' archives are lost in corporate mergers and bankruptcies
- Documents deteriorate in hangars, basements, and forgotten filing cabinets
What we preserve:
- Factory documentation from manufacturers no longer in business
- Military technical orders from obsolete aircraft programs
- Engineering drawings before they're lost to time
- Maintenance procedures before the last mechanic who knew them retires
- Variant-specific documentation the community has moved past
- The links between scattered pieces of information that make collections truly useful
We are the bridge between yesterday's documentation and tomorrow's restoration needs. The 1940s manual gathering dust today becomes the critical reference for a 2030s restoration project. We preserve it, organize it, and keep it accessible.
Inclusive, Not Exclusive
We are committed to being inclusive partners within the aviation preservation ecosystem:
- We work with type clubs, owner associations, and museums—not against them
- We complement official Type Certificate holders and OEM support networks
- We collaborate with restoration communities, sharing knowledge freely
- We support academic research, historical preservation, and educational initiatives
- We provide lifetime updates to all purchasers—ensuring knowledge remains accessible
Our goal is official recognition as a community service organization preserving aviation heritage through professional organization and structured access.
What Makes Our Collections Different
As aerospace engineers, we bring professional discipline to documentation organization:
Structured Collections with Engineering Rigor:
We don't just scan and sell PDFs. We acquire documentation from multiple sources, organize it by engineering logic, add historical context, map variants, and create professional folder structures that make sense to engineers, mechanics, and restorers.
Living Archives with Free Lifetime Updates:
Our collections are never "finished." As we acquire additional documentation, technical bulletins, variant-specific materials, or supplementary references, we update collections and provide free lifetime updates to all purchasers. Your one-time purchase guarantees access to all future additions and improvements. This is our commitment to the community.
Historical Context and Technical Depth:
Every collection includes comprehensive historical background, operational significance, engineering innovations, and the stories of the people who designed, built, and flew these aircraft. We preserve not just the manuals—we preserve the knowledge and heritage.
Engineering Standards and Norms:
We document the engineering practices, certification standards, and manufacturing norms from each aircraft's production era. This context is essential for understanding how these aircraft were designed, built, and maintained.
Our Legal Framework
Copyright Ownership:
Our copyrights, registered in Canada under Sicuro Publishing in the Canadian Copyright Database, cover the compilation, structure, indexing, and presentation of our collections. We do not claim ownership of underlying historical factory materials, which remain the property of their original creators or current rights holders.
Licensing Framework:
- For manufacturers no longer in business: We hold collective copyright agreements for their documentation archives
- For manufacturers still in operation: Bilateral agreements permit structured distribution of common information for obsolete aircraft models no longer in active production
- All content is provided under clear licensing terms with defined scope and usage rights
