FAA Compliance
Logbook by Project 1903 is designed to meet FAA standards for electronic signatures, electronic recordkeeping, and electronic manuals as outlined in AC 120-78B.
No FAA Approval Required for Part 61, 63, 65, 91, 129, or 137 Operations
According to FAA AC 120-78B Section 1.9.5: "There is No Requirement for Formal Approval, Acceptance, or Authorization for 14 CFR Part 61, 63, 65, 91 (excluding 91K), 129, or 137."
This means most general aviation pilots, aircraft owners, and maintenance personnel can use Logbook immediately without FAA approval. However, we recommend following the guidelines set forth in AC 120-78B to ensure your electronic logbook meets all regulatory requirements.
Working with the FAA for Part 121, 125, 135, and Other Operators
For operators under 14 CFR Parts 121, 125, 135, 91K, and other commercial operations, we are actively working with the FAA to obtain formal approval through OpSpec A025. Our system is designed from the ground up to meet all requirements for electronic signatures, electronic recordkeeping systems, and electronic manual systems.

How Logbook Complies with AC 120-78B
Electronic Signatures (Chapter 2)
Our digital signature system meets all key elements required by AC 120-78B for valid electronic signatures:
Signature Uniqueness
Each signature is cryptographically unique to the signer using secure authentication methods.
Identity Authentication
We verify and authenticate each signer's identity through secure login.
Sole Control
Signatures are under the sole control of the signer through password-protected accounts and secure sessions.
Intent to Sign
Users are prompted before signing and must take deliberate action to affix their signature.
Nonrepudiation
Signatures include timestamp and certificate information to prevent denial of signing.
Permanent & Unalterable
Once signed, documents cannot be edited without invalidating the signature and requiring a new one.
Digital signature interface
Electronic Recordkeeping (Chapter 3)
Our electronic recordkeeping system provides equivalent or better data integrity, accuracy, and accessibility than paper records:
Controlled Access
Role-based access control ensures only authorized users can view or modify records.
Record Preservation
Records are preserved and unalterable without proper authentication. Audit trails track all changes.
Data Protection
End-to-end encryption protects confidential information and prevents unauthorized access.
Backup Measures
Automatic daily backups to multiple secure servers ensure records are never lost, with disaster recovery procedures in place.
IT System Support
24/7 monitoring and support with provisions for system outages and data protection.
Complete Record Data
All required elements are captured: event type, date/time, personnel, aircraft info, and signatures.
Signed and locked maintenance entry with complete audit trail
