AI Makes Things Up. That's Why Engineers Sign.
Engineers are right to worry that AI hallucinates. The answer isn't to keep it out of continuing airworthiness. It's to bring it in under engineering control, the way aviation adopted autopilot and fly-by-wire.
Accountable Managers, CAMO engineers, airworthiness engineers · 2026-10-09Why an Aircraft's Compliance History Follows Its Airframe — Not Its Tail Number
A registration mark is an event; the airframe is the identity. Why AD applicability and compliance history belong to the type certificate and MSN — and what changed in the free Aviagent AD lookup.
CAMO, lessors, airworthiness engineers · 2026-08-20Which Airworthiness Directives Apply to Your Aircraft — and How Applicability Is Really Decided
How airworthiness-directive applicability is actually decided — by type certificate, MSN, mod state and engine variant — and why an alert isn't an answer.
CAMO / operators · 2026-07-11What Is a Transition CAMO — and the AD-Status Review That Makes Handovers Clean
A transition CAMO takes over continuing-airworthiness management for a fleet. Here's the AD-status review that makes the handover clean — and the risk it removes.
Transition CAMO · 2026-07-11Superseded and Recurring ADs: Keeping a Fleet Current
How AD supersedure and revisions work, why a superseded AD still matters, and how recurring ADs keep coming due — so your fleet's AD list stays current and correct.
CAMO (practical) · 2026-07-11EASA vs FAA Airworthiness Directives: Comply-Once, Cross-References, and What Actually Applies
How EASA and FAA airworthiness directives relate — MCAI, comply-once, cross-references — and how to avoid double-counting or missing a cross-jurisdiction AD.
CAMO (mixed EASA/FAA fleets) · 2026-07-11Back-to-Birth Records: How Far Back Airworthiness Evidence Must Go
What 'back-to-birth' means for airworthiness records, which parts need full traceability (LLPs), and how gaps hurt value at transfer — plus how to keep the chain intact.
Records / documentation teams · 2026-07-11Building an Audit-Ready AD Evidence Chain for Your Next Authority Audit
What auditors expect from your AD compliance evidence — timestamped, traceable, per-decision — and how to build an evidence chain from AD to sign-off you can defend.
CAMO managers / Accountable Managers · 2026-07-11AD Deadlines Explained: Flight Hours, Cycles, and Calendar Limits
How airworthiness-directive deadlines work — one-time vs recurring, flight-hours vs cycles vs calendar — and how to compute the next due point per aircraft without surprises.
CAMO (practical) · 2026-07-11AD Compliance at Aircraft Redelivery: The Lessor's Checklist
A practical AD-compliance checklist for aircraft redelivery and lease return — applicable ADs per tail, evidence, open items, and a clean airworthiness position at transfer.
