An AI inspector aircraft technicians call on FaceTime.

A technician FaceTimes LineCheck with their hands still on the aircraft. It takes the tail number by voice, inspects a photo of the part, cites the exact section of the FAA repair manual, checks service difficulty history and airworthiness directives, and drafts the work order. A certificated mechanic reviews and signs.

Two-minute recording of a real FaceTime call with LineCheck, filmed live. A three-minute version shows the full call. Or replay the call on the work-order board, step by step.

The LineCheck work-order board after a real call

The work-order board after a real call: the pipeline across the top, the inspected photo and findings on the left, the draft record, manual citations, directives and service history on the right.

The first design decision

LineCheck assists and documents; it never says a part or an aircraft is airworthy, serviceable or safe to fly. Every record stays a draft until a certificated mechanic signs it.
