What you get
ATA-chapter guides
Fault-isolation guides organised by ATA chapter: the symptom as the crew or maintenance sees it, then the probable causes.
Ranked probable causes
Each cause carries a likelihood, the checks that confirm it, and the corrective action — worked top-down.
Case log
Open a case from any guide, record the aircraft, tail, notes, and outcome, and mark it resolved when you close it out.
PDF export
Export a worked case — the guide it referenced and your findings — as a PDF for the record or for follow-up.
