Diagnosis
Eastern Air Command's dip is concentrated in May 2026, driven by 11 AOG aircraft with open unscheduled snags. Each traces to a failing high-criticality component whose required spare is below reorder with a long lead time — so the aircraft cannot be restored until stock is positioned.
Prescription: expedite the high-AOG-risk spares below, pre-position at the affected bases, and prioritise the open snags by criticality.
