Intelligent Automation Corp. has won U.S. Army approval for two additional airworthiness releases for U.S. Army CH-47 Chinook helicopters equipped with its Condition-Based Maintenance (CBM) health and usage monitoring system (HUMS).
The airworthiness releases were awarded as a result of the demonstrated performance of IAC’s 1209 HUMS. Two other airworthiness releases are under U.S. Army consideration.
The U.S. Army’s approval process involves a two-phase approach to determine whether certain maintenance procedures may be safely eliminated. Diagnostics must be validated through multiple instances of fault indications that are supported by extensive off-aircraft (seeded fault) testing to establish failure progression rates that are required for prognostics.
Diagnostic threshold levels are then refined allowing further prosecution of fleet anomalies. The Army also performs careful teardown analysis.
