Continuing Airworthiness

The CONTINUING AIRWORTHINESS MODULE provides the necessary tools to efficiently manage continuing airworthiness processes, giving you confidence that your organisation is complying with regulatory obligations.

OASES maintains and reports reliability statistics at a fleet level and automatically generates graphical reports for utilisation, in-service and maintenance defects, dispatch reliability, component removals and open defects. The OASES user may easily define additional defect classifications e.g. ‘cabin defects’ and the system then automatically collects and reports statistics for these. The report function also offers full ATA and component removal analysis enabling detailed interrogation of the high-level data.

OASES maintains a model of each aircraft that defines all significant component locations. Each component location comprises an 8-character ATA identifier and description which together with position and zone indicators give unique identification and control of all monitored components and systems.

The system maintains elapsed life data for all components including time since new, since fit, since overhaul and since repair. This data is easily accessible and can also be displayed for any given historical date. All maintenance and modification tasks are linked directly to the airframe, location or component as appropriate.

Component assemblies may be defined to any required depth and OASES understands that removal of any master/sub component requires all sub-assemblies are also removed.

OASES maintains all tasks within the approved maintenance programme (AMP) and ensures only those of the current revision are issued to a works order. Changes to the AMP may be developed online within the system and, once approved, may be updated instantly to the new revision.

The module also controls all AD, SB, SIL, AOT etc. Each entity may be defined by the user and complex relationships can be modelled and are automatically set for the reverse relationship. A work flow sequence may be defined against each category and the system can intelligently route each stage depending on fleet type. OASES can be configured for automatic download of AD source documentation (EASA) and provides an easily auditable record of all transmittals generated in this way. Each record is held centrally and may be effective across multiple fleets, aircraft and components.
