Plan the completion and certification of a turboprop phase inspection

What is going on

Northern Aeromedical Services need their turboprop VH-NAM back on line by 19 September for patient transfers. The phase inspection under WO-26-1176 is stalled awaiting an elevator trim tab hinge, the propeller hub has been removed for an airworthiness directive inspection in the component workshop, and several airworthiness directive and service bulletin items remain in the work pack. A torque wrench needed for the propeller installation is due for calibration on 14 September, one engineer's authorisation on the type expires in October, and the aircraft requires an independent inspection on the trim system. Ruth Kaminski wants a completion plan, an allocation of authorised engineers and a certification package ready for release.

Your brief

Plan and sequence the remaining tasks of the phase inspection around parts, tooling and personnel constraints, verify the airworthiness directive and service bulletin status, allocate authorised engineers, prepare the certification and records package and brief the supervisors on the plan and its risks.

Work through it

You do not need to do it all. Doing a few of these will show you what the work is like. Your ticks and notes stay on this device.

• Read the Maintenance Certification and Release to Service Procedure and the Quality and Airworthiness Policy and list what must be complete before the certificate of release to service can be signed.
• Review WO-26-1176 in the Aircraft Work Orders system and the work pack, and list every outstanding task card, airworthiness directive item, service bulletin item and independent inspection.
• Check the Parts and Bonded Store Register for the trim tab hinge and any other parts required, and confirm the propeller hub inspection status with the component workshop.
• Check the Tool Control and Calibration Register for the tools required, including the torque wrench due for calibration, and arrange a calibrated replacement so the propeller installation is not delayed.
• Use the Personnel Authorisation and Training Register to allocate authorised engineers for each task, the independent inspection and the release, noting the authorisation expiring in October.
• Build a day by day sequence for the remaining work through to 19 September with hours, dependencies and a fallback if the hinge is late, including any afternoon shift required under the fatigue limits.
• Prepare the certification package checklist covering task card completion, parts traceability, airworthiness directive compliance entries, logbook and records updates and the release certificate.
• Update WO-26-1176 with the plan and brief Marcus Delaney and Fiona Lachlan in writing on the plan, the risks and the decisions needed from them.
