Occurrence Reporting

Operator will advise Rolls-Royce AST within 24 hours in case of engine related events such as:

Air turn back
In-flight shut down
Diversion
Aborted take off
Rundown
Flame out

Information regarding engine details, location, description of event and subsequent actions should be provided to Rolls-Royce AST in electronic format.

Safety Reporting Requirements

Immediate Reporting

Conditions that have resulted or may result in an unsafe condition that seriously hazards flight safety shall be reported immediately to the local airworthiness authority for the reporting Part-145 organisation and as applicable the Design organisation.

EASA Occurrence Reporting (AMC 20-8)

When deviations or technical anomalies are discovered (e.g., use of incorrect methods, deviations from approved procedures/data, technical defects affecting airworthiness), Rolls-Royce must immediately report per EASA requirements (AMC 20-8) and IOSA requirements to the operator Power Plant Team for the operator to inform its Authority within 72 hours.

Unsafe Condition Reporting

After identifying an unsafe condition (including uncontained failure of engine critical components, fuel leakage hazards, fuel system malfunctions, or toxic fumes in cabin air supply), the Product Chief Engineer will issue a safety report within 72 hours. A Follow-Up report shall be issued within 30 days of the initial report for EASA certified products.

Maintenance Data Requirements

At maintenance sites, Rolls-Royce and its Maintenance Providers shall be in possession of and use all Maintenance Data necessary for maintenance of the Engines in accordance with OEM recommendations and applicable CAA requirements.

  • Customer is responsible for making all customer-specific Maintenance Data and revisions available to Rolls-Royce
  • Rolls-Royce will make data available to its subcontractors when applicable
  • Customer shall ensure availability of customised maintenance data with correct revision status for aircraft covered under the agreement
  • All maintenance data and other applicable manuals will be available online as informed to the maintenance provider

Investigation Data (QAR)

In the event of an aircraft or engine investigation, Rolls-Royce may need to request additional data such as QAR (Quick Access Recorder). This data must be provided to Rolls-Royce in a decoded, agreed format.

Providing access to QAR data in a timely manner will significantly reduce response time to issues and investigations, and minimise operational disruption.

Engine Removal Report

The EHM Service Provider produces an engine removal report which can be viewed by Rolls-Royce and Customer, and used by Overhaul Base for workscoping (e.g., checking vibration levels to avoid pass-off rejections).

Pro Tip

Ensure data transmission is set up in accordance with the requirements in the relevant ORR document to enable proper EHM service delivery.
