Hidden Discrepancies: OCCM, LDND, and the Role of Audits in Aircraft Leasing & CAMO

In leasing and CAMO alike the real place an aircraft shines is the records – the gleaming exterior and pristine interior promise operational efficiency and passenger comfort; but beneath the surface, is the aircraft’s records.

Details such as the parts installed like OCCM which are on condition and condition monitored components. These are the components which remain in service based on their capability and serviceability as part of a system or standalone – they are not governed by a life span or a mandated overhaul based on time such as safe life items and hard time item.

The records should reflect the accurate listing of the parts, but the list is vast and so incomplete historical data can lead to costly surprises and operational disruptions down the line – when a component is replaced it might well be recorded and certified with the correct paperwork, but crucially if the component list does not reflect or capture the change, we can have discrepancies.

OCCM: The Present Picture

The OCCM list acts as a snapshot of the aircraft’s current configuration and is crucial for effective maintenance planning and ensuring compliance with airworthiness regulations.

LDND: The Complete Story

While the OCCM listing captures the present status, the LDND records tell the complete story as it tracks the components installed and the specific requirements verifying maintenance actions carried out and when they are next due ensuring the aircraft’s continued airworthiness as per the maintenance schedule.

The Import/Export and or Lease return audit: Unveiling the Truth

Importing or lease return of an aircraft presents a unique challenge. Incomplete or inaccurate OCCM status listings and LDND records from previous operators can create discrepancies – potentially masking hidden maintenance needs or not reflecting accurate status, but how much do we check – what do we check:

  • Physical Verification: Inspecting components to verify PNs and SNs against both the OCCM listings.
  • Document Review: The Maintenance records, logbooks, and historical data to verify part installation and or component change.

Do we review 100% of the records for an import, for a lease return, do we risk assess the prior CAMO and sample check; the benefits of diligence means uncovering hidden discrepancies and potential maintenance issues before they impact operations and compliance with lease return conditions.
