Airline-Specific Risks & Pain Points

AMOS warranty flag relies on manual technician input; missed flags cause unrecoverable cost leakage when discovery exceeds OEM claim window (typically 90 days)
OEM warranty terms scattered across multiple Ariba contract line items; exclusions for airline-induced damage (e.g. FOD, corrosion) frequently disputed without clear documented threshold
CAMP component records can have gaps when aircraft are acquired from lessors or third-party MROs; incomplete records lead to OEM claim rejection citing unverifiable maintenance history
Borescope images stored outside AMOS in file shares; retrieval is manual and inconsistent — OEMs (CFM, Pratt & Whitney) require image sets in specific DPI/format standards or reject claims on technical grounds
Each OEM (Airbus, CFM, Honeywell, Collins Aerospace) has different checklist formats and portal requirements; maintaining current versions of each OEM's checklist is a manual process with no automated update feed
Labour rate and material cost calculations reference SAP actuals — discrepancies between AMOS work order cost codes and SAP cost centres cause reconciliation errors that delay settlement
