Definition of Hard Landing : Pilot’s point of view
Pilots judge subjectively paratively the landings as being:
Soft – Normal – Firm – Hard
Subjectively = modified or affected by personal views, experience, or paratively = In a relative manner; parison to something else
“Hard landing suspected”: when the pilot decide that a structural examination is necessary

Hard Landing information : Maintenance’s side
Maintenance uses objective data to classify the landings
Recorded vertical acceleration at aircraft CG
Recorded vertical speed using Radio Altimeter data
Limit values will depend of:
aircraft types and standards
Quality of recorded parameters

Classification of the landing by maintenance
After a suspected hard landing:
Classification of the landing using the Load Report
Normal landing = no actions required
Hard landing confirmed = perform inspection
Severe Hard Landing confirmed = AOG contact Airbus
Load Report not available = perform inspection

Hard Landing confirmed: Maintenance inspection
Inspection is divided in different phases
Phase 1: general inspection for primary damage and indication of remote damage (mainly external)
If damage = perform further inspection (phase 2) and required maintenance actions.
If no damage = end of inspection
No damage = Aircraft can temporarily return to service
Grace period (. 30 days or 100 - 200 cycles)
