The Type Certification process
Phase 2 - Familiarisation & TC Basis preparation
Type Certification Basis
Set of applicable requirements under which the aircraft is certified:
• Date of application freezes the JAR 25 / FAR 25 amendment for which the aircraft
needs to be compliant
“Reference Date”; EASA & FAA may have different reference dates
• Type Certification must be achieved within 5 years of the reference date, unless
specifically determined by the authorities (IR21.17)
If this is not achieved, EASA or FAA may require compliance
with further rule amendments.
