– History of Updates
13.1 Engine Serial Number Decode
All engines are allocated
a master serial number at manufacture that is referred to as the “A number”:
2200 engines = 22A-XXXX, 3300 engines = 33A-
XXXX, where “XXXX” is a sequential number.
Certified engines are then allocated an additional sequential number that is referred to as
the “B
number”, “C number” (or in older engines the “J number”): 2200 engines = 22B-XXX, 3300 engines =
33L-
XXX, where “XXX” is a sequential number.
All engine records require reference to the “A number”.
The master list of A numbers and the cross-reference to B (C or J) numbers is kept in the Jabiru
Engines department, and all enquiries should be directed there: [email protected]
