Please could you provide the year of manufacture for Rotax 912 4380792 ( Certified Engine ) & also any detail of history of ownership of this engine.

I know this engine is in a 2012 uk registered microlight & was fitted as NEW but I suspect it was previously used in a 1995/1996 built aircraft.

Any details you have on this engine would be useful as if it is a 1995/96 ENGINE it is now time expired, but if it is a 2012 ENGINE it is still in currency.

MTIA,
Peter

There's no configuration info in the database for engines of that vintage, and it is not showing as registered (no history).

Engine Serial Number: 4380792
Engine Type: ROTAX 912 A

HI, I have several Rotax 503's, 377's and 618 that i would like to know the manufacturer date for. If it is possible could I get the years made for the following serial numbers?
618 = 4177725
503 = 3975034
503 = 4937458
503 = m5432355
377 = 3443750
377 = 3476289

4177725 was produced 21-Jul-1993
Engine Serial Number: 4177725
Engine Type: ROTAX 618 UL
Model Number: 306180010

5432355 was produced 21-Mar-2001
Engine Serial Number: 5432355
Engine Type: ROTAX 503 UL FAN
Model Number: 305030010

As for the others, they all predate the electronic database system.

3975034 : "Your Engine is not listed in the system"
3443750 : "Your Engine is not listed in the system"
3476289 : "Your Engine is not listed in the system"
4937458 : "Your Engine is not listed in the system"

We were able to examine the North American distributor's paper archives, and none of those engines are listed there either. Possibly they originated with a European distributor. It's also possible that some of them could actually be snowmobile engines. But based on the paper records, the numbers indicate they are likely from the following date ranges:

377 = 3443750 : Mid-80s, probably 1985
377 = 3476289 : Mid-80s, probably 1985
503 = 3975034 : Late 1990-early 1991
503 = 4937458 : 1999 (spring)
