Aerospat and Westlands used the same construction number sequence. The Westland aircraft numbers being prefixed WA/.
HA-LFM is 1301 so should be Aerospat built. The Yugoslav aircraft had a separate sequence of their own.
What is interesting is if the 341H have actually been converted to 341G standard how was it done.
I wonder if this all happened before Hungary joined EASA (assuming they are in EASA!!!).
Could be these aircraft have grandfather rights. What is for certain is they are not listed on the engineers EASA 66 type rating list. However the helicopter section of that list is probably only about 90% accurate and is still being ammended.
The Brasov built Alouette 3's and Puma's are also not listed.
