The biggest mistake with the Puma 1/2 conversion, IMHO, was the omission of the single wheel undercarriage. Having flown both the 330 and the 332, 3,000/9,500 hrs. I am a world authority on heavy landings. The 332 is rated to 5 m/s (950 fpm) and the maintenance manual isn't worried until it exceeds 7.5 m/s.
