Thank you for your response. Back in the late 1990s Turbomeca were very keen to come up with a "package" that would enable the MoD to buy and install Makila into the Puma but the the airframe desk at the time would not support an uprated engine installation without the corresponding transmission and gearbox upgrading. I find it a pleasant surprise that they are now happy to go down this route. There has always been a certain amount of disagreement between the engine manufacturer and the airframe manufacturer regarding the engine to airframe integration hence the problems that occured when the last flector pack mods were introduced. It is great news to hear that this has all been resolved and both manufacturers and the Puma IPT are supporting an upgrade that does not involve any requirement to upgrade the transmission. I am sure the Helicopter Engine IPT will fully support such a proposal as the operating costs of the Makila are far more economical than that of the Turmo IIIC4 and I am sure that Turbomeca would only be too pleased to come up with a total support package. Mind you I am sure there are still restrictions and a certain amount of confusion regarding what the limits are when about operating at the higher MAUW ( the figure of 1% of the life comes to mind), I hope that the introduction of the HC Mk2 will overcome this problem also.
