the AW139 is a fine aircraft, with awesome power, impressive speed, and whilst the payload may be slightly limited on longer sectors, the MAUW is expected to increase soon.
there has been some issues on introduction such as cracks in exhausts and some minor airframe cracks now repaired. parts availabilty has been an issue but now improving.
the passengers all like it and compared with the same stage that the S76 was introduced things are better I am told (being too young to remember myself)
impress to inflate : what is wrong with the CHC spec? they have everything you would expect for an offshore a/c
I have heard so many negative things from people do dont fly them but everyone I know who does thinks they are the business !
