Can someone explain why they are only saying helicopters are affected?

YPJT,
Interesting web site to pull up that information from 1990/2000. However, the article is accurate.
My original comment about CASA involvement was based on CASA's reluctance to get involved, over a period of several years, in what, as I recall, turned out to be a quite long standing problem of EDA contamination.
It was left up to AOPA to recruit the late Prof. David Trimm, from UNSW, as an independent expert on the fuels. He very smartly got to the core of the problem.
As always, CASA is not renowned for "taking on" anybody who has the resources for a legal defense.
Tootle pip!!
