Hello,

As soon as hearing the news, he wrote to me.

Can we say ''as soon as hearing the news, he wrote to me'' instead of ''as soon as he had heard the news, he wrote to me''?

Thanks.

No, we can't.

"As soon as he heard the news ..." or "On/Upon hearing the news ..." but not a combination of the two.
