Re; Heron ‘ORG i have been told two different stories to explain the long-time on overhaul.
First was that DFS have been unable to process the engines as quickly as expected – but it wasn’t explained whether they have found problems or that their work load is high at the moment.
Secondly there has been corrosion found around the windows.

From previous chats with afew of the guys there I’d say the latter is most true. She was apparently in terrible shape in terms of corrosion, most of which by all accounts had been getting that way for a while….she cann’t have been very well looked after in the past given the few glimpses I have had inside her. To explain the long overhaul I believe her owner’s ran out of money as it was initially apparently only supposed to take afew months but rapidly overran when the corrosion problems arose.
