No, I could be wrong but I doubt that airworthiness will be the main factor if any at all in this latest development. From the off the legality of the sortie and the pilot to fly it have been questioned and I suspect that it is this what might be behind it.
It might have been a better outcome if the sortie had commenced as originally planned in the morning when the pilot would likely have fared much better given that I think he was essentially qualified as a day flyer only and with no apparent instrument rating. Breaches of other rules and regulations might well come to light but I suspect that the licensing and suitability of the pilot to fly the sortie will feature uppermost at the end of the day. I don't envy whoever engaged him for the job.
