Just goes to show how bad things have got. If they think they struggled with a 4th Generation airframe like the Embraer how are the engineers going to deal with these old clunkers. Not to mention the well documented oil fumes problems. Engine TBOs around the 5500 hrs and 2300kg/hr as long as there is no icing. Hope they can find a few blacksmiths to deal with the known mainspar corrosion issues as well.
