Kind of like the DC-9-10 series, eh? What, 5% of the DC-9-10 fleet crashed
on take off because of wing contamination?
Even more similar to the Fokker F-28 series, a similar size & weight
aircraft (well, compared to a DC-9, anyway). Crashes at Dryden and La Guardia
because of wing contamination. The Fokker report says that one 1mm ice
particle per square centimeter of wing reduces lift coeficient by at least
22%.
