FAA: Airworthiness directive ban necessary for old Cessna twins
The FAA says an airworthiness directive banning most early Cessna twins — except 337s — from flight into known icing is necessary because too many pilots were ignoring a mandatory service bulletin issued by the company in 1997 that says the same thing. Cessna sent out the bulletin after it became clear that even a little ice on almost 7,000 of the twins could seriously affect the slow-speed handling, resulting in a lot of hard landings.
