Salve ragazzi,
su airliners.net si parla di un atterraggio di emergenza per un MD-11Combi di Alitalia.
Apparentemente l'equipaggio aveva perso il controllo degli alettoni.....
Ecco il post

NTSB Identification: NYC03IA042
Scheduled 14 CFR Part 129: Foreign operation of Alitalia Linee Aeree Italiane SPA (D.B.A. Alitalia Airlines)
Incident occurred Tuesday, January 14, 2003 in Jamaica, NY
Aircraft: McDonnell Douglas MD-11-C, registration: I-DUPA
Injuries: 142 Uninjured
On January 14, 2003, at 1407 eastern standard time, a McDonnell Douglas MD-11-C, Italian registration I-DUPA, operated by Alitalia Airlines as flight 604, was reported to have landed at John F. Kennedy International Airport JFK, Jamaica, New York, with no lateral roll control. There were no injuries to the 3 Italian certificated pilots, 8 flight attendants, or 131 passengers. Visual meteorological conditions prevailed. Flight 604 was conducted on an instrument flight rules (IFR) flight plan under 14 CFR Part 129.
The airplane was a combi configuration, with passengers in the front, and cargo in the aft portion of the cabin. The flight departed from Milan, Italy at 0446. There were no reported problems with the departure or en route phases of the flight.
According to a written statement from the captain, and a follow-up telephone interview, the flight was about 70 to 80 nautical miles east northeast of JFK, at an altitude of FL 380 (38,000 feet), when he first noticed a problem. He had received a radar vector and attempted to use the auto-pilot to make the heading change. When the turn command was applied, the autopilot performed an uncommanded disconnect. The captain then elected to hand fly the airplane and observed that the control wheel would not move in the lateral or roll axis (ailerons) of the airplane. However, the control wheel was free to move in the longitudinal axis (elevator), and the rudder pedals were free to move about the yaw axis. The captain declared an emergency and requested a long approach to runway 31L at JFK.
In preparation for landing, the flight crew extended the leading edge wing slats without incident. As the flap handle was positioned to extend trailing edge wing flaps, a warning light illuminated which indicated a difference between the selected flap position and the actual flap position. The flight crew elected to continue with a no-flap approach to runway 31L. The wind was aligned with the runway, and the pilot landed without further incident. After landing, the airplane taxied to the gate where the passengers deplaned through the jetway.
Post-flight examination of the airplane revealed ice had encased multiple control cables in the wheelwell area, including both aileron, and flap control cables. Further examination revealed that a potable water line, aft of the lavatory, adjacent to door 3R, had become disconnected and the bays beneath the floor boards contained water. The number 1 and 2 potable water bottles, each with a capacity of 63 gallons, were reported to be at 12 percent capacity, and empty, respectively.
The Safety Board has requested that the line that became disconnected, and the flight data recorder data be forwarded to the Safety Board laboratory for further examination.

No ailerons . . . sounds pretty spooky to me. Excellent piloting skills though, landing that M11 without ailerons. I have seen quite some "bad" MD-11 landings, even with all flight control functions fully available!
Is this standard training for cockpit crew? Do they regurlarly train for events like this where one of the main flight control functions is unavailable?

Voi ne sapevate qualcosa?
Buona notte
