Détails:
An ATR-72 passenger plane, registered YR-ATS, sustained substantial damage in a landing accident at Roma-Fiumicino Airport (FCO), Italy. Of the 50 occupants, five sustained serious injuries.
Alitalia flight AZ1670 had departed Pisa-Galileo Galilei Airport (PSA) on a domestic flight to Roma-Fiumicino Airport (FCO). This flight was operated by Carpatair on behalf of Alitalia.
The airplane flew the approach in strong cross wind conditions with wind shear reported at runway 16L some fifteen minutes before the landing. Shortly before touchdown the airplane suddenly lost altitude and impacted the runway with the nose landing gear. This was at a distance of 567 meters from the runway threshold.
It bounced three times, causing the nose and main gear to collapse. The airplane slid off the left side of the runway and came to rest in the grass near taxiway DE, at a distance of about 1780 meters from the runway threshold. The aircraft had also performed a rotation on the vertical axis of 170°, thus assuming a definitive orientation of about 330° magnetic. It came to rest 400 m from fire station no. 1. However, it took the fire services ten minutes to reach the airplane because they were not aware of the precise location of the accident.

The airplane landed in strong winds from 250 degrees on runway 16L. Runway 25 at Fiumicino was Notamed not available for landings due to work in progress.
The Fiumicino Notam reported at the time of the accident of the following limitations of the runway 16L ILS:
- LOCALIZER AT 17NM MRA 3000FT AND AT 25NM MRA 4000FT
- GLIDE PATH COVERAGE REDUCED AT 8.5NM
