Narrative:
The Cessna 550 Citation II encountered wind shear during a LOC DME approach to runway 03 at Lugano Airport, Switzerland.
The aircraft touched down at Vref (108 kts) + 10 kts and bounced two times and touched down nose gear first.
During landing rollout the nose landing gear collapsed.

Causes
The accident was due to:
- A non-stabilized approach because of wind shear;
- Uncoordinated action in using "Reverse" and "Speedbrakes" after a relatively hard landing at excessive speed
- A lack of ATIS warning about wind shears.
