Drobný update z Flight International - (anglicky, bo nevím jak se to řekne ;o)
Corrosion of the internal threads of the starboard main-gear actuating piston, which controls gear deployment, led to the piston's rod end becoming detached from the piston. The main landing gear on the Q400 retracts rearwards into the cavity behind the engines. Damage to the actuator piston can cause the undercarriage to deploy too quickly.
