On 14 February 2006, during the destructive wing strength certification test on MSN5000, the test wing of the A380 failed at 145% of the limit load, short of the required 150% level. Airbus announced modifications adding 30 kg (66 lb) to the wing to provide the required strength. On 26 March 2006, the A380 underwent evacuation certification in Hamburg. With 8 of the 16 exits randomly blocked, 853 mixed passengers and 20 crew exited the darkened aircraft in 78 seconds, less than the 90 seconds required for certification. Three days later, the A380 received European Aviation Safety Agency (EASA) and United States Federal Aviation Administration (FAA) approval to carry up to 853 passengers.
