What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On 12/06/01 at approximately 0830 the commercial pilot landed the AS-355 helicopter on a cement "pad" at point conception, CA. This "pad", which had been used by this pilot in this helicopter several times a year for the past 14 years, is located on a U.S. Coast guard lighthouse facility. After this landing the helicopter was shut down. As the baggage was being unloaded, a passenger's foot broke through the cement and a void was discovered below the cement. Before the pilot could start the helicopter to move it, the cement under the helicopter failed, causing the helicopter to roll left with the nose and tail cone resting on the uppper edges of a 10' x 20' underground tank. There were no injuries to any personnel.
