U.S. Rep. Duncan Hunter (R-San Diego), the senior Republican on the House Armed Services Committee, has asked the Marine Corps to release all maintenance records of its F/A-18D Hornet fighter jets after one crashed into a San Diego neighborhood Monday, killing four members of a young family.

The crash was apparently caused by "power failure" and was likely unrelated to last month's discovery of cracks on the wings of more than a dozen aircraft at Marine Corps Air Station Miramar.

Nevertheless, Hunter wants to see all the maintenance records to determine what really caused the tragedy.

"It is important that we gain a complete understanding of what went wrong," Hunter said in a statement."

UPDATE: U.S. Senators Barbara Boxer and Dianne Feinstein issued a joint statement Wednesday calling for a prompt investigation into the causes of the crash.

"We understand that the Marine Corps is conducting an investigation into the crash and we ask that it be completed as swiftly as possible and that the results be made immediately available to the public," the two long-time senators from California said. "It is our hope that you will also conduct a full review of the F/A-18D fleet to ensure that other aircraft are not prone to similar problems."
