9/11 Aircraft 'Black Box' Serial Numbers Mysteriously Absent
Of all major U.S. airline crashes within the U.S. investigated and published by the National Transportation Safety Board during the past 20 years, the 9/11 'black boxes' are virtually the only ones without listed inventory control serial numbers.
NTSB American Airlines flight 77 flight data recorder report, not noting a device serial number:
NTSB United Airlines flight 93 flight data recorder report, not noting a device serial number:
With flight data recorder serial number data that is virtually always provided within NTSB reports of major U.S. commercial airline crashes that occur within U.S. territory, one can trace an installed device to a particular registered aircraft through manufacturer or airline records.
The following e-mail was provided by a Susan Stevenson of the NTSB on 12/26/2007, in response to a 12/16/2007 public correspondence e-mail inquiry:
"Yes. NTSB investigators rarely encounter a scenario when the identification of an accident aircraft is not apparent. But during those occasions, investigators will record serial numbers of major components, and then contact the manufacturer of those components in an attempt to determine what aircraft the component was installed upon."
Because of the criminal nature of the 9/11 attacks, the FBI became the lead investigative agency into the 9/11 aircraft mishaps, along with the requested aid of the NTSB. It is possible that the FBI seized FAA 9/11 aircraft records containing component serial number data for aircraft identification purposes and that the FAA no longer possesses them.
By document labeled "Testimony of Marion C. Blakey, Chairman National Transportation Safety Board before the Committee on Commerce, Science and Transportation United States Senate", it is indicated that the NTSB assisted the FBI with the process of "aircraft parts identification" regarding the said aircraft.

The only other instance of undocumented FDR serial numbers following a major U.S. commercial aircraft crash within U.S. territory during this 20 year period, seems to be a little known mishap that oddly, occurred on September 11, 1991, exactly 10 years before the September 11, 2001 terrorist attacks. This report also did not list a FDR manufacturer or model number, possibly because the accident was immediately determined to be the result of negligence on the part of aircraft maintenance personnel.
Continental Express Flight 2574, September 11, 1991, EMB 120, 14 Dead, FDR Manufacturer, Model & Serial Number Not Available.
