Discussion

The FAA commissioned the Sandia National Laboratories to perform an independent study on the effectiveness of ignition source prevention measures in airplane fuel tanks. Sandia National Laboratories documented the results of its study in a technical report titled “Assessment of the Effectiveness of Special Federal Aviation Regulation (SFAR) 88 Airworthiness Directives (ADs) in Preventing Ignition Sources.” This report supports the FAA's NPRM (published on November 23, 2005 (70 FR 10922)) that proposes to require operators and design approval holders of transport category airplanes to reduce fuel tank flammability exposure, which, in combination with previous ignition source minimization, would greatly reduce the chances of a catastrophic fuel tank explosion.

The report is currently undergoing a peer review, as required by the Office of Management and Budget's “Final Information Quality Bulletin for Peer Review.” The FAA will add the report of the peer review to the public docket and make it available for public comment.
