## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Subsequent to accidents involving Fuel Tank System explosions in flight * * * and on [the] ground, the FAA has published Special Federal Aviation Regulation No. 88 (SFAR-88) in June 2001 [which] required [conducting] a design review against explosion risks. * * * * * The potential of ignition sources (in certain fuel pumps, fuel switches, refuel shutoff valves, and optical sensors/mechanical switches), in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
