Cockpit voice recorders that use magnetic tape would no longer be permitted because they're not as reliable as digital recorders and more vulnerable to damage.

Flight data recorders, which record the movement of cockpit controls, would sample data more often and retain 25 hours of information . Now, they have to measure data every second in airplanes; the proposal would require sampling every 1/16th of a second. For helicopters, they will have to sample four times a second rather than the two times per second now permitted.

"Good data is often the Rosetta stone to deciphering what happened in an aircraft incident and what could happen in an accident," FAA Administrator Marion Blakey said.

The public will have a chance to comment on the proposal, which is expected to take effect by the end of next year.

The FAA estimates the new rules will apply to about 9,600 aircraft with 10 or more seats and cost the aviation industry $256 million.

New aircraft must have recorders that meet the new standards two years after the rule is in force.
