About six years after the first flight of Bell’s newest and largest civil helicopter, the 525 Relentless, its development and flight-test certification program is nearing an end. "Generally speaking, the plan is to complete our testing required for certification in the first half of this year,” Bell 525 senior program specialist Brendan Lanigan told AIN. “We’re actually running out of tests to perform. So that’s exciting for those of us that have been involved in the program for quite some time

Specifically, company flight testing is complete while ground endurance testing is 50 percent complete and FAA pilot testing is 65 percent complete, noted 525 program v-p Byron Ward during a conference call with reporters on March 24.
