Pratt & Whitney Canada’s PW610F turbofan engine will power the Eclipse 500, the two companies announced on February 19, ending nearly three months of speculation about how Eclipse would get the program moving again after it terminated its agreement with Williams to use the EJ22 engine.
BOMBARDIER LEARJET 25C, LEXINGTON, KY., AUG. 30, 2002–The captain’s addition of forward thrust during the landing rollout, resulting in a lack of braking effectiveness, was listed by the NTSB as the cause of a runway overrun accident by Learjet 25C N45CP. A factor was the captain’s inability to deploy the thrust reversers for undetermined reasons.

It is said to even cut maintenance costs.
For developers of unmanned aerial vehicles (UAVs), combining sufficient speed, a high payload, maneuverability, low fuel consumption, high endurance and minimum takeoff and landing distances is a dream scenario. Italian company Nimbus is trying to make this proposition a reality with its Metaplane.
Stage III Technologies, which received an STC two years ago this month for its hush kit for Gulfstream IIs and IIIs, plans to have its long-awaited first installation under way in August at Western Jet in Van Nuys, Calif.
