Diamond Aircraft is delaying the D-Jet program to install an engine with greater power output. The new engine is the -19 version of the Williams International FJ33-4A, delivering 1,900 pounds of thrust compared with the original -15’s 1,564 pounds. Coincidentally, that is almost the same engine change made by Spectrum Aeronautical with its S-33 Independence VLJ, switching from the FJ33-4A-15 to a 1,750-pound-thrust version of the -19.

Late last week, Diamond Aircraft selected a more powerful version of the Williams FJ33 turbofan–the FJ33-4A-19–for its single-engine D-Jet. With 1,900 pounds of thrust versus 1,564 pounds for the originally planned FJ33-4A-15, the more powerful engine offers “a potential future performance upgrade path” for the very light jet.

Ground test runs started last month on the 4,900-pound-thrust TFE731-50, Honeywell’s newest business jet engine. The engine, featuring integrated nacelle and thrust-reverser systems, produced more than 5,000 pounds of thrust in a test cell on its first run, the company said. The engine is scheduled to begin flight testing on Honeywell’s Falcon 20 this summer.

The termination of the agreement between Eclipse Aviation and Williams International, announced the day before Thanksgiving, is seen as a major setback for the Eclipse 500 very light jet program by many observers– particularly (and predictably) by the battalions of skeptics who have questioned the viability of the program since it was revealed in March 2000.

At last month’s NBAA Convention, Spirit Wing Aviation of Edmond, Okla., announced that it will begin producing its “virtually new” Spirit-Lear early next year. The company said the $2.2 million SpiritLear–a re-engined Learjet 25–will be priced lower than any other airplane offering its combination of speed, range and passenger capacity.

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.

Really Quiet has doubled the warranty on its Stage 3 hush kit and thrust-reverser system for the Gulfstream II. The new warranty is two years, 1,000 hours or 500 cycles, whichever comes first. Really Quiet of Reston, Va., was the first of two companies to receive an STC for installation of hush kits on Spey-powered Gulfstreams.
