TBO for the engine is 5,000 hours, with no hot section intervention required, 1,000 hours longer than the Williams engine on the CJ3. The Phenom 300 enjoys a 5-year/5,000 hour warranty on Embraer parts, similar to Cessna’s CJ3 warranty. Requiring just a single scheduled annual maintenance intervention, the Phenom should cost less to maintain.Fuel burn is greater than the CJ3’s, although, in fairness, the Phenom is bigger with a larger useful load. While the Phenom goes about 35 knots faster at FL300-FL320, the airplane is a little slower in the higher levels, where we typically fly. At FL450, we saw 394 knots true, burning about 130 lbs/hr more fuel (900 lbs/hr vs. 770 lbs/hr). Temperature at altitude was -65C SAT, a little colder than ISA.The Phenom may not travel any farther than the CJ3 on a full fuel tank at high-speed cruise. In the CJ3, we routinely see 1,650-1,700 NM, with reserves. (Cessna claims 1,881 NM, using NBAA criteria.) The Phenom advertises 1,900NM+, but that is at long-range cruise. Still, independent of thrust settings, the Phenom can cover its max distance carrying 1,142 lbs of payload while the CJ3 is limited to a max of 600 lbs.SystemsCJ3 pilots will find the systems in the Phenom well thought-out and, in6 • TWIN & TURBINENOVEMBER 2014
