Pressurization Fix For Encores
Freezing Valve Cited...
Cessna will be notifying Encore owners that a pressurization system problem needs fixing. Cessna spokeswoman Jessica Myers told AVweb Wednesday that at least 71 of the seven-place twin jets will be modified, under warranty, to address the problem. The tally could rise slightly because it doesn't include sales made in the current quarter. Myers said water freezing inside the plane's emergency pressurization valve is the cause of the difficulty. The fault causes variations in pressurization but Myers said there has never been a failure of the system or any emergency descents required. She said there is no immediate safety concern. According to Myers, "It's important to note that there aren't any impending actions by the FAA that would affect flight operations (of the Encore)." The fix involves moving the valve, presumably to a warmer location. Myers said the repairs will be done at no cost to Encore owners and a Service Bulletin will be issued in January. The Encore is in the same family as the Ultra and Excel Cessna bizjets and was introduced in 2000.
...NetJets Grounds Its Encores
One of Cessna's biggest customers, fractional ownership giant NetJets, is taking no chances and has grounded all its Encores. "We've been working with NetJets on this," said Myers. NetJets Maintenance Supervisor Rod Plumley confirmed to AVweb that all seven of its Encores have been pulled from service. "Cessna is re-engineering some part of the system," said Plumley. Plumley said NetJets had recurrent problems with their Encores and that was enough to yank them off the line. "Safety is our number-one concern," he said. "We are only going to fly anything as close to perfect as possible." Plumley said any fractional owners with flights booked on an Encore will be upgraded to a larger aircraft until the problems are sorted out. NetJets operates more than 450 aircraft worldwide.
